Abstract

Mandar Khanal

Ramp metering is a proven, effective measure to deal with congestion and accidents. The most comprehensive study ever conducted on ramp metering was published in 2001 and evaluated their effectiveness by turning off the meters in the Minneapolis-St. Paul area . Without meters, freeway travel times increased 22% resulting in 2.6 million hours of unexpected delay.
