ZeqTraffic

Traffic signal optimization and flow modeling. Zeqond-timed green wave synchronization, congestion prediction, accident probability scoring using R(t) vehicle density.

Protocol IDzeq-traffic
CategoryWater, Traffic, Bridge, Power Grid, Smart City
Version1.287.0
Endpoint/api/infra/traffic 🔵 POST
AuthenticationRequired (Bearer API key)
Rate Limit20/min

Purpose​

Traffic signal optimization and flow modeling. Zeqond-timed green wave synchronization, congestion prediction, accident probability scoring using R(t) vehicle density. It belongs to the Water, Traffic, Bridge, Power Grid, Smart City family and is callable as a single REST endpoint, a one-line SDK call, or via streaming where applicable.

What it does​

When you call /api/infra/traffic, Zeq runs the ZeqTraffic computation through the KO42 metric tensioner under the active HulyaPulse phase. The result is sealed at the next Zeqond boundary (0.777 s) and returned with a verifiable ZeqProof receipt — meaning the same inputs at the same phase always produce the same output, and any third party can later verify the result was computed at the time you claim.

In practice, this protocol takes the parameters listed below, performs its water, traffic, bridge, power grid, smart city operation, and returns a structured response containing the computation output plus phase-locking metadata (zeqondTick, hulyaPhase, zeqProof).

When to use it​

Reach for ZeqTraffic when you need a water, traffic, bridge, power grid, smart city primitive that:

  • Must be reproducible — every call is deterministic for a given phase
  • Must be auditable — every response carries a tamper-evident ZeqProof receipt
  • Must compose with other Zeq protocols — outputs are phase-aligned to 1.287 Hz so they slot directly into downstream calls without resync
  • Must scale across domains — the same endpoint works whether you're driving one call per minute or part of a high-throughput pipeline (subject to rate limit 20/min)

If you only need a one-shot water, traffic, bridge, power grid, smart city answer with no audit trail and no composition with other Zeq calls, a plain library may be cheaper. If you need any of the four properties above, this protocol is the right tool.

How to call it​

The fastest path is a single HTTPS POST request to /api/infra/traffic with a Bearer token. You can use cURL, JavaScript, Python, or any HTTP client — examples for all three are below. The response is JSON.

Parameters​

No required parameters. Send an empty JSON body {} or include domain-specific fields.

Returns​

{ signalTimings, greenWaveSpeed_kmh, congestionScore, accidentRisk, zeqond }

How to call it — every language​

Every Zeq endpoint is a plain HTTPS POST. That means you can call it from any language that speaks HTTP. Below: thirteen working snippets — pick whichever fits your stack.

Phase-Locking & ZeqProof​

Every response from /api/infra/traffic carries:

  • zeqondTick — the Zeqond (0.777 s) at which the result was sealed
  • hulyaPhase — the HulyaPulse phase ∈ [0, 1) at sealing
  • zeqProof — HMAC receipt that lets any third party verify the result without an API key via POST /api/zeq/prove/verify

See Concepts → ZeqProof and HulyaPulse for the underlying mathematics.
