When Crashes Happen
The timing of crashes showed some shifts between the two periods. In 2016, the peak days for crashes were Tuesday and Friday, each with 54 incidents, a change from 2015 when Saturday was the peak day with 57 crashes. However, the evening commute hour remained the most common time for a crash, with the 5 p.m. hour being the peak in both 2016 (28 crashes) and 2015 (27 crashes). December was the month with the highest crash volume in both years, with 52 crashes in 2016 and 51 in 2015.

Crash Severity Breakdown
Crash severity levels improved from 2015 to 2016, although the number of fatal crashes remained constant at two, representing 0.6% of all crashes in both years. The proportion of crashes resulting in any level of injury decreased from 23.6% in 2015 (79 crashes) to 18.5% in 2016 (60 crashes). This was driven by a drop in serious injury crashes from 17 to 10 and minor injury crashes from 37 to 27. Consequently, the share of no-injury crashes rose from 75.8% to 81.0% year-over-year.

Top Contributing Factors
Collisions with animals remained the leading contributing factor in both years, with a nearly identical count of 127 crashes in 2016 compared to 128 in 2015. While the top factor was stable, there were significant shifts in other driver-related behaviors. Crashes attributed to 'Driving too fast for conditions' increased by 64.7% in count, rising from 17 incidents in 2015 to 28 in 2016. Conversely, crashes due to 'Followed too close' decreased by 63.6% (from 11 to 4), and incidents of 'Ran Stop Sign' fell by 75% (from 8 to 2).

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: 2016-01-01 through 2016-12-31
- Report generated: September 9, 2026
Data Coverage
- Reporting period: 2016-01-01 through 2016-12-31 (366 days)
- Geographic scope: iowa, IA
- Total crash records analyzed: 326
- Total persons involved: 475
- Total vehicles involved: 422
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.
