Mobility Assessment Report

The latest Mobility Assessment Report (pdf, 19MB) is now available. The 2014 Mobility Assessment  Report (MAR) was presented to the Planning Board on April 17. The presentation can be seen here. Montgomery County's traffic congestion has been stabilizing over the past two reporting periods from 2009-2011 and from 2011-2013 according to the 2014 MAR, a biennial study by county transportation planners that monitors local transportation trends.

Countywide Transit Corridors

Bus Rapid Transit Study Map Planners are working on a functional plan on countywide transit corridors to improve accessibility and mobility throughout Montgomery County. The transit corridors study recommends corridors for inclusion in the Master Plan of Highways, based on projected ridership, as well as identifying right-of-way needs.

MidCounty Highway The Midcounty Highway (M-83) was first included in Montgomery County’s Master Plan of Highways in the 1960s and is planned to extend from Ridge Road (MD 27) in Clarksburg to Redland Road in Derwood as an 8.7-mile, controlled access, four to six-lane major highway. Over the years, a three mile segment of Midcounty Highway was constructed, between Shady Grove Road and Montgomery Village Avenue. On November 21, 2013, following publication of MCDOT’s May 2013 Draft Environmental Effects Report, the Planning Board received a briefing by MNCPPC staff and Department of Transportation staff and heard  public testimony.  As a result of the November 21, 2013 briefing and testimony, the Planning Board issued a letter to MCDOT supporting Alternative 9A, the Master Plan Alignment. Additional information on this project is available on the MCDOT project website.

Intersection Analysis Application

Intersection Application MapPlanners have posted an interactive, user-friendly intersection analysis for anyone interested in countywide intersection traffic counts, and critical lane volumes.

Corridor Cities Transitway

State transportation officials are studying a new transit line — the Corridor Cities Transitway (CCT) — that would extend from the Shady Grove Metrorail Station to Clarksburg. The CCT could become bus or light rail service serving the I-270 corridor. Planners, who see the CCT as a lynchpin for community plans in Germantown and Gaithersburg West, use the CCT station as focal points for clustering houses, jobs, and retail near transit to support uptown activity centers and lessen reliance on automobiles.

Subdivision Staging Policy

Montgomery County’s Subdivision Staging Policy guides the timing of development and the provision of adequate public services. The policy implements a 1973 law, the Adequate Public Facilities Ordinance, that directs development to areas where public services are in place. The Planning Board helps ensure basic amenities like roads, transit and schools  for current and future residents through the Subdivision Staging Policy, which guides matches growth to the availability of public services.
