Crash locations for the year 2021. ODOT’s crash data system uses the OH1 Report provided by DPS and law enforcement agencies around the state to compile crash data and break it down by different attributes. These attributes are used in AASHTOWare Safety crash analysis tool to summarize crash trends around the state.
Questions answered with this data
- Color every state-highway segment by its fatal and serious-injury crash rate per 100 million vehicle miles over 2021–2025, in quintiles, and mark the worst 25 stretches on top.
- For the MORPC area around Columbus, compute fatalities, serious injuries, each as a count and as a rate per 100 million vehicle miles, and non-motorized fatalities and serious injuries, for each of the last five years, and map where they fall.
- For the MVRPC metropolitan planning area around Dayton (the MVRPC polygon in the MPO data set, which covers Montgomery, Miami, Greene and the northern part of Warren County), count fatal and serious-injury crashes for each year from 2021 through 2025, counting each crash report once by its crash severity. Use the same scope as MVRPC's Safety Action Plan: leave out crashes on restricted-access freeways (functional class 1 and 2, which covers I-70, I-75, I-675 and the freeway sections of US 35 and SR 4), crashes on freeway ramps, and crashes with no location. Split each year into urban and rural, where urban means inside ODOT's Adjusted Urbanized Areas. Show one table with a row per year and columns for urban fatal, rural fatal, urban serious injury, rural serious injury, and total fatal plus serious injury. Then show a second table, by year, of the fatal and serious-injury crashes that the freeway and ramp exclusions removed. Map the counted crashes colored by severity, draw the excluded freeway crashes in gray, and outline the MVRPC boundary and the urbanized areas.
- The NOACA area around Cleveland has $10 million for safety improvements on state routes. Choose where to spend it to prevent the most fatal and serious-injury crashes, using 2021–2024 crashes and two countermeasures. The first is centerline and shoulder rumble strips at $25,000 per mile, which cut lane-departure crashes by 30% on two-lane segments posted 45 mph or higher. The second is roundabouts at $2 million each, which cut angle crashes by 60% at intersections. Rank candidates by crashes prevented per dollar, pick the best mix within the budget, and map the chosen segments and intersections with the expected crashes prevented at each.
