Czech Republic deploying smart traffic lights to combat speeding

Municipalities in the Czech Republic are increasingly deploying smart traffic lights with radar that detects the speed of approaching vehicles and turns the signal red to slow them down to the required speed limit. Currently there are about 100 installations because mayors believe they are more efficient than speed cameras or speed humps. According to one mayor, over 90 per cent of drivers slow down because of the technology. The traffic light system contains a microwave radar sensor which measures speed. I

RSSMunicipalities in the Czech Republic are increasingly deploying smart traffic lights with radar that detects the speed of approaching vehicles and turns the signal red to slow them down to the required speed limit. Currently there are about 100 installations because mayors believe they are more efficient than speed cameras or speed humps. According to one mayor, over 90 per cent of drivers slow down because of the technology.

The traffic light system contains a microwave radar sensor which measures speed. If an approaching vehicle is travelling at lower than 50km/h, the light changes to orange and then green. If it is higher, the light remains red.

"The speeding driver sees the red and the throttles back. Red lasts until the car has achieved the required speed," explains Radomil Saiml Autron, the company which has supplied Czech municipalities with more than fifty of the new traffic lights.

Europe’s increasing use of this technology, which is widely deployed in Spain and Portugal, was the subject of a recent ITS International feature article - Traffic signals turn red to stop speeding drivers – by David Crawford which is available at this link.

On the face of it, Greater Manchester in England's proposed congestion charging scheme hit just about every sweet spot possible when it came to convincing the general public of the need for and benefits of such a venture.

Since the VW emissions story broke in September, emissions testing has come under greater scrutiny, and none more so than in Europe, where critics have long been highlighting the weaknesses of the testing system. Ironically, changes to the emissions testing process were already under review but the story has pushed it up the agenda.

By increasing average speeds and reducing travel times via the reduction in stops, the programme sought to reduce vehicle acceleration and deceleration events along the corridor; these have been identified as the leadin
