Signal Control Optimization for Bus Transit based on Simulation of Urban Mobility

Bus transit has been played an important role in the sustainable communities, leading to an environmentally friendly and economical mode of transportation. However, with uncomfortableness such as long time travel and unpunctual schedules, the public prefer driving themselves instead of taking buses. Schedule delay is of great importance for buses. With punctual buses schedule, bus transit can be a reliable way for people into consideration. The transit signal priority (TSP) can provide the signal priority for buses to get through the signalized intersections easily, reducing random delay. As for different buses within the same intersection, the cobalt controller can adjust appropriate signal timing by dividing them into different levels of priorities with effectiveness, allocating the most delayed buses with the highest level of priority and so on. In this project, the research team implement TSP strategies into Simulation of Urban Mobility (SUMO), building up an intersection or with different coming buses, using (V2I) communication models with the signal controller in complex scenarios to reduce delays for each bus with different priorities. The most important part of this project is to adjust the cobalt controller logic into VENTOS, a vehicular network open simulator to combine the signal controls with TSP strategies. Once the research team implements the combined two of them, the test could be conducted under one or multiple intersections with buses. In the beginning, the team will conduct a simple test with one bus in an intersection to demonstrate this project works well and then take complex scenarios into considerations.The team divides this project in following parts: (1) Construct a complex scenario of intersections in SUMO; (2) Using hardware in the loop strategy to adjust the controller logic into VENTOS; (3) Simulate the real-world transportation with delayed buses; (4) Conduct a test to demonstrate the effectiveness of the signal control optimization.
