The second example of a "new" type of facility for the MUTCD to consider is G Street NE from Washington, DC (provided by Bill Schultheiss of Toole Design Group). The challenge with this type of facility is that it presents a different interpretation of the use of double yellow lines than what's commonly used. The double yellow lines are intended to separate the directions of traffic and insure that the previously one way traffic is not in the path of the cyclist. The challenge with this sort of situation is the on-street parking on the right hand side of the picture. This raises concerns where high speeds on the facility exist. This sort of a facility is a low speed condition where the needs are quite different than in a rural condition. This is continued dialogue that needs broader consideration.
The good news is that the FHWA is leading the charge to encourage flexibility in the design of pedestrian and bicycle facilities, citing both the NACTO Urban Bikeway Design Guide, the ITE Designing Walkable Urban Thoroughfares: A Context Sensitive Approach as examples of documents that provide useful treatments that can be applied to further walking and cycling in our communities.
