[sustran] Re: Effect of bicycle lane marking on bicycle usage

[Todd Alexander Litman]

A number of studies indicate that communities which improve cycling 
conditions, including bikelane development, experience significant 
increases in bicycle travel and related reductions in vehicle travel. 
Each mile of bikeway per 100,000 residents increases bicycle 
commuting 0.075 percent, all else being equal (Nelson and Allen, 
1997). Dill and Carr (2003) find that for U.S. cities with more than 
250,000 population, each additional mile of bike lanes per square 
mile is associated with a roughly one percentage point increase in 
bicycle commute mode share. Rietveld and Daniel (2004) find that 
bicycle transportation increases in cities where cycling is 
relatively easier (fewer hindrances along cycling routes) and safer, 
and as cycling is faster and cheaper relative to automobile travel.
