Method of Measuring the Capacity Flexibility of a Transportation Network
In the light of changes in supply chains and traffic patterns,and in the vulnerability of the network to both natural disasters and terrorist actions, flexibility was gradually desired as a characteristic of transport network. Concepts and techniques of the flexibility of transportation network were described to measure and accommodate the changing demands and traffic systems. It was emphasized on the graph network, which was used to measure the capacity of individual links, and nodes of a network in terms of volume-delay functions with methods already existed. Some approaches are described to measure the flexibility of the network. Applying a penalty to the model when it deviates from the underlying traffic pattern solves the issue of uniqueness of the available capacity. The result is shown to be valuable and applied.
