Proposed 40km/h speed limit in residential streets of Marden, Royston Park, Joslin, St Peters, College Park and Hackney
Consultation closed 5pm, Monday 28 August 2023.
Traffic speed has a substantial impact on the livability and amenity of our streets and neighbourhoods, and slower speeds are appropriate in local residential streets.
The City of Norwood Payneham & St Peters is working towards improving road safety, encouraging sustainable transport and improving Community Well-being.
We are seeking your views on reducing the speed limit from 50km/h to 40km/h in the residential streets of:
- Marden (excluding Lower Portrush Road)
- Royston Park
- St Peters (excluding Stephen Terrace)
- College Park

Speed limits are in place throughout South Australia and enforced for the safety of all road users.
Speed limits can vary from area to area and can relate to land use, such as the proximity to schools, the level of pedestrian and cyclist activity or if it is a local residential street.
Lower speed limits improve neighbourhood liveability and safety for all road users, without significantly affecting motorist travel times or conditions.

Frequently asked questions
Why is the Council investigating a 40 km/h speed limit in Marden, Royston Park, Joslin, St Peters, College Park and Hackney?
Concerns about high speeds on our roads is a regular issue raised with the Council from the community who want safer streets and nicer neighbourhoods.
A request for slower speeds has been raised by numerous residents throughout this entire precinct.
In 2022, community consultation was undertaken as part of a traffic study in Marden and Royston Park (between Lower Portrush Road and Lambert Road). The majority of survey respondents (60%), supported a speed limit of 40km/h in this area. The Council is considering expanding the proposed speed limit reduction to the surrounding suburbs so that the 40km/h area is bound by arterial roads.
A precinct-based 40 km/h speed limit is a strategy being considered to reduce speed on local roads, increase safety for all road users and improve neighbourhood liveability.
There have been 49 collisions in the last 5-years, on residential streets in this precinct (not including Stephen Terrace).
While collisions may occur at any time and at any location, the lower speed limit has proven to reduce the likelihood of crashes and their severity by providing drivers more reaction time to avoid a collision and increasing the safety of all street users.
What are the benefits of a 40 km/h speed limit?
Lowering the speed limits can benefit the community by calming traffic and encouraging drivers travelling longer distances to use main roads instead of local streets.
A 40km/h speed limit also has the potential to:
- improve road safety for all street users, especially people walking, riding, and using public transport
- prevent or reduce the likelihood and severity of crashes, fatalities and injury
- reduce noise on local streets
- slow vehicle traffic, providing more time and safer options for people to cross the street
- maintain the existing street environment (reduced requirement for traffic calming devices that remove on-street car parks and restrict accessibility)
- provide more opportunities for children to ride to school, as well as create a safer environment to play outdoors.
Does a 40 km/h limit make the streets safer?
Research has revealed that a street with a lower speed limit will experience fewer crashes as it provides motorists with more time to react and prevent an accident.
At lower speeds, the severity of the accidents also decreases. A 40 km/h area provides pedestrians with more time to cross the streets, increasing their safety.
If this change is implemented, will it be a permanent change?
Yes. Should this proposal be supported by the community, endorsed by the Council and the Department of Infrastructure and Transport, the change in speed zone will be permanent.
Will it take me longer to drive to my destination?
Delays experienced by drivers due to a speed limit change would be minimal, and would depend on the distance covered, but in local streets, travel time is more likely to be increased by stopping or slowing at intersections, short street lengths, and on-street parking.
Would a 40 km/h speed limit affect how long emergency services take to reach my property?
No. Emergency services (ambulance, fire, and police) can exceed the speed limit in the case of an emergency. As part of this consultation, the Council wiil engage with South Australia’s Emergency Services and inform them of the outcome.
Why is a 40 km/h area being investigated instead of other traffic slowing devices such as speed humps and roundabouts?
A strategic approach to speed management is required to develop network-wide or citywide safe streets solutions. There are a number of infrastructure and non-infrastructure methods to manage speed reduction.
The introduction of a 40 km/h area is a more equitable and cost-effective solution that can be implemented across a large area at one time, and can avoid the need for restrictive traffic management devices. The streets will be monitored after the ‘settling-in’ period and traffic management devices will be considered if required.
Will existing or planned traffic calming devices be removed or put on-hold?
No – there are no plans to remove existing traffic calming devices, or halt the current plans for traffic calming devices in Marden and Royston Park.
Who will enforce the 40km/h speed limit?
The enforcement of a lower speed limit is performed by the South Australia Police (SAPOL), who work independently of the Council. Changes in speed limits will only be enforced after a reasonable transition period.
The Council does not enforce speed limits nor does it earn any revenue from any SAPOL enforcement activities.
What will happen with the feedback I provide?
All feedback received from the community will be collected, analysed and reported to the Council, which will consider this feedback when making its decision.
The Council meeting date will be added to this project page when it is confirmed.
