LED Road Signs program
The aim of the program is to reduce the number of accidents and near-misses at these known hotspots. The road signs are designed to:
- alert drivers of an upcoming intersection or traffic hazard
- have drivers reduce their speed if they are travelling above the speed threshold that is pre-determined for that location.
About the signs
The LED road signs have two main components:
- Lower section - a rectangular-shaped sign with 'slow down' spelt out in highly visible LEDs.
- Upper section - a diamond-shaped sign featuring a symbol or icon representing the upcoming hazard at that location. Common diamond signs include symbols or icons for pedestrian crossing ahead, curve ahead, roundabout ahead and winding road ahead.
The LED road signs are permanently installed via a post and small concrete foundation on the Council-owned road verge. The signs are solar powered and have a small solar panel to keep the batteries charged.
How the signs work
The signs are vehicle activated and trigger by an approaching vehicle. The LEDs on the signs are inactive (unlit) by default. As a vehicle approaches, the sign's radar detects the speed.
The sign will only activate (light up) if a vehicle is travelling above the pre-determined speed threshold for that location. If the vehicle is travelling under the pre-determined speed threshold, the sign remains inactive.
The speed threshold at which the sign activates is not the speed limit for the location. It is the pre-determined safe speed to approach the upcoming intersection or traffic hazard.
Site selection for LED road signs
Local councillors work closely with Council officers to identify and prioritise suitable locations for the LED road signs. Council bases the locations shortlist on data from:
- Council's investigation history including known traffic hotspots and accident data
- feedback from each local councillor
- Queensland Government's Webcrash database.
