For traffic operations engineers and technicians
The warrant study that eats your whole day? done in five minutes.
Run all nine MUTCD warrants, multi-way stop and AWSC/TWSC analyses directly in your browser. Use counts already in the system. The result: a sealed PDF with every threshold, rolling hour, and pass/fail decision fully documented.

Watch: counts to sealed verdict in 60 seconds.
You know how this goes.
A resident calls about the side street. A council member forwards a petition for a four-way stop. A developer's TIA lands on your desk with a signal recommendation you don't quite believe.
And now the question is yours: what does this intersection actually need?
So you pull the counts from one system. Export. Reformat. Re-type them into the spreadsheet you inherited from the engineer before you. Open the MUTCD to check whether the template even matches the current edition. Build the rolling hours by hand. Check Warrant 1, condition A, then condition B. Then Warrant 2. Then the other seven.
Somewhere around hour six you realize the counts pasted one row off.
The answer was probably obvious by lunchtime. Proving it, in a form that survives the reviewer, the council meeting, and a records request two years from now, is what eats the day.
TraffIQ exists to give you that day back.
How it works
Counts in. Sealed verdict out. Five minutes.
STEP 1
Your counts are already here.
If you run Game|Changer, turning-movement counts flow into your account from the field automatically, every 15 minutes. No Game|Changer? Import your TMC file, or key counts in by hand. Either way: no export-reformat-retype shuffle.
STEP 2
Every control question, one pass.
Nine MUTCD 11th Edition signal warrants (2009 supported). The five multi-way stop criteria of 2B.13–2B.17. AWSC and TWSC control delay and LOS per HCM Chapters 20 and 21. Each warrant returns MET, NOT MET, or REQUIRES JUDGMENT, with the controlling condition and the numbers behind it.
STEP 3
A study that can't quietly change.
One click produces the report: warrant-by-warrant results, hourly evidence tables, cited thresholds, seal block. Sealed reports are checksummed and immutable. Drafts are watermarked UN-SEALED so nothing ambiguous ever leaves the building.
Don’t trust us. Hand it to your toughest reviewer.
TraffIQ is new. The math isn't.
Judge the deliverable first
Download a real sealed report and hand it to your toughest reviewer. Warrant-by-warrant results, hourly evidence, the seal block. If it wouldn't survive your review process, close this tab.
The methodology is on screen
Conditions side by side. Thresholds printed in the open. Every rolling hour with its pass/fail. A Methodology reference one click away in every module. Nothing is a black box, because your reviewer won't accept a black box.
128+ automated tests
Every engine is validated line by line against its source chapter, MUTCD criteria and HCM equations, and re-verified on every release.
Same inputs, same outputs. Forever.
The engine is deterministic. Re-run any study two meetings or two years later and get the identical answer. When someone asks "is this the version that was stamped?", the checksum answers in one click.
The Match-My-Answer Guarantee: Run an intersection you’ve already studied by hand. If TraffIQ doesn’t reach the same verdict against the same MUTCD and HCM math your reviewer uses, we want to hear about it. No credit card, no risk, nothing to install - just proof.
The founder letter
Why I built this
As a traffic engineer myself, I've spent the past 20 years building tools that make our profession more effective - from In|Sync® in 2007, which transformed adaptive signal control, to Game|Changer® in 2018, which transformed traffic data collection.
But one thing never changed. As traffic data became faster and easier to collect, signal warrant studies remained trapped in spreadsheets. Engineers still spent hours assembling reports for conclusions they often reached within minutes.
TraffIQ closes that gap. It takes the counts already in your system, runs them against the same MUTCD and HCM methodology your reviewers expect, and produces a sealed study in minutes. That's not a marketing claim - it's the problem we set out to solve.
Try it free for 30 days. Run an intersection you've already analyzed and compare the results. If it reaches the same conclusion in a fraction of the time, we've done our job.

Your 30-day evaluation starts the moment you register and create an organization. No credit card needed. Evaluation reports carry an UN-SEALED watermark - sealing activates with your license. Once a user from your organization purchases a license, the evaluation period ends for everyone in the organization.
Same standards. A different day at work.
| THE TRAFFIQ WAY | THE DESKTOP WAY | TIME PER STUDY | ✓Minutes: analysis runs against counts already in the system | ✕The better part of a day: export, reformat, re-type, then analyze |
|---|---|---|
| COUNTS IN | ✓Game|Changer counts flow in automatically - or import your turning-movement counts, or enter them by hand | ✕Count data exported from one tool, reformatted, and re-typed into another |
| PLATFORM | ✓Browser-native: any OS, nothing to install, one per-seat subscription | ✕Windows desktop installs, licensed per workstation |
| MODULES | ✓All four analysis modules in every license: Signal Warrants, MWSC, AWSC, TWSC | ✕Warrant analysis sold as a separate add-on module |
| TEAM WORKFLOW | ✓Technician, engineer and admin roles in one shared project, with a full audit trail | ✕Single-user and file-based - studies get emailed around for review |
| REPORT ARCHIVE | ✓Just sealеd PDF, checksummed and immutable; unsealed drafts watermarked UN-SEALED and flattened | ✕Editable PDFs scattered across local folders |
| MUTCD EDITION | ✓11th Edition (2023), with 2009 legacy support | ✕Varies by tool - some current, some still on 2009 |
| UPDATES | ✓Continuous - every login is the current version | ✕Patch installers, version by version, machine by machine |

Same math the standards publish. A completely different day at work.
Less than one billable day - every module included
Less than one billable day - every module included.
One kicked-back study costs weeks of re-review, a missed council meeting, and a records-request scramble two years later. TraffIQ is one license, every module, for less than a single billable day.
$3,500
first year, per seat, one-time initial fee, first year included
$1,000 / year
after that, flat, the price stays put
All four modules. Unlimited studies. Every future module included.
One license = one seat. Buy multiple seats in one checkout.
Public sector: POs accepted. For most agencies, $3,500 fits inside the micro-purchase or P-card threshold. No procurement odyssey.
Your 30-day evaluation starts when you register. No credit card. Evaluation reports carry an UN-SEALED watermark; sealing activates with your license.

Questions Engineers Ask (FAQ)
Will my reviewer accept it?
The thresholds and equations are the MUTCD's and the HCM's, cited chapter and section, printed in the report next to every result. Download the sample report and hand it to your reviewer before you spend a minute in the app. If they won't accept it, don't sign up.
We already have a warrant tool.
The desktop tools compute the published math correctly, and so do we. The difference is everything around the math: whether counts arrive by pipe or by re-typing, whether the study is sealed and immutable or an editable PDF in a shared folder, and whether warrant analysis is included or a paid add-on.
We don't have Game|Changer.
Import your TMC file or enter counts by hand. The analysis, the evidence tables, and the sealed report are identical. Game|Changer just removes the import step, every 15 minutes, automatically.
What does IT need to approve?
Nothing to install, nothing on-prem. It runs in the browser. One per-seat subscription, no per-workstation licensing, no patch installers.
Is my data locked in?
Your counts and reports are yours. Reports are PDFs you keep; sealed copies are checksummed precisely so they stay valid outside our system.
What happens after the 30 days?
The evaluation ends for your whole organization when any user buys a license, or quietly expires. Nothing auto-bills; there is no card on file to bill.
The next petition is already in someone's outbox.
When it lands, you can open the spreadsheet and lose the day. Or open TraffIQ, run every warrant against counts that are already there, and hand back an answer that sticks.
