| titleOfInvention | Vehicle track prediction method of two-dimensional intelligent driving model based on virtual boundary |
| abstract | The invention discloses a vehicle track prediction method based on a two-dimensional intelligent driving model of a virtual boundary, which is a method for describing complex traffic behaviors at ramps and accurately predicting vehicle tracks in a mixed traffic flow environment of a multi-lane road. The method comprises the steps of generating a virtual boundary line in consideration of the topological structure of a road, and then obtaining state information (transverse and longitudinal coordinate positions, speed and acceleration) of a target vehicle (a vehicle needing to predict a track) and surrounding vehicles at the current moment; then calculating the relative effective distance and the relative average speed between the target vehicle and the surrounding vehicles (in the front direction, the rear direction, the left direction and the right direction), and the distance between the target vehicle and the virtual boundary line; and then calculating the state information of the target vehicle at the next moment according to the two-dimensional intelligent driving model based on the virtual boundary, repeating the previous steps, continuously calculating the state information of the target vehicle at the next moment, and finally forming a complete vehicle track. |
