Pedestrian crossing criteria research - Random crossing model

This report describes the results of surveys of pedestrian behaviour and delays when crossing the road at random points within a 100m section of road at 45 locations in England and Wales. The surveys included both two way roads, with and without a central refuge, and one way roads. Methods of representing pedestrian behaviour using decision matrices, and vehicle inter arrival time distributions using a double displaced negative exponential distribution, have been developed from the survey results and applied to develop a simulation model which predicts pedestrian delay. The simulation model has been calibrated to show good agreement with site recorded data. The simulation model has been applied to generate a database of pedestrian delay corresponding to specified levels of pedestrian and vehicle flow. For each of a range of layouts a simple model of 24 hour pedestrian delay based on five hour counts of pedestrian and vehicle flow has been derived from the database using generalised linear modelling techniques.
