Theoretical analysis of the operations of PUFFIN pedestrian crossings

The PUFFIN crossing uses two types of pedestrian detectors, the on-crossing detectors within the crossing area and kerbside detectors within the waiting area on the footway. The on-crossing detection is used to automatically vary the length of the pedestrian clearance period, giving pedestrians the time they need to cross, while the kerbside detection is used to cancel the pedestrian demand call if the pedestrian leaves the crossing after pressing the call button. A theoretical study investigating the performance of PUFFIN crossings to investigate the problem of pedestrian delays is outlined. Basic PUFFIN operations are described. The average vehicle green time and the average pedestrian all-red duration are modelled and a method of estimating the vehicle queues and the number of pedestrians is presented
