| 摘要： | Two premier sketch-planning tools used to evaluate transportation control measures (TCMs)--the San Diego Association of Governments (SANDAG) TCM tools method and the Systems Applications International (SAI) method--are examined. A critical analysis and sensitivity analysis were performed on the SANDAG and SAI methods. Data collected for the El Paso, Texas, nonattainment area were used to evaluate the sensitivity results. The sensitivity analysis examined several variables in five TCMs: flextime, ridesharing, transit fare decrease, transit service increase, and parking management. Results of the sensitivity analysis showed that the tools are most sensitive to the TCM project descriptors and work-related variables. The report concludes that (a) recent work in the field has advanced the state of the practice and (b) although sketch-planning tools are gross estimating techniques, they are currently the best TCM analysis tools. Areas identified for improvement include (a) developing procedures for estimating TCM participation rates; (b) developing indirect trip effects and latent demand estimation procedures; (c) evaluating synergistic, additive, and negative effects of TCM programs; and (d) incorporating modal emission analysis. |
