Trajectories Prediction of Vehicles at the Intersection Based on LSTM Neural Network

More and more non-motorized vehicles (including bicycles and electric bicycles) are pouring into the intersections, making the intersections’ environment more complex. The traffic accidents related to the vehicles and non-motorized vehicles at the intersections are serious. In this paper, vehicle trajectory sets are extracted at the intersections by using the video detection technology. The trajectory prediction model of motor vehicles based on the long short term memory neural network training is obtained, which consider the influence of non-motorized vehicles. The trajectory prediction model based on LSTM is used to predict the trajectories of the vehicles passing through intersections. The overall approach was tested on real trajectories sets at specific intersections and results show that the model has a high success rate and the final trajectory prediction has a better accuracy.
