An investigation of smarter driving : emission and exposure modelling and micro simulation

Abstract

Promoting smarter driving may be a useful initiative to reduce the negative environmental impacts of travel in the present car dominated era. Smarter driving may include efficient driving and route choice which reduces fuel consumption, CO2 emissions (Eco-Routing) as well as personal exposure to harmful pollutants. However, efficient driving and Eco-Route choice techniques possess some practical as well as technological limitations, primarily because of the real-time nature of their application. Efficient driving that refers to controlling/limiting acceleration and speed of vehicles may have a network wide impact of increased overall network travel time. Although, many investigations of such Eco-Driving have reported potential reductions in fuel consumption and CO2 emissions ranging from 5% to 40% across various jurisdictions and initiatives, a review of the literature revealed contradictory impacts of Eco-Driving that required further investigated.
