Research Projects

This study was completed by Systems Applications and K. T. Analytics for the California Air Resources Board (ARE) to develop methodologies for analyzing travel and emission changes resulting from individual transportation control measures (TCMS) and TCM packages. The work establishes new conceptual and analytical methodologies useful for transportation and air quality planners who must evaluate TCMs as part of air quality attainment plans. Four major steps were conducted as part of this project: (1) a brief literature review and conceptual discussion linking specific TCMs to travel and emission changes; (2) development of a conceptual framework for analyzing TCMS, (3) creation of quantitative methodologies to evaluate specific measures and measure packages; and (4) application of the methodologies to a sample area to demonstrate their use. Support to conduct this work was provided by the Analysis Section of the Air Resources Board's Mobile Source Division.
