Article: Designing a simulation framework to develop and evaluate an eco-routing strategy Journal: International Journal of Vehicle Design (IJVD) 2024 Vol.95 No.3/4 pp.275 - 290 Abstract: This paper uses a novel simulation framework to develop and evaluate an eco-routing strategy that aims to optimise the vehicle route. The simulation framework consists of three blocks: A microscopic traffic model simulates various traffic scenarios; a traffic management centre is responsible for processing transient traffic data; and analytical powertrain models represent longitudinal dynamics of real vehicles. The route optimisation is formulated as a constrained optimisation problem and solved by the new open-source software OR-Tools. In addition, the effectiveness of the eco-routing strategy is evaluated based on three vehicle types. Vehicle trajectories on different roadways are quantified by key performance indicators to understand how the eco-route reduces energy demand compared with alternative routes. According to the network-wide simulation results, the average energy-saving effect of the eco-route compared to the fast-route is 10.35%, while the effect is smaller compared to the short-route with an energy saving of 5.01%.

Abstract: This paper uses a novel simulation framework to develop and evaluate an eco-routing strategy that aims to optimise the vehicle route. The simulation framework consists of three blocks: A microscopic traffic model simulates various traffic scenarios; a traffic management centre is responsible for processing transient traffic data; and analytical powertrain models represent longitudinal dynamics of real vehicles. The route optimisation is formulated as a constrained optimisation problem and solved by the new open-source software OR-Tools. In addition, the effectiveness of the eco-routing strategy is evaluated based on three vehicle types. Vehicle trajectories on different roadways are quantified by key performance indicators to understand how the eco-route reduces energy demand compared with alternative routes. According to the network-wide simulation results, the average energy-saving effect of the eco-route compared to the fast-route is 10.35%, while the effect is smaller compared to the short-route with an energy saving of 5.01%.
