Over the next few years all relevant traffic lights in the province will be modified. The idea of this green light scheme is that with rain, a temperature below 10 degrees Celsius or with minimal car traffic cyclists will receive two or three times per cycle a green light, instead of once only. In order to ascertain weather conditions, a rain sensor and thermometer have been linked to the traffic light system. Provincial authorities manage 85 traffic light systems overall. A number of these do not possess bicycle crossing facilities. In addition a number of regulated intersections will be transferred to other authorities or turned into roundabouts. This means that the remainder, 39 locations, will be modified over the next few years.
