Abstract [en]

This paper evaluates the effects of implementation of a range of physical and operational measures during a pilot study on the busiest and most frequent trunk bus line in Stockholm, Sweden. Vehicle positioning and passenger counts data were analysed to evaluate the impact of the field experiment. The study has proven that the bus service performance has been improved from both passengers and operator perspectives. These measures resulted with a service that is 7% faster on average yielding a 10% decrease in passenger in-vehicle times. The faster service leads to 8 minutes shorter cycle time which could potentially cut the fleet size by 2 buses. The results demonstrate that improved regularity and less bunching leading to a 25% reduction in passengers’ waiting times due to irregularity. However, no apparent change in dwell times has been observed. We estimate that each passenger saved 2 minutes which is 10% of journey time. These time savings amount to 9 million Swedish Crowns (1.1 million USD) per year for weekday afternoon peak periods only.
