Methodology
This is the whole method, in the order it happens. If your evaluation team wants to walk it stage by stage with our operations lead, we will do that on a call rather than make you infer it from a diagram.
Before the queue
We do not decide what needs human review — you do. Transactions route to us on your OCR confidence threshold, so the boundary between automated and manual processing stays under your control and can be tuned as your read rates improve.
A transaction typically arrives with the full capture, the ALPR’s proposed read, its confidence score, and the lane and gantry metadata. Where multiple frames exist we take all of them, because the best frame is frequently not the first one.
Trusted, exempt and sensitive vehicle lists are applied at intake. Matches are auto-dispositioned or routed to restricted handling before they can ever appear in a general reviewer’s queue.
The six stages
The plate is isolated from the full vehicle capture. Where several frames exist, the reviewer works from the most legible rather than the default.
Skipped: reviewers squint at full-frame captures, review times triple, and marginal plates get coded off that were recoverable.
Contrast, brightness, deskew and glare handling applied to a working copy. Your original capture is never altered, so the audit record always points back to the untouched source.
Skipped: night-time retroreflective washout and low-angle captures become unreadable that a two-second adjustment would have recovered.
Two reviewers independently identify the issuing state or province, neither able to see the other’s entry. Jurisdiction is settled before characters.
Skipped: the characters are keyed correctly against the wrong state, and the bill goes to a real person who does not own the vehicle. This is the error that generates complaints and disputes.
Two further reviewers independently key the characters, validated against your configured character set, plate types, prefixes, suffixes and permitted special characters.
Skipped: single-read entry. Every character confusion pair — 0/O, 8/B, 5/S, 2/Z — becomes a billing error at whatever rate that individual reviewer happens to make them.
Every disagreement between blind reads, and every plate proposed as unreadable, goes to a supervisor for final disposition. There is no path by which one reviewer’s entry becomes billable on its own.
Skipped: disagreements resolve by whoever keyed first, or by majority guess, and the disagreement itself — your best signal about image quality — is never recorded.
The transaction returns with a disposition and, where not billable, a reason code from a set configured with you. The full action history stays attached to the record.
Skipped: you get a pile of rejects with no explanation, and the camera fault generating them keeps generating them next month.
The point of it
Four independent reads is not thoroughness for its own sake. It is the only way to produce an accuracy number you can defend in an audit — because the disagreements between reads are themselves the measurement.
After the queue
Thirty minutes, stage by stage, with your questions rather than our slides.
