Description

Technical Field

[0001] The present invention relates to the field of intelligent transportation technology, and in particular to a low-latency intelligent transportation safety detection and early warning method and system. Background Art

[0002] Due to the obvious regional development characteristics in cities, urban public transportation congestion has become increasingly serious. Intelligent transportation technology has emerged as the times require. With the promotion and application of intelligent transportation technology, in order to facilitate more users to choose public transportation, it is necessary to design more complex bus routes and arrange bus stops more closely. At the same time, in order to facilitate users to understand the operation status of each bus route in real time through smart terminals and choose the most reasonable bus route, it is necessary to obtain the bus stop information at each bus stop in a more timely manner.

[0003] At present, many bus stops allow buses of multiple bus lines to stop at the same time, and passengers getting on and off the bus will take a lot of time, which makes traffic congestion very likely to occur near many bus stops. At the same time, many non-bus motor vehicles such as private cars and online taxis will also need to pass through bus stops when planning navigation routes. Since the navigation routes of many non-bus motor vehicles only need to pass through bus stops, they do not completely need to use bus lanes to make right turns. Many non-bus motor vehicles temporarily pass through bus stops to change lanes and overtake. For this reason, some people have proposed installing surveillance cameras at bus stops to cooperate with traffic management and prompt warnings. However, this solution requires the collection of video image data, and the hardware cost required for its data processing is high, and there is a high delay. Even if the relevant non-bus motor vehicles can be prompted, real-time performance is difficult to guarantee. Therefore, a low-latency intelligent traffic safety detection and warning solution is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a low-latency intelligent traffic safety detection and early warning method and system, which can realize safety detection and low-latency early warning of non-bus motor vehicles near bus stops without the need to collect and analyze video images of bus stops, thereby alleviating traffic congestion near bus stops.

[0005] The present invention solves the technical problem and adopts the following technical solution:

[0006] In one aspect, the present invention provides a low-latency intelligent traffic safety detection and early warning method, comprising the following steps:

[0007] The navigation server receives the client navigation route information of the non-public transport vehicle selected by the client and the vehicle navigation route information of the non-public transport vehicle, and screens out the client and the non-public transport vehicle to pass through the bus stop unit, and sends the screening result to the bus management platform;

[0008] Obtain information on the number of buses that will arrive at the same bus stop unit within a specified time through the bus management platform, screen out the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0009] The bus station unit forms a network after receiving the networking notification, and the networked bus station unit broadcasts the request instruction to the outside;

[0010] When the bus unit receives the request command, it determines that the signal strength of the request command reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply command to the bus stop unit;

[0011] When the bus stop unit receives a reply instruction, it determines that the number of reply instructions reaches a preset number, and then sends a recommended lane instruction to the clients and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and instructs the clients and non-bus motor vehicles that are about to pass through the bus stop to choose the non-bus lane to pass through the bus stop unit through the recommended lane instruction.

[0012] Furthermore, before the navigation server screens out the clients and non-bus vehicles to be passed through the bus stop unit, the process further includes:

[0013] The navigation server obtains the location information of the bus stop unit from the bus management platform.

[0014] Furthermore, when the location information of the bus stop unit changes, the changed location information of the bus stop is synchronized to the bus management platform.

[0015] Furthermore, when the navigation server screens out the client and the non-bus vehicle to be passed through the bus stop unit, the method further includes:

[0016] The navigation server calculates the time for the client and non-bus motor vehicles to pass through the bus station unit based on the client navigation route information and the vehicle navigation route information.

[0017] Furthermore, after the client and non-bus motor vehicles passing through the bus station select the non-bus lane to pass through the bus station unit, the client navigation route information and the vehicle navigation route information are updated and sent to the navigation server.

[0018] Furthermore, the obtaining of information on the number of buses that are expected to arrive at the same bus stop unit within a specified time through the public transportation management platform and screening out the bus stop units for networking means:

[0019] The bus management platform stores bus route information and bus schedule information of different routes. The bus route information and bus schedule information of different routes are used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time. When the number of buses that are expected to arrive at the same bus stop unit within the specified time reaches a specified number, the bus stop unit is used as a selected bus stop unit for networking.

[0020] Furthermore, the bus station unit forms a network after receiving the networking notification, and the networked bus station unit broadcasts a request instruction to the outside, which means:

[0021] After receiving the networking notification, the bus stop unit sequentially establishes a one-way wireless local area network between the current bus stop unit used for networking and the next bus stop unit used for networking according to the bus route direction;

[0022] After the current bus stop unit for networking broadcasts a request instruction, it notifies the next bus stop unit for networking to broadcast a request instruction through a one-way wireless local area network. The broadcast request instruction includes the unique identifier of the current bus stop unit for networking.

[0023] Furthermore, when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches a preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus stop unit, which means:

[0024] When the bus station unit of the network sends a broadcast request instruction, the unique identifier of each bus station unit used for networking is sent to the corresponding bus unit through the bus management platform;

[0025] When the bus unit receives the request instruction, if it is determined that the request instruction contains the unique identifier of the bus stop unit currently used for networking, it will determine whether the signal strength of the request instruction reaches the preset signal strength. When it reaches it, it will obtain the real-time location information of the bus unit and send a reply instruction to the bus stop unit currently used for networking, and the reply instruction contains the unique identifier of the current bus unit.

[0026] Furthermore, when the bus stop unit receives the reply instruction and determines that the number of reply instructions reaches a preset number, it sends a lane recommendation instruction to the client and non-bus vehicles that are about to pass through the bus stop within the communication range, and instructs the client and non-bus vehicles that are about to pass through the bus stop to choose the non-bus lane to pass through the bus stop unit through the lane recommendation instruction, which means:

[0027] The bus management platform pre-stores unique identifiers of all bus units;

[0028] After the bus station unit for networking is selected by the bus management platform, the unique identifiers of all bus units stored in advance are sent to the bus station unit for networking and stored in the form of an identifier storage list;

[0029] When the bus stop unit receives a reply instruction, if it is determined that the unique identifier of the bus unit contained in the reply instruction belongs to an identifier in the identifier storage list, it is determined whether the number of reply instructions reaches a preset number. If it reaches a preset number, a recommended lane instruction is sent to the client and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and the recommended lane instruction is used to instruct the client and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0030] On the other hand, the present invention also provides a low-latency intelligent traffic safety detection and warning system, which is applied to the low-latency intelligent traffic safety detection and warning method, comprising:

[0031] The navigation server is used to receive the navigation route information of the client selected by the client for using the non-public transport vehicle and the on-board navigation route information of the non-public transport vehicle, and screen out the clients and non-public transport vehicles to pass through the bus stop unit, and send the screening results to the bus management platform;

[0032] The public transportation management platform is used to obtain information on the number of buses that will arrive at the same bus stop unit within a specified time, screen out bus stop units for networking, send networking notifications to the bus stop units for networking, and synchronize the screening results to the bus stop units for networking after receiving them;

[0033] The bus stop unit is used to establish a network after receiving a networking notification. The networked bus stop unit broadcasts a request instruction and receives a reply instruction. After determining that the number of reply instructions reaches a preset number, the bus stop unit sends a lane recommendation instruction to the client and non-bus motor vehicles that are about to pass through the bus stop within the communication range. The recommended lane instruction instructs the client and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0034] The bus unit is used to, upon receiving a request instruction, determine that the signal strength of the request instruction reaches a preset signal strength, obtain the real-time location information of the bus unit, and send a reply instruction to the bus stop unit.

[0035] The beneficial effects of the present invention are as follows: through the above-mentioned low-latency intelligent traffic safety detection and early warning method and system, first, the navigation route information of the client selected by the client for non-public transport vehicles and the on-board navigation route information of non-public transport vehicles are received through the navigation server, and the clients and non-public transport vehicles to be passed through the bus stop unit are screened out, and the screening results are sent to the bus management platform; secondly, the bus management platform obtains the number of buses that are to arrive at the same bus stop unit within the specified time, screens out the bus stop units for networking, sends a networking notification to the bus stop units for networking, and after receiving the screening results, it is synchronized with the bus stop unit. Step to the bus stop unit for networking; then, the bus stop unit conducts networking after receiving the networking notification, and the networked bus stop unit broadcasts the request instruction to the outside; when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus stop unit; when the bus stop unit receives the reply instruction, it determines that the number of reply instructions reaches the preset number, and sends a recommended lane instruction to the clients and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and instructs the clients and non-bus motor vehicles that are about to pass through the bus stop to choose the non-bus lane to pass through the bus stop unit through the recommended lane instruction.

[0036] Therefore, the present invention establishes information exchange between the bus management platform and the navigation server, and in combination with the specific conditions of different bus stop units and the real-time conditions of the buses, instructs clients and non-bus motor vehicles to pass through the bus stop to choose non-bus lanes to pass through the bus stop units. There is no need to set up surveillance cameras in the bus stop, nor is there any need to collect and process video images from the surveillance cameras. Therefore, the present invention greatly reduces the delay when performing intelligent traffic safety detection and early warning. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 This is a flow chart of a low-latency intelligent traffic safety detection and early warning method in Example 1 of the present invention;

[0038] Figure 2 This is a schematic diagram of the composition structure of a low-latency intelligent traffic safety detection and warning system in Example 2 of the present invention. DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Example 1

[0041] This embodiment provides a low-latency intelligent traffic safety detection and warning method. Figure 1 , wherein the method comprises the following steps:

[0042] S1. Receive, through a navigation server, navigation route information of a client selected to use a non-public transport vehicle and in-vehicle navigation route information of a non-public transport vehicle, filter out clients and non-public transport vehicles to pass through a bus stop unit, and send the filtering result to a bus management platform;

[0043] S2. Obtain information on the number of buses that will arrive at the same bus stop unit within a specified time through the public transportation management platform, select the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0044] S3. The bus station unit forms a network after receiving the network formation notification, and the networked bus station unit broadcasts a request instruction to the outside;

[0045] S4. When the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus station unit;

[0046] S5. When the bus stop unit receives the reply instruction, it determines that the number of reply instructions reaches a preset number, and then sends a recommended lane instruction to the clients and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and instructs the clients and non-bus motor vehicles that are about to pass through the bus stop to choose the non-bus lane to pass through the bus stop unit through the recommended lane instruction.

[0047] In this embodiment, non-public transportation vehicles, such as private cars and online taxis, will most likely use on-board navigation software for navigation, and some will also use the user's smart terminal as a client and use the navigation software in the smart terminal for navigation. Therefore, when generating corresponding navigation routes, these non-public transportation vehicles may pass through bus stop units. In this case, many non-public transportation vehicles will temporarily occupy the bus lane on the side of the bus stop unit, which may be temporarily parked or temporarily used for overtaking. At present, due to the improvement of road monitoring mechanisms, most of them use the installation of surveillance cameras to complete the monitoring and early warning of these traffic violations. However, at this time, the surveillance camera needs to collect and process video images, which requires a long processing time, resulting in many non-public transportation vehicles unable to receive early warnings and prompts in time. Therefore, the present invention abandons the traditional high-latency image acquisition and processing solution.

[0048] Although some non-public transport vehicles use on-board navigation and some use clients for navigation, and the manufacturers of the navigation software used may not be the same, each manufacturer will use a navigation server to back up the navigation route information of the current manufacturer, so that the public transport management platform can more easily obtain the actual situation of non-public transport vehicles. However, due to the large number of non-public transport vehicles and clients, if each on-board navigation data or client navigation data is synchronized to the public transport management platform, it will cause huge data processing pressure and data storage pressure to the public transport management platform, and not all navigation routes will pass through the bus stop unit. Therefore, this embodiment needs to first screen out the clients and non-public transport vehicles that are to pass through the bus stop unit, and then synchronize them to the public transport management platform.

[0049] It should be noted that while the location information of bus stops is relatively fixed, it may change temporarily due to bus schedules or road maintenance. While the navigation server pre-stores the location information of many urban roads and related bus stops, this information may be delayed. When the location information of a bus stop changes, the public transportation management platform will typically synchronize this information first. Therefore, in this embodiment, before the navigation server selects clients and non-public transportation vehicles that will pass through the bus stop, the navigation server also obtains the location information of the bus stop from the public transportation management platform. Furthermore, when the location information of the bus stop changes, the changed location information of the bus stop is synchronized with the public transportation management platform.

[0050] Generally speaking, whether it is in-vehicle navigation or client navigation, after entering the departure and destination, the corresponding navigation route information will be obtained, and the approximate time information will also be obtained. Since many bus stop units have not yet been synchronously configured with special cameras for temporarily occupying bus lanes, in order to reach the destination as quickly as possible, many navigation routes may also have temporary occupation of bus lanes. In this embodiment, it is necessary to prompt these non-bus motor vehicles passing through the bus stop unit to drive through the regular motor vehicle lane. Therefore, after the non-bus motor vehicle passes through the bus stop unit, its estimated arrival time at the destination may change, and it is determined based on the regular motor vehicle lane selected by the non-bus motor vehicle at the bus stop unit. Therefore, it is necessary to know the time when the non-bus motor vehicle passes through the bus stop unit. Therefore, in this embodiment, when the navigation server screens out the client and non-bus motor vehicles to pass through the bus stop unit, it can also include: the navigation server calculates the time when the client and non-bus motor vehicle to pass through the bus stop unit based on the client navigation route information and the in-vehicle navigation route information.

[0051] At the same time, in order to achieve information synchronization between the navigation server and the on-board navigation software of non-public transport vehicles and the navigation software of the client as much as possible, in this embodiment, after the client and non-public transport vehicles passing through the bus station choose the non-public transport lane to pass through the bus station unit, the client navigation route information and the on-board navigation route information are updated and sent to the navigation server.

[0052] It should be noted that, since bus stop units are screened in this embodiment and serve as nodes for subsequent networking, in order to ensure that each bus stop unit in the network can efficiently send and receive commands as much as possible, the communication distance between adjacent nodes cannot be set too long. Therefore, in this embodiment, the bus stop unit screening process can refer to the following:

[0053] The bus management platform stores bus route information and bus schedule information of different routes. The bus route information and bus schedule information of different routes are used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time. When the number of buses that are expected to arrive at the same bus stop unit within the specified time reaches a specified number, the bus stop unit is used as a selected bus stop unit for networking.

[0054] In addition, the bus station unit forms a network after receiving the networking notification, and the networked bus station unit broadcasts a request instruction to the outside, which may refer to:

[0055] After receiving the networking notification, the bus stop unit sequentially establishes a one-way wireless local area network between the current bus stop unit used for networking and the next bus stop unit used for networking according to the bus route direction;

[0056] After the current bus stop unit for networking broadcasts a request instruction, it notifies the next bus stop unit for networking to broadcast a request instruction through a one-way wireless local area network. The broadcast request instruction includes the unique identifier of the current bus stop unit for networking.

[0057] Here, since there may be a load and numerous broadcast instructions in the space, if the broadcast request instruction is not uniquely identified and limited, there may be a risk of receiving erroneous instructions or being invaded by malicious instructions when sending and receiving instructions in this embodiment. Therefore, in this embodiment, the broadcast request instruction should include the unique identification of the bus stop unit currently used for networking, and the reply instruction should include the unique identification of the current bus unit.

[0058] Specifically, in this embodiment, when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches a preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus station unit, which may refer to:

[0059] When the bus station unit of the network sends a broadcast request instruction, the unique identifier of each bus station unit used for networking is sent to the corresponding bus unit through the bus management platform;

[0060] When the bus unit receives the request instruction, if it is determined that the request instruction contains the unique identifier of the bus stop unit currently used for networking, it will determine whether the signal strength of the request instruction reaches the preset signal strength. When it reaches it, it will obtain the real-time location information of the bus unit and send a reply instruction to the bus stop unit currently used for networking, and the reply instruction contains the unique identifier of the current bus unit.

[0061] It should be noted that in this embodiment, when the bus stop unit receives a reply instruction and determines that the number of reply instructions reaches a preset number, it sends a lane recommendation instruction to the client and non-bus vehicles that are about to pass through the bus stop within the communication range, and instructs the client and non-bus vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit through the lane recommendation instruction, which may refer to:

[0062] The bus management platform pre-stores unique identifiers of all bus units;

[0063] After the bus station unit for networking is selected by the bus management platform, the unique identifiers of all bus units stored in advance are sent to the bus station unit for networking and stored in the form of an identifier storage list;

[0064] When the bus stop unit receives a reply instruction, if it is determined that the unique identifier of the bus unit contained in the reply instruction belongs to an identifier in the identifier storage list, it is determined whether the number of reply instructions reaches a preset number. If it reaches a preset number, a recommended lane instruction is sent to the client and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and the recommended lane instruction is used to instruct the client and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0065] Example 2

[0066] Based on the first embodiment, this embodiment provides a low-latency intelligent traffic safety detection and warning system, the composition structure diagram of which is shown in FIG. Figure 2 , wherein the system comprises:

[0067] The navigation server is used to receive the navigation route information of the client selected by the client for using the non-public transport vehicle and the on-board navigation route information of the non-public transport vehicle, and screen out the clients and non-public transport vehicles to pass through the bus stop unit, and send the screening results to the bus management platform;

[0068] The public transportation management platform is used to obtain information on the number of buses that will arrive at the same bus stop unit within a specified time, screen out bus stop units for networking, send networking notifications to the bus stop units for networking, and synchronize the screening results to the bus stop units for networking after receiving them;

[0069] The bus stop unit is used to establish a network after receiving a networking notification. The networked bus stop unit broadcasts a request instruction and receives a reply instruction. After determining that the number of reply instructions reaches a preset number, the bus stop unit sends a lane recommendation instruction to the client and non-bus motor vehicles that are about to pass through the bus stop within the communication range. The recommended lane instruction instructs the client and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0070] The bus unit is used to, upon receiving a request instruction, determine that the signal strength of the request instruction reaches a preset signal strength, obtain the real-time location information of the bus unit, and send a reply instruction to the bus stop unit.

[0071] According to the description of the first embodiment, the application scenario and implementation principle of this embodiment are consistent with those of the first embodiment, and therefore will not be described in detail.
