[sustran] Re: Bus Segregation, Car equivalents of BUS

[Todd Alexander Litman]

There are tables indicating the Passenger Car Equivalents (PCE) of 
heavy vehicles, including buses, under various roadway conditions 
(see http://www.vtpi.org/tca/tca0505.pdf, Table 5.5-4).

You may want to review the "High Occupancy Vehicle Priority" 
(http://www.vtpi.org/tdm/tdm19.htm ) and "Bus Rapid Transit" 
(http://www.vtpi.org/tdm/tdm120.htm ) chapters of our Online TDM 
Encyclopedia, which discuss dedicated bus lanes and how to evaluate 
their benefits. These chapters reference several relevant technical 
reports and websites on the subject.

In developing cities, busways and other types of transit service 
improvements are among the best ways of improving transportation 
system performance, both to the people who ride transit and to 
motorists who experience less traffic and parking congestion if their 
neighbors shift from driving to public transit.


Best wishes,
-Todd Litman
