Annual performance
How service performed over time. Annual summaries use the selected year; combined legacy activities retain their original reporting scope.

Demand
Where recorded crashes concentrate. Review corridor demand before interpreting response performance.

Detailed chronology: 2025-01-01 to 2026-09-15 · all corridors · 134,382 events matching the operational filters. Earlier years contain annual summaries only.
Time patterns
When incidents occur. Compare hourly demand and weekday averages within the available filter detail.
The busiest recorded hour starts at 15:00 Eastern (10,822 incidents). Thu has the highest observed weekday average at 250.8 incidents per included day.
Incident time uses the first chronology entry. Daily rates exclude boundary dates, daylight-saving transitions and missing days.
Response
How quickly Road Rangers arrived. Read response coverage, incident-type performance and event records together.

Response = same-unit notification to arrival; unmatched pairs excluded. Zero-minute intervals may reflect self-discovery. Differences do not isolate staffing, distance or incident complexity.
2026 is partial. Historical chronology only; earlier response summaries are in Operations. Rankings are descriptive, not forecasts.
Traffic context
How traffic conditions relate to incident demand. These associations provide context rather than evidence of cause.

Matched month/corridor/hour groups

UrbanSDK coverage: 2026-08, 2024-05. Historical aggregate correlations; speed and TTI may contain overlapping information.
Traffic profiles use year, month, corridor and hour; incident counts also use event type. County-specific traffic relationships are unavailable. Each month/corridor/hour group contributes one observation. Corridor and time effects may confound correlations; no causal or advance-warning effect is established.
Predictor readiness
Which evidence is available, which inputs can support modeling, and where the data still has gaps.
Predictor availability
| Factor | Available evidence | Prediction use |
|---|---|---|
| Historical location & temporal context | Compare corridor, hour, weekday and seasonal demand. | Included in time-tested count models. |
| Severity | 134,382 known ATIS categories; 24,523 intermediate/major. Severity is assigned after the event. | Descriptive only; not a pre-incident feature. |
| Response performance | Measure observed notification-to-arrival intervals. | Operational outcome; not an incident-risk input. |
| UrbanSDK speed, TTI & Collision Index | Compare historical traffic context where periods overlap. | Not used in current forecasts; short coverage and index provenance limit as-of validation. |
| ActiveVision & live congestion | Analyze API event mix and reported status separately. | No time-aligned pre-incident detector history yet. |
| Weather, geometry & lighting | Current weather and road geometry are available for context. | No matched historical weather, lighting or pavement training table. |
| Secondary crashes & lane blockage | Not reliably labeled in the current processed snapshot. | Cannot estimate secondary-crash probability or reduction yet. |
