summary was the Texas Transportation Institute (TTI) ramp meter study titled “Ramp Metering in Minnesota” by Lomax and Schrank (1). In addition, two cities (Seattle, Washington and Phoenix, Arizona) were interviewed to obtain more detailed insight into the objectives, strategies, successes, and issues with their ramp metering systems.
