Abstract

Public transportation networks play a crucial role in urban mobility by providing efficient, reliable, and sustainable transport options. One of the main challenges in bus network operations is minimizing passenger inconvenience by improving service connectivity and thus, minimizing waiting times. Timetable synchronization seeks to optimize the timing of bus arrivals at transfer nodes, ensuring minimal waiting times for passengers transferring between routes. This is particularly important in multi-modal transport networks, where seamless connections between different transport modes significantly influence passenger satisfaction. This study builds on the bus timetable resynchronization problem and expands it by introducing the concept of generalized passenger travel times, which reflects how increased in-vehicle passenger load leads to longer perceived passenger travel times. Given these considerations, this study introduces the bus timetable resynchronization problem (BTRP) with perceived travel times and models it as a nonlinear programming problem. BTRP is then reformulated as a MILP through the use of linearizations, and is solved to global optimality using Branch-and-Cut. Computational experiments have been performed demonstrating the impact of the in-vehicle load on the perceived passenger travel times and the synchronization of services.
