Twin Cities Ramp Meter Evaluation
Summary Information
A Minnesota Department of Transportation (Mn/DOT) study revealed the impacts of shutting down an extensive ramp metering system on Minneapolis-St. Paul area freeways for a 6-week evaluation period. The study analyzed data collected from four test corridors chosen to represent typical freeway configurations and conditions across the region. The study collected a variety of data using several data collection techniques, including probe vehicles operated during peak periods, traffic volume counts from existing traffic detectors and temporary installations, crash statistics, and traveler surveys.
