Abstract:

 quantitative evaluation method for the road transportation network efficiency was proposed to grasp the effects of the traffic demand, the sectional traffic flow, and the travel sideeffect,etc., on the network efficiency. Based on this method, a method for evaluating the importance level of the network components was developed to distinguish the important modes and links in the network. The method has been vesified by a practical example and is characterized by the simplicity of calculation and the agreement of the calculated results with the practical data. It was found that the network efficiency the network component importance level are related to the traffic flow in the network.

Key words: engineering of communications and transportation, road transportation network, network efficiency, network component, importance level evaluation
