RAMP METERING TECHNOLOGY AND PRACTICE: TASKS 1 AND 2 SUMMARY

The primary objective of this project is to develop improved ramp metering design and implementation guidelines for use by the Texas Department of Transportation. These guidelines will provide for more effective design, implementation, and maintenance of ramp-metering systems at existing as well as proposed freeway entrance ramps. This report documents the results of Tasks 1 and 2 in the proposed work plan. The purpose of these tasks was to study current ramp-metering operations in Texas and other states. Researchers conducted several field studies as part of a review of the ramp-metering operations in Texas. This report also presents a summary of results from these field studies. Finally, this report presents a strategy to complete the remaining research.
