| Abstract: | According to the fact that researches of automatic incident detection mainly focus on freeway and expressway,and data resource is usually single,this paper brought forward an approach of urban road AID(Automatic Incident Detection) based on multiple data fusion technology.This paper analyzed the change of traffic flow caused by incident under traffic signal control,after preprocessing the data from floating car,SCATS,and Citilog systems in Hangzhou City,and the paper then built differential flow rate and average velocity AID model based on the CUSUM algorithm which can suppress the periodic influence on traffic flow.The system of AID consists of two modes including video judgment and traffic parameters analysis and three indexes which comprise differential flow rate,average velocity and travel time.The experimental results showed that during peak hours and non-peak hours,the model could detect traffic incidents rapidly and accurately. |
