New Jersey Department of Transportation’s Wrong Way Detection System

An average of 107 wrong way driving related crashes occur each year in the state of New Jersey. After detailed analysis of roadway geometrics, historical crash data, existing traffic control devices, and regional socio-economic factors, the New Jersey Department of Transportation targeted 11 sites along Route 1 and Route 295 for the installation of the state’s first Wrong Way Detection System. Aimed at identification, correction, and notification of wrong-way driving events, including motorcycles, the $18 million integrated solution leverages thermal imaging sensors and high-definition cameras to establish a two-point detection system to actuate localized or large-scale responses.  When the system positively detects a wrong-way driving vehicle, the localized response actuates the flash sequences on high-intensity sign panels intended to capture the driver’s attention and encourage corrective maneuvers before entering the mainline roadway. Within six months of system activation, 25 wrong way incidents were detected, with the technology successfully alerting the motorist to self-correct. The project is also piloting a software-based video-analytics platform capable of identification and tracking of wrong-way vehicles using existing CCTV camera feeds; providing New Jersey DOT a secondary level response to monitor verified wrong way driving events with no additional hardware cost.
