A School of Continuous Improvement poster scores suburban bus-stop bays against five named waiting levels and delists any staff-served stop below Managed from the Commute Assurance Map.
A five-level model of numbered bus-stop bays now gates the commuter-travel allowance
The Commute Assurance Map is about to get shorter. A new poster from the School of Continuous Improvement scores the numbered bay at suburban bus stops against five named levels of kerbside waiting, and writes Managed as the floor that keeps a stop on the map.
Dr Osei Vandermeer, Research Fellow and Convenor of the Review Cadence Observatory, led the work with Postdoctoral Fellow Joost Nwosu and Lecturer Solveig Adeyemi. Forty-seven stops across four operators were scored at four quarterly audits. A rater who had not seen the operator name assigned the level; two observers timed kerb-arrival to last passenger aboard.
Nineteen stops moved from Dispersed to Instrumented in a single cycle after a stencil kit arrived, skipping Lined and Marshalled. Mean boarding interval at those Level-4 stops was 48 seconds, against 46 seconds at remaining Dispersed stops. Operator rank by share of stops at Level 3 or above inverted for the kit-adopting operator between the second and third audits.
The stencil can put a stop at Level 4 before the next bus arrives. Boarding does not move with it.

The University records the finding as evidence that a named level can carry an eligibility condition a boarding scramble never could. From the next review cycle, any staff-served stop below Managed is delisted from the Commute Assurance Map, which is the eligibility condition for the commuter-travel allowance, with no exception sustained beyond a single review cycle.
“A stop that has been stencilled is a stop the map can keep,” said Dr Nwosu. “The allowance then has to live with whether anyone still misses the bus.”
