In this section, a selected number of cases are presented, comprising studies that evaluate different popular TDM strategies. The objective is to provide insight on how TDM impacts are being quantified by practitioners, in particular:
Evaluation Criteria – While general guidelines as provided by TDM expert publications provide a full range of benefits, practitioner experience provides additional insightful information as to what is actually measurable, given data and budgetary constraints; and,
Evaluation Methods – Practitioner work can shed some light on the most commonly used evaluation approaches, such as benefit cost, life cycle or least cost planning analyses.
As part of this section of the literature review, many reports were carefully perused. Each study that has been included in this report provides a different evaluation methodology and set of evaluation measures. Among the evaluation methods are return on investment analysis, break-even point analysis, and quantitative analysis focusing on advantages in a single sphere (e.g., travel times, air quality etc.), mathematical model evaluation and research oriented studies from Washington and Australia.
University of Washington U-Pass Program
The U-Pass program was started by the University of Washington to offer flexible transportation to its students at a low price. Research for a new Campus Master Plan conducted by the University in 1989 projected an increase in the number of students, faculty and staff with a subsequent reduction in the number of parking spaces. The University thus assembled a task force of students, faculty and staff from two local transit agencies, namely the King County Metro and the Community Transit, and developed a new Transportation Master Plan (TMP). The key element of the plan was to significantly increase the University parking rates, to discourage driving alone and also to raise funds for the implementation of the U-Pass Program. With the above views, the program was launched in September 1991.
The key element of the U-Pass program is managing the demand of SOV through product
pricing. It is programs, both encourage the participants are
an award winning program used as a model for other transportation locally and nationally. As the main idea of the U-Pass program is to students and staff to adopt alternative modes to driving alone, the provided with many incentives including:
