主 题：Boundary distance evolution security region transportation network TransCAD.
摘 要：This paper proposes a security region of transporta-tion networks,which is defined as the set of flow states(operating points)satisfying the N-1 security in transportation *** boundary of the set is closed,inside all the operating points are N-1 secure;oppositely,outside all the operating points are ***,N-1 security of the transportation networks is defined,which means that when a road is blocked,vehicles on other roads within the networks can also reach their destination through different paths without being trapped on the ***,the security region of transportation networks is *** algorithm of a boundary calculation is studied and the boundary equations of security distances are ***,the proposed security of the transportation networks is presented in different *** paper demonstrates the following:1)the security region can be accurately predicted by the simulation of N-1;2)the boundary distance can show the necessary degree of security;3)security can be improved by a preventive control *** simulation on TransCAD is used to verify the correctness of the *** Terms-Boundary distance,evolution,security region,transportation network,TransCAD.
