[Study] The Most Dangerous Intersections in Missouri

Kansas City Dangerous Intersections

While road safety has improved dramatically in recent years, intersections can still be a dangerous place for drivers.  In fact, thousands of people are injured in motor vehicle collisions at intersections throughout the state of Missouri every year.

Which intersections in the state present the greatest risk to drivers? Our team of personal injury attorneys in Kansas City, MO worked with data visualization firm 1Point21 Interactive to help us analyze nearly 150,000 crash records to find out.

Together, we analyzed collision data from the Missouri State Highway Patrol in 2018 (the latest full year available), isolated all crashes that occurred at an intersection, and applied a weighted score to each crossing based on how serious the injuries were in each crash.

Below, we identify the most dangerous intersections in Missouri.

[Interactive Map]

The map below is interactive.  Use the mouse wheel or touch gestures to zoom in and out. Each circle on the map represents an intersection where at least six collisions occurred in 2018. Hover over or click the circle to reveal more information.

Most Dangerous Intersections

Dangerous intersections are defined in this study as crossings where both a high number of collisions and injuries occur.  Whether it’s due to dangerous conditions, traffic volume, or any other factor, drivers at these intersections are more likely to be involved in a serious collision.

As the basis of our study, we identified 577 intersections where six or more crashes occurred during the study period, then accounted for the number and severity of injuries incurred in those crashes.

Based on this methodology, the most dangerous intersection in Missouri is Oak Street and Truman Road in Kansas City.

This intersection saw 28 crashes and 29 total injuries in a single year, the most injuries and second most crashes of any crossing in our study.

Kansas City, in fact, was home all of the three most dangerous intersections and four of the top ten.

30 Most Dangerous Intersections Missouri

The table below includes more information and lists the 100 most dangerous intersections in Missouri, along with the total number of crashes, injuries, and fatalities.  Intersections are ranked by their Crash Risk Index score (CRI), a figure that weighs both collision volume and injury severity. The higher the CRI score, the more dangerous that intersection is. Only intersections where six or more collisions occurred were considered to be included in the list.

Total by Intersection Type

Which types of intersections involve the highest rate of injury? We found that drivers should be extra cautious when using four and five-way intersections.

  • 4-Way Intersections: 58% of crashes involve injuries
  • T-Intersections: 44% of crashes involve injuries
  • Roundabouts: 16% of crashes involve injuries
  • Y-Intersections: 36% of crashes involve injuries
  • 5-Way or more: 62% of crashes involve injuries
  • Others: 47% of crashes involve injuries

The table below shows the statistics for crashes at each intersection type.

IntersectionType Crashes Minor Injuries Major Injuries Total Injuries Fatalities
4-Way 20257 10966 779 11743 90
T-Intersection 7778 3188 262 3450 49
Other 1100 460 58 519 4

Y-Intersection 403 132 14 146 3
5-Way or more 245 150 2 152 1

Study Notes

Our study does not take traffic volume into account due to figures not being readily available for every intersection in the state during the entire time period.  While we agree that the level of traffic at each crossing is important, we also believe the collision and injury volume is a very good indicator of danger.  It stands to reason, intersections with more crashes are more dangerous than those with fewer crashes.

We feel that this list can help drivers understand the risks on the road around them and adjust their routes or driving behaviors accordingly to keep them safe.
