Answer: It is rubber cement. Even though the superior Elmer’s glue had been alive and well since the 50’s, this bottle that looked like a magical elixir crafted by an alchemist centuries ago, was in every one of my classrooms in the 80’s. And for some reason back then they thought making glue look like delicious pancake syrup was a good idea. Luckily just one whiff of this stuff and you’ll know right away that this will not have the sweet taste of Mrs.Butterworth.
The purpose behind those mysterious black cables on the road
If you ever see black cables stretching across the road, you had better know what it means. I had no clue… Check comments.
While on the road, chances are you have spotted the black cables on the road.
However, although they are common and perfectly safe to run over, most people don’t have a clue about their purpose.
These rubber cables, that are stretched across the road, serve the purpose of gathering data about the traffic. So how do they work? When a vehicle crosses over them, it causes pressure which is recorded and transmitted to a counting device.
This information assists transportation agencies in keeping track of traffic flow, vehicle speeds, and volume, which is essential for urban planning, road maintenance, and safety upgrades, ultimately affecting the decisions on traffic management, road expansions, and the positioning of traffic signals or speed limits.
Rubber cables are often positioned in low-visibility areas to avoid drawing attention and to minimize any interference with traffic. This approach guarantees that the collected data is as precise as possible, representing typical traffic conditions without the effects of altered driving behavior.
