Analysis of traffic flow reliability operation trend of urban road network under sudden disaster
Zhaosheng Yang · Journal of Jilin University · 2012
To identify the road network traffic flow reliability evolution and the potential trend under sudden disaster,the Rough set theory in combination with the urban traffic state identification and prediction knowledges were used to construct a knowledge representation system for the road traffic network reliability under sudden disaster.The logic reasoning of road traffic network reliability operation trend was realized through a series of operation processes,such as discretization of attribute data of the road traffic network elements,attribute and data reduction of the road traffic network reliability decision making table,etc.The experiment results demonstrated that the road traffic network reliability fits well with the traffic flow charactesistic under sudden disaster.The prediction accuracy of the proposed knowledge representation system for the road traffic network reliability reaches up to 90%.
