In 2023 GHD were engaged by DTP to evaluate  Safe Travel in Local Streets (STiLS) installations in Corio-Norlane and South Geelong to confirm if the program had indeed delivered “safe travel”. Connected Vehicle Data (CVD) was used to evaluate the program comparing driver behavior before and after traffic calming devices were installed. The approach was able to measure safety improvements from installations and residual risk, providing a powerful new way to prioritise limited road safety funding.
