Capability 4

Speed, evaluation & connected vehicles

Before/after evaluation that reports what the data can support — no more, no less — plus connected-vehicle methods tested against instrumented cars.

CapabilityWhat it is
Speed-zone change evaluationSix NSW sites, weighted difference-in-differences and rolling coefficient of variation. Case note →
Aggregation biasConnected-vehicle before/after that separates path-level speeds from aggregate averages, which can mislead.
Research-car speed auditConnected-vehicle speed data compared with two instrumented SafeFuture research cars (method published).
Before/after engineComparison-group and Empirical Bayes before/after, where every study returns an estimate with its interval. Barry Road →
Driver telematics studyA 200-driver OBD telematics study with UNSW ethics approval (with conditions); no results yet.
