Quantitative Measure for Transportation Network Efficiency

A new quantitative measure for transportation network efficiency is proposed in this paper. The measure can be used to assess the performance of a transportation network, because it can reflect the influence on the network efficiency induced by flows, travel cost and travel behavior under the equilibrium of the transportation network. Numerical application denotes the method can measure the efficiency of the transportation network rationally, and the results of the measure accords to the practical situation.
