Effectiveness of traveler information tools : final report, January 2008.

The North Carolina Department of Transportation (NCDOT) sponsored research aimed at enhancing the department’s
ability to assess the effectiveness of traveler information tools. The NCDOT has and will continue to make investments in
Intelligent Transportation Systems (ITS) that fall under the heading of Advanced Traveler Information Systems (ATIS). It
is critically important for the NCDOT to be able to assess the impacts, especially the network performance benefits, of
candidate ATIS investments in order to make well-informed project decisions and set funding priorities. This final report
documents the project’s findings, conclusions, and recommendations. The recommendations include the implementation of
an ATIS evaluation framework with DYNASMART-P as the primary integration tool and the development of a robust
ongoing data collection program to support ATIS research and evaluation.
