Many environmentalists view intelligent transportation systems (ITS) as perpetuating the status quo and accommodating the auto-dominated transportation system. This article examines the environmental viability of ITS strategies. At the core of the viability problem is that ITS strategies increase vehicle speeds, which in turn increases emissions. Nitrogen oxides (NOx) and volatile organic compounds (VOC)--the components of smog and ground level ozone--are regulated by the 1990 Clean Air Act Amendments. The legislation requires transportation plans and programs to conform to state air quality plans in nonattainment areas--mostly major metropolitan areas. The author concludes that ITS viability is more than a scientific challenge; advocates on both sides must develop strategies that balance environmental, economic, safety, and equity goals for their particular area. |
