Counting traffic for better roads

Two traffic counters have been deployed around Port Lincoln and will be moved weekly to help the Port Lincoln City council decide how to seal the road in upcoming scheduled reseals.

The traffic counters, which consist of a box that holds the recorded data and two pneumatic road tubes which stretch the length of the road, counts the classes of vehicles including motorcycles, cars and trucks, and the number of axles on trucks.

Port Lincoln City council manager of operations Craig Matena said the counters also record the speed and direction of the vehicle travelling on the road.

He said the counters were used to determine traffic movements on a section of road to assist in the seal design in specification for upcoming scheduled reseals. 

“It changes the application rate that you lay bitumen (or asphalt) at,” Mr Matena said.

Mr Matena said depending upon the number and types of vehicles the amount of seal could change on the road, and by getting the amount right it would reduce wear and tear on the road and asphalt bleeding onto cars.

Mr Matena said the council owned two counters and they were moved on a weekly basis to provide data for different roads in Port Lincoln.

He said the counters were deployed at this time each year in the lead up to the next financial years reseal listings.

He said the counters were not used to determine which roads in order of priority are to be resealed, but instead were a tool to assist with the reseal design, by taking into account the classes of vehicles travelling on the roads.

Among the upcoming roads to be counted are Windsor Avenue, London Street, Bligh Street, Pine Freezers Road and Washington Street.
