CTDOT Wrong‑Way Driving Detection System

Overview

Connecticut Department of Transportation (CTDOT) launched a comprehensive Wrong-Way Driving Detection System (WWDDS) program after 13 wrong-way crashes in 2022 resulted in 23 fatalities. The program aims to prevent wrong-way entries, improve response times, and gather reliable data to strengthen future interventions. Since implementation, wrong-way crashes have decreased significantly in Connecticut, dropping 61.5% by 2024 compared to 2022.
