| Abstract | ||||
| Promoting public transit can be done at a reasonable cost using the tram system. However, the system's steady operation depends on the delay at signalized junctions. Transit signal priority (TSP) control has been investigated as a way to enhance system performance. To address this challenging issue, our work concentrates on passive TSP control for the Tram system. To minimize per capita delay, an optimization model is developed to coordinate signal offsets along the Tram Line's arteries. The results of our case study on the tram route in Alexandria, Egypt, suggest that passive TSP control could give trams priority while little affecting other traffic. Using a meta-heuristic algorithm and a genetic algorithm, we present a unique passive signal priority with average per-vehicle delay minimization as a goal. The mathematical optimization model is developed based on the Highway Capacity Manual (HCM2000). For the resultant optimal TSP, a set of restrictions has been established to indicate effectiveness and security. We compare the resulting cycle length and phasing timing in each junction using the "Pattern search algorithm," another effective optimization methodology, to show the effectiveness of the suggested approach. The results show that the objective function of the genetic algorithm and the pattern search algorithm is pretty much identical, also the tram headway, cycle lengths, and green time for each phase of the signalized intersection along the tram line will be presented in the study | ||||
