  • Limited system based on traffic calming projects in the 70s and 80’s particularly strong in the inner eastside neighborhoods that have some of the highest bicycle mode splits in the country. Limited service area.
  • Current projects expand the network to serve neighborhoods in the north and east, which are two of the most ethnically diverse neighborhoods. I will talk in more detail about threet
  • Goal by 2015 is to have a system that serves the whole city, including more difficult areas to serve in the southwest and east
  • Bicycling is good for our scarce transportation resources. By way of example, for $60 million we can construct 300-miles of North America’s best urban bikeway network or we can construct approximately one mile of urban freeway.
  • This is small but critical element, most of the system already existing, we found that just put in signs made the streets much more usable. Used a stimulus grant to put in 2000 sharrows on current and planned routes, all of the sudden people could make sense of the system just follow the sharrrows.
  • The biggest obstacle to more biycycle use of neighborhood greenways is crossign busy streets, we have used a series of different mechanisms
