Montgomery County, MD

Montgomery County, Maryland, is located just outside Washington, DC. This urban county is home to many regular commuters into Washington, DC. A four-section vertical all-arrows display was used. The flashing yellow arrow indication was tied to the opposing through green indication. The County used Econolite NEMA controllers for local intersection management and implementation required special external logic. The County did not issue a media press release prior to implementation but did use variable message signs in advance of the intersections for a period of 48 hours. The County has had minimal citizen feedback during the more than two years of deployment.
