Low Visibility Detection Service

Vizzion's traffic camera analytics service utilizes existing DOT infrastructure to create valuable visibility data for both navigation apps and traffic management centers.

Vizzion's Low Visibility Detection Service proactively scans a global network of over 65,000 live traffic cameras to detect unsafe driving conditions such as fog, smoke, or heavy precipitation. The service outputs georeferenced polygons outlining locations of low visibility for easy integration into traffic management centers and driving-focused apps – allowing drivers to be automatically alerted or re-routed for their safety.

According to the Federal Highway Administration, over 25,000 accidents per year in the US involve fog, resulting in about 400 fatalities annually. In fact, a quarter of all car accidents are weather related, causing avoidable injuries, fatalities, and hundreds of millions of dollars in damage. Currently, fog is difficult to forecast and expensive to detect. Forecasting fog with visibility less than half a mile is only 30% accurate and most forecasting is focused around airports for aviation purposes rather than for drivers. Several state transportation departments (DOT’s) have invested heavily in hardware along roadsides with costs ranging from $100,000 for detection at a single intersection in West Virginia, up to $12 million for 13 miles of roadway coverage by Caltrans near Fresno. These systems typically communicate to drivers by flashing “Fog Ahead” warning lights or Variable Message Signs (VMS) which are statically positioned and may not allow drivers to take the appropriate action in time.
