非均衡交通规划初探

传统交通规划以微观经济学瓦尔拉斯均衡原理作为理论基础 ,交通规划是针对市场均衡点进行展开的 ,不涉及非均衡区域 .实际上 ,均衡状态是一种特殊的非均衡 ,在一定的市场条件下才能实现 ,即使实现了 ,也是暂时的 ,它不能代表真实的市场情况 .鉴于运输市场非均衡的普遍存在性 ,本文根据非均衡理论及相关研究成果 ,提出了非均衡交通规划的思想 .通过对市场调控机制的分析 ,研究了运输市场非均衡的存在性 ;利用变分不等式对均衡与非均衡的统一性进行了等价描述 .提出了非均衡交通需求预测的思想 ,并将非均衡价格——数量调节行为原理引入到传统的用户路线选择行为之中

A primary study on disequilibrium transportation planning

The traditional transportation planning takes the microeconomics Walra s equilibrium principle as its theoretical base. Transportation planning is reve aled at the point of market equilibrium, and doesn't consider the market disequi librium cases. Actually, an equilibrium state is a special disequilibrium. Under some market conditions, an equilibrium case can be realized. However, these con ditions are very rigorous, we scarcely obtain them. Even if an equilibrium state is carried out, it is still temporary, and can't represent the real market. Tra nsportation market is usually in disequilibrium state. Based on the macroeconomi cs disequilibrium theory and pertinent research achievements, the idea of disequ ilibrium transportation planning is proposed in this paper. In order to establis h a basic theoretical framework, the existence of market disequilibrium is shown by analyzing the price and quantity regulation mechanism. The unified model of market equilibrium and disequilibrium is introduced by virtue of variational ine quality. In this paper, the concept of disequilibrium degree is also posed, and the method for disequilibrium traffic demand forecasting is proposed by incorpor ating the disequilibrium degree. Finally, the price-quantity regulation princip l e of macroeconomics disequilibrium theory is introduced into the user's route ch oice behavior, a more general behavior principle is proposed as a result.
