When Crashes Happen
The temporal patterns of crashes remained largely consistent between the two periods. Friday was the peak day for crashes in both 2024 (359 crashes) and 2023 (330 crashes). Similarly, the 3 p.m. hour was the peak time for collisions in both years, though the count at that hour decreased from 156 to 141. The afternoon commute hours, from 3 p.m. to 5 p.m., consistently represented the time of day with the highest crash frequency across both years.

Top Contributing Factors
The leading contributing factor in both periods was "Followed too close," though its count decreased from 270 in 2023 to 250 in 2024. A significant year-over-year change was the reduction in crashes involving animals, which fell by 40.3% from 154 incidents to 92, dropping from the third to the fifth most common factor. In contrast, crashes attributed to "FTYROW: Making left turn" increased in count by 32.7%, from 49 to 65 incidents.

Road & Environmental Conditions
In both periods, the majority of crashes occurred in clear weather on dry roads during daylight hours, with the proportion of crashes in daylight remaining stable at around 63%. However, there was a notable increase in crashes occurring on adverse road surfaces. The count of collisions on wet, icy, snowy, or slushy roads rose from 304 in 2023 to 375 in 2024, driven by increases in crashes on icy surfaces (from 60 to 96) and wet surfaces (from 166 to 208).

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: 2024-01-01 through 2024-12-31
- Report generated: September 9, 2026
Data Coverage
- Reporting period: 2024-01-01 through 2024-12-31 (366 days)
- Geographic scope: iowa, IA
- Total crash records analyzed: 1,882
- Total persons involved: 3,457
- Total vehicles involved: 3,292
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.
