At grade pedestrian crossings are assumed to have no quantifiable safety benefits in Queensland. Raised pedestrian crossings, on the other hand offer significant benefits. They lower vehicle speeds at the crossing point, reducing the likelihood and consequences of crashes. A Crash Reduction Factor of 63% is assumed in the model parameters for the Austroads Pedestrian Crossing Tool.
In 2023, speed cushions were retrofitted to an existing pedestrian/zebra crossing on a collector street on the Sunshine Coast, with a posted speed limit of 60km. Data shows 85th percentile speeds decreasing at the site from 55km/h before installation, to 40km/h following installation. This suggests the installation provides significant safety benefits for users.
This presentation describes how the need for this unconventional treatment was identified in a school planning study that used spatial engagement tools. It also describes how foreseeable benefits of the project were predicted using a case study project involving a refuge crossing, on a road with similar characteristics.
The project site forms part of a route to school and positive experiences have been reported by users. It may inform methods for planning low cost infrastructure improvements around schools.
