Top Contributing Factors

Collisions involving an animal remained the top contributing factor in both periods, with the count decreasing from 269 in 2021 to 256 in 2022. A significant change was observed in crashes due to 'Failure to yield right of way from a stop sign,' which fell by 35.7% from 56 to 36 incidents. Conversely, crashes where a driver 'Lost Control' increased by 27.3% in count, rising from 33 in 2021 to 42 in 2022, and moving from the fifth to the third most frequent factor.

Road & Environmental Conditions

The distribution of crashes across environmental conditions remained largely stable between the two periods. The majority of collisions in both 2022 and 2021 occurred in clear weather, during daylight hours, and on dry road surfaces. The absolute number of crashes in dark lighting conditions decreased from 140 to 115, and on non-dry road surfaces from 124 to 114, which aligns with the overall reduction in total crashes. The proportional share of crashes under these conditions did not change significantly.

Vehicles & Demographics

The most common vehicle makes involved in crashes, including Ford, Chevrolet, and Dodge, remained consistent across both years, with counts for each decreasing in 2022. A notable demographic shift occurred among persons involved in crashes. The 65+ age group became the largest cohort in 2022 with 221 individuals, increasing from 206 in 2021. In contrast, the 35-44 age group, which was the largest in the prior year with 234 individuals, saw its count drop to 196.

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: 669
  • Total persons involved: 1,408
  • Total vehicles involved: 971

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.
