[0002] Canalization is a way of separating or controlling conflicting traffic flows by combining guide islands with road markings, so that the traffic flows enter the predetermined route, thereby meeting the basic requirements of the flat intersection.

It should be understood that the examples of the present application are mainly to illustrate possible implementation manners of the technical solutions of the present application, and should not be interpreted as the only limitation of the technical solutions of the present application.
[0053] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. If there is any inconsistency, the meaning as explained in the present specification or derived from the content described in the present specification shall prevail. In addition, the terms used in the present application are only for the purpose of describing the embodiments of the present application, and are not intended to limit the present application.
[0054] The intelligent traffic signal control system is a system that uses signal control for intersections, pedestrian crossings, and ring road entrances in urban road traffic management systems, involving traffic engineering design, vehicle information collection, data transmission and processing, control model algorithm and simulation analysis, optimization control signal, and traffic flow adjustment. The intelligent traffic signal control system in each sub-area is both a relatively independent traffic control system and a part of the entire regional intelligent signal system.
[0055] The traffic signal system (Traffic Signal Control System) is a system for road traffic control, which is composed of road traffic signal control machines, road traffic signal lights, road traffic flow detection equipment, communication equipment, central control computers, and related software.
[0056] The signal machine generally includes the aforementioned road traffic signal control machine and related software, and is arranged at each level of signal control intersection (hereinafter referred to as intersection), i.e. at the roadside. When the signal machine is in the central control mode, it receives the traffic control instructions issued by the traffic control center to control the light color of the road traffic signal lights arranged at the roadside. When the signal machine is in the local mode, it controls the light color of the road traffic signal lights arranged at the roadside according to the preset scheme stored locally. Through pre-configuration, the signal machine can actively upload the signal cycle, phase, phase light state, and traffic flow data of the intersection to the traffic control center.
[0057] Each level of traffic signal system includes a traffic control center, which includes the aforementioned central control computer and related software, and is used to obtain the state of the signal machine and other traffic facilities (such as signal lights) at the roadside, or to generate traffic control instructions that the signal machine needs to execute. Generally, each signal machine and each traffic control center are network communication nodes in a local area network, and are connected and communicate data through the communication equipment arranged respectively.
[0058] The traffic signal system at each level is usually used in cooperation with the intelligent traffic integrated command platform at each level, and serves as the traffic control center and the traffic dispatch center, respectively. Therefore, the service range of the intelligent traffic integrated command platform at each level is determined by all the signal machines connected to the network thereof.
[0059] The intelligent traffic integrated command platform at each level sets the central dispatch platform as the traffic dispatch center, which is usually deployed in the traffic dispatch command department at each level, and usually includes a Web terminal for receiving traffic dispatch instructions.
[0060] When the traffic signal system at each level is in normal operation, a plurality of basic data, such as area, sub-area, signal control intersection, cycle, lane, phase, stage, and timing scheme, need to be set in the software and hardware in the system.
[0061] Signalized Intersection: An intersection where vehicles and pedestrians are controlled by road traffic signals.
[0062] Sub Area: A collection of one or a plurality of signal control intersections that adopt the same traffic control strategy.
[0063] Area: A collection of one or a plurality of sub-areas.
[0064] Cycle: The time required for the signal light color to display one cycle in the set stage order. Usually, one signal cycle includes a plurality of signal stages. The aforementioned fixed cycle mode usually refers to the signal machine performing each signal cycle in a cycle.
[0065] Stage: The basic time unit of the signal cycle, the release time period with the same light color and the transition interval.
[0066] Inter Stage: The transition time from the end of the previous stage to the beginning of the next stage.
[0067] Phase: A set of green, yellow, and red light changes allocated to one or a plurality of independent traffic flows in one signal cycle.
[0068] Min Green Time: The minimum green light time required when a certain phase starts green light for traffic safety reasons. Usually, one stage includes at least one phase, such as the pedestrian phase and the motor vehicle phase. Usually, the maximum value of the minimum green light of the motor vehicle phase is taken as the minimum green time of the stage.
[0069] With the increasing traffic congestion in cities, for the complex traffic conditions at intersections, the intersection traffic signal control usually configures multiple sets of signal plans and respectively dispatches them according to the traffic conditions at the intersection, or controls the signal plans based on the real-time traffic flow data collected by the intelligent devices such as detectors arranged at the intersection. Therefore, the signal machine for controlling the road traffic signal lights operates in any one of the local mode, the sensing mode or the plan coordination mode. For example, to execute the temporary dispatch task issued by the traffic dispatch department, first, a temporary plan is generated by modifying the preset plan stored locally in the signal machine. Then, the newly generated temporary plan is stored in the signal machine locally. The signal machine operates in the plan coordination mode and executes the temporary plan within the effective time period of the temporary plan.
[0070] In modern urban traffic signal control, in order to ensure the smoothness of the main route, trunk coordination control (corresponding to the aforementioned plan coordination mode of the signal machine operation) is often used, so that the vehicle flow that is given priority to keep smooth can pass through its road control area with "one-way green light". As a method of urban trunk control, "green wave" traffic is to install automatic control signal lights with specific cycle and green ratio at adjacent or related intersections on the road, so that the vehicle flow on the main road can avoid red light and encounter green light when it reaches the front intersection. This "green wave" traffic can reduce the vehicle delay before the intersection and improve the average driving speed and traffic capacity on the road. At this time, the signal machines at each intersection are in the plan coordination mode in the local mode.
[0071] The temporary timing plan is usually a new timing plan formed by modifying the release time period of at least one phase or modifying the release order (such as modifying the sequence number of each signal phase) in the preset plan of the intersection according to the traffic operation of the intersection. The temporary plan is usually executed temporarily within a specified time interval (i.e. the effective time period described below) to adjust the traffic flow, alleviate traffic congestion or improve road traffic efficiency.
[0072] Usually, one signal machine can control multiple intersections, such as 4 intersections, so it can execute the temporary plan for at least one intersection respectively. When one phase board is used to control 6 phases, for an intersection with 18 phases, usually 3 phase boards are needed to realize this. At this time, each phase board includes 6 control ends, and each control end is used to control 3 possible lamp color output terminals of the corresponding phase, such as red light R output terminal, green light G output terminal or yellow light Y output terminal, so that the lamp color on the phase is lit according to the preset sequence.
[0073] The card mouth is usually used as a subsystem supervised by the department of road traffic. The card mouth monitoring is usually equipped with a light supplement lamp, a ground inductor, a high-definition digital camera or a camera head and a network access device, and is used in cooperation with a remote traffic management software. By using advanced photoelectric, computer, image processing, pattern recognition, WEB data access and other technologies, the front feature image of each motor vehicle on the road surface, the panoramic image of the vehicle and the real-time video stream on the road surface are continuously photographed, recorded and processed. In this way, the camera head arranged at the intersection is relied on, and intelligent instruments and software are combined to realize intelligent management and control of road traffic, realize the statistics of current traffic flow, section vehicle counting, vehicle feature retrieval (such as whether the license plate number meets the requirements of limited driving) and part of the illegal snapshot function (such as whether the driver wears a safety belt, whether to make a call, etc.).
[0074] Currently, the channelization map is usually realized by using scalable vector graphics (SVG). In the channelization map editing scheme in the Web mode, dojo is usually used to encapsulate the channelization map. However, the use of dojo to realize the channelization has the problems of large file size, very slow initial download and thus leading to unsmooth loading and the like. In addition, the class library of dojo is not documented, and the usability is not strong, and the development efficiency is low.
[0075] As shown in Figure 1 The intersection channelization map configuration method of the embodiment of the application comprises the following steps:
[0076] S10: obtaining information uploaded by each device of an intersection;
[0077] S20: matching a configurable element according to the information uploaded by each device of the intersection, and displaying the configurable element on an intersection channelization map configuration page;
[0078] S30: configuring a channelization map of the intersection according to the operation of a user on the configurable element on the intersection channelization map configuration page.
[0079] In the above, the information uploaded by each device of an intersection is obtained; a configurable element is matched according to the information uploaded by each device of the intersection, and is displayed on an intersection channelization map configuration page; a channelization map of the intersection is configured according to the operation of a user on the configurable element on the intersection channelization map configuration page, so as to generate a channelization map of the intersection and store the channelization map data corresponding to the intersection. By using the channelization map data, the channelization map of the intersection or the channelization map of the associated intersection can be subsequently echoed or displayed.
[0080] Thus, based on the information uploaded by each device of the intersection in real time or periodically, the configurable elements are automatically matched according to the information uploaded by each device, and are displayed on the intersection channelization map configuration page. At this time, the intersection channelization map configuration page displays the partially edited channelization map. Thus, the formatted channelization map obtained by the matching can be used as the partially edited channelization map, so that the efficiency of configuring the channelization map of the intersection is improved. Further, according to the operation of the user on the configurable elements on the intersection channelization map configuration page, the channelization map of the intersection is configured. Based on the aforementioned partially edited channelization map, the intersection can obtain a more accurate channelization scheme through real-time human-computer interaction, and the channelization map can be more flexibly and finely configured until the channelization map of the intersection is completely edited. Thus, the channelization map of each intersection is accurately, flexibly, richly and efficiently configured in a what-you-see-is-what-you-get manner and a friendly human-computer interaction interface, which is beneficial to improving the generation efficiency of the intersection channelization map.
[0081] Thus, the intersection channelization map configuration method of the embodiment can more quickly realize the visualization of the channelization map, and obtain and configure the channelization map data of the intersection, such as the phase, control mode, road name, associated intersection, detector, camera and the like.
[0082] After the intersection is channelized, the devices and traffic infrastructures usually arranged on the roadside include detectors, cameras, signal lights, diversion signs laid on the road surface, signal machines, light position plates, roundabouts, lanes, green belts, isolation belts and isolation water horses. The signal machine arranged on the road will periodically or in real time report the traffic data of the intersection, including the phase, phase, traffic flow, light state and the like corresponding to each lane of the intersection.
[0083] In some embodiments, the matching of the configurable elements according to the information uploaded by each device of the intersection includes:
[0084] The information uploaded by at least one device is sorted according to the matching accuracy of the configurable elements, a plurality of configurable elements with an accuracy greater than a preset value are determined, and are displayed on the intersection channelization map configuration page.
[0085] Thus, based on the information uploaded by each device of the intersection in real time or periodically, the configurable elements are automatically matched according to the information uploaded by each device, and are displayed on the intersection channelization map configuration page. At this time, the intersection channelization map configuration page displays the partially edited channelization map. Thus, the formatted channelization map obtained by the matching can be used as the partially edited channelization map, so that the efficiency of configuring the channelization map of the intersection is improved. Further, according to the operation of the user on the configurable elements on the intersection channelization map configuration page, the channelization map of the intersection is configured. Based on the aforementioned partially edited channelization map, the intersection can obtain a more accurate channelization scheme through real-time human-computer interaction, and the channelization map can be more flexibly and finely configured until the channelization map of the intersection is completely edited. Thus, the channelization map of each intersection is accurately, flexibly, richly and efficiently configured in a what-you-see-is-what-you-get manner and a friendly human-computer interaction interface, which is beneficial to improving the generation efficiency of the intersection channelization map.
[0086] According to the matching accuracy, the information uploaded by the at least one device is sorted in the order of the configurable elements, including: arranging the configurable elements with higher matching accuracy in a more forward position, determining the configurable elements with an accuracy greater than a preset value as elements that need to be configured in the channelization map of the intersection, and preferentially displaying the configurable elements in the channelization map configuration page of the intersection.
[0087] In this way, by matching the configurable elements that need to be included in the channelization map in advance, the workload of subsequent human-computer interaction for configuring the intersection can be reduced, and the efficiency of generating the channelization map can be improved.
[0088] In some embodiments, the matching of the configurable elements according to the information uploaded by the devices of the intersection includes:
[0089] According to the image captured by the camera, the type of the intersection displayed in the image is recognized.
[0090] The lane element corresponding to the type of the intersection is matched, and the lane element is a configurable element for configuring a lane.
[0091] In some embodiments, in step S20, according to the image captured by the camera, the type of the intersection displayed in the image is recognized, including: processing the image captured by the camera arranged at the intersection, which displays a roundabout, each lane, a vehicle on each lane, a pedestrian, and a road surface guide sign, to determine the type of the intersection. As described above with respect to the card hole, a camera is usually arranged near the guide island of the intersection, facing the entrance direction of each lane, to realize the function of an electronic police, etc.
[0092] In this way, the type of the intersection included in the channelization map and the lane element of the intersection can be determined by using image processing technology, so as to realize the pre-processing of the partially edited channelization map, reduce the workload of subsequent human-computer interaction for configuring the intersection lane, and improve the efficiency of generating the channelization map.
[0093] In some embodiments, the intersection type table as shown in Table 1 is recorded in the channelization map data by the traffic signal system at each level, the intelligent traffic integrated command platform, and various signal machines.
[0094] Table 1. Intersection type table
[0095] No. Description 1 Roundabout 2 Ramp, driveway 3 Road segment (only two-way intersection) 4 T-intersection 5 Y-intersection 6 Offset T-intersection 7 Offset Y-intersection 8 Cross-intersection 9 Skew intersection 10 Multi-way intersection 11 Others
[0096] As shown in Figure 2A For any intersection, the default intersection type and intersection lane element are displayed in the intersection channelization map configuration page. By default, the intersection type is a three-way intersection, and three lane elements of two segments in each of the east, west, and south directions are displayed. As shown in Figure 2AAs shown, the configurable elements displayed by default on the intersection channelization map configuration page, from top to bottom, include: lane flow configuration elements (including a north-pointing arrow and clockwise and counter-clockwise rotation configuration elements, which operate in conjunction with the arrow), traffic light indicator configuration elements (associated with phase, clicking which triggers the phase configuration window and human-machine interaction controls), traffic light countdown indicator configuration elements (associated with phase, clicking which triggers the traffic light countdown indicator configuration human-machine interaction controls), road information configuration elements (as described below), detector configuration elements (associated with lanes, clicking which triggers the detector configuration window and human-machine interaction controls), compass configuration elements (associated with the channelization map, clicking which triggers the compass display controls), camera configuration elements (associated with lane entrance direction, clicking which triggers the camera configuration window and human-machine interaction controls), and associated intersection configuration elements.
[0097] In some embodiments, after determining the intersection type and intersection lane elements included in the channelization map using image processing technology, the intersection channelization map configuration page is displayed; accordingly, step S30 includes configuring the channelization map of the intersection based on the user's operation on the intersection lane elements on the intersection channelization map configuration page.
[0098] Specifically, after clicking on any lane element displayed on the intersection channelization map configuration page, a pop-up window will appear as follows: Figure 2A The left side shows the extracted intersection lane element configuration window. In the intersection lane element configuration window, for each lane element, selecting the number of lanes can determine whether the number of lanes recorded by each extracted lane element is accurate. If it is inaccurate, the number of lanes is modified to the actual number of lanes in that direction and segment of the intersection, and the channelization map data is updated. Configuring the rotation angle setting box can determine whether the lane direction recorded by each extracted lane element is accurate. If it is inaccurate, it is modified to the actual orientation degree corresponding to that lane at the intersection, and the channelization map data is updated. When it is determined that the distance between the lane position recorded by any extracted lane element and the roundabout is inaccurate, the translation control (including up, down, left, and right) of any lane element is selected to move the lane element, modify it to the actual distance between that lane and the roundabout in the intersection, and the channelization map data is updated.
[0099] In some embodiments, operation Figure 2AWhen the left part of the intersection lane element configuration window displays the controls, first select whether the lane exists. If the lane box is checked, at least one lane exists in this direction, and the adjacent lanes are separated by a dashed line. If the lane box is not checked, no lane exists in this direction. If a lane exists in this direction, the number of lanes can be increased to a maximum of 8 lanes or decreased to a minimum of 1 lane. If it is a special intersection (e.g., a blind end of a T-shaped intersection), the lane box is not checked, i.e., no lane exists in this direction. The lane direction corresponding to each lane can also be configured using the rotation angle setting box. The lane direction is rotated by the corresponding angle (e.g., set within ±360°) based on the default value according to the obtained rotation angle. Typically, the direction of the lane is the entrance direction of the south segment of the south-north direction when initialized. After the rotation angle setting box is configured, the lane direction can be any one of the following: any segment of the four directions of southeast, southwest, northwest, and northeast.
[0100] In some embodiments, as shown in Figure 2A According to the user's operation of the intersection lane element in the intersection channelization diagram configuration page, the channelization diagram of the intersection is configured, and the method further comprises:
[0101] After configuring each lane element in the intersection lane element configuration window, click the "save base map" control to save the channelization diagram data in the database. The channelization diagram data records the aforementioned data of each lane of the intersection, and will not be repeated here.
[0102] In some embodiments, as shown in Figure 2A In the intersection channelization diagram configuration page, there is a blue font import picture control in the right black background area. Clicking the import picture control, selecting the pre-stored intersection base map in the pop-up interactive control, can directly import the intersection base map drawn by the user in advance, as shown in Figure 2D It should be understood that the intersection base map drawn by the user in advance includes roundabouts, lanes, green belts, isolation belts, isolation water horses, etc., and does not include lane flow direction, signal lights, detectors, cameras, or associated intersections, etc. Other elements in the channelization diagram can be configured respectively according to the method described below, and the channelization diagram data is updated.
[0103] Typically, the lane data LaneParam of the channelization diagram data is recorded in the traffic signal system, intelligent traffic integrated command platform, and various signal machines, and is defined as follows:
[0104] <laneparam>
[0105] <crossid>Intersection No.< / crossid>
[0106] <laneno>Lane No.< / laneno>
[0107] <direction>Lane Direction< / direction>
[0108] <attribute>Lane Property< / attribute>
[0109] <movement>Lane Flow Direction< / movement>
[0110] <feature>Lane Feature< / feature>
[0111] < / laneparam>
[0112] The cross ID is an index or unique identifier for the intersection. The lane number LaneNo is usually numbered sequentially starting from 1, and has a value of two digits, such as 06 or 18. In general, the lane numbers of the lanes in the lane information of any intersection are different from each other, and thus can be used to uniquely identify the lanes. The lane direction Direction is the direction of the lane relative to the intersection, and the values are shown in Table 2. The lane attribute Attribute is shown in Table 3. The lane feature Feature is shown in Table 4. The lane movement Movement is shown in Table 5. In general, each lane on the road near the intersection is usually provided with a ground guide arrow to indicate the flow direction of the lane.

[0119] In general, the lane flow direction types with the main direction as straight, and other single or mixed lane flow directions related to the straight main direction are shown in Table 5. Because Table 5 does not distinguish the direction of the lane flow direction main direction, it is also necessary to derive scenarios in which the lane flow direction main direction is any one of south, north, east, or west according to the import direction of each lane in Table 2.

[0123] In some embodiments, the matching of the configurable elements according to the information uploaded by each device of the intersection further comprises:

[0126] In some embodiments, the lane flow type shown in the image is identified according to the image captured by the camera, including: processing the image captured by the camera arranged at the intersection and showing the lane, the vehicle on the lane, the pedestrian, and the road surface guide sign, to determine the lane flow direction of the lane. Referring to the foregoing description of the camera, the camera is usually arranged near the guide island of the intersection and towards the entrance direction of each lane to realize the function of electronic police, etc.
[0127] In this way, the lane flow direction data recorded in the channelization map data can be determined by using image processing technology, so that the default lane flow direction data is determined by preprocessing, which is beneficial to quickly edit the channelization map and reduce the workload of subsequent human-computer interaction for configuring the lane flow direction, thereby improving the efficiency of generating the channelization map.
[0128] In some embodiments, in the step S20, the lane flow direction element corresponding to the lane flow type is matched, and the lane flow direction element is an element for configuring the traffic flow direction sign of each lane entrance direction of the intersection.
[0129] According to the entrance direction of the lane and the lane flow type of the lane, the lane flow direction element corresponding to the lane flow type is matched, and the lane flow direction element is an element for configuring the traffic flow direction sign of each lane entrance direction of the intersection.

[0131] Specifically, according to the entrance direction of the lane and the lane flow type of the lane, the lane flow direction element corresponding to the lane flow type is matched, and the lane flow direction element is an element for configuring the traffic flow direction sign of each lane entrance direction of the intersection, and the lane flow direction element is operated on the intersection channelization map configuration page in a human-computer interaction manner to configure the corresponding lane sign in the entrance direction (i.e., the direction close to the roundabout) of each lane of the intersection, i.e., the foregoing traffic flow direction sign of each lane entrance direction.
[0132] In some embodiments, as Figure 2BAs shown, for any intersection, the configurable element with the light blue "north arrow" icon in the left optional area is the lane flow straight configuration element. Clicking the lane flow configuration element, a white background and khaki foreground human-computer interaction control element with the main direction as the north arrow icon (indicating south to north straight) and other arrow icons associated with the main direction as the north arrow icon can be displayed.

Specifically, referring to Table 3, other arrow icons associated with the main direction arrow icon can also be included, which will not be described again. By operating the foregoing lane flow configuration element, the corresponding lane flow element can be quickly and conveniently configured in the south to north south segment of the intersection, i.e. the import direction, which will not be described again.
[0133] In some embodiments, still referring to Figure 2B , for the current intersection, the configurable element with the white "counterclockwise rotation" icon in the right optional area is the lane flow counterclockwise rotation configuration element, and the configurable element with the white "clockwise rotation" icon is the lane flow clockwise rotation configuration element. Referring to Figure 2C, the two lane flow rotation configuration elements are jointly operated with the arrow mark of the main direction being the north direction, the man-machine interaction control is displayed as red, the lane flow configuration elements of the west-to-east section of the intersection in the west-to-east direction, i.e., the import direction, can be configured, the arrow mark of the main direction is the east direction, and other arrow marks associated with the arrow mark of the main direction.

In specific implementation, the other arrow marks associated with the arrow mark of the main direction can also be included, as shown in Table 3, and details are not described herein again. In specific implementation, the clockwise rotation configuration element or the counterclockwise rotation configuration element can be flexibly selected and used in combination with the arrow mark of the main direction being the north direction or the other arrow marks associated with the arrow mark of the main direction being the north direction, and details are not described herein again. In this way, the lane flow configuration elements of the west-to-east section of the intersection in the west-to-east direction, i.e., the import direction, can be quickly and conveniently configured by jointly operating the above lane flow rotation configuration elements.
[0134] In some embodiments, still referring to Figure 2B and Figure 2C , the two lane flow rotation configuration elements are jointly operated with the arrow mark of the main direction being the north direction, the lane flow configuration elements of the north-to-south section of the intersection in the north-to-south direction, i.e., the import direction, can be configured, the arrow mark of the main direction is the south direction, and other arrow marks associated with the arrow mark of the main direction. The other arrow marks associated with the arrow mark of the main direction in the south direction can include: a single arrow mark 21 for indicating a left turn from the north to the south, a single arrow mark 22 for indicating a right turn from the north to the south, a mixed arrow mark 23 for indicating a straight pass and a left turn from the north to the south, a mixed arrow mark 24 for indicating a straight pass and a right turn from the north to the south, a mixed arrow mark 25 for indicating a straight pass and a U-turn from the north to the south, a mixed arrow mark 26 for indicating a left turn and a U-turn from the north to the south, and a mixed arrow mark 27 for indicating a left turn and a right turn from the north to the south. In specific implementation, the clockwise rotation configuration element or the counterclockwise rotation configuration element can be flexibly selected and used in combination with the arrow mark of the main direction being the north direction or the other arrow marks associated with the arrow mark of the main direction being the north direction, and details are not described herein again. In this way, the lane flow configuration elements of the north-to-south section of the intersection in the north-to-south direction, i.e., the import direction, can be quickly and conveniently configured by jointly operating the above lane flow rotation configuration elements.
[0135] In some embodiments, still referring to Figure 2B and Figure 2C , the two rotating configuration elements are jointly operated with the arrow mark of the main direction being north, and an arrow mark of the main direction being west (for indicating straight east-west) can be configured on the lane of the intersection, such as rotating the arrow mark of the main direction being north by 270 degrees clockwise or rotating the arrow mark of the main direction being north by 90 degrees counterclockwise, and other arrow marks associated with the arrow mark of the main direction being west.

In specific implementation, the clockwise rotating configuration element or the counterclockwise rotating configuration element can be flexibly selected to be used in combination with the arrow mark of the main direction being north or the other arrow marks associated with the arrow mark of the main direction being north, and details are not described herein. In this way, the above lane flow direction configuration elements are jointly operated, and the corresponding lane flow direction elements can be quickly and conveniently configured on the east-west east segment of the intersection, i.e., the import direction.
[0136] As shown in Figure 2D , after the user uploads the channelization diagram base map, the two lane flow direction rotating configuration elements and the arrow mark of the main direction being north are jointly operated, and the white traffic flow direction marks of each lane import direction in the southeast, northwest, and other directions around the roundabout of the intersection are configured. For example, on the 5 lanes of the east-west east segment, from south to north, the lane flow direction elements are in turn a U-turn single arrow mark, a straight and left turn mixed arrow mark, a straight single arrow mark, a straight single arrow mark, and a straight and right turn mixed arrow mark.
[0137] In some embodiments, in the step S20, the configurable elements matched according to the information uploaded by each device of the intersection include at least one of the following:
[0138] When the information uploaded by each device of the intersection includes the information uploaded by the camera, the configurable elements matched include the camera mark;
[0139] When the information uploaded by each device of the intersection includes the light state information uploaded by the signal, the configurable elements matched include the signal light mark;
[0140] When the information uploaded by each device of the intersection includes the information uploaded by the detector, the matched configurable element includes the detector identifier.
[0141] With reference to the foregoing description of the card hole, generally, near the diversion island of the intersection, towards the entrance direction of each lane, a camera is arranged on the exit lane to realize the function of electronic police, etc. Therefore, when the information uploaded by each device of the intersection includes the information uploaded by the camera, such as the IP address of the camera, the device identifier of the camera, the intelligent transportation service platform to which the camera belongs, the sub-area to which the intersection set by the camera belongs, the intersection set by the camera, the signal machine corresponding to the intersection set by the camera, etc., the matched configurable element includes the camera identifier.
[0142] In some embodiments, in step S20, when the information uploaded by each device of the intersection includes the information uploaded by the camera, the matched configurable element includes the camera identifier; correspondingly, in step S30, the following steps are included: matching the camera identifier and displaying it on the intersection channelization map configuration page; and configuring the channelization map of the intersection according to the operation of the user on the camera identifier on the intersection channelization map configuration page.
[0143] As shown in Figure 2A , for any intersection, the configurable element with the "camera" text identifier in the left optional area is the camera configuration element. Operating the camera configuration element, such as selecting and clicking, a camera attribute configuration window as shown in Figure 2E is popped up. Operating each human-computer interaction control in the camera attribute configuration window, confirming that the intelligent transportation service platform to which the camera belongs, the sub-area to which the intersection set by the camera belongs, the intersection set by the camera, the signal machine corresponding to the intersection set by the camera, the IP address of the camera, the device identifier of the camera, etc. extracted according to the information uploaded by the camera can be configured to obtain the dome camera identifier displayed near the intersection island, the south segment of the south-to-north direction, that is, the exit direction, and the gun camera identifier displayed near the intersection island, the west segment of the east-to-west direction, that is, the exit direction, as shown in Figure 2F .
[0144] In this way, according to the information uploaded by each device of the intersection, the matched configurable element is determined to include the camera identifier through preprocessing, and the default value of each human-computer interaction control for display in the camera attribute configuration window is extracted, which can reduce the workload of subsequent human-computer interaction for configuring the camera identifier and improve the efficiency of generating the channelization map.
[0145] Generally, the following phase data PhaseParam is recorded in the channelization map data of each level traffic signal system, intelligent traffic integrated command platform, and each type of signal machine, which is defined as follows:
[0146] <phaseparam>
[0147] <crossid>Intersection No.< / crossid>
[0148] <phaseno>Phase No.< / phaseno>
[0149] <phasename>Phase Name< / phasename>
[0150] <attribute>Phase Feature< / attribute>
[0151] <lanenolist>
[0152] <!-- phase release lane number list -->
[0153] <laneno>Lane No.< / laneno>
[0154] …
[0155] < / lanenolist>
[0156] <peddirlist>
[0157] <!-- phase release pedestrian sidewalk direction -->
[0158] <direction>< / direction>
[0159] <direction>< / direction>
[0160] …
[0161] < / peddirlist>
[0162] < / phaseparam>
[0163] The intersection number CrossID is an index or a unique identifier for the intersection saved locally by the signal. The phase number PhaseNo is numbered sequentially from 1 and takes a 2-digit value, such as 18 or 36. Generally, the phase numbers of the phases in the phase information of any intersection are all different, and thus can be used to uniquely identify the phases. The phase name PhaseName can be defined flexibly for clarity and ease of understanding. The phase feature Feature usually takes 3 values, such as 1 for a key phase, 0 for a non-key phase, and 9 for others. The phase release lane number list LaneNoList usually contains at least one lane number <laneno>Lane number as in the preceding lane data. The list of directions PedDirList in which the phase releases the pedestrian crosswalk usually contains at least one direction of the pedestrian crosswalk <direction>, the value is shown in Table 1. If there is a same direction segmented release, a bit can be added after the direction to describe the release segment.
[0164] Generally, near the diversion island of the signal light controlled intersection, a plurality of sets of signal lights are arranged on the entrance direction of each lane on the exit lane to realize the traffic flow control by the signal light color change of the signal machine. The signal machine arranged at the intersection actively uploads the phase light state or traffic flow data of each intersection. The phase light state of the intersection includes the real-time light state information of all phases of the intersection, and the light state value of each phase can be off light, red light, yellow light, green light, red yellow.
[0165] Therefore, when the information uploaded by each device of the intersection includes the light state information uploaded by the signal machine, such as the light state value, the device identifier of the signal light, the phase to which the signal light belongs, the intelligent transportation service platform to which the signal light belongs, the sub-area to which the intersection where the signal light is arranged belongs, the intersection where the signal light is arranged, the signal machine corresponding to the intersection where the signal light is arranged, etc., the configurable element that can be matched includes the signal light identifier. It should be understood that, according to the light state value corresponding to each phase, the green light duration, yellow light duration, red light duration, countdown duration, transition duration, etc. of each phase can be determined.
[0166] In some embodiments, in step S20, when the information uploaded by each device of the intersection includes the light state information uploaded by the signal machine, the configurable element that can be matched includes the signal light identifier; correspondingly, in step S30, the signal light identifier is matched and displayed on the intersection channelization map configuration page; and the channelization map of the intersection is configured according to the operation of the user on the signal light identifier on the intersection channelization map configuration page.
[0167] As shown in Figure 2A , for any intersection, the configurable element with the "red yellow green" light color identifier in the left optional area is a signal light configuration element. When the signal light configuration element is operated, such as being selected and then clicked, a signal light phase configuration window as shown in Figure 2G is popped up. The intelligent transportation service platform to which the signal light belongs, the sub-area to which the intersection where the signal light is arranged belongs, the intersection where the signal light is arranged, the signal machine corresponding to the intersection where the signal light is arranged, the IP address of the signal light, the device identifier of the signal light, etc. extracted according to the information uploaded by the signal light can be configured to obtain, for example, as shown in Figure 2D The illustrated signal light identification is shown near the intersection island, the south-to-north direction north segment, the north-to-south direction south segment, the east-to-west direction west segment, and the west-to-east direction east segment. It should be understood that the phase data of each signal light, such as the green light duration, yellow light time, red light duration, countdown duration, transition duration, and the like, can be determined and updated to the channelization map data.
[0168] In this way, according to the information uploaded by the devices of the intersection, the matched configurable elements include the signal light identification, and the default values of the human-computer interaction controls used for display in the signal light attribute configuration window are extracted, which can reduce the workload of subsequent human-computer interaction for configuring the signal light identification and improve the efficiency of generating the channelization map.
[0169] At the signal light control intersection, the signal light countdown plays an auxiliary role in reminding the driver to recognize the change of the traffic signal light. When the signal light changes from green to red, it usually goes through the following process: green light-yellow light (at least 3 seconds)-red light. Before the red light is on, the driver has at least 3 seconds of buffer time, and the driver can determine whether the vehicle can safely pass through the red-green light intersection within the 3 seconds. If the vehicle has passed the stop line when the yellow light is on, it can continue to pass through; but if it passes the stop line when the red light is on, it is a violation of the law of running a red light. The at least 3 seconds is the signal light countdown described below.
[0170] In some embodiments, when the information uploaded by the devices of the intersection includes the light state information uploaded by the signal machine, the matched configurable elements further include the signal light countdown identification in step S20; accordingly, step S30 further includes: matching the signal light countdown identification and displaying it on the intersection channelization map configuration page; and configuring the channelization map of the intersection according to the user's operation of the signal light countdown identification on the intersection channelization map configuration page.
[0171] As shown in Figure 2A For any intersection, the configurable element with the "123" digital identification in the left selectable area is the signal light countdown identification configuration element. In combination with the previously configured lane entrance direction traffic flow identification and the signal light countdown identification configuration element, the signal light countdown identification configuration element is dragged to the entrance lane facing each signal light identification, and the entrance direction traffic flow identification corresponding to the phase to be configured is selected and clicked. The countdown duration configuration window is popped up to confirm or configure the countdown duration corresponding to the phase. As shown in Figure 2D As shown, the signal lamp countdown time length of the left turn phase and the signal lamp countdown time length of the straight running phase are configured in the south-to-north direction south section, i.e. the import direction, near the roundabout of the intersection; the signal lamp countdown time length of the left turn phase and the signal lamp countdown time length of the straight running phase are configured in the north-to-south direction north section, i.e. the import direction; the signal lamp countdown time length of the left turn phase and the signal lamp countdown time length of the straight running phase are configured in the east-to-west direction east section, i.e. the import direction; and the signal lamp countdown time length of the left turn phase and the signal lamp countdown time length of the straight running phase are configured in the west-to-east direction west section, i.e. the import direction.
[0172] In this way, according to the information uploaded by each device of the intersection, the matched configurable elements are determined to include the signal lamp countdown identification configuration control through pre-processing, and the default values of each human-computer interaction control used for display in the signal lamp countdown configuration window are extracted, so that the workload of subsequent human-computer interaction for configuring the signal lamp countdown identification can be reduced, and the efficiency of generating the channelization map can be improved.
[0173] In some embodiments, the traffic signal system at each level, the intelligent traffic integrated command platform, and various signal machines uniformly record the following detector data in the channelization map data:
[0174] <detparam>
[0175] <detid>Detector No.< / detid>
[0176] <distance>Distance from stop line< / distance>
[0177] <crossid>Intersection No.< / crossid>
[0178] <lanenolist>
[0179] <!-- List of lane numbers (corresponding to lane numbers in lane data) -->
[0180] <laneno>Lane No.< / laneno>
[0181] …
[0182] < / lanenolist>
[0183] < / detparam>
[0184] The detectors are arranged in each import lane, and detectors of the same phase can be used in combination, so that the detector data at least contains a lane number <laneno>.
[0185] Referring to the foregoing description of the carport, generally, near the diversion island of the intersection, towards the entrance direction of each lane, a detector is arranged on the stop line of the entrance lane to realize the function of electronic police, etc. Therefore, when the information uploaded by each device of the intersection includes the information uploaded by the detector, such as the IP address of the detector, the device identification of the detector, the intelligent transportation service platform to which the detector belongs, the sub-area to which the intersection to which the detector is arranged belongs, the intersection to which the detector is arranged, the signal machine corresponding to the intersection to which the detector is arranged, the lane serial number corresponding to the detector, the distance of the detector from the stop line, etc., the configurable elements matched out include the detector identification.
[0186] In some embodiments, in step S20, when the information uploaded by each device of the intersection includes the information uploaded by the detector, the configurable elements matched out include the detector identification; accordingly, in step S30, the following is included: matching out the detector identification and displaying the detector identification on the intersection channelization map configuration page; and configuring the channelization map of the intersection according to the operation of the user on the detector identification on the intersection channelization map configuration page.
[0187] As shown in Figure 2A , for any intersection, the configurable element with the image identification of "detector" in the left optional area is the detector configuration element. When the detector configuration element is operated, such as being selected and then clicked, a detector attribute configuration window as shown in Figure 2H is popped up. When each human-computer interaction control in the detector attribute configuration window is operated, the intelligent transportation service platform to which the detector belongs, the sub-area to which the intersection to which the detector is arranged belongs, the intersection to which the detector is arranged, the signal machine corresponding to the intersection to which the detector is arranged, the IP address of the detector, the device identification of the detector, etc. extracted according to the information uploaded by the detector are confirmed, and the detector instance as shown in Figure 2F can be configured and displayed near the island of the intersection, in the south-to-north direction south section, that is, the entrance direction, in the north-to-south direction north section, that is, the entrance direction, in the east-to-west direction east section, that is, the entrance direction, and in the west-to-east direction west section, that is, the entrance direction, which is a combination of multiple parallel lane boundary lines and lane stop lines perpendicular to the lane boundary lines.
[0188] Thus, according to the information uploaded by each device of the intersection, the matched configurable elements are determined by pre-processing, which includes detector identification, and the default values of each human-computer interaction control used to display in the detector attribute configuration window are extracted, which can reduce the workload of subsequent human-computer interaction for configuring detector instances and improve the efficiency of generating the channelization map.
[0189] After the above identification or instance is configured, the channelization map data corresponding to the intersection is updated by binding or saving operation, and is saved in the database for subsequent echo of the channelization map.
[0190] According to the foregoing description, to realize the green wave effect, coordinated control can be implemented at multiple upstream and downstream intersections on the road. At this time, there is at least one associated intersection at the current intersection. In some embodiments, in step S30, the configuration of the channelization map of the intersection further includes: according to the operation of the user on the associated intersection element in the intersection channelization map configuration page, configuring the associated intersection information of the intersection.
[0191] In some embodiments, as shown in Figure 2D For any intersection, the configurable element with the "associated intersection" text label in the left optional area is the associated intersection configuration element. Operating the associated intersection configuration element, such as clicking after selecting, the associated intersection attribute configuration window as shown in Figure 2I is popped up. Operating each human-computer interaction control in the associated intersection attribute configuration window, the intelligent transportation service platform to which the associated intersection belongs, the sub-area to which the associated intersection belongs, the identification or name of the associated intersection, the signal machine corresponding to the intersection set by the associated intersection, and the phase to be aligned when the associated intersection and the current intersection implement coordinated control, etc. can be configured to obtain the related information of the associated intersection JNC0001 displayed in the upper left area of the channelization map as shown in Figure 2J and is updated to the channelization map data.
[0192] Thus, according to the operation of the user on the associated intersection element in the intersection channelization map configuration page, the necessary information of the associated intersection is obtained, so that when the channelization map is echoed subsequently, the channelization map of other associated intersections associated with the current intersection can be directly echoed by clicking the "associated intersection" button to verify the effectiveness of the coordinated control between the upstream and downstream intersections.
[0193] In some embodiments, as shown in Figure 2D As shown, for any intersection, three blank configurable elements are displayed in the black background of the optional area on the right side, which are the associated intersection identification configuration elements. By operating these associated intersection identification configuration elements, the width and height of the text box for displaying the associated intersection information and the associated intersection information to be displayed can be configured respectively. For example, after selecting the associated intersection identification height configuration element, the height of the text box can be set by vertical dragging; after selecting the associated intersection identification width configuration element, the width of the text box can be set by horizontal dragging; and after selecting the associated intersection identification text configuration element, the text information in the text box can be set by text input. For example, for the intersection of Huanshidadao Road and Haigangdadao Road, the name of the associated intersection can be the intersection of Huanshidadao Road and Jiangmeilu Road.
[0194] In this way, according to the operation of the user on the associated intersection identification elements in the intersection channelization map configuration page, the width and height of the text box for displaying the associated intersection of the intersection and the text information can be configured, so that the text information can be displayed when the channelization map is echoed subsequently, and the generated channelization map is more friendly and easy to read.
[0195] In some embodiments, in step S30, the configuration of the channelization map of the intersection further includes: according to the operation of the user on the decoration element or the description element in the intersection channelization map configuration page, configuring the decoration element or the note element of the intersection.
[0196] In some embodiments, as shown in FIG. 6, the decoration element in the black background of the optional area on the left side is a white short bar identification, which can be used to configure the decoration elements such as the separation belt, the green belt or the isolation water horse between the lanes in the channelization map. By dragging the decoration element between the lanes, the decoration element can be adjusted to be green and the shape can be adjusted to generate a green belt decoration element; by dragging the decoration element between the lanes, the decoration element can also be adjusted to be black and the shape can be adjusted to generate an isolation water horse or a separation belt as a decoration element. Figure 2D In this way, according to the operation of the user on the decoration element in the intersection channelization map configuration page, the decoration element of the intersection is configured, so that the channelization mode of the intersection can be displayed more realistically.
[0197] In some embodiments, as shown in FIG. 6, the decoration element in the black background of the optional area on the left side is a white short bar identification, which can be used to configure the decoration elements such as the separation belt, the green belt or the isolation water horse between the lanes in the channelization map. By dragging the decoration element between the lanes, the decoration element can be adjusted to be green and the shape can be adjusted to generate a green belt decoration element; by dragging the decoration element between the lanes, the decoration element can also be adjusted to be black and the shape can be adjusted to generate an isolation water horse or a separation belt as a decoration element.
[0198] Figure 2D As shown, for any intersection, the note element in the black background of the optional area on the left shows the note element with a note identifier, which can be used to configure the note element in the channelization diagram for displaying the name of the road or intersection. Click the note element and drag it to the blank area of the area displaying the channelization diagram, enter the text, and the note element on the left shows Huanshidadao, which is used to indicate that the east-west direction road is Huanshidadao. Click the note element and drag it to the blank area of the area displaying the channelization diagram, enter the text, and the note element on the right shows Haigangdadao, which is used to indicate that the south-north direction road is Haigangdadao.
[0199] In this way, according to the operation of the user on the note element in the intersection channelization diagram configuration page, the note element of the intersection is configured, so that the channelization mode of the intersection can be more realistically displayed, and the generated channelization diagram is more friendly and easy to read.
[0200] In some embodiments, as shown in Figure 2D As shown, for any intersection, the color adjustment element in the black background of the optional area on the left also shows a gray block identifier, which can be used to configure the color of each element in the channelization diagram. After clicking any selected element, the color adjustment element is clicked, so that the color of the corresponding element when displayed in the channelization diagram can be conveniently modified, and details are not repeated. As shown in Figure 2F In the default, the background color of the displayed channelization diagram is black, and the text in the text box displaying the text information of the associated intersection is red; as shown in Figure 2J In the configuration, the background color of the displayed channelization diagram is khaki, and the text in the text box displaying the text information of the associated intersection is black.
[0201] In this way, according to the operation of the user on the color adjustment element in the intersection channelization diagram configuration page, the color of other elements of the intersection can be configured, so that the channelization mode of the intersection can be more realistically displayed, and the generated channelization diagram is more friendly and easy to read.
[0202] In some embodiments, as shown in Figure 2D As shown, for any intersection, the delete element in the black background of the optional area on the left also shows a delete identifier. For each element displayed in the channelization diagram, if it is no longer needed, any configurable element corresponding to the configuration element can be deleted by clicking the delete element.
[0203] In some embodiments, the configured channelization diagram is as shown in Figure 2K In this way, the intersection channelization diagram configuration page is configured for the channelization diagram of the intersection, each element is placed in the corresponding position of the channelization diagram, and after the binding operation, the real-time acquired and updated channelization diagram data is stored in the database in the background.
[0204] The elements or configurable elements in the configured channeling diagram can be drawn through the canvas, which is conducive to realizing what-you-see-is-what-you-get during the configuration process, and is also conducive to loading the channeling diagram data more quickly when the channeling diagram is echoed, and realizing visualization and dynamic display.
[0205] In some embodiments, the configured channeling diagram can also be echoed. When the channeling diagram is echoed, according to the phase locking instruction or the phase locking instruction sent by the received signal machine, the channeling diagram display interface can dynamically update the light state of the lamp.
