Why do we need a green light to enter a freeway?
After a long hiatus, Michigan is again implementing ramp metering, which helps regulate the flow of traffic from ramps onto busy freeways. It will be used on the I-96 Flex Route portion in western Oakland County.
 On this week’s Talking Michigan Transportation podcast, Sarah Gill, operations engineer for the Michigan Department of Transportation’s (MDOT) Metro Region, talks about how it will work and the history of ramp metering in Michigan.
 Gill explains the key reasons for implementing ramp metering, which include improving merging, reducing crashes and reducing travel times. An MDOT how-to video offers guidance on the concept.
Next week’s episode will delve farther into the topic and include conversations with a traffic safety engineer with the Colorado Department of Transportation (CDOT), who will talk about how successful the concept has been in the rapidly growing Denver area. You’ll also hear a national perspective from the director of safety and mobility at the American Association of State Highway and Transportation Officials (AASHTO). |
