A fuel-saving and congestion-easing traffic light system is under development.
Built by Belgrade-based designer Damjan Stankovic, the Eko light's right light has an LED countdown on it.
Stankovic says this allows motorists to prepare for driving away as quickly and as efficiently as possible and without out any delay. It also means drivers are able to turn off their engine, safe in the knowledge they won’t be caught out by an abrupt green light.
Although its makers hope the Eko light will be trialled around Europe, no cities have committed to installing the system yet.
