A demand-responsive bus system for peak hours with capacitated vehicles

Book Contribution - Book Chapter Conference Contribution

When demand for transportation is much higher in one direction than in the opposite direction, buses are often overcrowded in one direction and almost empty in the other. This happens mostly because of the lack of flexibility during operations of most traditional bus systems. To provide a better service, many demand-responsive systems have recently been studied. Vansteenwegen et al. (2022) provide a literature review on such systems. To improve the efficiency of service in a corridor with uneven demand, Furth and Day (1985) suggest applying stop-skipping. The authors provide valuable input on the advantages and disadvantages of several strategies, however, the optimization of the systems are still lacking. In this study, we focus on a single line where the demand for transportation in one direction during peak hours is much larger than the demand in the opposite direction and the demand outside peak hours. This imbalance in the demand is exploited to provide a better service for the larger flows. The system we propose aims to increase the frequency of a service towards a city center during morning peak hours compared to a conventional system, by allowing some of the vehicles to perform express services away from the city center. For simplicity, we only consider morning peak hours, but the same system could also be applied to evening peak hours. As a result, total passenger travel time is decreased and more passengers are served especially if some vehicle capacities are considered.
