| Abstract: | The traffic flow characteristics and accident reasons in the passageway areas of freeway were analyzed.Based on vehicle critical deceleration and unsafe degree,risk level was changed from two dimensional vector to one dimensional scalar.Braking decelerations and unsafe density indexes were put forward as the driving risk evaluation indexes of passageway areas,and a driving risk evaluation model was established.According to safety risk management regulations and human-mechanism engineering theory,risk grades... |
