Automating Bus Stop Dwell Times Measurements using London’s iBus: Exploiting the Data from Vehicle Location Systems

Automatic Vehicle Location (AVL) systems for buses have been deployed successfully in many cities to improve service operations and provide real-time passenger information. Increasingly these systems are being used to develop further applications, and this paper provides one example using London’s iBus, where events captured historically by vehicles operating on-street in real-time are used to derive automated bus stop dwell time measurements, which are comparable to the observations made on-board vehicles, and the values obtained previously through manual surveys. The method involves running complex algorithms to process large volumes of events log records taken from the small on-board computers of iBus-enabled vehicles, and using these to calculate the Speed Zero durations or stationary times of buses within the stop zone. This method may have similar application in other cities, and has the potential to replace relatively expensive manually surveys, and provide improved dwell time measurements for use in bus priority, for service scheduling, journey time planning and in public transport modelling.
