<html> <body> There are tables indicating the Passenger Car Equivalents (PCE) of heavy vehicles, including buses, under various roadway conditions (see <a href="http://www.vtpi.org/tca/tca0505.pdf" eudora="autourl"> http://www.vtpi.org/tca/tca0505.pdf</a>, Table 5.5-4). You may want to review the "High Occupancy Vehicle Priority" (<a href="http://www.vtpi.org/tdm/tdm19.htm" eudora="autourl"> http://www.vtpi.org/tdm/tdm19.htm </a>) and "Bus Rapid Transit" (<a href="http://www.vtpi.org/tdm/tdm120.htm" eudora="autourl"> http://www.vtpi.org/tdm/tdm120.htm </a>) 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.

It is said that a BUS is equivalent to 3 passenger cars. But I also find there is lot of debate on this value. Can anyone suggest what values should be taken?   I have also read some reports about Bagota, and also some discussions in this group, which suggest that segregation of buses helps improve regular traffic as well as buses as they get dedicated lanes.   How can I quantify that this segregation indeed improves the regular traffic ?   Are  there any published reports which can justify this.   My main constraint is space. I will have to extract a lane from the existing carraigeway as it is bound by private property.</blockquote> <x-sigsep></x-sigsep> Sincerely, Todd Alexander Litman Victoria Transport Policy Institute (<a href="http://www.vtpi.org" eudora="autourl">www.vtpi.org</a>) litman@vtpi.org Phone & Fax 250-360-1560 1250 Rudlin Street, Victoria, BC, V8V 3R7, CANADA “Efficiency - Equity - Clarity”   </body> </html>
