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.

    Someone once likened predicting the future to ‘nailing a jelly to the wall’. With ITS, C-ITS and V2X technology progressing at such a pace, predicting the future is more akin to trying to nail three jellies to the wall – but only having one nail. And yet with roadways having a lifetime measured in decades, that is exactly what highway engineers and traffic planners are expected to do. Fortunately, New Hampshire DoT (NHDoT) believes its technological advances may be able to provide a solution. The Central Ne
