On some special roads, vehicles on the two-way lanes need to take turns on the road; if the vehicles on the two-way lanes do not give way to each other and there is no traffic control, road congestion will occur at the intersection of two-way vehicles, causing traffic flow on the road to slow down or even stop. At present, traffic police are required to rush to the scene to coordinate and deal with such road congestion; however, special roads without traffic control are usually remote, and it is difficult for traffic police to arrive at the scene in time, resulting in low handling efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0041] Before introducing the embodiments of the present application, the relevant terms involved in the present application are first explained as follows:

[0042] (1) Telematics Service Provider (TSP) platform: refers to the service platform built by the party that provides automotive telematics services, which is used to achieve data interaction; specifically, it includes functions such as vehicle positioning, remote diagnosis, emergency calls, and navigation support.

[0043] (2) Telematic BOX (T-Box): A vehicle communication module used for communication between the vehicle and an external network (e.g., the vehicle and the TSP platform) to achieve data exchange between the vehicle and the external network.

[0044] (3) Head Unit (HUT): An important component of a vehicle, it is usually located in the center of the dashboard and is the central controller of the vehicle's infotainment system. The head unit integrates a variety of functions to provide convenience and entertainment experience for the driver and passengers.

[0045] (4) Digital Video Recorder (DVR): Also known as a driving recorder, it is an electronic device installed on a vehicle to record video images and sounds while the vehicle is driving. Its main purpose is to provide objective evidence in the event of a traffic accident, and it can also be used for daily driving safety monitoring.

[0046] Road congestion is a common problem in urban traffic management, affecting traffic efficiency and driving experience. On some special roads, vehicles on two-way lanes need to alternate on the road. For example, the types of road congestion include: roadblocks, road narrowing, broken-down vehicles occupying the road, narrow road corners, etc. Figure 1 , describes the special scenario where vehicles on two-way lanes need to alternate on the road section.

[0047] like Figure 1 As shown, Figure 1 A schematic diagram of a congestion type scenario of a road section provided in an embodiment of the present application. Specifically, Figure 1(a) is a schematic diagram of a roadblock passing scenario: the lane in one of the driving directions of the road section is occupied by obstacles such as fallen objects, roadblocks, and broken-down vehicles. At this time, vehicles in this driving direction need to bypass these obstacles by driving on the lane in the other driving direction in order to pass the road section.

[0048] Figure 1 (b) is a schematic diagram of another roadblock passing scenario: there are obstacles such as fallen objects, roadblocks, broken-down vehicles, etc. in one lane of the road section and part of the other lane. At this time, vehicles in both driving directions need to pass through the remaining available space of the road section to pass through the road section.

[0049] Figure 1 (c) is a schematic diagram of a scenario where the road surface is narrowed: due to road design or road construction, the width of a certain area on the road section is smaller than the width of other areas; vehicles in two driving directions on the road section need to pass alternately from the middle of the two lanes to pass the road section.

[0050] Figure 1 (d) in FIG. 1 is a schematic diagram of a narrow road curve. Narrow road curves are common in rural roads, old urban areas, etc. When a vehicle is driving on the road, the width of the curve is narrow, and vehicles traveling in both directions usually need to pass alternately to pass through the road.

[0051] When encountering the above scenarios, if the vehicles on the two-way lanes do not give way to each other and there is no traffic control, congestion will occur at the intersection of the two-way vehicles, causing the traffic flow on the road section to slow down or even stop. At present, for such road congestion, traffic police need to rush to the scene to coordinate and deal with it; however, special road sections without traffic control are usually remote, and it is difficult for traffic police to arrive at the scene in time, resulting in low processing efficiency. Therefore, how to timely regulate road congestion caused by alternating traffic to improve the efficiency of traffic control is a technical problem that needs to be solved urgently.

[0052] In view of this, the present application proposes a traffic dispatching method, device, service platform and system; the present application determines a target control parameter according to the road condition information in the first driving direction of the target road section; the vehicle passes through the target road section according to the target control parameter. Through the embodiments of the present application, the road section congestion caused by alternating traffic can be timely regulated to improve the efficiency of traffic regulation.

[0053] In order to illustrate the technical solution described in this application, a specific embodiment is used below to illustrate. First, a traffic dispatching system in an embodiment of this application is introduced.

[0054] Figure 2 It is a schematic diagram of a traffic dispatching system provided in an embodiment of the present application.

[0055] Exemplarily, the traffic dispatching system 200 includes: a service platform 210 and a plurality of vehicles 220 .

[0056] In actual application scenarios, the service platform 210 may be a TSP platform. For example, the service platform 210 may be a server or a computer or other device, and the present application embodiment does not impose any specific restrictions on this.

[0057] Exemplarily, the service platform 210 is respectively connected to the multiple vehicles 220 in communication, and then through the communication connection, data transmission between the service platform 210 and the multiple vehicles 220 is realized. For example, the vehicle 220 can be connected to the service platform 210 through a communication module (e.g., T-Box) in the vehicle 220 for wireless communication; the wireless communication connection can be a cellular network connection, a Wi-Fi (Wireless Fidelity) connection, a Bluetooth (BlueTooth, BT) connection, etc., and the embodiment of the present application does not specifically limit this.

[0058] Combine the following Figures 3 to 5 The traffic dispatching method provided in the embodiment of the present application is described in detail.

[0059] It should be understood that the embodiments of the present application do not specifically limit the execution subject of the traffic dispatch method, as long as the program that records the code of the traffic dispatch method of the embodiments of the present application can be run to communicate according to the traffic dispatch method of the embodiments of the present application. For example, the execution subject of the traffic dispatch method provided by the embodiments of the present application can be the service platform described in the above embodiments, or a traffic dispatch device applied to the service platform, such as a chip.

[0060] Figure 3 A flow chart of a traffic dispatching method provided in an embodiment of the present application.

[0061] S301. When it is detected that the target road section is in a congested state, obtain traffic information of the first driving direction of the target road section.

[0062] The traffic condition information is used to indicate the congestion level in the first driving direction.

[0063] For example, the target road section in a congested state can be used to indicate that there is a congestion on the road section, which causes vehicles on the two-way lanes to pass alternately on the road section; for details, please refer to Figure 1 Schematic diagram of the provided scenario.

[0064] For example, the target road section may include two lanes, and vehicles traveling on different lanes travel towards each other. In other words, there are two opposite driving directions on the target road section. For example, the target road section may include lane 1 and lane 2; vehicles traveling on lane 1 are in driving direction 1; vehicles traveling on lane 2 are in driving direction 2; driving direction 1 and driving direction 2 are opposite driving directions.

[0065] Exemplarily, the first driving direction may be any of two opposite driving directions of the target section. In the embodiment of the present application, the driving direction opposite to the first driving direction in the target section may be referred to as the second driving direction to facilitate the description of the first driving direction below.

[0066] It is not difficult to understand that when the target road section is in a congested state, since vehicles in the two driving directions need to pass alternately, both the first driving direction and the second driving direction will be in a congested state.

[0067] Exemplarily, the traffic condition information of the first driving direction may include: the length of the congested section in the first driving direction and the congestion type of the target section. Specifically, the length of the congested section in the first driving direction refers to the total length of the continuous congested section formed on the lane corresponding to the first driving direction due to excessive vehicles and reduced driving speed; the longer the congested section, the more serious the congestion. The congestion type of the target section may indicate the cause of the congestion in the target section; different congested sections cause different degrees of congestion. For a specific description of the congestion type, please refer to the above. Figure 1 , I will not go into details here.

[0068] Regarding how to obtain the road condition information of the first driving direction, please refer to the following embodiment, which will not be described in detail here.

[0069] S302. Determine target control parameters for a target vehicle in the first driving direction based on the road condition information in the first driving direction.

[0070] The target control parameters include the traffic indication signal and the target duration corresponding to the traffic indication signal.

[0071] As an example, the traffic instruction signal may be used to instruct the target vehicle in the first driving direction to pass; the target duration corresponding to the traffic instruction signal may be used to instruct the target vehicle to pass within the target duration.

[0072] It is not difficult to understand that when the traffic instruction signal indicates that the target vehicle in the first driving direction can pass within the target time, the vehicle in the second driving direction is prohibited from passing within the target time, so as to achieve the successful passage of the target vehicle in the first driving direction. Correspondingly, when the vehicle in the second driving direction passes, the target vehicle in the first driving direction is prohibited from passing, so as to achieve the alternating passage of vehicles in the two driving directions of the target road section, thereby alleviating congestion pressure.

[0073] As another example, the traffic instruction signal may also be used to indicate that target vehicles in the first driving direction are prohibited from passing; accordingly, the target duration corresponding to the traffic instruction signal may be used to indicate that target vehicles are prohibited from passing within the target duration.

[0074] It is not difficult to understand that when the traffic signal indicates that target vehicles in the first driving direction are prohibited from passing within the target time, vehicles in the second driving direction can pass within the target time, so as to achieve successful passage of vehicles in the second driving direction.

[0075] As another example, the traffic instruction signal may also include: traffic instruction signal A1 and traffic instruction signal A2, and priority information (for example, the priority of traffic instruction signal A1 is higher than the priority of traffic instruction signal A2). Accordingly, the target duration corresponding to the traffic instruction signal includes: target duration A1 corresponding to traffic instruction signal A1 and target duration A2 corresponding to traffic instruction signal A2. Among them, traffic instruction signal A1 and target duration A1 corresponding to traffic instruction signal A1 are used to indicate that the target vehicle can pass within the target duration A1. Traffic instruction signal A2 and target duration A2 corresponding to traffic instruction signal A2 are used to indicate that the target vehicle is prohibited from passing within the target duration A2.

[0076] Regarding how to determine the target control parameter based on the road condition information in the first driving direction, reference may be made to the following embodiments, which will not be described in detail here.

[0077] S303. Send target control parameters to the target vehicle, so that the target vehicle passes through the target road section according to the target control parameters.

[0078] Exemplarily, when the target vehicle receives the target control parameters, the traffic instruction signal and the target duration corresponding to the traffic instruction signal can be displayed on the screen of the on-board multimedia host of the target vehicle, so that the target vehicle can pass through the target section according to the target control parameters.

[0079] For example, the target vehicle may be behind a congested area in the target road segment to successfully pass through the target road segment.

[0080] As an example, take the traffic instruction signal to indicate vehicle passage as an example: send the target control parameter to the target vehicle; accordingly, after the target duration has passed, send the target control parameter to the vehicle in the second driving direction. If the target vehicle receives the target control parameter, it can pass within the target duration; after receiving the target duration of the traffic instruction signal, if the target vehicle has not passed the target section, it is prohibited from passing; at this time, the vehicle in the second driving direction receives the target control parameter and passes within the target duration. In other words, if the vehicle receives the traffic instruction signal, the vehicle passes within the target duration; if the vehicle does not receive the traffic instruction signal, the vehicle is prohibited from passing.

[0081] As another example, take the case where a traffic instruction signal indicates that vehicles are prohibited from passing: a target control parameter is sent to the target vehicle; accordingly, the target control parameter can be sent to vehicles in the second driving direction after the target duration has passed. When the target vehicle receives the target control parameter, it can be prohibited from passing within the target duration, and vehicles in the second driving direction can pass; after receiving the target duration of the traffic instruction signal, the target vehicle can pass; at this time, vehicles in the second driving direction are prohibited from passing. In other words, if the vehicle receives a traffic instruction signal, the vehicle is prohibited from passing within the target duration; if the vehicle does not receive a traffic instruction signal, the vehicle can pass.

[0082] It can be understood that, from the above two examples, by having the traffic instruction signal indicate only one of passage or no passage, vehicles in two driving directions of the target road section can pass alternately, thereby alleviating the pressure of road congestion.

[0083] Of course, as another example, the traffic instruction signal can also be used to indicate vehicle passage and / or vehicle prohibition of passage. At this time, if a traffic instruction signal indicating vehicle passage is sent to the target vehicle, a traffic instruction signal indicating vehicle prohibition of passage can be sent to the vehicle in the second driving direction at the same time. Alternatively, if control parameter 1 is sent to the target vehicle (control parameter 1 includes traffic instruction signal 1 indicating vehicle passage and target duration 1 corresponding to traffic instruction signal 1, traffic instruction signal 2 indicating vehicle prohibition of passage and target duration 2 corresponding to traffic instruction signal 2, and priority information 1 (the priority of traffic instruction signal 1 is higher than the priority of traffic instruction signal 2)), control parameter 2 can be sent to the vehicle in the second driving direction at the same time (control parameter 2 includes traffic instruction signal 2 indicating vehicle prohibition of passage and target duration 1 corresponding to traffic instruction signal 2, traffic instruction signal 1 indicating vehicle passage and target duration 2 corresponding to traffic instruction signal 1, and priority information 2 (the priority of traffic instruction signal 2 is higher than the priority of traffic instruction signal 1)). When the target vehicle receives control parameter 1 (target control parameter) and the vehicles in the second driving direction receive control parameter 2, the target vehicle passes within the target time length 1, while vehicles in the second driving direction are prohibited from passing within the target time length 1; after passing the target time length 1, the target vehicle is prohibited from passing within the target time length 2, while vehicles in the second driving direction pass within the target time length 2.

[0084] As an example, the traffic instruction signal may be used to instruct the target vehicle in the first driving direction to pass; the target duration corresponding to the traffic instruction signal may be used to instruct the target vehicle to pass within the target duration.

[0085] It is not difficult to understand that when the traffic signal indicates that the target vehicle in the first driving direction can pass within the target time, the vehicles in the second driving direction are prohibited from passing within the target time to enable the target vehicle in the first driving direction to pass successfully.

[0086] As another example, the traffic instruction signal may also be used to indicate that target vehicles in the first driving direction are prohibited from passing; accordingly, the target duration corresponding to the traffic instruction signal may be used to indicate that target vehicles are prohibited from passing within the target duration.

[0087] It is not difficult to understand that when the traffic signal indicates that target vehicles in the first driving direction are prohibited from passing within the target time, vehicles in the second driving direction can pass within the target time, so as to achieve successful passage of vehicles in the second driving direction.

[0088] As another example, the traffic instruction signal may also include: traffic instruction signal A1 and traffic instruction signal A2; accordingly, the target duration corresponding to the traffic instruction signal includes: target duration A1 corresponding to traffic instruction signal A1 and target duration A2 corresponding to traffic instruction signal A2. Traffic instruction signal A1 and target duration A1 corresponding to traffic instruction signal A1 are used to indicate that the target vehicle can pass within target duration A1. Traffic instruction signal A2 and target duration A2 corresponding to traffic instruction signal A2 are used to indicate that the target vehicle is prohibited from passing within target duration A2.

[0089] The following is an exemplary description of the display method of traffic signs on the screen of the in-vehicle multimedia host.

[0090] As an example, the display mode of the traffic instruction signal on the screen of the vehicle multimedia host may be displayed in a graphical manner, and the graphic may have a certain shape (e.g., circle, triangle, etc.) and color (e.g., green, red, etc.); accordingly, the target duration is displayed in a timing manner. For example, if the traffic instruction signal indicates that the target vehicle in the first driving direction passes, the traffic instruction signal may be displayed as a green circular graphic on the screen of the vehicle multimedia host. For another example, if the traffic instruction signal indicates that the target vehicle in the first driving direction is prohibited from passing, the traffic instruction signal may be displayed as a red circular graphic on the screen of the vehicle multimedia host. In other words, when the traffic instruction signal is displayed in a graphical manner, it may be displayed in the form of a virtual traffic light.

[0091] As another example, the traffic instruction signal may be displayed on the screen of the vehicle-mounted multimedia host in the form of text or numbers; accordingly, the target duration is displayed in the form of timing. For example, if the traffic instruction signal indicates that the target vehicle in the first driving direction may pass, the traffic instruction signal may be displayed on the screen of the vehicle-mounted multimedia host in the form of text "Please pass"; or, it may be displayed in the form of "1"; wherein "1" indicates that it is allowed to pass. For another example, if the traffic instruction signal indicates that the target vehicle in the first driving direction is prohibited from passing, the traffic instruction signal may be displayed on the screen of the vehicle-mounted multimedia host in the form of text "No passage"; or, it may be displayed in the form of "0"; wherein "0" indicates that it is prohibited to pass.

[0092] Of course, the traffic signal can be displayed on the screen of the vehicle multimedia host in a combination of graphics and text. Figure 4 As shown, Figure 4 A schematic diagram of a traffic signal provided in an embodiment of the present application. Figure 4As shown in (a) of FIG. 1 , if the traffic signal indicates that the target vehicle in the first driving direction is allowed to pass, the traffic signal can be displayed on the screen of the vehicle multimedia host in the form of a circular graphic of color 1 and the text "Please pass", and the current remaining time is "4 minutes and 49 seconds". Figure 4 As shown in (b) in the figure, if the traffic signal indicates that the target vehicle in the first driving direction is prohibited from passing, the traffic signal can be displayed on the screen of the vehicle-mounted multimedia host in combination with a circular graphic of color 2 and the text "No Passing", and the current remaining time is "4 minutes and 47 seconds".

[0093] Optionally, when the target vehicle leaves the target section or leaves the congested area of ​​the target section, or when the speed of the target vehicle reaches a certain speed (for example, 30 km / h), the traffic sign and target duration can be cancelled on the screen of the vehicle-mounted multimedia host.

[0094] In an embodiment of the present application, when it is detected that the target road section is in a congested state, the road condition information of the first driving direction is obtained; in this way, the congestion degree of the first driving direction can be timely understood through the road condition information; then, based on the road condition information of the first driving direction, the target control parameters for the target vehicle in the first driving direction are quickly determined; the target control parameters are sent to the target vehicle so that the target vehicle passes through the target road section according to the target control parameters, thereby effectively regulated the traffic congestion in the first driving direction; based on this, compared with the method in the related art that requires notifying the traffic police to rush to the scene for coordination and processing, the embodiment of the present application can timely regulate the road section congestion caused by alternating traffic, so as to improve the efficiency of traffic regulation.

[0095] In a possible embodiment of the present application, the road condition information includes: the length of the congested section and the congestion type of the target section; the above S302 includes: determining the traffic indication signal and the initial duration corresponding to the traffic indication signal according to the length of the congested section; adjusting the initial duration according to the congestion type of the target section to obtain the target duration.

[0096] For example, the length of the congested road section can be measured by the distance between the congestion starting point (e.g., the first vehicle position) and the congestion end point (e.g., the last vehicle position); since the longer the congested road section is, the more serious the congestion in the first driving direction is, and the more target vehicles are on the congested road section, more time is needed to regulate the congestion of the road section in the first driving direction. In other words, the length of the congested road section is positively correlated with the target time corresponding to the traffic indication signal.

[0097] For example, since the congestion type of the target road section can indicate the cause of the road section congestion on the target road section, different congestion types cause different congestion levels in the first driving direction, and therefore the durations for regulating the road section congestion in the first driving direction are also different. In other words, the congestion type of the target road section is correlated with the target duration corresponding to the traffic indication signal.

[0098] In addition, the same type of congestion may cause different levels of congestion in different driving directions.

[0099] In order to better represent the impact of the target road segment congestion type on the initial duration of the road segment congestion in the first driving direction, the embodiment of the present application can adjust the initial duration by means of a congestion coefficient. In other words, the target duration can be the product of the initial duration and the congestion coefficient. Figure 1 The target road section can be divided into the congestion type of one-side roadblock, the congestion type of double-side roadblock, the congestion type of road narrowing, the congestion type of faulty vehicles occupying the road and the congestion type of narrow road turning.

[0100] refer to Figure 1 The congestion type of one-sided roadblock shown in (a) is: due to the existence of an obstacle on the lane corresponding to one driving direction (for example, driving direction 1), vehicles in this driving direction need to pass through the lane corresponding to another driving direction (for example, driving direction 2); therefore, the congestion coefficient in driving direction 1 can be 1.5; the congestion coefficient in driving direction 2 can be 1.

[0101] refer to Figure 1 The congestion type of double-sided roadblock traffic shown in (b) is: due to the presence of obstacles in one lane of the road section and part of the other lane, vehicles in both driving directions need to pass through the remaining available space of the target road section; therefore, the congestion coefficient in both driving directions can be 1.5.

[0102] refer to Figure 1 The congestion type of road narrowing shown in (c) is: due to the narrowing of an area on the target road section, vehicles in the two driving directions need to pass alternately from the middle of the two lanes; therefore, the congestion coefficient in the two driving directions can be 1.2.

[0103] refer to Figure 1 The congestion type of narrow road turning shown in (d) is: since the width of the turning part of the target road section is narrow, vehicles in two driving directions need to pass alternately at the turning part of the target road section; therefore, the congestion coefficients in the two driving directions can be 1.1.

[0104] Of course, the above congestion coefficient is only exemplified in the embodiment of the present application, and the specific size of the congestion coefficient can also be adjusted according to actual conditions.

[0105] The following is an exemplary description of a method for determining a target duration corresponding to a traffic signal.

[0106] As an example, when the length of the congested road section in the first driving direction is less than or equal to 100 meters (for example, the length of the congested road section is 100 meters), it can be determined that the traffic instruction signal sent to the target vehicle indicates passage, and the initial duration corresponding to the traffic instruction signal is 70 seconds. In the case where the congestion type of the target road section is single-sided roadblock passage, if the obstacle is located in the first driving direction, the initial duration is adjusted to obtain a target duration of 105 (70×1.5=105) seconds; if the obstacle is located in the second driving direction, the initial duration is adjusted to obtain a target duration of 70 (70×1=70) seconds. In the case where the congestion type of the target road section is double-sided roadblock passage, the initial duration is adjusted to obtain a target duration of 105 (70×1.5=105) seconds. In the case where the congestion type of the target road section is road narrowing, the initial duration is adjusted to obtain a target duration of 84 (70×1.2=84) seconds. When the congestion type of the target road section is narrow road curve, the initial duration is adjusted to obtain a target duration of 77 (70×1.1=77) seconds.

[0107] As another example, when the length of the congested section in the first driving direction is greater than 100 meters and less than or equal to 500 meters (for example, the length of the congested section is 400 meters), it can be determined that the traffic instruction signal sent to the target vehicle indicates passage, and the initial duration corresponding to the traffic instruction signal is approximately 285 seconds. In the case where the congestion type of the target section is single-sided roadblock passage, if the obstacle is located in the first driving direction, the initial duration is adjusted to obtain a target duration of 285 (285×1.5=427.5) seconds; if the obstacle is located in the second driving direction, the initial duration is adjusted to obtain a target duration of 285 (285×1=285) seconds. In the case where the congestion type of the target section is double-sided roadblock passage, the initial duration is adjusted to obtain a target duration of 285 (285×1.5=427.5) seconds. When the congestion type of the target road section is road narrowing, the initial duration is adjusted to obtain a target duration of 342 (285×1.2=342) seconds. When the congestion type of the target road section is narrow road cornering, the initial duration is adjusted to obtain a target duration of 313.5 (285×1.1=313.5) seconds.

[0108] As another example, when the length of the congested road section in the first driving direction is greater than 500 meters and less than or equal to 1000 meters (for example, the length of the congested road section is 750 meters), it can be determined that the traffic instruction signal sent to the target vehicle indicates passage, and the initial duration corresponding to the traffic instruction signal is 536 seconds. When the congestion type of the target road section is single-sided roadblock passage, if the obstacle is located in the first driving direction, the initial duration is adjusted to obtain a target duration of 535 (535×1.5=802.5) seconds; if the obstacle is located in the second driving direction, the initial duration is adjusted to obtain a target duration of 535 (535×1=535) seconds. When the congestion type of the target road section is double-sided roadblock passage, the initial duration is adjusted to obtain a target duration of 802.5 (535×1.5=802.5) seconds. When the congestion type of the target road section is road narrowing, the initial duration is adjusted to obtain a target duration of 642 (535×1.2=642) seconds. When the congestion type of the target road section is narrow road curve, the initial duration is adjusted to obtain a target duration of 588.5 (535×1.1=588.5) seconds.

[0109] As another example, when the length of the congested road section in the first driving direction is greater than 1000 meters (for example, 1200 meters), it can be determined that the traffic instruction signal sent to the target vehicle indicates passage, and the initial duration corresponding to the traffic instruction signal is 855 seconds. When the congestion type of the target road section is single-sided roadblock passage, if the obstacle is located in the first driving direction, the initial duration is adjusted to obtain a target duration of 1282.5 (855×1.5=1282.5) seconds; if the obstacle is located in the second driving direction, the initial duration is adjusted to obtain a target duration of 855 (855×1=855) seconds. When the congestion type of the target road section is double-sided roadblock passage, the initial duration is adjusted to obtain a target duration of 1282.5 (855×1.5=1282.5) seconds. When the congestion type of the target road section is road narrowing, the initial duration is adjusted to obtain a target duration of 1026 (855×1.2=1026) seconds. When the congestion type of the target road section is narrow road curve, the initial duration is adjusted to obtain a target duration of 940.5 (855×1.1=940.5) seconds.

[0110] Regarding how to determine the length of the congested road section and how to determine the initial duration, please refer to the following embodiments, which will not be described in detail here.

[0111] In an embodiment of the present application, since the target duration can be determined by combining the length of the congested road section and the congestion type, the target duration can be determined by referring to the congestion level of the target road section, thereby improving the reliability of regulating traffic congestion in the first driving direction.

[0112] In a possible embodiment of the present application, the initial duration is determined according to the length of the congested road section, including: obtaining the current vehicle speed, the preset vehicle distance and the preset vehicle length; determining the unit duration of a target vehicle's passage according to the current vehicle speed, the preset vehicle distance and the preset vehicle length; determining the number of target vehicles according to the length of the congested road section, the preset vehicle distance and the preset vehicle length; determining the initial duration according to the number of all target vehicles and the unit duration.

[0113] The current vehicle speed is used to indicate the speed of the target vehicle when traveling on the target road section.

[0114] For example, when a vehicle is traveling on a road section in a congested state, the vehicle usually travels at a relatively slow speed. The target vehicle can determine the current vehicle speed through a speed sensor on the target vehicle.

[0115] Exemplarily, the preset vehicle distance and the preset vehicle length may be values ​​preconfigured by the service platform, or may be manually set values, and the embodiments of the present application do not impose any specific restrictions on this.

[0116] The following example takes the current vehicle speed of 5 km / h (1.4 m / s), the preset vehicle length of 3 m, and the preset vehicle distance of 4 m as an example: Based on the current vehicle speed, the preset vehicle distance, and the preset vehicle length, the unit time length of a target vehicle passing through is determined to be 5 seconds. Specifically: unit time length = (preset vehicle length + preset vehicle distance) / current vehicle speed = 7 / 1.4 = 5 seconds.

[0117] As an example, when the length of the congested road section in the first driving direction is less than or equal to 100 meters, the number of target vehicles can be determined based on the length of the congested road section, the preset vehicle distance and the preset vehicle length. For example: the number of target vehicles = the length of the congested road section / (preset vehicle distance + preset vehicle length) ≈ 14 vehicles. Then, the initial duration is determined based on the number of target vehicles and the unit duration. For example: the initial duration = the number of target vehicles × the unit duration = 70 seconds.

[0118] As another example, when the length of the congested road section in the first driving direction is greater than 100 meters and less than or equal to 500 meters (for example, the length of the congested road section is 400 meters), the number of target vehicles can be determined based on the length of the congested road section, the preset vehicle distance and the preset vehicle length. For example: the number of target vehicles = the length of the congested road section / (preset vehicle distance + preset vehicle length) ≈ 57 vehicles. Then, the initial duration is determined based on the number of target vehicles and the unit duration. For example: the initial duration = the number of target vehicles × the unit duration = 285 seconds.

[0119] As another example, when the length of the congested road section in the first driving direction is greater than 500 meters and less than or equal to 1000 meters (for example, the length of the congested road section is 750 meters), the number of target vehicles can be determined based on the length of the congested road section, the preset vehicle distance and the preset vehicle length. For example: the number of target vehicles = the length of the congested road section / (preset vehicle distance + preset vehicle length) ≈ 107 vehicles. Then, the initial duration is determined based on the number of target vehicles and the unit duration. For example: the initial duration = the number of target vehicles × the unit duration of 535 seconds.

[0120] As another example, when the length of the congested road section in the first driving direction is greater than 1000 meters (for example, 1200 meters), the number of target vehicles can be determined based on the length of the congested road section, the preset vehicle distance and the preset vehicle length. For example: the number of target vehicles = the length of the congested road section / (preset vehicle distance + preset vehicle length) ≈ 171 vehicles. Then, the initial duration is determined based on the number of target vehicles and the unit duration. For example: the initial duration = the number of target vehicles × the unit duration 855 seconds.

[0121] In an embodiment of the present application, the initial duration is determined by the current vehicle speed, the preset vehicle distance and the preset vehicle length in combination with the length of the congested road section, which can improve the reliability of regulating the traffic congestion in the first driving direction.

[0122] In a possible embodiment of the present application, the above S301 includes the following two methods:

[0123] Method 1: Obtain navigation information of a target vehicle; determine the length of a congested road section and the congestion type of the target road section based on the navigation information.

[0124] Exemplarily, the navigation information of the target vehicle can be used to collect the traffic information of the target road section where the current target vehicle is traveling; for example, when the navigation of the target vehicle is turned on, the navigation can collect real-time traffic data from different sources (for example, traffic monitoring cameras, ground sensing coils, vehicle detectors, etc.); or collect feedback information from other users (for example, information such as traffic congestion, accidents or construction), etc., to monitor the traffic information of the road section. Furthermore, the embodiment of the present application can determine the length of the congested road section and the congestion type of the target road section through the navigation information.

[0125] Method 2: Obtain the road condition data of the first driving direction; obtain the length of the congested section according to the distance between the first vehicle position and the last vehicle position in the vehicle position; obtain the congestion type of the target section according to the image of the target section.

[0126] The road condition data includes the vehicle position of the target vehicle and the image of the target road section. For example, the position of the target vehicle (eg, the position of the first vehicle and the position of the last vehicle) can be determined by using positioning technology (eg, the global positioning system (GPS)).

[0127] For example, the image of the target road section may be acquired through the image or video data captured by the DVR of each target vehicle.

[0128] Exemplarily, the first vehicle may be a vehicle at the beginning of the congested section of the target section; and the last vehicle may be a vehicle at the end of the congested section of the target section.

[0129] Exemplarily, the distance between the position of the first vehicle and the position of the last vehicle may be the straight-line distance between the first vehicle and the last vehicle, or the distance between the first vehicle and the last vehicle on the actual driving path, and the embodiment of the present application does not impose any specific limitation on this.

[0130] For example, the image of the target section can be used to identify the type of the current target section, the condition of the lanes on the target section (for example, whether there are obstacles on the lanes), and the density of vehicles on the congested section of the current target section, thereby obtaining the congestion type of the target section.

[0131] In an embodiment of the present application, by determining the length of the congested road section and the type of congestion through navigation information or road condition data, it is possible to ensure that road condition information is obtained, thereby improving the reliability of regulating traffic congestion in the first driving direction.

[0132] In a possible embodiment of the present application, the method provided in the embodiment of the present application also includes: obtaining the moving distance of the target vehicle; if there are a preset number of first vehicles, determining that the target road section is in a congested state.

[0133] The moving distance of the first vehicle is less than a preset distance within a preset time period.

[0134] Exemplarily, the preset quantity, preset duration, and preset distance may be values ​​preconfigured by the service platform or the vehicle, or may be manually set values, and the embodiments of the present application do not impose any specific restrictions on this.

[0135] For example, the positioning module in the first vehicle can determine whether the moving distance of the first vehicle in a preset time (e.g., 5 minutes) is less than a preset distance (e.g., 500 meters). If the number of first vehicles less than the preset distance is greater than or equal to a preset number (e.g., 10 vehicles), it is determined that the preset condition 1 is met.

[0136] Optionally, when it is determined that there are a preset number of first vehicles, it can also be determined whether there is a target object on the target road section. If there is no target object on the target road section, it can be further determined that the target road section is in a congested state. The target object is used to perform traffic control on the congested road section.

[0137] Exemplarily, the target objects may generally include traffic lights, traffic police and other objects.

[0138] Exemplarily, it is possible to determine whether the target object exists on the target road section through the navigation information of the first vehicle. For example, the navigation information may include identification information of the current map, and the identification information may include the identification of the target object. If the identification information of the current map does not include the identification of the target object, it is determined that the target object does not exist on the target road section.

[0139] In an embodiment of the present application, by detecting whether the first driving direction of the target road section meets the preset conditions, it is possible to quickly determine whether the target road section is in a congested state, and then obtain the road condition information of the first driving direction in a timely manner.

[0140] In a possible embodiment of the present application, the method provided in the embodiment of the present application also includes: sending request information to the target platform; then the above S302 includes: upon receiving the indication information sent by the target platform, determining the target control parameters according to the road condition information of the first driving direction.

[0141] The request information is used to request traffic control for vehicles on the target road section; and the instruction information is used to instruct traffic control for vehicles on the target road section.

[0142] Exemplarily, the target platform may be a traffic control platform.

[0143] Exemplarily, the service platform may send a request message to the traffic control platform to request the service platform to perform traffic control on the target road section. Upon receiving the instruction message sent by the traffic control platform, the service platform may determine that the traffic control platform allows the service platform to perform traffic control on the target road section. For example, upon receiving the request message, the traffic control platform may determine the situation of the target road section; if the traffic control platform recognizes that the target road section is in a congested state and can perform traffic control on the target road section through remote control, the traffic control platform may send an instruction message to the service platform.

[0144] Optionally, the traffic control platform may also determine whether it is necessary to perform traffic control on the target road section by remote control when receiving the request information. If it is determined that the target road section is not to be remotely controlled, offline control may be performed.

[0145] For example, when the service platform performs traffic control on the target road section by remote control, the traffic control platform can also supervise the target vehicle to improve the efficiency of traffic control.

[0146] For example, when the service platform performs traffic control on the target road section through remote control, the traffic control platform can also establish a communication connection with the target vehicle (e.g., the first vehicle) in the first driving direction to guide the first vehicle to pass through the target road section.

[0147] In the embodiments of the present application, by using request information and indication information, the reliability of the service platform for traffic control can be improved, and the efficiency of traffic control can be further improved.

[0148] As a possible implementation method, S302 includes: sending road condition information of a first driving direction to a target platform; and receiving a target control parameter sent from the target platform.

[0149] Exemplarily, the service platform may send the road condition information of the first driving direction to the traffic control platform, and the traffic control platform determines and sends the target control parameters to the service platform, so that the service platform determines the target control parameters.

[0150] In the embodiment of the present application, the reliability of the target control parameters can be further improved by determining and issuing the target control parameters through the traffic control platform.

[0151] like Figure 5 As shown, Figure 5 Taking the traffic control method as an example, the specific implementation steps of a traffic control method provided in the embodiment of the present application are described as follows:

[0152] For example, the execution subject of S501 to S503 and S516 below is the HUT in the target vehicle; the execution subject of S504 to S505 is the vehicle hardware in the target vehicle; the execution subject of S506 to S507 and S512 to S515 is the TSP platform; the execution subject of S508 to S511 is the traffic control platform.

[0153] Exemplarily, the target vehicle is a vehicle traveling in a first driving direction of the target road section.

[0154] S501. Start navigation and positioning.

[0155] S502: Determine whether there is a traffic light nearby. If yes, execute S503.

[0156] S503: Determine whether the average speed is less than the preset speed. If so, execute S504.

[0157] S504. Turn on the DVR to collect video data.

[0158] S505. Send video data to the TSP platform.

[0159] S506. Determine, based on the video data, whether the target road section is in a congested state.

[0160] S507. Send video data to the traffic attention platform.

[0161] S508. Determine whether remote control is required. If yes, execute S509; if no, execute S511.

[0162] S509. Determine the traffic signal and target traffic duration based on the video data.

[0163] S510. Send a passing signal and a target passing time to the target vehicle.

[0164] S511. Send instruction information to the TSP platform.

[0165] S512. Obtain navigation information from a target vehicle (eg, HUT).

[0166] S513. Determine the length of the congested section and the congestion type of the target section according to the navigation information.

[0167] S514. Determine the traffic signal and target traffic time according to the length of the congested section and the congestion type of the target section.

[0168] S515. Send a passing signal and target passing time to the target vehicle.

[0169] It needs to be explained that when the traffic control platform participates in remote control, S509 to S510 can be executed; when the traffic control platform does not participate in remote control, S511 to S515 can be executed.

[0170] S516. Display the traffic signal and target traffic time.

[0171] Optionally, after S516, the method provided in the embodiment of the present application further includes: the vehicle hardware of the target vehicle continuously turns on the DVR to collect current video data. The vehicle hardware of the target vehicle sends the current video data to the TSP platform and the traffic control platform. The TSP platform and the traffic control platform supervise the target vehicle when receiving the current video data.

[0172] Optionally, when the TSP platform determines the length of the congested road section and the congestion type of the target road section, if the target vehicle does not turn on navigation, the TSP platform obtains the vehicle position of the target vehicle and the image of the target road section. The TSP platform obtains the length of the congested road section based on the distance between the first vehicle position and the last vehicle position in the vehicle position. The TSP platform obtains the congestion type of the target road section based on the image of the target road section.

[0173] For detailed description of S501 to S516, please refer to Figure 3 to Figure 4 The relevant descriptions will not be repeated here.

[0174] In an embodiment of the present application, navigation positioning is turned on by the target vehicle, and when there is no traffic light nearby and the average speed is less than a preset speed, the DVR is turned on to collect video data and send the video data to the TSP platform; in this way, the TSP platform can promptly understand whether the current target road section is in a congested state and conduct traffic regulation in a timely manner; the TSP platform sends video data to the traffic control platform, and quickly determines the traffic indication signal and the target travel time by receiving information from the traffic control platform or by obtaining navigation information, and then determines the traffic indication signal and the target travel time; thereafter, the target control parameters are sent to the target vehicle so that the target vehicle can display the traffic indication signal and the target travel time to pass through the target road section, thereby effectively regulating the traffic congestion in the first driving direction; based on this, the embodiment of the present application can promptly regulate the road section congestion caused by alternating traffic to improve the efficiency of traffic regulation.

[0178] For example, Figure 6 As shown, the device comprises:
