Book Description

Pursuant to a congressional request, GAO reviewed federal efforts to promote more efficient transportation management systems and the extent to which air quality concerns affected transportation systems management (TSM) activities. GAO found that: (1) 96 percent of all metropolitan planning organizations planned TSM activities for their regions; (2) organizations placed more emphasis on supply than demand; (3) when organizations planned demand management activities, the greatest emphasis came from areas with a population of 1 million or more; (4) planning alone failed to ensure implementation of demand management activities because of the lack of consensus among implementors, and the absence of a link between planning and funding; (5) only 26 percent of all metropolitan planning organizations indicated that their short-term plans included some demand management or related activities for air pollution reduction; and (6) the planning and implementation of demand management or related activities for air quality improvement required the involvement of many agencies.
