Evaluation of TDM

Evaluation of TDM

Public Process Related to TDM

Over the course of the 2003 TMP Update process, a variety of TDM strategies and their potential implementation in Boulder were investigated. The Timeline and History serves as a highlight of the specific TDM elements developed by the staff and consultant team, outcomes of the public process, and any actions taken relative to these strategies. For more detail see the Community Involvement and each phase of the update process.

Analysis of TDM Concepts and Strategies

Strategies that encourage the use of transportation options are interrelated and supportive of one another.

The strategies are divided into five distinct sections:

  • Management and Parking
  • Facilities and Design
  • Efficiency
  • Marketing
  • Incentives

Prior to these categories of strategies, a different grouping was used during the process of selecting the strategies that would be most applicable and appropriate for Boulder. The categories of strategies included the following: Modal Promotion Strategies; Efficiency Strategies; Financial Incentives; Pricing Strategies; Facility / Land Use / Transit Oriented Development Strategies; and Implementation Options.

The documents that were the result of the analysis of the strategies during the 2003 TMP Update process are listed below:

  • Comprehensive List of Potential TDM Strategies a detailed examination of each strategy (classified into general areas of low, medium and high applications for Boulder, and their potential effectiveness), its implementation environment, general opportunities and limitations.
  • Evaluation Matrix offers an initial screening of TDM strategies for Boulder, organized in a “Consumer Reports”-like approach to evaluation. Each of the strategies are presented with general evaluation criteria, including the implementer suitability, effects upon Vehicle Miles Traveled (VMT) and Single-Occupant Vehicle (SOV) reduction (called “modal shift” potential), cost implications and effectiveness measurements, political palatability, and adoption.
  • TDM Strategies for Implementation – an overview of combining TDM strategies for implementation.
  • Overview of TDM strategies background information and a general assessment as to how packages of strategies may be combined to achieve differential expectations

Experience of Other Communities

Boulder is one of a number of cities nationwide that is looking at how to manage demand for our transportation systems because roadway expansion is not always feasible due to fiscal constraints and environmental impacts. As part of the 2003 TMP Update process, other communities were evaluated in terms of TDM.

  • Peer Review –a panel of national and local experts share their expertise on how to successfully implement TDM programs and strategies.
  • Incentive-Based Case Studies - Areas around the country have demonstrated the effectiveness of TDM. These illustrate a few that pertain to Boulder.
