Book Description

The Freeway Operations Committee (A3A09) developed 14 new research problem statements during 1979. In 1980, these statements were combined with 35 problem statements that were previously developed by the Committee and published in TRB Special Report No. 158. All 49 research problem statements were then ranked by the following process. Each member ranked the statements from highest (1) to lowest (49), and the results were averaged. After discussion of the scores at the June, 1980 meeting, the statements were reviewed by a task group of the Publications Subcommittee and with minor modifications the top 10 were selected. At the mid-year meeting in June, 1981, the Committee approved these 10 statements and recommended that they be published. The are: Effective Freeway Corridor Management; Integrated Freeway and Area Traffic Control; Freeway Corridor Improvements Analysis; Freeway Control Under Saturated Conditions; Methods for Detecting and Identifying the Character of Freeway Incidents; Selling of Ramp Metering to Local Governments; Utilization of Digitalized Video Information for Incident Detection; Scheduling Freeway Maintenance Activities; and The Use of Highway Advisory Radio Versus Variable Message Signs.
