[sustran] Re: land use control and levels of motorization

[Todd Alexander Litman]

I agree with Zvi. The debate between Bus Rapid Transit and rail-based 
transit is partly a debate between "mobility" and "accessibility." 
Rail systems tend to provide a catalyst for more compact, accessible 
neighborhood development which shows up in reduced per capita vehicle 
ownership and mileage, and therefore reductions in per capita 
congestion delay, transportation costs, parking costs, accidents, 
energy consumption and pollution emissions 
(http://www.vtpi.org/railben.pdf ). It also results in higher local 
property values and improved mobility for non-drivers (see the newly 
revised literature review at http://www.vtpi.org/smith.pdf ). BRT 
appears t have some of these impacts, particularly if implemented in 
conjunction with supportive land use policies, but rail impacts are 
greater and more likely to attract higher-income riders, and gain 
voter support.


Best wishes,
-Todd Litman
