Optimization of Signalized Intersections Equipped with LRV Signal Priority Systems by Minimizing Cars' Stop Time
Paper i proceeding, 2019

There are some strategies suggested to improve the performance of intersections and increase the demand for public vehicles by providing them priority. In order to achieve this goal, several policies have been used such as Transit Signal Priority (TSP) system for Light Rail Vehicle (LRV). LRV signal priority is a timing strategy that gives priority to LRVs at signalized intersections. More specifically, this strategy is based on changing the sequence of phases, extending green time and reducing red time of LRV's phase. Although this method has considerable benefits for LRVs, it penalizes private vehicles by increasing their delay and stop time at intersections. This paper aims to propose a model to improve LRV signal priority systems. The modifying model for LRV signal priority systems minimizes the green extension and red reduction of LRV's phase by using linear programming (LP) method to calculate an optimal speed for LRVs reaching the stop line. Consequently, LRVs are prioritized while the performance of private vehicles would be improved.
