This research proposes to develop an advanced Eco-Cooperative Adaptive Cruise Control System (Eco-CACC) for hybrid electric vehicles (HEVs) to pass signalized intersections with energy-optimized speed profiles, with the consideration of impacts by multiple signalized intersections. The proposed research extends the Eco-CACC system previously developed by the research team on conventional internal combustion engine (ICE) vehicles to HEVs. The proposed HEV Eco-CACC system will include two modes - automated and manual modes for vehicles with or without an automated control system. The proposed research will start by developing a general HEV energy consumption model which can be easily calibrated and used in the Eco-CACC system to compute energy consumption by using instantaneous speed data. By using the proposed HEV model, the team will develop a base HEV Eco-CACC system by considering a single signalized intersection. Thereafter, an advanced HEV Eco-CACC system will be developed by considering the impacts of multi-intersections. The automated mode of HEV Eco-CACC system will be implemented into the microscopic traffic simulation software to validate the system-wide impacts of traffic mobility, energy consumption and emission under different levels of market penetration rates, traffic conditions, signal timings and vehicle types. Lastly, the manual mode HEV Eco-CACC will be tested by participants using driving simulators at MSU to compare the proposed Eco-CACC system with two other scenarios – uninformed drive and informed drive provided with signal time counting down information. It is anticipated that the proposed system will improve the mobility of HEVs by reducing delays, energy consumption and emissions while traversing signalized intersections. |
