本文分两部分回顾了由Beckmann，McGuire和Winsten最初描述的具有弹性需求的交通分配问题的表述、解释和求解方法。本文第一部分定义了网络中不同可能的交通分配模式，并确定了相关极值公式的经济原理。随附的论文第二部分研究了计算结果流型的算法方法。分配问题被描述为运输系统的用户和运营商之间的相互作用，类似于市场中消费者和生产者之间的相互作用。因此，“用户最优化”和“系统最优化”的概念得到了一致的解释，由全系统的最大化目标来表达。
This study reviews, in two parts, the formulation, interpretation, and solution methodology of the traffic assignment problem with elastic demands, originally described by Beckmann, McGuire and Winsten. This paper Part I defines the different possible modes of traffic assignment in a network and identifies the economic rationales of the associated extremum formulations. The accompanying paper Part II examines algorithmic approaches for calculating the resulting flow patterns. The assignment problem is characterized as an interaction between users and operators of the transportation system, analogous to the interaction between consumers and producers in the marketplace. The notions of “user-optimization” and “system-optimization” thus acquire congruent interpretations, expressed by a systemwide maximization objective.
