Calculation of the delays of autonomous vehicles at signalized intersections using the Webster method

Abstract

Traffic lights as one of the key components at intersections, have an important role in the control of traffic flow. Delays occurring at signalized intersections significantly affect the travel time. Hence, coordinating intersections is one of the most effective ways to achieve a steady flow of traffic. By means of illuminated and signalcoordinated intersections, the delay time, queue length, and travel time of vehicles moving on arterial roads may be significantly reduced. Autonomous vehicles developed within the scope of todays technology have now become a part of transportation systems. This paper evaluates the effectiveness of autonomous vehicle systems to minimize delays at intersections.
