In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Firstly, an application scenario of the traffic intersection management method is introduced, as shown in fig. 1, when a terminal 10 is arranged at a traffic intersection, when a vehicle 20 enters a preset map range, the terminal 10 obtains driving information and parameter information of the vehicle 20, creates a simulated motion track of the vehicle 20 in the preset map according to the driving information of the vehicle 20, then obtains a collision point of the vehicle 20 in the preset map according to the simulated motion track, the driving information and the parameter information of the vehicle 20, and finally sends alarm information to the vehicle 20 which is likely to collide in the preset map, so that a driver is reminded to take measures to avoid collision, and the safety of the vehicle 20 passing through the traffic intersection is improved.
Fig. 2 is a schematic flow chart of a traffic intersection management method provided in an embodiment of the present application, and by way of example and not limitation, the method may include the following steps:
s101, acquiring the running information and the parameter information of all vehicles in a preset map range.
Specifically, the preset map is designed according to the actual conditions of the traffic intersection, the size of the range of the preset map can be designed according to the actual requirements, and the preset map can set the range on the basis of the existing maps (the existing maps such as a Baidu map and an Tencent map) to form the preset map. The driving information of the vehicle at least comprises lane information, speed information and steering information of the vehicle, the lane information, the speed information and the steering information can be collected through various sensors on the vehicle, and then a controller on the vehicle sends the collected lane information, speed information and steering information to a terminal device for managing a traffic intersection; the parameter information of the vehicle comprises the size information (the length, the width and the like) of the vehicle, the controller on the vehicle sends the size information of the vehicle to the terminal equipment for managing the traffic intersection, and the terminal equipment finishes the acquisition of the vehicle running information and the parameter information in turn.
For example, the method for acquiring the driving information may include:
and S1011, acquiring behavior information of a driver on the vehicle.
Specifically, when the vehicle turns, the driver usually observes the rearview mirror and the direction of the vehicle; when the vehicle is traveling straight, the driver usually observes the directions of both sides. An image acquisition device (such as a high-definition camera) on the vehicle acquires behavior information of a driver, and a controller on the vehicle transmits the acquired behavior information to the terminal equipment.
And S1012, determining the driving direction of the vehicle according to the behavior information.
Specifically, the behavior information of the driver collected in step S1011 can be used to analyze and determine whether the driver has an intention to turn when passing through the traffic intersection, so as to simulate the movement track of the vehicle in the preset map.
S1013, when the traveling direction of the vehicle is straight, the lane information and the speed information of the vehicle are acquired.
Specifically, when the driver is judged to be driving straight at the traffic intersection, only the lane information and the speed information of the vehicle need to be acquired at the time, and the motion track of the vehicle is simulated.
S1014, when the vehicle turns in the traveling direction, acquires the lane information, the speed information, and the turning information of the vehicle.
Specifically, when the vehicle turns in the traveling direction, lane information, speed information, and turning information of the vehicle are acquired, and the movement locus of the vehicle is simulated.
In an embodiment of the application, the acquiring of the driving information shown in steps S1011 to S1014 can be completed on the vehicle, the image acquisition device on the vehicle acquires the behavior information of the driver and transmits the acquired behavior information to the controller on the vehicle, the controller analyzes the behavior information of the driver and judges the driving information (straight or turning) of the vehicle, and then the controller on the vehicle sends the driving information to the terminal device for managing the traffic intersection, so as to sequentially complete the acquiring of the driving information of the vehicle by the terminal device.
And S102, creating a simulated motion track of the vehicle in a preset map based on the running information.
Specifically, after the driving information of the vehicle is acquired in step S101, a simulated motion trail of the vehicle is created in the preset map, where a starting point of the simulated motion trail is a current position of the vehicle, and a terminal of the simulated motion trail is a position where the vehicle drives out of the preset map.
And S103, determining collision points of any two vehicles in a preset map according to the simulated motion track, the parameter information and the driving information.
Specifically, a plurality of vehicles may be simultaneously present in the preset map, a simulated motion trajectory of each vehicle is created through step S102, and then two vehicles colliding within the range of the preset map may be determined according to the parameter information and the driving information of the vehicles, and a specific position where the two vehicles collide can be determined.
For example, the method for determining the collision point of the vehicle may include:
and S1031, acquiring two target vehicles with crossing points on the simulated motion tracks in a preset map.
Specifically, when the simulated motion tracks of two vehicles in the preset map have no intersection, the two vehicles do not collide; when the simulated motion trajectories of the two vehicles have an intersection, the two vehicles may collide.
S1032 determines whether the two target vehicles collide at the intersection point based on the traveling information and the parameter information of the two target vehicles.
S1033, in the case where two target vehicles collide at the intersection, the intersection is determined as a collision point.
In particular, when the movement trajectories of two vehicles have an intersection, there is a possibility that the two vehicles may collide. Step S1031 determines two target vehicles that may collide, and then analyzes and determines whether the two vehicles may collide by analyzing the simulated movement trajectories, the travel information (including lane information, speed information, turning radius, etc.), and the parameter information (including size information of the vehicles, etc.) of the two vehicles.
And S104, respectively sending alarm information to the two vehicles with collision points in the preset map.
Specifically, when the two vehicles are judged to have the possibility of collision in the preset map, alarm information is sent to the two vehicles respectively, a driver is reminded to collect measures in advance, and collision is avoided.
Illustratively, after collision points of two vehicles are determined, a first preset range and a second preset range are set by taking the collision points as circle centers, the maximum value in the second preset range is smaller than the minimum value in the first preset range, and when the distance between the vehicles and the collision points is the first preset range, common alarm information is sent to the vehicles; and when the distance between the vehicle and the collision point is a second preset range, sending emergency alarm information to the vehicle. For example, the first preset range is 30-80 meters, the second preset range is 0-30 meters, when the distance between the vehicle to be collided and the collision point is 30-80 meters, the common alarm information sent to the vehicle is rhythmic 'dripping' sound, the driver is reminded to collect measures to avoid collision, and the driver has sufficient time to collect measures; when the distance between the vehicle which is about to collide and the collision point is 0-30 m, the emergency alarm information sent to the vehicle is a sharp drop sound, and a driver is reminded to take emergency measures to avoid collision.
When the vehicle passes through the traffic intersection, the terminal equipment acquires the driving information of the vehicle in real time, updates the simulated motion track of the vehicle in real time according to the acquired driving information, updates the determination of the collision point, and sends alarm information to the vehicle when the collision point still exists after the updating; and when the collision point disappears after updating, the alarm information is not sent to the vehicle.
Fig. 3 is a schematic flow chart of a traffic intersection management method according to an embodiment of the present application, where the traffic intersection management method includes steps S101 to S104 in fig. 1, and the work flow is consistent with the work flow in fig. 1, and in addition, before step S101, the method further includes:
s1001, a connection request signal of a vehicle is acquired.
Specifically, the controller on the vehicle sends a connection request signal all the time, and when the vehicle enters a preset map range when the vehicle enters a traffic intersection, the terminal device starts to acquire the connection request signal of the vehicle.
And S1002, establishing data communication connection with the vehicle according to the connection request signal.
Specifically, after the terminal device acquires a connection request signal of a vehicle, data communication connection with the vehicle is started according to a set communication protocol, after the terminal device establishes data communication connection with the vehicle, driving information and parameter information of the vehicle can be acquired, a simulated motion track of the vehicle is established in a preset map according to the driving information of the vehicle, a collision point of the vehicle in the preset map is determined according to the simulated motion track, the driving information of the vehicle and the parameter information, and finally alarm information is sent to the vehicle which is likely to collide, so that a driver is reminded to collect measures to avoid collision, and therefore the safety of the vehicle passing through a traffic intersection is improved.
In order to clearly illustrate the specific flow of the traffic intersection management method, a specific scenario is described below.
Scene one

As can be seen from the simulated motion trajectories of the two vehicles in FIG. 4, the distance between the head of the vehicle M and the o point is s1The time required for the head of the vehicle M to reach the o point is
Considering the influence of the length of the vehicle body, the time required for the tail of the vehicle M to leave the o point is
The running radius of the vehicle N is
The included angle formed by the vehicle N and the o point relative to the terminal device X is theta, and the distance between the vehicle N at morning and the o point is s2＝θ*R0The time required for the head of the vehicle N to reach the o point is
After the head of the vehicle N reaches the o point, the subsequent motion track is simplified and is regarded as linear motion, and the influence of the length of the vehicle body is considered, so that the time required for the tail of the vehicle N to leave the o point is equal to
There are two cases in which the vehicle M collides with the vehicle N:
a1: when t is1≤t3≤t2When the vehicle M reaches the point o before the vehicle N, but the tail part of the vehicle M does not leave the point o when the vehicle N reaches the point o, the two vehicles collide with each other, and at the moment, the terminal device X sends alarm information to the vehicle M and the vehicle N respectively.
B1: when t is3≤t1≤t4When the vehicle N arrives at the point o before the vehicle M, but the tail part of the vehicle N does not leave the point o when the vehicle M arrives at the point o, the two vehicles collide, and the terminal device X can move to the point oThe vehicle M and the vehicle N respectively send alarm information.
After the vehicles arrive at the traffic intersection, the terminal device X judges the vehicles with the priority right of passage according to the simulated motion tracks, the running information and the parameter information of the vehicles and the traffic rules, calculates whether the vehicles have collision conflicts or not in real time according to the real-time speed, and feeds back the results to the relevant vehicles in real time.

According to the actual traffic situation, the two vehicles are probably collided with the point Q of the area C at the earliest and are probably collided with the point Q or the point p of the area C at the latest.
As can be seen from FIG. 5, the distance between the head of the vehicle Z and the point Q is s3The time required for the head of the vehicle Z to reach the point Q is
Considering the influence of the length and width of the vehicle body, the time required for the tail of the vehicle Z to leave the collision region C, i.e., leave the point q, is
The time required for the head of the vehicle Y to reach the point Q is
Considering the influence of the length and width of the vehicle body, the time required for the tail of the vehicle Y to leave the collision region C, i.e., leave the point p, is
In the case of a vehicle collision, there are two main situations:
a2: when t is5≤t7≤t6When the vehicle Z arrives at the point Q of the collision area C before the vehicle Y, but the tail of the vehicle Z does not leave the point Q of the collision area C when the vehicle Y arrives at the point Q of the collision area C, the two vehicles collide with each other, and at this time, the terminal device sends alarm information to the vehicle Z and the vehicle Y respectively.
B2: when t is7≤t5≤t8When the vehicle Y arrives at the point Q of the conflict area C before the vehicle Z, but the tail part of the vehicle Y does not leave the point p of the conflict area C when the vehicle Z arrives at the point Q of the conflict area C, the two vehicles collide, and at the moment, the terminal device sends alarm information to the vehicle Z and the vehicle Y respectively.
After the vehicles arrive at the traffic intersection, the terminal equipment judges the vehicles with the priority right of passage according to the simulated motion tracks, the running information and the parameter information of the vehicles and the traffic rules, calculates whether the vehicles have collision conflicts or not in real time according to the real-time speed, and feeds back the results to the relevant vehicles in real time.
For example, if a collision conflict condition a2 occurs, the terminal device will alert vehicle Y to slow down its brakes; meanwhile, the vehicle Z is reminded to pay attention to the right-side straight-going vehicle, and the collision early warning effect is achieved.
If a collision conflict condition B2 occurs, the terminal equipment warns the vehicle Z to brake, slow down and drive; meanwhile, the vehicle Y is reminded to pay attention to the left-side straight-going vehicle, and the collision early warning effect is achieved.
