Abstract: Traffic-signal histories record first pedestrian calls but omit subsequent arrivals. We apply a calibrated first-actuation estimator to Sydney histories for 18 September 2018. Screening retains 5,114 movement-hours at 174 sites, yielding an estimated 331,729 crossings. Estimated delay is 3,671.5 pedestrian-hours assuming full compliance and 2,746.3 hours under a transferred behaviour scenario: 39.8 and 29.8 seconds per crossing. Median site flow is 66.5 crossings per usable hour.
