Dynamic core theory and its application in traffic management and control

For the goal of realizing to control urban road traffic flow to reduce congestion and obstruction, and perfecting the theories of the dynamic core and its application in the traffic management and control, this paper proposes the concepts of the dynamic core and coritivity of the dynamic flow network system, and the method of calculating the core and coritivity of the directed connected network system. According to this graph theory, this paper further proposes the simple methods of calculating the dynamic core and coritivity of the traffic network system. Finally, this paper uses numerical examples to illustrate the application of calculating the dynamic core in the traffic management and control.
