Transit agencies had to plan specifically for essential workers, typically off-peak commuters, low-income, female, black, indigenous, or people of color. If ridership equalizes throughout the day, maybe it no longer makes sense to double train or bus service during morning and evening commute peaks — and we should instead run steady, dependable headways for a longer day span.
