Streetsblog pointed me at a study out of Seattle showing very strong transit growth in the central core. Since 2010, the number of jobs in central Seattle has grown by 60,000, but the number of people driving alone to work fell by 4,500. Transit mode share grew by 6 percentage points and is now at 48.4%.
One thing you’ll notice is the preponderance of bus utilization. Historically Seattle has had a bus oriented transit system. The fact that it’s grown not just central city but regional mode share for transit with bus makes Seattle a real candidate city for rail investments. I haven’t analyzed the current proposals in any details, but Seattle has proven itself with transit.
