Have you ever thought, what are the rubber tubes stretched across the road?
Those tubes help planners with the Department of Transportation build better roads.
Every two years, the DOT uses the devices on state maintained roads to count traffic.
With the data, engineers like Pat Wilson can project how many cars will use the road in the future.
"We can show that the improvements we are going to make, is going to mitigate future traffic increases and take care of any congestion in the future," Wilson explained.
Engineers aren't the only people interested in the numbers, land owners are interested as well.
"Developers that call in want to know the traffic volumes on a certain road where they are looking to develop property, so they try to maximize their property versus how much traffic on the particular road," he explained.
Updated traffic counts are placed on the Department of Transportation's website.
