Analysis on Traffic Safety Distance of Considering the Deceleration of the Current Vehicle

摘要

In the light of the conditions that the results of traditional criticality safety vehicle distance are hardly able to guarantee the safety in the sudden reaction of the current vehicle, through studying the conditions of traditional criticality safety distance, considering the impact of abnormal deceleration of the current vehicle on following vehicle, and different response time of drivers, a new calculation method is re-established for criticality safety distance. It not only can meet the demands safety of expressway better, but also has positive significance for the prevention of rear-end collision.
