01 / The gap

Nobody checks whether the plan happened

Permits, plow routes, signal retiming, contractor hours, vendor promises. All written down. Almost none of it gets checked.

A road that measures itself turns a promise into a receipt, and a receipt reaches whoever signs the check.

02 / How it works

The hard part is not losing the thread

A pylon is a street light that also measures traffic. Coverage overlaps. The next pylon sees an object before the last one loses it.

A count you can trust needs that thread to hold across an intersection. We built that part.

Fig 01

How coverage overlaps between pylonsA three-lane road seen from above. Four pylons stand along one side. Each pylon covers an oval of road under it. Each oval overlaps the next, so the road is covered end to end with no gap between pylons. An object in an overlap is seen by two pylons at once. One object crosses the whole stretch. It pulls out into the next lane and back. It is drawn as one unbroken line. It carries one number. That number is retired when the object leaves.4417How coverage overlaps between pylonsA three-lane road seen from above. Two pylons stand along one side. Each pylon covers an oval of road under it.

Four pylons. Their coverage overlaps. One object crosses, and we retire its number when it leaves.

03 / Privacy

We track movement. We never learn who

We follow every vehicle, bike and person, live, with no gaps. We never learn who any of them is.

  • No plate reader. Nothing in a pylon turns a plate into a name.
  • No face recognition. We never built one into a pylon.
  • No history. We retire a shape's number the moment it leaves coverage. We never issue that number again.

04 / Today

Nothing is on a public road yet

No revenue yet, and no outside money. Building toward a first deployment.
