How to read it

What this map is showing

Each route is colored by expected rider time loss, not just slow vehicle movement. The published number combines extra waiting before boarding with extra time spent riding.

Waiting matters most: owl routes can rank high because sparse, uneven overnight headways create large rider wait penalties.
Red does not mean traffic alone: a high-loss route can be driven mostly by waiting, mostly by ride time, or by both.
Use route detail pages for evidence: open a route to see its worst stop wait, worst segment, and sample sizes behind the summary.
