Abstract

This paper performs an analysis of the influence of headway irregularity in public transport on the quality of the transport service, in the domain of in-vehicle passenger comfort. The influence of vehicle headway irregularity along a route on the in-vehicle passenger comfort has been analysed on urban bus routes that operate in a mixed traffic flow. Based on the research conducted on 2,800 bus departures, the headways and capacity utilizations have been determined for every individual vehicle along a route. On the recorded departures, the capacity utilizations have been analyzed in real working conditions. Based on the real recorded capacity utilizations (with headway deviations) and simulated capacity utilizations (without headway deviations), a comparative analysis has been performed on the influence of headway irregularities along a route on the capacity utilizations, that is, on in-vehicle passenger comfort.

Key words: Transport service quality, headway irregularity, capacity utilization, in-vehicle comfort.
