Signalised road intersections in Indian cities are hotspots of vehicular emissions and poor air quality as inappropriate signal timing cycles increase delays and vehicle idling at intersections. Improving efficiency of traffic signals to handle traffic can reduce vehicular emissions at signalised intersections by 20-30 per cent in most situations. This report provides an overview of best practices that can be implemented at a rule-of thumb level to improve the efficiency of traffic signals in terms of vehicle handling capacity, reduction in delays, vehicle idling and emissions.
