Given the current attention on transport system related challenges concerning climate emissions, air pollution and congestion in cities, there are great aspirations to increase the volume and share of passengers using public transport. Among other things, this demands that services should be improved. One type of improvement is to increase the speed of buses and improve regularity. Doing so will make bus services more attractive, which in turn may help to increase public transport. In congested areas, speed and regularity may be improved through the implementation of measures such as bus lanes, signal priority at traffic lights, a reduction in the number of bus stops, and the re-designing of crossroads, etc., measures that are often framed within the term “bus priority measures”.
