Abstract

The effect of traffic factors on the capacity of a traffic signal approach is usually allowed for by the use of weighting factors, referred to as ‘passenger car units’, assigned to differing vehicle categories. As a consequence the saturation flow of a signal approach or of a single approach lane is expressed in passenger car units per hour (pcu/h).
