With major roundabouts making way for signal junctions, the need of the hour is to make traffic signals more efficient and user-friendly.

As it is happening now, when the traffic is lean, motorists wait impatiently for the red light to turn green. This problem can be solved by installing ‘vehicle actuated signals’ at major junctions. Based on the density of vehicles, which is picked up through sensors, the signals change automatically. If vehicles move on without long stops, an enormous amount of time and fuel will be saved.

Another requirement is for ‘timers’ at signals. Advantages are:

1. Timers allow motorists to relax, as they know the duration of their wait at signals.

2. Saves fuel and reduces pollution levels when the engine is switched off.

3. Timers help pedestrians who have a clear idea about the time left to cross the road.
