Abstract

Abstract: In this paper, a system simulation method is established to simulate urban rail transit operation in the event of an emergency. Based on the actual data of Beijing Subway Yizhuang Line, we developed a simulation software by using discrete event model, Processing and G4P library. Functions include overspeed protection, train speed authorization generation, train movement control and train station control are realized. We simulated and evaluated the running scenarios of multiple-train operation on a single urban rail line and its delay conditions in an emergency event. Results showed that urban rail transit had different delay consequences when an emergency event happened at different positions or different time intervals; furthermore, those delay consequences could be relieved effectively through different operation adjustments like changing train departure and dwelling intervals.

Key words: urban rail transit, emergency event, train operation, system simulation, delay evaluation
