Model of Motor Vehicle Traffic Conflicts at Urban Intersections Based on Angle Recognition
摘要
In order to improve the recognition accuracy of motor vehicle traffic conflicts at urban intersections, the conflicts between motor vehicles at intersections were recognized to establish a new traffic conflict recognition model based on the high precision trajectory data from the radar and video all-in-one machine at holographic intersections and in combination with complete vehicle motion information. Conflict categories were identified; and the method for determining the severity of vehicle traffic conflicts was provided. Points and severity of conflicts at an intersection in Beijing were recognized. The quantitative description of potential safety risks at this intersection was identified.
