Abstract:

This report presents evaluation results from the Subject Stated Response portion (Part I) of the Natural Use Study of the DIRECT (Driver Information Radio using Experimental Communication Technologies) operational test sponsored by the Michigan Department of Transportation in conjunction with the Federal Highway Administration. DIRECT focused on simultaneous testing of four low-cost voice-based traffic information delivery systems that have a high potential for operational deployment: automatic highway advisory radio (AHAR), low power highway advisory radio (LPHAR); telephone. and Radio Data System in conjunction with a “Subsidiary Communications Authority” subcarrier (RDS/SCA).

The study addressed three evaluation questions regarding the aforementioned route-specific traffic information systems: 1) What do people think about the tested systems? 2) How do people behave in response to the tested systems? 3) How do choices induced by the systems affect trip characteristics? The focus of the effort was comparison of subject response to the various systems, and not comparison of subject response to various formats of traffic report messages. Thus, a standard format for messages was chosen prior to the study and the traffic message corresponding to each incident was fed in parallel to each of the systems.
