Countdown Timers Enhancing Road Safety

Countdown timers are useful accessory to enhance safety and diminish undesirable behavior of drivers and other road users.

They indicate the time remaining until red or green phase and thus positively contribute to better orientation and less risky behavior of all road users at junctions.

For instance, countdown timers at red lights warning drivers how much time is left before the light changes can help to ease traffic flow.

It was found that the presence of the countdown timers at the intersection would help to reduce the start-up lost time at the beginning of the green phase by 22%, and reduce the number of red-light violations during the beginning of the red phase by 50%.

Furthermore, more than half of the local drivers reported that the timers help to relieve the frustration caused by stopping for uncertain amounts of time during the red phase.

The research has shown that after a period of 30 to 45 seconds of waiting, pedestrians become more risky, impatient and were more likely to cross whenever they could regardless of the pedestrian signal displays.

This risky behavior might be eliminated by presence of countdown timers as pedestrians are aware how much time is left.
