What They Really Do
As it so happens, pneumatic road tubes are mostly used for understanding traffic patterns on a given roadway, and they can be indispensable for planning and design. It’s especially useful for understanding average speeds on the street, how many cars pass over during specific hours, and even what type of vehicle is using the road. This can help officials determine traffic patterns, what road signs to use, what speed limit to enforce, and even if they need to build a new road.
And—you guessed it—if the tube detects a high number of speeders or risky drivers, it could alert police to spend more time in the area!
