Project Background

We’ve received feedback from local residents about speeding in Downer and Reynell Streets. In response, we reviewed these concerns using our approved Road Safety Assessment (RSA) procedure and determined that the installation of new traffic controls is required in both streets.

Traffic Monitoring

We monitored traffic speeds continuously over 7 days to identify whether changes were needed.

Downer Street
85% of drivers travel at speeds of up to 50.8km/hr in a 40 km/hr zone, which qualifies for traffic control measures based on RSA guidelines.

Reynell Street
85% of drivers travel at speeds of up to 48.8 km/h in a 40 km/h in a 40km/h zone. This also qualifies for traffic control measures based on RSA guidelines.

What traffic calming is being proposed?

Downer Street and Reynell Street (excluding intersections)
To address high speeds, we are proposing traffic control measures along both streets.

Two options are being considered:

1. Watts Profile Speed Humps – Asphalt humps designed to slow traffic.

2. Speed Cushions – Rubber humps placed in the lane centre, allowing smoother passage for bikes, buses, and emergency vehicles. These will be installed in series and spaced according to current standards.

Example of Watts Profile hump Example of Speed cushions

Aroona Road / Reynell Street Intersection Upgrade
The intersection at Aroona Road will be improved with a raised and narrowed layout to control traffic. This design is subject to a stormwater investigation.

  • Current issue: 85% of drivers on Aroona Road travel at speeds of 49 km/h.
  • Proposed solution: A raised intersection and narrowed road to reduce speed.

Wilpena Terrace / Reynell Street Intersection Upgrade (Stage 2, 2025/26)
Similar improvements are planned for this intersection, including a raised and narrowed layout, subject to stormwater analysis.

  • Current issue: 85% of drivers on Wilpena Terrace travel at speeds of 47 km/h.
  • Proposed solution: A raised intersection and narrowed road to slow traffic.

Example of a raised intersection (Arlington Terrace, Welland)

Reynell Street at Alton Reserve (Stage 2, 2025/26)
The 10-metre-wide section of Reynell Street at Alton Reserve has indented parking alongside the reserve. To address safety concerns, particularly for children, the following options are being considered:
  • Raising the roadway (subject to stormwater analysis).
  • Adding decorative street print and planting more trees for improved aesthetics.
  • Retaining parking while implementing traffic calming measures

Traffic treatment location plan

The concept plans show the Watts Profile humps, however the location of each treatment is the same for Speed Cushions.
