Safer speeds reduce the likelihood of, and the consequences of, crashes on our local streets.
This image outlines how a person hit by a vehicle has a better chance of survival if the person driving travels at 40km/h or less.
In 2012 we introduced 40km/h streets in the area of Toorak and Prahran bordered by Punt Road, Toorak Road, Williams Road and Dandenong Road. In 2016 we introduced 40km/h zones to the residential precinct bordered by Williams Road, Orrong Road, Alexandra Avenue and Dandenong Road.
We have evaluated the impact of the 40km/h speed limit in these areas and found that overall crashes have almost halved since the new limit was introduced.
Following implementation, total crashes reported by police reduced from 70 to 38 (when comparing the three-year periods before and after they were introduced). The number of people injured in these crashes fell from 137 to 79, and the number of vulnerable road users (people walking, riding a bike or motorbike) who were injured fell from 46 to 22.
While the number of crashes and minor injuries dropped, the number of serious injuries remained stable – highlighting the vulnerability of walkers and riders if they’re stuck by people in vehicles.
At above 30 km/h impact speeds, pedestrians are at considerably greater risk of death.
We are now consulting with residents about expanding 40km/h zones to more neighbourhoods, and trialling 30km/h in areas where there are a high numbers of vulnerable road users mixing with vehicles - such as near schools, on the Stonnington-controlled section of Chapel Street (between Dandenong and Toorak roads) and on local streets identified as safer alternatives to main roads for people who want to ride bikes to get around in Stonnington.
It is anticipated the 30km/h trials will have minimal impact on average journey times in trial areas during peak periods, while reducing the incidence of excessive speeding in parts of Stonnington frequented by vulnerable road users (near schools and shops).
The image of Greville Street illustrates where infrastructure improvements have supported a reduced traffic speed and made walking and bike riding much safer.
