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.

FINDINGS

Results indicated that without ramp meters there was a 26 percent increase in crashes
