Example Embodiment
[0068] The present invention will be further described below in conjunction with specific embodiments.
[0069] Such as figure 1 As shown, the method for evaluating traffic safety at unsignalized intersections in this embodiment includes the following steps:
[0070] 1) Select the intersection to be studied and obtain basic data, including four aspects of information in total: intersection geometry information, intersection traffic management strategy, intersection traffic flow data and vehicle-related parameters;
[0071] 2) The basic data processing of intersections, the establishment of a coordinate system and grid division;
[0072] 3) Solve the conflict probability of each grid, assign values to the grid inside the entire intersection, and construct a conflict probability matrix;
[0073] 4) According to the conflict severity kinetic energy loss model, solve the possible conflict severity of each grid, and assign values to the grids in the entire intersection;
[0074] 5) Consi...
