If you know San Francisco at all, take a look at Steve Boland’s new map of its high-frequency “main lines.” It’s quite deservedly copyrighted, so I’ve shown just a taste of it here.
For years I’ve advocated that transit agencies need to produce clear maps of their high-frequency networks, so that people can quickly see where they can go without waiting long. I also argue that these maps should be on the wall of every planner, everyone making decisions about social services, indeed everyone who decides where to locate anything. Because ultimately, the most effective public transit is what happens when the city grows in response to the transit network — just as all cities did until about 1945.
