Top Contributing Factors

Collisions with animals remained the leading contributing factor in both periods, though the count of such incidents decreased by 30% from 70 in 2021 to 49 in 2022. "Lost Control" became a more prominent factor, with its crash count increasing from 7 to 16, moving it to the second-ranked cause in 2022. Conversely, factors like "Followed too close" (from 16 to 6 crashes) and "Failure to yield from a stop sign" (from 13 to 5 crashes) saw significant decreases in their counts.

Road & Environmental Conditions

The proportion of crashes occurring in clear weather and daylight conditions remained stable year-over-year at approximately 55% and 50%, respectively. However, there was a notable shift in crashes related to adverse road surfaces. The share of crashes on dry roads decreased from 52.2% in 2021 to 46.0% in 2022. Concurrently, crashes on icy or frosty roads increased from 3 to 13, and those on snowy roads rose from 10 to 14, indicating a greater impact of winter conditions in 2022.

Vehicles & Demographics

Ford and Chevrolet-affiliated makes (Chev, GMC) were the most frequently involved vehicles in crashes in both 2021 and 2022, though their total counts decreased in line with the overall trend. In terms of persons involved, the 26-34 and 35-44 age groups were highly represented in both years. Notably, the number of persons aged 65 and older involved in crashes increased from 48 to 53, making it one of the top two most-represented age groups in 2022.

Data Sources & Methodology

Primary Data Source

All crash data in this report is sourced from Iowa Crash Data, accessed programmatically via the ArcGIS Open Data API (SODA). This dataset contains official police-reported motor vehicle traffic crash records maintained by the reporting jurisdiction's law enforcement agency. Records are published to the open data portal by the municipality and are subject to the portal's terms of use.

Data Retrieval

  • Access method: ArcGIS Open Data API (SoQL queries)
  • Data format: Structured JSON via REST API
  • Record types queried: Crash events, person records, and vehicle unit records
  • Date filter applied: 2022-01-01 through 2022-12-31
  • Report generated: September 9, 2026

Data Coverage

  • Reporting period: 2022-01-01 through 2022-12-31 (365 days)
  • Geographic scope: iowa, IA
  • Total crash records analyzed: 163
  • Total persons involved: 358
  • Total vehicles involved: 231

Analytical Methodology

  • Severity classification: Uses the KABCO injury scale (K=Fatal, A=Incapacitating injury, B=Non-incapacitating injury, C=Possible injury, O=No injury/property damage only), the standard classification in U.S. Model Minimum Uniform Crash Criteria (MMUCC). Severity is assigned per crash event based on the most severe injury in that crash. A single fatal crash (K) may involve multiple fatalities; therefore the "Persons Killed" count in the headline KPIs may differ from the "Fatal" crash count in the severity breakdown.
  • Contributing factors: Reflect the officer-determined primary contributory cause recorded at the time of the crash report. These are preliminary determinations and may not reflect final investigation findings.
  • Hit-and-run classification: Based on the hit-and-run indicator field in the official crash report, as determined by the responding officer at the scene.
  • Temporal analysis: Day-of-week and hour-of-day distributions are computed from the crash date/time timestamp in each record.
  • Demographics: Age and sex distributions are drawn from person-level records linked to each crash event. A single crash may involve multiple persons.
  • Vehicle data: Make information is drawn from vehicle unit records linked to each crash event.
  • AI commentary: Narrative sections are generated by Google Gemini (large language model) based on the structured data. Commentary is descriptive, not predictive, and should not be interpreted as expert opinion.

Limitations & Disclaimers

  • Only crashes reported to and documented by law enforcement are included. Minor incidents, unreported crashes, and near-misses are not captured in this dataset.
  • Data reflects conditions at the time of the initial police report and may be subject to subsequent corrections, reclassifications, or supplements by the reporting agency.
  • Open data portal records may experience a publication lag - recently occurring crashes may not yet appear in the dataset at the time of report generation.
  • AI-generated commentary is produced by a large language model and is intended to highlight patterns in the data. It does not constitute legal, medical, or professional analysis.
  • Percentages are calculated from reported data and are subject to rounding.
