On Estimating Vehicle Energy Consumption Using Dynamic Traffic Assignment Vehicle Trajectories

Due to increased emphasis on the importance of measuring the environmental impact from transport vehicles, there is a growing interest in calculating vehicle energy consumption and emissions on a city-wide scale. However accurate vehicle energy and emissions estimations require detailed vehicle behaviour on a timescale generally more disaggregate than obtained from dynamic traffic assignment simulations. This work discusses the challenges faced when deriving vehicle trajectories from DTA output and then proposes two methods to integrate DTA and energy consumption models. These approaches were compared on a small network and future work in verifying the analysis was discussed.
