Like all road authorities across Australia, we use many different techniques to understand how people use the State Road network. We’ve put together the answers to some of our frequently asked questions below.
We regularly study traffic patterns across the State road network.
We use the data to find out the volume of traffic traveling through an area, the time it takes to get from one place to another, vehicle turning movements and the number of vehicles passing through sites.
This information helps us find ways to improve road conditions and travel time reliability and make our roads safer.
No personally identifiable information is collected or kept by us in the course of these routine surveys.
We collect data in many ways, including hand counts, vehicle counter tubes on the road surface, and sensors that measure how long it takes to travel between two points.
Every Monday we release the Roadworks Roundup, a list of all planned roadworks that may impact traffic on State roads. If a survey or works to install survey equipment might impact traffic, they are included in the Roundup.
You may have seen our sensors around, or our technicians installing them.
Traffic tubes are usually black and lie across the road. Other sensors are often contained in small boxes attached to traffic lights, or on poles near the side of the road.
If we’re doing a hand count, you may notice a technician with a small clicker at the side of the road.
As part of a heavy vehicle origin-destination traffic survey, traffic cameras are being installed in Launceston during February 2020.
The cameras will record heavy vehicle movements around Launceston to inform transport planning work that we are currently undertaking in the Launceston area. This work includes investigations into a second Tamar River crossing.
The cameras will be installed for one week period from 22 February 2020.
The Department will not have access to any personally identifiable information as a result of these surveys.
While we’ve already done a broader level origin-destination study, with the results summarised in the Launceston Traffic Origin-Destination Report May 2018, this survey will provide a more focused break-down on heavy vehicle movements.
