The Maryland Avenue Safety Project has entailed numerous technical studies yielding the following data and reports about traffic, use and safety along the maryland avenue, NE, corridor in Washington, dC.


Project and data overview

> Presentation by DC Department of Transportation (DDOT) in May 2015 explaining the project vision and related data, including traffic volume, speeds and crashes; interim changes; and project timeline


Background studies

Studies related to transportation needs/safety on Capitol Hill from cars, to bikes, to pedestrians:

> December 2006 - Capitol Hill Transportation Study

> April 2009 - DC Pedestrian Master Plan

> 2009 - Safe Routes to School federal legislation

> January 2012 - DC Streetcar Land Use Study, Phase One, which includes the data on impacts and mitigation on the H Street/Benning corridor and the area within .5 mile radius of the corridor

> September 2013 - Speed Limit and Safety Nexus Study that shows traffic volumes at 7th and D Streets along Maryland Avenue, NE

> October 2014 - We Move Strategic Multimodal Long-Range Transportation Plan from DDOT

> December 2015 -  Vision Zero Safe Streets Action Plan from Mayor Bowser and DDOT

"Road diet"

Examples of how the ‘road diet’ -- similar to what is proposed on Maryland Avenue -- has worked in communities around the country: 

The Federal Highway Administration claims that road diets have "stood up over the test of time” -- nearly 30 years -- to show improved safety with no impact on traffic capacity when implemented in volumes below 20,000 cars a day

> A video (from city planner, urban designer, and author Jeff Speck) with four examples of road diets. Speck cites studies of road diets in 17 North American cities that show zero net decrease in automobile traffic capacity because of the road diet.

> "So What Exactly is a Road Diet?" from City Lab tracks what various cities are doing related to road diets, and the results


DDOT study documents

Documents used by DC Department of Transportation (DDOT) in evaluating options related to the Maryland Avenue Safety Project, with analysis and discussion of long-term traffic volume estimates; speed and safety within the corridor; potential neighborhood impacts like traffic diversion; and historic and aesthetic requirements:

> Comprehensive analysis of environmental impact of the Maryland Avenue Safety Project, submitted to the Federal Highway Administration in December 2015

> Technical traffic engineering analysis of the Maryland Avenue corridor and surrounding streets, performed by a third party transportation engineering firm, issued 2012

> Technical analysis of future (2040) traffic volume for the Maryland Avenue coordinator and surrounding streets, issued 2012
