−0.9% July 2026 vs July 2025 (5.02 to 4.98 mph). Pre-plan months on these routes swung −9.0% to −0.8%. Too soon to call.

RouteBaseline mph Riders/dayFull-run time (derived) Trend
M34+ 4.99 4,799 32.9 min full run
M34A+ 4.91 4,564 33.1 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.
