I was reading Human Transit today, and thinking about the rail map. SLC has a similarly complex bus system. Why is not possible to have a similar map? Jared Walker has the right of it when he says 'many transit services that are stuck in mixed traffic'. This is the fundamental divide--not bus vs. train, but dedicated right of way vs. mixed traffic. Trains, being heavier and slower to stop, frequently get their own. Buses do not, and that makes all the difference. Effective BRT means dedicated right of way
