‘Ordinary cyclists’ and experts often agree about the bicycle friendliness of a traffic control system (TCS). The waiting time at such junctions is a good indicator of bicycle friendliness and this is strongly related to the system’s cycle. The shorter the cycle the better, but longer than 90 seconds is not appreciated. Good management and maintenance can considerably reduce the waiting times at many junctions, but much more can be gained from involving the traffic engineer in the construction of a junction from the start. However, cyclists can expect most benefit from a clear policy which takes into account the priorities for the various types of road user and the consequences for other forms of transport.
