THE EFFECTS OF PELICAN CROSSING FACILITIES IN A LINKED SIGNAL SYSTEM: A SIMULATION STUDY
Research conducted into the prediction and means of minimising the delays incurred by both vehicles and pedestrians at light-controlled pedestrian crossings have led to the setting up of recommendations which increase pedestrian safety but also increase vehicle delay. Within a co-ordinated area traffic control system the signal settings are almost always calculated to minimise vehicle delay. In broad terms, this reduces costs both to drivers and to the environment. Pedestrian crossings, on the other hand, which increase vehicular delay may be seen to be in direct conflict with this strategy. Simulation models have been used to study the effects of pelican pedestrian crossings operating within co-ordinated signal systems to consider how the delays to both types of user may be minimised by selection of appropriate crossing locations and signal timings.
