Data collection method analysis for evaluation of public transport system performances

There is an ongoing research on the implementation of public transport (PT) priority system in City of Zagreb within CiViTAS ELAN project, co-funded by the European Union. Within the project framework, specific objectives are defined and on that basis the evaluation activities are set up by defining evaluation indicators. For this purpose, a special group of performance indicators is used for the evaluation of PT priority system. A segmentation of vehicle operation time is introduced, where each time segment of PT vehicle operation time is measured and evaluated separately in order to detect the changes, even in the small time segments. In this paper four data collection methods for the performance indicators are analyzed: manual time recording, GPS vehicle tracking, PDA computer system and manual video data processing. After the comparative analysis of those methods, several use-case scenarios are defined in order to point out preferable combination of methods for this type of measurements. Use-case scenarios describe different traffic situations in PT vehicle itinerary which are in close relation to PT station location and PT vehicle occupancy.
