Dear Mr. Smith,
We, the undersigned, request the Maryland State Highway Administration (MDSHA) implement pedestrian and bicyclist crossing improvements at highways MD-212/Riggs Road and MD-410/East West Highway which intersect M-NCPPC Sligo Creek Trail and highway corridors near the park trail.
These popular Sligo Creek Trail crosswalks at state highway intersections present a significant threat to vulnerable pedestrians and bicyclists as a consequence of inadequate signal facilities, excessive driver speed for conditions, substantial crossing distances, several multi-threat travel lanes, exposure from high vehicle volume, lack of shoulders and center median (MD-410), and obstructed crosswalk visibility. In short, these crosswalk systems are compromised.
We request the following suite of Safe System elements be implemented by MDSHA to provide adequate crosswalk safety:
- Narrow Travel Lanes
- Remove Visibility Obstructions and Barriers
- Build a Pedestrian Island Refuge (MD-410)
- Extend Bike Lanes (MD-212)
- Implement a Road Diet (MD-212)
- Implement Context-Driven Safe Speed
- Upgrade the Crosswalk Beacons
These Safe System elements work together as an ensemble to keep vulnerable crosswalk users and drivers safe. These recommended Safe System elements are summarized in Table 1.
This is a major safety issue.
- Vulnerable pedestrians and bicyclists on key trail crossings, which include school children, are currently exposed to high speed, high volume (23,000 vehicles per weekday) traffic, crossing several dangerous multi-threat lanes with inadequate or non-existent shoulders. The crossing systems are also compromised by obstructed sightlines from the presence of blind (sag) curves, utility poles, and bridge wall visibility blockages.
- These compromised trail crossing systems have resulted in numerous documented Maryland State Police crashes resulting in the crossings being identified as medium to high pedestrian and bicyclists crash “crash hot spots” in the MDOT Maryland Bicycle and Pedestrian Master Plan (2019).
The design ignores equity and land use contexts.
- These highway corridors serve a highly disadvantaged and chronically underserved majority-minority community and included within Maryland Equity Emphasis Area, Priority Funding Area, and Health Outcomes SocioNeeds Area.
- These trail crossings serve a dense urban community (10,000 residents per square mile) with extremely high percent of no-car households (30%) satisfying demand created by numerous nearby (<0.25 mile) amenities including elementary schools, park and recreation centers, and shopping centers.
Sligo Creek Trail is a major part of our transportation system.
- These trail crossings are an integral component of the Anacostia Tributary Trail System (ATTS) serving seven regional and national trail systems thereby helping Maryland promote its rich and diverse cultural, historic, and environmental, and heritage.
- These trail crossings provide 23,000 residents critical links six transit stations from four rail lines (WMATA Purple, Red, Green, Yellow Lines and MVA/MARC Camden Line) meeting growing demand for accessibility within the region’s multi-modal transportation system which include significant Transit/Trail Oriented Development, upgraded nearby bicycle facilities (MD-500, MD-193, Ager Rd), and the 670 bicycle fleet Prince George’s County Bike Share Program.
Our request is consistent with MDOT/MDSHA’s “context driven” engineering guidelines. These MDSHA guidelines include safe speed limits, continental crosswalks, and specialized signals. Similar Safe System elements are being implemented by MDSHA through the MD-500/Queens Chapel Project. Prioritizing Sligo Creek trail crossings is also congruent with MDOT policy goals promulgated by the Maryland Bicycle and Pedestrian Master Plan (2019).
Finally, our Sligo Creek Trail crossing Safe System recommendations are consistent with Federal Highway Administration (FHWA) Safe Transportation for Every Pedestrian (STEP) recommendations, MDOT/MDSHA urban mobility-focused streetscape policy, and MDSHA cost-effective pedestrian safety countermeasures currently being undertaken.
Thank you for your urgent attention to making the M-NCPPC Sligo Creek Trail crossings safe.
Sincerely,
