A Field Validation of a Suburban Bus Stop's Live-Arrival Display Against the Bus's Own GPS Trace
A research poster from the School of Continuous Improvement matches a suburban bus stop's live-arrival countdown against the bus's own GPS trace across a 15-week deployment, finding the display agrees closely with the bus while its GPS feed is live (r = 0.95) and barely at all once the feed lapses (r = -0.06, n = 48), with no change to the sign's format across either state.
