Wrong Way Warning System

Our patented wireless collaboration integrates data from multiple radar detectors, resulting in an unparalleled level of reliability.


Dual Radar Collaboration

Powered by our intelligent mesh network, our patented Dual Radar Collaboration technology syncs data from up to 8 radars to for near-perfect detection and instant response times. 

+Notification System

Real-time video notifications are swiftly transmitted via 4G networks, with personalized email, text, and web notifications tailored to your team's preferences. 

"TraffiCalm is recommended as the most effective WWPS after considering ... accuracy, responsiveness, live-tracking, life-cycle cost, and other relevant elements."

-Tennessee Department of Transportation

Case Study

An independent study conducted by the Tennessee DOT found that the TraffiCalm Wrong Way Prevention System had a 99% detection accuracy.

Case Study: Systemic Approach to Prevent Wrong-Way Driving

This study proposes a comprehensive systemic approach to mitigate wrong-way driving incidents, particularly focusing on the typical profile of wrong-way drivers. The recommendations encompass various engineering countermeasures, considering factors such as signage, pavement markings, active warning signs, geometric modifications, and lighting. Statistical data and references to LED lighting and RRFB usage are integrated where applicable.
