AIR QUALITY IMPACTS OF TRANSIT IMPROVEMENT, PREFERENTIAL LANE, AND CARPOOL/VANPOOL PROGRAMS

The report has been prepared in accordance with Section 108(f) of the Clean Air Act, as amended, August 1977. It is intended to assist urban areas in developing State Implementation Plans and integrating their transportation system management and air quality planning programs as required by FHWA, UMTA, and EPA. The report analyzes the air quality, travel, energy consumption, economic, and cost impacts of three types of transportation programs: priority treatment for high occupancy vehicles on freeways and arterials; areawide carpool and vanpool programs; and transit fare reductions and service improvements. Important factors (e.g., meteorological conditions, traffic volumes and speeds and changes in modal choice) likely to influence air quality and emissions for the above programs are also analyzed.
