use defaults from national research findings, select the benefits and costs of interest, and calculate the costs and benefits of a given program.
A key strength of this model is its wide range of benefits and costs that can be selected for the analysis. The model’s flexibility and robustness allows it to be adopted by
agencies throughout the country. capabilities, and a set of working evaluation is included in the report.

Future research could seek to enhance the model to include more of the internal benefits to employers (e.g., changes in worker productivity, reduction in overhead costs, changes in employee retention, etc.). The challenge of this future enhancement is finding data relating to given TDM strategies to such business outcomes. Another area of future research would be to develop a framework to include regional or local values for some of the cost externalities and mode price elasticities for region-specific analysis.
Finally, a byproduct of this research effort that goes beyond the initial research objectives is the development of a structured approach to evaluate the impact of soft programs (i.e., programs other than changes in time or costs such as guaranteed ride home programs). Compared to the currently available soft program evaluation methods, the approach developed in this report provides a less heuristic method of estimation, resulting in statistically robust mode share impact predictions. Another future area of analysis would be the refinement of such a model to provide a standardized approach to soft program impact assessment.
