London Buses have implemented a new Automatic Vehicle Location (AVL) system called iBus. Like most other AVL systems iBus requires good quality network data in order to function correctly. This paper demonstrates how London Buses has made significant use of GIS and Electronic maps to provide accurate data to iBus. High quality maps have been used to measure the location of bus-stops, and to plot the roads that each route serve, as well as the roads taken when a bus changes direction. GIS systems have then used this data to calculate the heading of each stop, distance between stops, and the last stop visited by a bus if it curtails. In addition, a novel validation technique has been implemented. This validation technique identified over 1,500 errors in London Buses data. London Buses were able to correct these errors before iBus was rolled out on all 673 bus routes. This has resulted in the successful launch of iBus. This paper thus demonstrates how GIS can greatly assist in the successful implementation of AVL systems.
