A New Vehicle Safety Space Model Based on Driving Intention

According to statistical data, vehicle rear-end collision takes a large proportion of all kinds of accidents. In order to reduce the rate of rear-end collision, the vehicle safety spacing model was extensively studied. Driving Intention reflects drivers´ behavior during driving process. Therefore, a lot of scholars have studied the relation between driving intention and safe driving. In this paper, a new model on vehicle safety spacing is proposed, which considers the brake intention of the rear vehicle. It assumed that the rear vehicle intention can be transmitted to leaded vehicle in real time. Field experiments were designed to verify the improvement of new model. The driver´s operation and vehicle´s dynamic data were collected by sensors and analyzed in MATLAB software. The simulation results show that the vehicle safety spacing of proposed model is 30m farther than that of the model without consideration of driving intention. It can be concluded that the safety spacing model with driving intention can be successfully constructed and the proposed model is more effective at preventing rear-end collision.
