This paper investigates the system-wide impacts of using eco-routing within two large metropolitan networks (i.e., Cleveland downtown and Columbus downtown). The INTEGRATION software is utilized to evaluate various eco-routing strategies. The simulation results demonstrate that the eco-routed vehicles do not always save fuel consumption when compared to the standard user equilibrium. In particular, the fuel savings of eco-routing are sensitive to the network configuration, the congestion levels, and the market penetration of eco-routing vehicles. Furthermore, eco-routing does not necessarily reduce vehicle travel distance or travel time. The simulation results indicate that when the eco-routing reduces fuel consumption levels it also tends to reduce both travel distance and travel time when compared to the standard user-equilibrium routing. The simulation results show that in general when the market penetration of eco-routing vehicles is 90 and 100 percent the total system-wide fuel consumption is minimized in most cases. Furthermore, for this specific case study the user-equilibrium routing scenario does not produce the highest fuel consumption level. Instead, a market penetration of 20 percent eco-routers appears to produce the highest fuel consumption levels.
