Abstract
The methods for measuring the efficiencies of transportation networks with fixed and elastic demands are proposed, respectively. The measures reflect the influences of travel behavior, travel cost, travel demands and link flows, all in equilibrium state, on network efficiency. Based on the definition of network efficiency, the approach for ranking the importance of the network components is developed. Numerical examples show that the method of measuring network efficiency and the approach for ranking network components are effective. The Braess paradox network with varied demand is analyzed, and the importance of the nodes and links are computed. The proposed methods and conclusions are guide for designing and managing the transportation networks.
