One platform, three surfaces
Field crew records on iPhone or Android. Desk engineer analyzes in the portal. Client gets a report they can defend. Everything syncs itself in between.
Mobile app
Collect on the phone
Drive the corridor and tap START. Driver-glance header, auto-direction reversal, Quick Collect, keep-awake, and offline-first sync — the data is right before you get back to the office.
Web portal
Analyze in the workbench
Time-Space Diagram, Speed/Distance plot, travel-time distribution with PTI/BTI/LOTTR, delay breakdown, platoon arrival, and a confidence panel that tells you when you've driven enough runs.
Reports
Deliver defensible reports
Before/after PDF with executive summary, Welch's t-test significance, reliability KPIs, and economic impact — plus multi-sheet Excel and four CSV variants. Watermark-aware trial mode for previews.
Everything in the box
From the pulsing START button to the multi-tenant plumbing that keeps studies from getting lost.
iPhone or Android, no dedicated hardware
Pulsing mint START button, driver-glance header, auto-direction-reversal, and offline-first sync. The driver never takes eyes off traffic.
- Auto-detects U-turns and starts the paired-direction run
- Quick Collect mode for new corridors with zero pre-config
- Keep-awake during recording — phone won't sleep mid-run
- Auto-sync after every run, plus a tappable badge to retry
Analysis surface engineers actually trust
Time-Space Diagram with median + percentile bands. Speed/Distance plot. Travel-Time Distribution histogram with PTI, BTI, LOTTR.
- Delay Breakdown stacked by moving / stopped-queue delay
- Platoon Arrival per signal (HCM Arrival Type 1–6)
- Confidence panel with Z-based sample-size calculator
- Auto length-validator rejects runs that didn't drive the corridor
Defensible client deliverables
Before/After PDF report with executive summary, Welch's t-test significance, reliability KPIs, economic impact, methodology.
- PDF, Excel (.xlsx) multi-sheet, and four CSV variants
- Watermark-aware trial mode for prospect-side previews
- Engineer / client / prepared-by metadata on the cover
- Dollar figures convert engineering metrics into client-fundable language
The boring stuff that saves the study
Three-phase post-sync pipeline runs on every push: segment analysis → time-period classification → length validation. Each in its own transaction.
- 8-table relational schema with soft deletes
- Bidirectional dirty tracking — nothing silently lost
- JWT auth, role-based access, multi-tenant org separation
- UTDF timing-plan upload with effective_from / effective_to dating
From run to client report in three steps
Drive the corridor
Open the app, tap START. The driver-glance header tracks elapsed time, signals passed, GPS accuracy. Auto-reversal handles the return leg.
Sync to the portal
Park, and the run uploads itself. The desk engineer sees it in real time in the portal — no USB sticks, no email.
Export the report
Workbench computes reliability, platoon arrival, economic impact. One click yields a branded PDF, Excel, or CSV the client can defend.
Standards your client recognizes
No black-box scores. Every number traces to a published method.
Industry-standard speed bands
Speed-banded GPS dots and a 13-metric segment table — the visual conventions traffic engineers already trust on signal-timing study reports.
FHWA reliability
PTI = p95/p50, BTI = (p95−p50)/p50, LOTTR = p80/p50. LOTTR ≤ 1.5 maps to the 23 CFR 490 reliable-segment threshold.
HCM Arrival Type
Per-signal AT 1–6 from Rp = (1 − stop rate) ÷ (g/C). Date-aware UTDF plan match — BEFORE and AFTER studies pick the right plan automatically.
Economic impact
USDOT BCA value-of-time, EPA Social Cost of Carbon, CalTrans ICF criteria-pollutant rates, NCHRP cost-per-stop. Editable per organization.
