It took me quite a few minutes of staring at the map at right (and the schedule) to figure out the path that Route 102 actually takes.
Two things are frustrating about this kind of graphic design. First, lumping a bunch of routes into one map makes a lot of sense from a printing-paper-schedules perspective, but not when done online.
Secondly, it’s been about two years since Community Transit — not exactly rolling in cash themselves — managed to produce exceptionally clear and attractive route maps. In the original thread on this topic, commenter sachtu adds insult to injury by pointing out that CT contracted with King County‘s GIS deparment to produce those maps. So it would be a matter of Metro metaphorically literally walking across the street downstairs.
