Abstract: Considering the line characteristics and actual situation of Lijiang Rail Transit Line 1, this paper studies and analyzes the control schemes of signaling systems at level crossings of modern trams. The structure, functions and interfaces of the level crossing control system and the level crossing signal equipment layout design of Line 1 are described in detail, and the whole process of trams passing through level crossings is deeply analyzed. By focusing on different types of level crossings, and through the equipment layout and interaction between tram level-crossing control system and municipal traffic control system, trams are able to pass through the level crossings safely and efficiently. This paper puts forward a solution for the scenario where there are several types of level crossings on the same tram line and explains the different processing logic for trams passing through different types of level crossings to fully guarantee the safety and operation efficiency of trams.
