5.5 mph baseline, weighted so busier routes count more (the pre-plan year)
4.54 mph on the corridor's own segments (segment-clipped baseline)
+0.2% July 2026 vs July 2025 (5.56 to 5.57 mph). Pre-plan months on these routes swung −4.4% to 0.0%. Too soon to call.

RouteBaseline mph Riders/dayFull-run time (derived) Trend
M55 5.35 1,395 50.8 min full run
M5 6.3 4,714 83.0 min full run
M7 4.99 7,006 94.2 min full run

Full-run time is derived: route length divided by average speed. Rider counts are fare-paid boardings, weekdays 7am–7pm, on tracked local routes. The plan's own rider figures count all riders, all day, so they run higher.
