摘　　要：研究了交通网络分配中用户平衡模型的内在涵义，引入管道网中流体平衡的比拟，依据最小势能原理，提出一种直观地解释和建立用户平衡模型方程的方法，并用该方法分析了几种典型的用户平衡模型．最后探讨了进一步研究交通网络的性质和用户平衡模型机理的可能性．he analytical approach draws on analogies between users' equilibrium in transport networks and water equilibrium in pipe networks, when traffic assignment and users' equilibrium have been studied essntially. Based on these anologies and the minimum potential energy principle, the mathematical programming equations of users' equlibrium can be established and interpreted intutively, as illustrated by the analysis of some typical users' equilibriums. The idea is extended to some questions deserving further study, such as to find a final interpretation of users' equilibrium by economic or behavioral theory or the conception of extropy.
