A computer-implemented method includes establishing a road network model on which a plurality of simulated vehicles may be run. The method also includes setting up a plurality of scenarios under which vehicle driving conditions vary to be run on the road network model. The illustrative method includes receiving energy usage related data for a plurality of simulated vehicles run in at least one of the plurality of scenarios on the road network model. The method further includes calculating a total energy consumption for each of the vehicles. The method additionally includes repeating the receiving and calculating steps to determine how various elements of the road network model and scenarios effect vehicle energy consumption.
