| Abstract: | Based on the core and coritivity of the non - directional connected network system, this paper proposes the method of calculating the core and coritivity of the directional connected network system, and applies it in calculating the dynamic core and coritivity of the dynamic flow network system. This paper also sets forth that the traffic network system is the dynamic flow network system, and it possesses the characteristics of generic dynamic flow network system. Finally, this paper presents the algorithm of calculating the dynamic core and coritivity of the traffic network system which can be used to solve the problem of calculation of the crossways and supervise traffic jam and congestion in cities. |
