EXCLUSIVE BUS LANES FOR CLEANER AIR

Many benefits have been identified in planning for the exclusive bus lanes (EBL) and other transportation proposals for Seattles central business district. The contraflow dual EBL will improve bus service, reduce pollution and save energy by swifter traffic flow in the high volume areas. Bus stops could be relocated so that buses could load simultaneously with the red signal. It is estimated that with the new contras flow EBL system, the average transit speeds of all buses in the CBD will increase from 4.48 to 10.40 mph in peak hours. Travel times will also improve. The average speed of with-flow buses would be improved by over 2 minutes. Dual contra flow lanes can have a capacity of 180 buses per hour. Acceptable levels of service, savings in time, added revenue due to increase in modal split for transit and reduction in personal travel cost are other benefits of the new EBL system.
