Abstract

Time separation by means of traffic signals is the most widely used method of providing opportunities for pedestrians to cross arterial roads safely. This form of traffic control necessarily implies delays for both pedestrians and vehicle occupants and puts these two groups in competition for time with exclusive use of the crossing. The evaluations described in this paper demonstrate that, compared with signal strategies that use a fixed time for the pedestrian phase on every signal cycle, strategies that allow flexibility in the duration of the pedestrian phase can yield significant and simultaneous benefits for pedestrians and vehicle occupants. Optimising the length of the signal cycle can also benefit pedestrians at minimal cost to vehicle occupants. These strategies should receive increased attention as ways are sought to reduce congestion and achieve ambitious casualty reduction targets.
