Abstract:

This paper is based on the results of transportation research projects. The factors affecting the development of transportation are analysed, and the working program for the project is given out. A general formula which is the combination of “system optimization” and “user optimization” are proposed, and it can be used to design the equilibrium transportation network of multi-object, multi-style and multi-goods. These methods are also applied to studying problems of railway and highway transportation system for national level and provincial level. A partly optimized algorithm is also developed to solve the nonconvex programming question.

Key words: transportation network, optimization, equilibrium, mathematical model
