A following behavior detecting method for drive assistance

This paper addresses the concern of the following behavior of vehicles. A following behavior detecting method is proposed for alerting victim drivers based on surrounding vehicle trajectories. In order to detect the suspicious vehicle intention, i.e. whether the suspicious vehicle is following the victim vehicle or not, the proposed method analyzes various behavior features. These features are detected according to suspicious vehicle position, velocity and acceleration relative to the host/victim vehicle. A following behavior model is then proposed for intention detection via behavior data analysis. A Neural Network (NN) classifier is employed to validate the proposed behavior model. Experiments show that the proposed method is effective.
