What is this thing?

You can often get out of a speeding ticket thanks to this, as it's pretty common for the traffic studies to be out of date or to have flaws that you can argue about.

The typos started at the precise moment your mind was blown.

Please don't change them.

Kinda true. Regular cars have an Equivalent Single-Axle Load (ESAL) of 0.0004. Basically, it takes about 9,600 cars to put as much wear on the pavement as one 5-axle Semi.

Thank you for taking the time to reply. This is great information!

Would you share a story or two of your time doing this?

Pretty sure it'll be seen as noise and ignored. The algorithms aren't perfect but they're pretty tight and look for specific things. Unless you can emulate with a reasonable level of accuracy what is looking for it'll just ignore what you do.

There's a timing tolerance you can program. So if you only want to count double axles or get the speed data based on a presumed axle spacing, you can program that in. But, if you feel you must spoof it, listen to the sets of tires as they cross the hose and match that timing while stomping on the hose. You need to stomp pretty hard to get the hose to compress enough and you need to generate an air hammer pressure wave within the hose. This and the intensity is what is measured by the device and recorded as an event.

But these modules are left for weeks to months. So if the counts are all in the, let's say, 300 range daily but then one single day shows 1000, that day's data is typically removed from the set. Outliers can happen for all kinds of reasons (e.g. failure, hose break, weather, loss of solar power, unusual or atypical activities, children young and old). So, if the counts are wildly different than prior years' counts, daily/weekly/monthly inconsistent, beyond comprehension, or obviously defective; they can set up more than one device if they need and some devices can receive more than one input. They can also program the device with multiple inputs to only record data within a specific range of parameters. So there are lots of ways to limit the shenanigans in the data.

And you'd be surprised at how much traffic some roads get. Even some residential roads would see thousands daily. So if you really want to bump up the priority of the road, you would be better off driving over it all day, every day until it was removed; because you'd destroy your leg trying to stomp on it that many times. And you'd have to do this on all adjacent and feeder roads to support that data. And you'd have to ensure that you do this every year until you recognize the desired effects of your endeavor, and then you'd have to continue this practice in perpetuity. Or the jig is up!

You can also estimate the size of the vehicle. based on how fast it it going and the time between front and back wheel you could calculate the distance between the wheels.

with two strips you can get a lot more data than if you just have one. count, direction, speed, size, and times the road is active. I dont know if they active measure all that but its possible.

Good point about direction. I couldn't imagine using this for enforcement, but I'm guessing you could be pretty confident any the number of axels but counting the ones that are the exact same speed and by the distance apart.
