Incremental Transition to Electric Transit Systems: Evaluation, Planning, and Operations

项目名称：	Incremental Transition to Electric Transit Systems: Evaluation, Planning, and Operations
摘要：	The advent of automotive technology, such as vehicle automation and electrification, is transforming transportation systems. While electric passenger vehicles have found their ways to the market, larger vehicles such as buses and trucks are still in their early stages of adoption. At the same time, environmental issues due to greenhouse gas (GHG) emissions necessitate cleaner energy sources to replace fossil fuels. California has mandated the electrification of all transit systems by a 2040, and many transit agencies in the country began pilot testing of battery-electric buses (BEBs). Primary challenges in adopting BEBs for transit service are (1) planning for incremental transition to electric fleets and infrastructures, and (2) developing charging strategies to deal with the operational limitations of BEBs under uncertain conditions. This study aims to develop a practical and realistic plan to utilize existing charging infrastructures and the current transit network layout to facilitate the transition to an electric transit system through an incremental deployment plan. The research team will use geographic information systems (GIS) to collect and manage spatial data from various sources, visualize route characteristics and existing charging facilities, and perform spatial-temporal analysis to identify candidate transit routes for electrification. The team will then develop multi-stage stochastic programming models to select the routes that, by electrification, provide the highest net benefits to the environment and society. A comprehensive set of benefits (for operators, users and, society), costs (capital and operating), and operational constraints (frequent charging needs, uncertain energy consumption, etc.) will be considered. The model will produce long-term infrastructure and fleet replacement plans, such as routes for electrification and charging stations to be used, and strategies for short-term decisions, such as bus scheduling or dispatching, compatible with the long-term plans.
