In summer 2024, SC dept provided us with data about traffic accidents in SC for 6 years (2017 to 2022), covering various aspects such as location, occupant details, and vehicle information. The non-profit provided us data about student safety training in schools (called Alive@25). We used traffic data to understand traffic patterns and areas of improvement. We used Alive@25 to understand training coverage and gaps. Using both, and other public data like census and cost of accidents, we made recommendations to reduce road deaths and other accident costs. The project involved creating interactive visualizations to understand patterns in collision incidents across different county categories (Urban, Mostly Rural, Rural). Key insights included identifying high-risk urban counties, economic impact of collisions, observing trends in collision rates and Alive@25 program participation.

Analysis of Traffic Accident Data

Here we present three broad analyses of the traffic accident data, focusing on visualization, economic impact, and road conditions.

• Visualization of Traffic accidents over time and region - Collision incidents are higher in Greenville, Charleston, and Richland counties

• Analysis of Economic impact of accidents - Ratio of cost dealt to number of collisions is higher in mostly rural counties.


• Analysis of Road conditions and accidents - Collision incidents are higher in Two-way undivided road types.

Recommendations

• Recommendation 1 - Increase the count of two-way divided roads with barriers in Urban counties mainly focusing on Greeneville, Charleston, and Richland counties.
• Recommendation 2 - Increase the Alive@25 programs and conduct awareness camps in Mostly Rural counties.
