Abstract

To address the lack of speed regulation mechanism and the high dispersion of operational time in the current manual driving mode, this paper proposes an automatic speed guidance method for trams at intersections. Considering the speed disturbances caused by potential traffic conflicts at intersections, an initial decision point for safe passage speed at an intersection is established, dividing the operational curve into deterministic segments and disturbance-response segments.To verify the effectiveness of the method, a case study of Songjiang Tram Line 1 is conducted.Driving simulation experiments are performed to obtain manual driving trajectories, and a dynamic trajectory simulation model incorporating both manual driving and automatic speed guidance at intersections is developed. Evaluation is carried out under the two scenarios of free driving and stochastic signals. The experimental results show that the method enhances vehicle speed performance, absorbs operational delays, and reduces intersection stops. It significantly outperforms manual driving in terms of travel speed, time reliability, and energy efficiency. It achieves greater operational benefits on green wave-coordinated routes.
