Main Roads Western Australia wanted to compare driver behaviour before and after the installation of 4 new compact roundabouts in Osborne Park as part of the Urban Road Safety Program. The purpose of the Urban Road Safety Program is to introduce low-cost road safety treatments that modify driver behaviour. Specifically, they wanted to look at differences in car movements, speeds, and braking behaviours before and after the installation.
In this case, the treatments are intended to reduce driver speeds through the treated intersections, and potentially reduce speeds between the treatments. The purpose of these treatments was to reduce near-miss events - friction less events that are leading indicators of road safety risk. GHD was the consulting partner for this project, comparing and analysing data before and after the installation.
Using average speeds, vehicle turning movements, and average braking (g-forces) on the approach to intersections at these locations, MRWA was able to confirm the effectiveness of the treatments.
There was a small decrease in braking between the before and after periods on the entries to the intersection that were subject to a stop or giveway control (blue boxes). Itβs likely that drivers were not coming to a complete halt before navigating the roundabouts.
