All day, most every person gets behind the wheel of their car—a dangerous act that has been deemed necessary to live and work. Unpredictable drivers, traffic patterns, weather, and roadway hazards can create dangerous driving conditions any time we’re on the road.
Motor vehicle crashes are the leading cause of death among those under age 55 in the US. 
Tennessee had the following total accidents :
- 2015 - 197,203
- 2016 - 206,409
- 2017 - 208,246
- 2018 - 208,605
The frequency of accidents is trending in the wrong direction. The CUIPs team of researchers wants to reverse the trend. We have the technology and data to positively impact the health and safety of our roadways, so we are seeking to learn how we can make Hamilton County drivers safer for everyone.
Our question became: How can these dangers be prevented or have their effects reduced?
Using historical 911 emergency call data, the CUIP is building a predictive model for roadway accidents. Historical and real-time 911 data, combined with weather and roadway geometric data, are used by these models so that the CUIP can help the Chattanooga Police Department best allocate officers and resources to high-probability areas. Identifying areas and conditions likely to result in roadway accidents and turning those insights into action leads to reduced response times, a reduction in accidents, and a safer Chattanooga.
Explore the model below to see our work. The darker the color and taller the gridblock tower, the more accidents that take place in that area. Use the slides on the right to explore accident trends by the hour, starting at midnight. Hours are in military time.
The CUIP studies current and historical 911 data to identify accident trends and cross-references this data with weather, roadway geometric data, accident time and date, and the accident’s latitude and longitude. This dataset is placed within a virtual grid of Chattanooga—where one gridblock roughly represents a 2x2 square of city blocks—and accident conditions and locations are identified as “hotspots” for accidents.
