| description | [Objective] To address the tram issues of needing speed deceleration at grade crossings, a vehicle-road cooperative speed control system for trams passing at grade crossings is proposed. [Method] The operational characteristics of tram at grade crossings are analyzed. The design concept of the vehicle-road cooperative speed control system for trams passing at grade crossings is introduced, along with the realization process of logic algorithm module. The implementation effects of the proposed control system are analyzed. [Result & Conclusion] The proposed control system uses vehicle positioning technology and clearance area conflict detection technology, combining communication with the intersection traffic signal to determine the method of tram passing through the crossing. When the tram obtains the right of way and the clearance area has no conflicts, a controllable physical isolation facility is temporarily adopted to create an exclusive closed interval for the tram, ensuring efficient and safe passage at the grade crossing. The proposed control system can realize tram passing intersection under green light condition without deceleration, and is well suited for non-platform grade crossings with a distance of over 250 meters between the front and rear platforms, as it can increase operating speed by approximately 15% and reduce interval operating energy consumption by 40%, while also reducing random deviations in inter-station travel time caused by grade crossing interference. |
