Speeding drivers see the sign

Published: 05 Oct 2018


A speed initiative that has proven successful on two Cairns streets will be expanded to encourage more drivers to slow down.

Following successful trials at Trinity Beach and Manunda, interactive signs that display the speed of approaching vehicles and messages reminding speeding drivers to slow down will be installed in two more locations next week.

Data collected from the existing signs show a distinct reduction in average speeds.

At Madang Street, the 85 percentile* speed has fallen from 59.8km/h prior to the sign’s installation to 47km/h. At Mayers Street, the 85 percentile speed reduced from 58.7km/h to 46km/h.

The new signs will be installed in Collins Avenue, Edge Hill, and English Street, Manunda.

“The signs draw each driver’s attention to their own speed and remind them to slow down if they are travelling above the speed limit,” Mayor Bob Manning said.

“They also collect data on vehicle speeds so we can track changes in behaviour.”

While the signs can’t be used for enforcement purposes, they do provide data that can be used to inform police patrols.

“For example, we’ll be able to keep track of what times speeding is occurring and Police may use this information to schedule enforcement activities.

“But the real objective is to get people slow down and reduce the risk of injury to pedestrians, other road users and themselves, and improve general amenity in these areas.”

Vehicles travelling under the speed limit will prompt a display of the vehicle speed and a “smiley” face. A few kilometres over the speed limit and the smile becomes a frown.

Between 5km/h and 10km/h, the sign displays the speed and the message “slow down”.

If a vehicle is travelling at more than 10km/h above the speed limit, the sign stops posting the actual vehicle speed and instead displays the signposted speed limit.

“The last thing we want is for drivers to see it as a challenge to try and post the highest speed, so it stops displaying at 10km/h over the limit,” Cr Manning said.

The new signs are expected to be installed early next week. Data is being collected in the lead-up to the installation to allow a comparison of speeds once the signs are activated.

*The 85 percentile represents the speed at which 85 per cent of vehicles are travelling at or below. This is the standard that is used in Australia for determining road design for traffic safety.
