Wrong Turn Violation Detection System

One of the most common causes of accidents in flowing traffic is incorrect turns at forbidden points.
A2-Enforcement No Turn Violation Detection System has been developed by a2 Technology engineers in order to automatically detect vehicles that do not comply with the turn prohibition rules, at points where violations occur frequently and where needed, in order to minimize accidents and prevent loss of life and property.

It is fully compliant with the current General Requirements and the Type Specification published by the General Directorate of Security. The system has Type Approval and Certificate of Turkish Standards Institution. This system has been tested and approved by the Turkish Standards Institution, National Police and an internationally accredited laboratory. It works actively at many points.

a2-Enforcement No Return Violation Detection System includes Violation Detection Camera and Evidence Camera. These cameras scan continuously within the field of view. Every passing vehicle is detected, and a violation scenario is run through motion analysis. As soon as the violation is detected, the videos and photos of the faulty vehicle are recorded in the system and a violation file is created and sent to the a2-Backoffice central software.
a2-Backoffice queries the vehicle on National Database and generates an audible and visual alarm if there is any record like such as loss, stolen, suspect.
