Every so often, every city should do a "system reimagining" of its bus network like Houston METRO did.

Back in 2012, Houston's bus network was in trouble. Ridership was down, and weekend ridership was especially weak. Frequent service was rare. Routes didn't go directly where people needed to go. If you wanted to get from one place outside downtown to another place outside downtown, you still had to take a bus downtown and transfer.

It was a system that had basically stayed frozen since the 1970s. And as you can surmise, the service it provided was not effective, convenient, or appealing for many types of trips.

METRO's solution was to wipe the slate clean. What would Houston's bus network look like if you designed it from scratch? By re-examining every bus route in the city, talking to bus riders, and making tough decisions, METRO reinvented its bus network. The new system features better, more efficient routes, shorter wait times, and increased service on nights and weekends. The changes were essentially revenue-neutral -- Houston now runs a better bus system on the same budget, because it optimized the use of existing resources.
