MODELLING THE ENVIRONMENTAL BENEFITS OF ITS USING POWER-BASED VEHICLE EMISSIONS MODELS.

This paper demonstrates the feasibility of using power-based vehicle emissions models to evaluate the environmental benefits of ITS. An incident management strategy that can reduce the duration of an incident blocking alllanes from 30 to 15 minutes was found to have the potential to provide 22percent reduction in fuel consumption rate and 20 percent reduction in CO2. The provision of real-time travel information was also tested. The results suggest that the implementation of a VMS route guidance strategy has potential to reduce fuel consumption by 9.2 percent, CO emissions by 1.4 percent and CO2 emissions by 8.7 percent.
