The wide blue line is light rail and the red lines are the new Rapid Bus product (both frequent and relatively fast). The rest of the bus network is clearly presented in ways that advertise its frequency and span, so that (a) the Frequent Network jumps out at you and (b) services that run only at rush hour recede from attention so that you can clearly see the network that runs all day. They do this by using black (numbers and lines ) for the Frequent Network, then solid blue for the other all-day service, then paler blue with blue-outlined white number bullets for the peak-only services.
Works for me. What do you think? If your transit agency hasn't figured out Frequent Network mapping yet, show them this map, and tell them to read Chapter 7 of my book, or this!
