    Abstract
  • In order to directly and objectively identify road accident black spot from road conditions coupled with vehicles, a dynamics system of simulation and identification for road accident black spot was developed, vehicle model, road model and vehicle-road coupling model were set up, a identification method of road accident black spot was put forward, and the feasibility of the system was validated by using dynamics simulation examples when vehicle running on small cling coefficient road and braking on curve road. The running states of vehicle were controlled by using close-looped control method, the character parameters of running safe states for vehicle were chosed according to road characters, and road accident black spot was identified according to the curves of the parameters. Dynamics simulation result shows that the identification result is consistent with the accident statistic analysis result from the department of point constable when main considering road factors, so the system is feasible.
