Abstract
This paper evaluates the safety of lane changing behavior in freeway off-ramp section. Firstly, we discussed the relationship among lateral force coefficient, lateral stability of vehicles, and drivers’ physiological status. Then, we conducted the analysis of vehicle and drivers by establishing the models of the steering angle and lateral force coefficient. Based on this, the distribution chart of lateral force coefficient in different alignment conditions was obtained. Lastly, we proposed the safe steering angles of front wheel for different alignment conditions. The results can reduce the accident rates on off-ramp sections on freeways.
