TY - JOUR PY - 2006// TI - Automatic Incident Detection Methodology for Freeway Using Floating Cars JO - Journal of Wuhan University of Technology (Transportation Science and Engineering) A1 - Zhang, Changsong A1 - Yang, Xiu-Chuan A1 - Yan, Xuedong SP - 973 EP - 975 VL - 30 IS - 6 N2 - Traffic incident detection is an important part of freeway emergency management system. It is reviewed researches of automatic incident detection methodology, analyzed the shortcoming of existing algorithms based on fixed detector, such as dissatisfied detection efficiency, restricted transplant capability, etc. A new incident detection methodology using floating cars' data is proposed according to the fact that incidents affect car speed obviously. The result shows that the new incident detection algorithm has high identification rate (92.5%), low false identification rate (1.2%) and short mean time to identification (1.6 min).
