A School of Continuous Improvement paper codes the exchanges between drivers at 38 shopping-centre car-park junctions into five kinds, and the University adopts one of them as the only permitted yield in its staff car parks.
A School of Continuous Improvement paper sorts 2,146 aisle-junction meetings into five kinds of yield, and the University stencils the Palm at 22 staff junctions
The line painted across a car-park aisle says who goes first, and a good many drivers have gone second anyway. “How Many Kinds of Yield Does a Painted Give-Way Line Contain, and Which Should a Staff Car Park Permit?”, a paper released today by the School of Continuous Improvement, records 2,146 meetings at 38 junctions in five suburban shopping-centre car parks and sorts the exchange between the two drivers into five named kinds: the Palm, the Nod, the Still, the Flash and the Beckon.
A junction is a small room that two people share for about three seconds, and it turned out to be a courteous place to spend a season. We hope the questions it raises are taken up by the people who park there.

The paper, by Ms Nwafor with Dr Thandiwe Solberg and Dr Solveig Adeyemi, builds its list over three passes of observer coding and reports that the kinds clear a junction at different speeds and keep much the same proportions from one car park to the next. The school’s habit of counting before ruling has here been carried out to the aisle.
The University has taken the Palm as its own. A stencilled hand now marks 22 staff-car-park junctions, and from the next teaching period a permit holder recorded yielding by any other kind three times in a term will give up the permit’s priority bay for the following term. The rule makes no allowance for visitors or hire vehicles. Dr Solberg, Senior Lecturer and Convenor of Demo Quarter, said the stencil “gives each junction a sentence it can finish”.
The University counts it a privilege to tell its drivers, at last, what a yield looks like.
