Non-conflict discrimination of roundabout machine based on gap acceptance theory
In order to accurately determine the non-collision of the exit lane of the roundabout,this paper uses the video trajectory tracking software Tracker to extract the conflict traffic flow trajectory data of motor vehicles and electric bicycles crossing the street,selects the deceleration discrimination method as the criterion for determining the occurrence of traffic conflicts,and uses the Raff method in the gap acceptance theory to determine the critical value of deceleration.The conflict at the roundabout of Gulou Square in Nanjing was judged by chance,and the discrimination result was obtained.
