Embodiment Construction
[0030] next combined with figure 1 A specific embodiment of the present invention is described in detail.
[0031] The vehicle collision avoidance method based on the vehicle-road coordination environment uses roadside equipment to improve the problem of limited long-distance perception of the current vehicle. With the vehicle-road coordination system, the vehicle will know in advance whether there will be an aircraft passing by the target lane, so as to The specific implementation method is as follows:
[0032] S1, the layout of roadside equipment, arrange roadside equipment at intervals on both sides of each traffic road, and communicate with each other between roadside equipment and between roadside equipment and vehicles and aircraft;
[0033] S2, the vehicle broadcasts the traffic status, and the vehicle driving on the road broadcasts its own traffic status to the roadside equipment in real time with a period T1;
[0034] S3. The roadside device calculates the road wher...

The invention provides a vehicle collision avoidance method based on a vehicle-road cooperation environment. The method is characterized by comprising the following steps that S1 roadside equipment are arranged, wherein roadside equipment are arranged on the two sides of each traffic road at intervals, and the roadside equipment communicate with each other and communicate with a vehicle and an airplane; S2, the vehicle broadcasts the traffic condition; S3, the roadside equipment calculate the road where the vehicle is located according to the obtained broadcast signal; S4, the runway of a target is screened out; S5, the airplaneclosest to the intersection is acquired; and S6, the collision time TTC of the airplane and the vehicle is calculated. According to the invention, the traffic efficiency of the airport is improved and the probability of traffic accidents of the airport is reduced by using the vehicle-road cooperation technology; and especially, due to some weather reasons, the visibility of an airport is limited, the sight of a vehicle working on the ground is limited, and if the vehicle is coordinated through the V2X roadside equipment, the running vehicle can be timely informed of the risk that the running vehicle collides with other vehicles or not, and then avoidance is carried out.
Description
technical field [0001] The invention relates to the field of traffic algorithms, in particular to a collision avoidance method for vehicles based on a vehicle-road collaborative environment. Background technique [0002] In recent years, with the increasing development of the aviation industry, air transport is no longer an expensive mode of transport as it was at the beginning, but has become a mode of transport that everyone can choose, so with the popularity of air transport, more and more More and more people will choose air transportation. However, with the popularization of air transport, the ground traffic at the airport is becoming more and more busy, which also brings a series of hidden dangers. [0003] However, with the development of vehicle-road coordination technology, airports can also arrange corresponding vehicle-road coordination environments to realize real-time traffic of vehicles, roads, and aircraft. In this vehicle-road collaborative environment, the...
