A method of real-road simulations of heavy duty vehicle performance 2020-01-0370

Traffic and vehicle simulations are developed individually, however, vehicle performance optimization is one of the main targets of traffic management. Joint simulations of traffic and vehicle under real-road situations can reflect the semi-real-world performance of vehicles, with real road situations and traffic conditions being taken into considerations. This paper proposed a approach, which combined the traffic and vehicle simulations that were realized by SUMO and GT-Suite software, respectively. In the simulation, the real-road conditions were used, such as the road elevation and rolling resistance factor, hence, the simulation results were much more close to the real-road driving. The process of the real-road vehicle simulation is as following: 1) obtain the 2D real-road network; 2) integrate the road elevation into the 2D real-road network; 3) extract the targeted route for further simulation; 4) load the real-road network and traffic information into SUMO software; 5) input the traffic simulation results into GT-Suite software to finish the vehicle simulation. It should be noted that in the 3rd step, the crossways of other roads and the target one were remained and there was traffic flow as well.
