How street connectivity affects transit
1. Anything that affects walkability affects transit
2. The number of people within walking distance of each transit stop affects ridership…

Created by TransLink in Vancouver, BC.
3. Transit is most useful to the greatest number of people when it can travel long, straight paths.
Transit is useful to fewer people when it has to thread itself through a labyrinth or go in circles.
4. Transfers at intersections are part of a strong transit network.
• During development review of large parcels• In neighborhood opposition to new street
connections, a.k.a. “cut through traffic”• By building new paths and bike boulevards• In local land use plans (e.g. North Bethany in
Washington County)
