Abstract
Reducing the volatility in the operation of public transport is still an important consideration when seeking to maintain efficient and stable operations. In this study, stations and intersections are considered as a whole, and a self-coordinated holding strategy is developed based on the fluctuation of passenger flows and the characteristics of signals during off-peak periods. On this basis, a collaborative optimization is carried out in combination with signal priority and speed control. The mathematical model is established with the goal of minimizing passenger travel and enterprise operation costs. A section of the K2 line in Ganzhou City is selected for a case study. The improved discrete binary particle swarm optimization algorithm (DPSO) is then used for the calculations. The simulation and comparison of the arrival time distribution, headway deviation, and travel time index before and after the optimization show that reliability, stability, and efficiency have been improved by the optimization, which verifies the effectiveness of the optimization method.
