Energy-efficient train timetable optimization for tram system under multi-signal priority strategies.

ABSTRACT: Energy-efficient operation is an effective approach for diminishing the operational expenses and carbon emissions of the tram system. Tram operation strategies and signal priority play a vital role in energy-efficient train timetable optimization. However, the impact of trams on road traffic efficiency has limited consideration in traditional optimization methods. This paper develops a bi-objective mixed-integer linear programming (MILP) model incorporating multi-signal priority strategies (e.g., active signal priority strategy, no-signal priority strategy) and road traffic flow to obtain an energy-saving operation scheme. First, the signal priority strategy that trams should adopt based on the intersection traffic flow is determined to improve road traffic efficiency. Second, the speed pr
