New bikeway design guide

bike lane buffered from parking

The National Association of City Transportation Officials (NACTO) has published an online guide to modern bicycle facilities, the Urban Bikeway Design Guide. This easy to use guide provides examples and specifications for a large number of progressive facilities of the sort that have long been used internationally and are becoming common in several large and medium sized north American cities.

Though Carson City has only some urban characteristics, there are nevertheless several great ideas here that could be used in Carson City to provide a safer and more welcoming climate for bicycling. For example, buffered bike lanes (buffered from motor vehicle traffic and/or parked cars) could make many people more comfortable riding on the street, as well as use up some of the excess pavement that exists on four lane streets with low traffic volumes (Saliman between Colorado and Sonoma, for example). Shared lane markings could replace “share the road” locations such as Hot Springs Rd, with the addition of “bikes may use full lane” signs rather than the “share the road” signs currently placed. Take a look at the guide, and I’m sure you’ll see a number of ideas that could be implemented here in Carson City.

The guide has photos, diagrams, measurements, clear language about what is MUTCD and AASHTO bike guide compliant, and links to projects where the treatments have already been successfully implemented.

Streetsblog has a post that introduces the guide.

  1. Good question. There are other diagrams that show buffering from motor vehicles, and there are good arguments for both, and when there is sufficient space, there probably should be both. Statistically, getting doored by drivers exiting parked cars is a slightly higher risk that the “hit from behind” crash that worries so many people but is actually very uncommon. Both crashes are actually quite uncommon, far less than right hooks (right turning driver cutting off straight through bicyclist) and left crosses (driver turning left into the path of a straight through bicylist).

  2. for my money, if it clear that cyclists — and more importantly, would-be cyclists — prefer buffers to protect from cars, then do that, because then we get more cyclists, which brings on the safety-in-numbers, etc.
