===Minneapolis–Saint Paul ramp meter experiment===
{{more citations needed|section|date=July 2020}}

In 2000, a $650,000 experiment was mandated by the Minnesota State Legislature in response to citizen complaints and the efforts of State Senator [[Dick Day]]. The study involved shutting off all 433 ramp meters in the Minneapolis-St. Paul area for eight weeks to test their effectiveness. The study was conducted by [[Cambridge Systematics]] and concluded that when the ramp meters were turned off freeway capacity decreased by 9%, travel times increased by 22%, freeway speeds dropped by 7% and crashes increased by 26%.<ref>{{Cite web |title=Study Results - Ramp Meters - MnDOT |url=https://www.dot.state.mn.us/rampmeter/study.html |access-date=2025-03-25 |website=www.dot.state.mn.us}}</ref> However, ramp meters remain controversial, and the [[Minnesota]] State Department of Transportation has developed new ramp control strategies. Fewer meters are activated during the course of a normal day than prior to the 2000 study, some meters have been removed, timing has been altered so that no driver waits more than four minutes in ramp queue, and vehicles are not allowed to back up onto city streets.
