Study on User Delay at Signalised Intersection and Formulation of Level of Service

Intersections are the nodal link in a road network as these accommodate different types of movements of traffic including crossing movements of both Motorised Transport (MT) and Non-Motorised Transport (NMT). At uncontrolled intersections, the movement pattern of vehicles at the intersection creates conflict points between MT-NMT, MT-MT and NMT-NMT. This makes intersections the most vulnerable and unsafe location in any road network. One method to reduce the conflict points at an uncontrolled intersection is to convert it into a controlled intersection, where streamed traffic movements are allowed at the intersection. Signalised intersections are one such form of intersection, where traffic movements are controlled through the operation of traffic signals. The operating characteristics of the traffic signal primarily depend on the traffic flow characteristics, geometry of the road, layout of the intersection and the behavioural aspect of the road users. Level of Service (LoS) is the widely adopted term to determine the efficiency of any transport system. The LoS is used by the decision makers to evaluate, identify and suggest improvement measures of the intersection. Since no unique Level of Service measurement criteria considers the MT and NMT users together, the improvement measures on MT may adversely affect the NMT and vice-versa. This raises the need for a representative Level of Service for signalised intersection, which explains the level of service of the whole intersection incorporating the motorised and non-motorised modes of the traffic.
