In June, 1977 the Federal Highway Administration (FHWA) and Mn/DOT signed a Memorandum of Understanding agreeing Eo cooperate in a demonstration of the use of highway advisory radio (HAR) as a part of the I-35W traffic management system. FHWA agreed to furnish the major system components and provide technical Information and consultation to Mn/DOT, and Mn/DOT agreed to install, operate and evaluate the system. This work was accomplished under the terms of the Minnesota Basic Agreement (DOT-FH-ll-8565) as Task Order No. 5, The system was developed on a 1.26 mile (2.03 Km) section of I-35W in Richfield, and became operational in December, 1977.

The purpose of this report is to present detailed information on the HAR system, and to document the results of the evaluation study.
