Top Contributing Factors
The leading contributing factors for crashes shifted between 2019 and 2020. In 2020, 'Lost Control' was the most cited factor with 13 incidents, an increase from 11 incidents in 2019. Conversely, crashes attributed to 'Failure to Yield Right of Way at an uncontrolled intersection' saw a count-based decrease of 64.3%, falling from 14 incidents in 2019 to 5 in 2020. The count of crashes involving 'Driving too fast for conditions' more than doubled, increasing from 3 to 7 year-over-year.

Road & Environmental Conditions
The conditions under which crashes occurred remained largely consistent, with the majority of incidents in both years happening in daylight and clear weather. However, there was a notable shift in road surface conditions, as the number of crashes on adverse surfaces like snow, ice, or wet pavement was cut in half, from 30 in 2019 to 15 in 2020. Consequently, the share of crashes on dry roads increased from 61.7% in 2019 to 67.1% in 2020.

Vehicles & Demographics
The types of vehicles involved in crashes were similar year-over-year, with Chevrolet and Ford remaining the two most common makes in both 2019 and 2020, though their total counts decreased in line with the overall reduction in crashes. An analysis of persons involved shows that the 16-20 age group was the most represented demographic in both periods. This group's share of total persons involved increased slightly from 15.3% in 2019 (33 of 215 people) to 17.1% in 2020 (26 of 152 people).

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: 2020-01-01 through 2020-12-31
- Report generated: September 9, 2026
Data Coverage
- Reporting period: 2020-01-01 through 2020-12-31 (366 days)
- Geographic scope: iowa, IA
- Total crash records analyzed: 70
- Total persons involved: 152
- Total vehicles involved: 108
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.
