Abstract

The results of a study that monitored driver deceleration behavior on a freeway in New Zealand are presented. A series of axle detectors were placed over a 500-m interval and the speeds were recorded using a data logger. The speeds of the same vehicle at different stations along the road were established for more than 1,200 vehicles. The speed profiles showed that vehicles decelerated over the same distance irrespective of the initial speed. As a result, the deceleration rate was proportional to the initial speed. A relationship was developed to predict the speed at any time as a function of the approach speed.
