What Have We Learned About ITS?
Summary Information
The U.S. Department of Transportation study "What Have We Learned About ITS?" is a synthesis of the national experience with implementing ITS through the year 2000, with a goal of more effectively planning the future of the National ITS Program. This synthesis examines which ITS technologies and applications have been successful, which have not, and those for which more information is needed to make a judgment. The seven areas included within the scope of this study are as follows:
- Freeway, Incident, and Emergency Management, and Electronic Toll Collection (ETC)
- Arterial Management
- Traveler Information Systems
- Advanced Public Transportation Systems
- Commercial Vehicle Operations (CVO)
- Cross-Cutting Technical Issues
- Cross-Cutting Institutional Issues
Adaptive signal control may also lower operations and maintenance costs associated with traffic signal retiming. Minnesota DOT signal technicians found that an adaptive signal control system was easy to operate and required minimal maintenance.
