Pelican crossings-The development of a simulation model to evaluate operating strategies

The paper reviews the development of Pelican crossings and describes the application of simulation techniques to evaluate the effects of operating strategy and aspect durations on pedestrian and vehicle behaviour characteristics and delay. The selection of appropriate methods of representing vehicle arrival times, particularly for crossings located in close proximity to signal controlled junctions, is discussed and a technique to generate vehicle arrivals in platoons is described. The effects of lane changing and queueing on vehicle delay are also considered. Stability criteria, which provide results reasonably typical for a Pelican crossing as defined by the input data, are described.
