Abstract: In order to break through the limitations of current dynamic traffic data from the Sydney coordinated adaptive traffic system(SCATS) applied only for dynamic signal control, from the perspective of information sharing, the dynamic traffic data collected from the inductive loop on SCATS were applied in the research of automated incident detection algorithm. The characteristics of the data collected from the inductive loop on SCATS were analyzed, and a new algorithm of automated incident detection (AID) based on the data was designed. The validity of the proposed AID algorithm was tested with measured data, and the new algorithm had a better performance on detection rate, false alarming rate and mean time to detection, it would be effective in improving the coordination in traffic signal control, traffic information guide and traffic command of roads covered by SCATS.

Key words: engineering of communication and transportation system, sydney coordinated traffic system(SCATS), automated incident detection(AID), inductive loop
