The Keys to Go Green: Looking to ITS For a Cleaner Future

This article presents an update on Intelligent Transportation Systems (ITS) technologies that can reduce greenhouse gas emissions and other pollutants by smoothing traffic flow, providing better route guidance to shorten trips, and altering driver behavior by enhancing alternatives to the single-occupant vehicle. Technologies that smooth traffic flow include traffic information that is linked to dynamic route-guidance systems. This could be extended to vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) systems when they mature. Another technology is Advanced Driver Assistance Systems (ADAS), which include blind spot and lane-departure warning devices. However, much remains to be done in refining their accuracy and acceptance before they can contribute significant gains. Some non-networked technologies such as adaptive cruise control (ACC) and intelligent speed adaptation (ISA) can improve operations by smoothing acceleration and deceleration. Electronic toll collection (ETC) is a large contributor to smoother flow. Changing behavior could be achieved by congestion pricing, which would distribute traffic across more hours of the day or persuade some drivers to use alternatives. A chart shows the environmental benefits of different ITS technologies.
