Sorry, I meant ridership per capita. In Seattle about 15% of people commute via transit (and I believe it’s the fastest increasing in the country), but LA is 6% and flat.
Seattle’s geography is conducive to transit, because there are many bridges where all traffic is constricted. That means point to point trips by car are often taking a similar route to buses. It also restricted the city’s ability to sprawl (although even suburban Bellevue is above LA at 8%).
The standard of service for nearly every bus line that operates in Seattle is 15 minutes frequency, even on weekends. Many lines operate every 10, and the new G Line that opened last year in fully dedicated bus lanes runs every 6!
