GlobalInsight: An LSTM Based Model for Multi-Vehicle Trajectory Prediction
ICC 2020 - 2020 IEEE International Conference on Communications (ICC)(2020)
Abstract
Intelligent Transport System (ITS) raises the increasing demand on accurate vehicle trajectory prediction for navigation efficiency. The rapidly developing 5G networks provides communications with high transmission bandwidth and super-low latency, paving the way for Mobile Edge Computing (MEC) to calculate more accurate trajectory prediction for vehicles, as the MEC server holds more comprehensive vehicular information. However, the current methods for trajectory prediction are not efficient due to the dynamical environment. To address this issue, we propose GlobalInsight, a Long Short-Term Memory (LSTM) based model, which runs on the MEC to perform accurate trajectory prediction for multiple vehicles no matter how scenario changes. In particular, we use three auxiliary layers to respectively capture the principal component of vehicle features, social interaction of adjacent vehicles, and the cross-vehicle correlation of similar vehicles. We further integrate the above information into LSTM in the main layer to enhance the trajectory learning and prediction. We evaluate our model under the NGSIM dataset, and experimental results exhibit that our model outperforms the state-of-the-art approaches.
