Abstract
This invention relates to a method for calculating the traffic safety factor of a road segment, an electronic device, and a storage medium, belonging to the field of traffic simulation technology. To flexibly assess traffic safety at various stages of highway projects and for any road segment, this invention constructs a basic simulation road network model based on the road design scheme. Then, simulation model parameters are set and corrected to obtain the simulation road network model. The obtained simulation road network model is run to extract and calculate vehicle trajectory data, including extraction time, vehicle coordinate position, and instantaneous speed data. The average speed of all vehicles passing through the test road segment within a unit of time is calculated. Based on the average speed of all vehicles passing through the test road segment within a unit of time, the traffic safety factor of the road segment is calculated, and the traffic operation safety of the road segment is analyzed. This invention can assess the traffic operation safety of any specified road segment.
