Have you ever noticed the black cables stretched across the road as you’re driving on highways or through your neighborhood?

You may have wondered what they’re for, but rest assured, there’s no need for concern—they’re harmless to drive over.

Let’s dive into understanding what these mysterious cables are and why they’re important.

These black cables are actually known as road tubes, and they play a crucial role in helping local transportation agencies gather valuable data on traffic patterns.

By positioning them discreetly, they ensure minimal disruption while effectively collecting necessary information.

So, what exactly happens when a tire rolls over one of these cables?

Each time a vehicle crosses the tubing, a burst of air is sent through it to an attached counter, capturing essential data.

Once this equipment has been in place for a designated period, it’s time for the data to be collected and analyzed.

The primary function of these tubes is to count the number of vehicles that pass over them. However, they offer even more insights.

By measuring the time between each air pulse, they can identify peak traffic times, providing a clearer picture of busy periods.

When road tubes are installed in pairs, they can reveal additional details such as the types of vehicles traveling, their speeds, and their directions.

This information becomes invaluable for planning and making informed decisions.

For instance, if data indicates unusually high speeds, transportation officials might consider reviewing and possibly updating speed limits or adding more signage to improve safety.
