Green wave for cyclists

Case study

On a 2.2 km long section of Nørrebrogade between Nordre Fasanvej and Dronning Louises Bro, 12 subsequent traffic lights are synchronised for travelling at the speed of 20 km/h following the dominating direction of traffic: between 6:30 and 12:00 in the direction of centre, between 12:00 and 18:00 in the direction of suburbs. The green wave for bicycles is coordinated with green wave for buses, taking into account the location of bus stops and the average time a bus spends stopped at them.

Introduction of the green wave for cyclists resulted in an increase in average speed from 15.1 to 20.7 km/h. This means a reduction of travel time by 2.5 minutes (nearly 30%) over just 2.2 km.
