Priority to buses as part of traffic management.

Bus priority schemes, in particular bus lanes, are studied in three ways: 1) controlled test-track experiments, 2) theoretical simulations, and 3) and 3) studies of actual bus lanes. A controlled experiment carried out on the Laboratory test track is described, and some results showing how the saturation flow of cars and the time savings to buses are affected by the position of the end of the bus lane relative to the stop-line are given. Summarized results of ten actual bus-lane schemes are presented.
