In Stockholm, Sweden, drivers have been testing an IBM system of radio frequency transponders and roadside cameras aimed at reducing traffic during peak hours.
The optical character recognition system in roadside cameras around Stockholm is designed to read license plates in different light conditions and from various angles. If a toll payment cannot be made through a windshield RFID transponder, or if driver information is uncertain, the system compares front and back plates.
