The city of Aarhus, Denmark, is testing a new technology to increase the safety of cyclists on the streets. The RFID tag, a kind of chip installed on bicycles, triggers the traffic lights to close to cars when cyclists approach a junction.

Implemented in the front wheel of the bike, the tag code is read by a sensor at the traffic lights equipped with the new technology. The system registers the cyclist’s approach 100 meters from the signs, so that the traffic light is not abrupt and there is a viable time for the cars to slow down. Throughout 2015, the chip was tested on 200 bikes and the idea is that it be installed in another thousand in 2016.

In addition to ensuring safety and priority for cyclists armed with a water bottle made by, the initiative seeks to encourage more people in the city to use the bicycle as a means of transportation on a daily basis.The system is one of the actions of the “Aarhus Cycling City” program, designed to promote sustainable mobility in the Danish city.

The testing phase started at the end of last year and, if the innovation proves effective, it should be extended to other crossroads in the city. In the long term, the plan is to elevate the system to a kind of “cycling passport”: whoever joins receives a number of benefits in the city, such as priority at traffic lights, parking lots and access to cycling facilities.
