The bus system, a sustainable transportation mode, has changed little over the past few decades. The emerging technology of connected autonomous vehicles (CAV) has vast implications for bus network design and operations. Currently, transit agencies typically shy away from running buses more frequently in lower density neighborhoods because there would not be very many riders per trip. By making operating vehicles cheaper, transit agencies can potentially run higher frequency, lower capacity vehicles through lower density areas to help resolve the last mile problem.
In this research, the research team seeks to understand the bottlenecks facing the current form of bus operations, and explore how CAV technology, particularly smaller CAVs that can form bus platoons, can be used to design and operate bus systems that provide large and reliable service capacity to trunk lines while offering flexible last-mile service to branching service areas. The team will propose novel models for route selection, dispatching, and speed control of all buses in a bus network, and assess the performance of such models as compared to conventional bus system operations. The team will work closely with local transit agencies, such as Unitrans in Davis and Regional Transit in Sacramento, during model development and share with them the research results to facilitate their transit system planning that aims to take full advantage of CAV technology. |
