Abstract

The uniformity issues of the traffic capacity indicator of controlled intersections are considered in the article from the standpoint of the traffic management features. The necessity of knowing the traffic capacity uniformity (in addition to its size) for the traffic management and optimization purposes is shown. This indicator is measured by standard deviation or variation coefficient. Traffic patterns in which hindrances from turning vehicles and pedestrian traffic in one phase reduce the uniformity of capacity are presented. Because of this, the efficiency of signal control decreases, and the queue length and the overall delays of vehicles increase. The article distinguishes 3 patterns of traffic management at a controlled intersection in terms of hindrances caused by the movement of pedestrians and turning flows, affecting the uniformity indicator. The conclusions of the article are confirmed by conducting a multifactorial experiment with finding statistically significant coefficients.
