Overview
The purpose of this primer is to introduce and define the ATM and TDM concepts and show the need for and benefits of integrating the concepts into efforts to address congestion on the most affected facilities. The primer provides a conceptual framework, originally suggested by the Dutch Ministry of Transport, for understanding the difference between traffic management and travel demand management. The primer underscores the need to integrate the two concepts into a holistic approach to congestion management. This primer focuses more on the conceptual foundation and need for integration than on examples of how and where the integrated approach has been tested. The examples are illustrations of the linkages between TDM and ATM.
The primer describes five types of ATM and TDM integration and provides examples of each, drawn from the United States and Europe. The following are the five types of integration:
- New partnerships for integrating ATM and TDM
- Enhanced travel alternatives in actively managed corridors
- Incentives to reduce traffic volumes on congested facilities
- Real-time, multimodal traveler information to induce In-route mode shift
- Promotion of TDM at major trip generators in ATM corridors
Finally, an overall approach for integrating the two concepts is provided. It includes an overview of the integrated demand management under development in the United Kingdom.
