Effect of Control Delay in Traffic Control and Management of Arterial At-Grade Signalize Road Intersections

Sukanta Karati, Amartya Ray

This paper is an attempt to address the control delay in traffic control and management of arterial atgrade signalised road intersection. Delay is the one way to measure the interruption traffic flow. Control delay is defined as the total delay, which is occurred at signalised intersection. Control delay depends on types of signal as well as cycle time of signal, degree of saturation, queue of vehicles, peak factor, progression factor and condition of carriageway and geometric features of pavement. Control delay includes initial deceleration delay, queue move-up time, stopped delay and final acceleration delay. The length of average control delay can be found out to use an equation at various signalized intersection. To objectives of this research study were to analyse difference way to minimize the control delay and maintain the rapid flow, to improve the speed of vehicle, increase the traffic carrying capacity and remove traffic congestion
