Dynamic Bus Dispatching Method Based on Mixed Control Strategy

In-service buses are susceptible to stochastic factors, specifically bus bunching, which can introduce unreliability. To address the ongoing bus bunching problem, we propose a comprehensive control strategy that incorporates speed guidance, intersection signal adjustments, and cooperative overtaking. A dynamic dispatching model based on the strategy is developed, with the objective function considering headway irregularity, the total travel time of passengers, and delay of the private vehicle. The model is solved using a genetic algorithm. In this paper, we conduct numerical experiments and compare the performance of the proposed strategy with the uncontrolled strategy. The results demonstrate that the proposed strategy can not only ensure the stability, but also improve the efficiency of the bus, thereby validating the performance of this method.
