摘要

Rear-end collisions are the most common type of automobile collision in modern traffic situations, and they have attracted much concern from both traffic safety engineers and travelers. In many cases, however, research that has focused on whether cars follow each other too closely has provided only a narrow insight into human factors. Therefore, this paper offers a basic method to estimate the emergency braking distance of passenger vehicles with respect to the following interval that should be kept as a "gap" between two consecutive vehicles moving in a lane. Four phases of the overall braking process are summarized-the reaction lag, deceleration by the vehicle engine, deceleration by the brake system and full deceleration-and equations are developed to describe the minimal traveling interval between consecutive arrivals, which varies with the pavement conditions, traveling speed and traffic intensities. Since traffic is not constant and probabilistic laws are involved, a Poisson distribution model is presented to estimate the probability of vehicles passing a fixed point within a given interval, so as to assess the risk-taking level of a traffic platoon. Two numerical examples show that vehicles on wet roads have braking distances longer than that suggested by the two-second rule. In addition, the level of risk taking in higher intensity traffic is unexpectedly higher, which could be interpreted as motorists behaving more aggressively and more likely to accept shorter following distances and higher speeds because they believe that they have the ability to swerve to avoid a collision.
