Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] attached figure 1 It is the resolution process of two-vehicle conflict at an unsignalized intersection, which consists of vehicle information collection and preprocessing, vehicle-vehicle conflict risk identification, vehicle-vehicle conflict type judgment, conflict vehicle priority judgment, conflict resolution strategy determination, and conflict resolution strategy execution. Form a loop.

[0022] The information collected by the vehicle is the latitude and longitude coordinates of the two vehicles (B i , L i ), track angle ψ i , speed v i , Angular velocity ω i and acceleration a i , using the Gaussian projection theory to transform the latitude and longitude coordinates into Gaussian plane coordinates (X i , Y i ), and then perform Kalman filtering on the Gauss plane coordinates, track angle, velocity, angular velocity, and acceleration of...

Abstract

The invention discloses a method for eliminating a traffic conflict of two vehicles at an intersection without a signal. The method comprises the following steps: vehicle information collection and pretreatment; vehicle-to-vehicle conflict danger identification; vehicle-to-vehicle conflict type determination; determination on a conflict vehicle priority; determination on a conflict elimination strategy; and execution of the conflict elimination strategy. According to the method provided in the invention, driving security of vehicles can be improved and a road passing efficiency can also be enhanced.

Description

technical field [0001] The invention relates to a method for resolving traffic conflicts between two vehicles at an unsignalized intersection. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the number of motor vehicles has increased rapidly, resulting in a sharp contradiction between traffic demand and road facilities. This has brought a lot of problems to urban roads, especially to level intersections in urban road networks. Level intersections are concentrated areas where vehicles with different flow directions conflict. Reducing traffic conflicts at level intersections is the main way to improve the traffic capacity of urban roads. One of the methods. [0003] At present, cities usually use traffic signal control and traffic channelization to reduce traffic conflicts, but for intersections with relatively small traffic flow, these methods will inevitably cause waste of resources. With ...
