Review Seattle Schedule 2 route info. stops are not in sequence. they are in alternating direction order (a non-sequitur zig-zag amalgam, as if made by an AI program that alphabetized stops, rather than looked at route-map
I was waiting for the 550 at bay 9 of the bellevue transit center and one bus away said a bus is arriving, but it never showed up. The 550 came a few minutes after the ghost bus disappeared from the arrivals screen and 5 min before the next bus was predicted to show up.
