Guensler, Randall L., Pamela Burmich, Anne B. Geraghty (1992) The Role of Transportation Control Measures in California's Air Pollution Control Strategy. Institute of Transportation Studies, University of California, Davis, Research Report UCD-ITS-RR-92-11
In this paper, the emission reduction benefits of California's new low-emission vehicles and clean fuels program are reviewed. The air quality management plans of three major metropolitan areas in California are examined, to identify emission reductions needed to meet federal and state air quality standards. For each of these three areas, emission reductions expected from transportation control measure implementation are presented. Then, the extent to which the reductions are "significant" and relied upon in each of the local attainment efforts is analyzed.
The emission reductions expected from the stringent exhaust emission standards of California's new low-emission vehicles and clean fuels program will not be sufficient to meet mandated clean air standards in the study areas. Based upon our review, transporation control measures appear to be necessary components of the air quality management plans in California's major metropolitan areas. The paper concludes that cost-effective transportation control measures (TCMs) will be needed as a complementary strategy to California's stringent tail-pipe standards in moderate to extreme non-attainment areas.
