Ever See Those Random Black Lines in the Road? Here's What They Mean

preview

Image // CanvaWe've all seen these things lying across the road, and they seem to be in the most random places. Sometimes they're in the middle of a busy road, other times they're on some&nbsp;rural side street.Have you ever noticed those random two parallel lines running across the road? Have you ever wondered what they're used for?Those parallel lines are actually long, hollow tubes. Called&nbsp;pneumatic road tubes,&nbsp;the "lines" are used for traffic counting and monitoring. They collect data when a vehicle&nbsp;drives&nbsp;over them.Pneumatic road tubes work by sending a burst of air pressure to a counter or a recorder when a vehicle passes over them.Get our free mobile appPneumatic road tubes are obviously too small to slow a car down, so why are they there?Those little tubes are put in place to measure road usage. They're used to figure out which main roads and arteries are the most used, and which roads could be headed to potential problems.Urban planners and municipalities use the data to make decisions about city planning. Using the data, they can decide if a road needs to be widened, repaired or if other routes need to be created to alleviate congestion.The counter is used for a variety of traffic&nbsp;counting&nbsp;purposes. They can&nbsp;register the number, speed, and on occasion, the type of vehicles using that particular road.Yeah, you read that right. These tubes can register your vehicle's speed. Using the two tubes spread at a specific distance and a little bit of figuring, engineers can&nbsp;determine how fast a vehicle is traveling over them and determine if a car is speeding down the roadway.According to this website, engineers say the math is pretty simple. They "just take the distance between the tubes, divide by the time between hitting the tubes,&nbsp;the factor-label method&nbsp;it up, and there you go."Pneumatic road tubes are a practical solution for city planners and engineers. They're highly portable, relatively inexpensive, and easy to install on almost any roadway.They do have a few limitations. The tubes can be affected by weather conditions, things like temperature and precipitation. They can also become victims of vandalism. As vehicles drive over them, the tubes may become misaligned, which could alter their effectiveness.If you've ever wondered what these tubes are used for, now you know.&nbsp; Pneumatic road tubes are one of the most common tools for collecting traffic data.Sooner or later, you're going to run across these double lines - maybe consider slowing down a little bit.Hitting an animal while driving is a frightening experience, and this list ranks all 50 states in order of the likelihood of such incidents happening, in addition to providing tips on how to avoid them.To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.Here are the top 25 states with the lowest cost of living in 2022, using data Stacker culled from the Council for Community and Economic Research.
