Abstract:

To deal with the problem of traffic accidents such as vehicle collision during the conscious lane change of the vehicle on the highway under dangerous conditions, a now safety lane change model was established on the basis of the previously studied and developed lane departure warning system. The model considered the typical lane change scenario and more actual behavior that most driver often accelerate their vehicles during the lane change process. A simulation program was developed to analyze the model performance based on the software Matlab 7.0. The established model was compared with the developed by California University and the result showed this model is more practical. It can be used to establish the vehicle assistant driving system for lane change.

Key words: transportation safety engineering, lane change, assistant driving, simulation
