Planners Highlight Montgomery County’s Most Congested Roadways, Document Increased Transit Use in Traffic Trends Report

SILVER SPRING – In a report that provides a snapshot of just how long it takes commuters and others to traverse Montgomery County roadways, county transportation planners have ranked the top 10 most congested intersections and roads as the basis for improvements to the local network.

The Highway Mobility Report provides background to local policymakers like County Council members as they weigh funding priorities to improve area transportation networks. The Planning Board uses the report to make decisions about lane, intersection or crosswalk improvements while reviewing development applications.

It should come as no surprise to county motorists that most congestion occurs along busy north-south corridors Rockville Pike, Connecticut Avenue, Georgia Avenue and Colesville Road and east-west connectors like Veirs Mill Road and MD 28. Planners labeled the intersection of Shady Grove Road and Midcounty Highway as the most congested, followed closely by Rockville Pike at West Cedar Lane.

Transportation planners calculate congestion by counting cars and determining average traffic volume in each lane at peak morning and afternoon commuting periods.

In a departure from previous studies, this year’s Highway Mobility Report, which goes to the Planning Board on Monday, analyzes transit use and pedestrian activity to provide a more holistic view of travel in the county. Reflecting national trends, planners found a 5 percent increase in Metrorail ridership between February 2006 and February 2009. Metrorail ridership was highest at those stations located amid a mix of houses and businesses, such as Silver Spring.

Residents also frequent the county Ride On buses, with heaviest ridership –about 8,000 bus passengers daily – on routes running from Silver Spring to Germantown along the I-270 corridor, and among down-county commercial centers. Ridership in 2008 exceeded the number of passengers – measured by daily average boardings – using Metrorail, demonstrating the importance of Ride On buses to how people get around.

For those who travel by car, the report offers some cause for hope. Two projects now under construction will improve highway mobility. The Intercounty Connector will relieve congestion along Norbeck Road, and extending Montrose Parkway across Rockville Pike will improve mobility in North Bethesda. Two of the top 10 intersections – Rockville Pike at West Cedar Lane and Connecticut Avenue at Jones Bridge Road are recommended for improvement associated with the Base Realignment and Closure (BRAC)  project at Bethesda Naval Hospital.
