For accident surveillance and traffic flow conditions, CCTV cameras are installed on bridges. However, their effectiveness is diminished remarkably in a thick fog. Despite heavy fog, the proposed system can detect a car crash on the bridges and propagate accident information to other drivers as quickly as possible to reduce the accident rate and casualties. The authors designed the system not only to detect car crashes and propagate accident information to reduce accident rate, but also to acquire traffic information and atmospheric information. The Safe & Intelligent Bridges System collects RFID (Radio Frequency IDentification) Tag data by using RFID middleware called ALE (Application Level Event).
