Novel C ITS support for electric buses with opportunity charging
Electric buses with opportunity (on route) charging are one of the emerging types of "clean" buses. However, the technology brings new challenges as battery related requirements might interfere with the revenue service operator's primary concern. The emerging Cooperative Intelligent Transportation Systems (C ITS) paradigm holds promise to provide an effective support to e bus based operations and replace older ITS methods designed for buses with internal combustion engines. In this paper we demonstrate how charging operations can be supported with a novel type of Green Light Optimal Dwell Time Advisory (GLODTA) system dedicated to electric buses. It not only can support on route battery charging so that charging operations are integrated into schedule constraints but it can also replace existing holding strategies used to regulate punctuality of bus services. A simulations based analysis shows that system performance is positively correlated with maximum additional dwell time available to a bus and negatively correlated with cycle length of traffic signals.
