The paper describes briefly the contrasting data collection techniques in two cities, and the relationships that have been developed for each. The resulting equations are then compared, and conclusions drawn on the appropriateness of each for use in public transport assignment. In Christchurch, the buses have recently been equipped with GPS devices, and on all routes are sampled twice a minute to about 10 metres accuracy. From this data, the time spent moving, time stopped at intersections, and the deceleration time spent at the bus stop, and acceleration time back into the traffic stream can be separately identified. In contrast to the ITS technology of Christchurch, a major public transport study is under way in Kuala Lumpur, including a significant data collection exercise. One of the surveys (an on-board bus survey) has collected distance and time information for a significant sample of bus routes in KL. It has provided empirical data on bus performance in terms of time spent moving, clearance and service times at stops, average journey speed as well as journey speed at different sections.
