In October 2015, 400 of these ITS systems were delivered to 200 locations across Bulgaria's road network. They perform a continuous traffic count, vehicle classification (10 categories, e.g. passenger car, motorbike, truck), speed detection and number plate recognition for vehicles travelling at a speed of up to 200 km/h in up to two lanes. Featuring a recognition accuracy of more than 95 % for Bulgarian number plates, the systems are installed on purpose-made gantries and triggered by a ground contact in the road. At the heart of this system is Carrida, a very fast and precise ANPR software from Germany-based embedded imaging expert Vision Components, a long-term partner of atto-Systems.
