Best Practices for Traffic Signal Operations in India

The problem of traffic is a complex one requiring design, planning, engineering and institutional inputs for developing a proper solution. Dealing with traffic at crossroads requires, many a times, the study and installation of traffic signals. Signalized intersection locations form the most common bottleneck points in cities across the world. Traffic in Indian cities add more levels of complexity through heterogeneity, lack of discipline, inconsistent geometric design – to name a few. This document, using a combination of review and modelling provides a set of best practices for traffic signals for Indian cities that could be implemented at a rule-of-thumb level to improve the efficiency of traffic signals in terms of vehicle handling capacity and reduction in delays, vehicles idling and emissions.
