Abstract
This article is on the purpose of developing an isolated tram signal priority control strategy based on logic rule for modern tram system. The designed method is presented with features that can ensure the intersection operates in a proper manner on the premise of tram priority and avoid vehicle queue overflow when the tram passes. In this study, the new method description consists of two parts: (1) the detector locations are determined, which include the upstream detector, the upstream trigger detector, the downstream detector, and the queuing detector upon entry approach to the intersection; (2) the corresponding priority logical algorithm for signal control is designed. The proposed method is experimentally examined in a tram intersection in Huaian city, China. In the process of the experiment, the detector layout scheme and optimal priority control model are simulated and verified using the VisVAP module of the Vissim simulation software. In the experimental results, the designed scheme significantly decreases average delay than the fixed timing signal control method, while it also can prevent the vehicle queue from overflowing compared to the absolute priority actuated control scheme.
Highlights
A modern tram is a form of public transportation based on the traditional tram
The tram priority signal control system should be implemented according to local conditions, especially concerning intersections with limited road resources
We studied the situation in which the main line direction of an intersection is different from the direction of a modern tram
Summary
A modern tram is a form of public transportation based on the traditional tram. This updated transportation mode offers more transportation capability and improved effects in terms of environmental protection and energy saving. These techniques are widely used in both bus and tram systems; especially the newest edition of SCOOT, which focused on public traffic development.[8] In Germany, as a rule, the signal lights of a tram are separated from those for general vehicles This ‘‘separation’’ includes two types: one type is in the form of a distinct signal lamp that aims to reduce the number of traffic accidents caused by reading incorrect signals, and the other type is the use of various built-in parameters of signal lights, such as the green time.[9] some cities provide a green wave for the public transport modes, such as Portland in America. To evaluate the performance of the program, the VisVAP module of Vissim simulation software is used together with the field data from an intersection in the city of Huaian
