Comment:
This section describes the observational field studies conducted to evaluate the allocation of roadway width on both bicyclists’ and motorists’ lateral positioning, taking into consideration various roadway characteristics.The roadway characteristics that factored most into the site selection process were: Bicycle volume, Traffic volume, Vehicle mix (i.e., percent trucks), Lane width or total roadway width, Presence/absence of on-street parking, Posted speed limit, and Grade.

Abstract:

TRB’s National Cooperative Highway Research Program (NCHRP) Report 766: Recommended Bicycle Lane Widths for Various Roadway Characteristics presents an analysis of the research and design guidance for bicycle lane widths on existing travel lane widths and parking lane widths. The conclusions are most applicable to urban and suburban roadways with level grade and a posted speed limit of 30 mph and should be used cautiously for the design of roadways with motor vehicle speeds outside of the range of 25 to 35 mph, and in particular for higher-speed roadways.
