The adaptive traffic signal control system, as well as the Transit Signal Priority (TSP) concept has both been viewed as important opportunities for reducing overall traffic congestions and improving bus transit services. However, few studies were conducted on combining them together. A dynamic signal timing optimization model was developed in this research, which aims at reallocating green tim...

tem, the signal returns to a background cycle (2). For example, in many applications priority requests are simply inhibited for a certain number of cycles or minutes after a priority interruption so as to ensure that other phases recover. This kind of blunt strategy limits the potential effectiveness of signal priority. Further complicating matters, buses turning into and out of a terminal tend...

This article presents a process to define the framework for an advanced Transit Signal Priority (TSP) algorithm. For this study, traffic and transit agencies from a broad range of municipalities in Ontario, Canada, provided their views and expertise on various TSP-related issues, including practical needs, design implementation, performance measures, and challenges in developing effective TSP c...

Integrating fixed and mobile roadway data 2 ABSTRACT Fixed-site and mobile data sources have distinct strengths for representing roadway conditions, and unique insights can be generated by combining the two. Ongoing research on an urban arterial roadway corridor combines distinct data sources for multi-criteria transportation facility performance assessment. The roadway is instrumented with an ...

Keeping the density of traffic flow and air pollution in an acceptable level and developing a good capacity for transit in the high priority areas of the city, is really a big deal in large and crowded cities. To address this problem, a new method of intersection signal optimization is presented in this paper. Based on network fundamental diagrams, an Internal–External Traffic Metering Strategy...

This paper presents a traffic responsive signal control system that optimizes signal settings based on minimization of person delay on arterials. The system’s underlying mixed integer linear program minimizes person delay by explicitly accounting for the passenger occupancy of autos and transit vehicles. This way it can provide signal priority to transit vehicles in an efficient way even when t...
