摘要:

针对目前城市群交通中普遍存在的供需关系不平衡问题,为探究其供需两者 之间的互馈机理,并揭示两者平衡的动态关系,构建城市群交通供需非均衡模型.首先,根 据对城市群交通供需关系的描述,明确城市群交通供给与需求平衡的内涵、研究范畴及 表现形式;其次,将城市群交通问题分为3 个部分,即城市群中单一城市内部、城市群中城 市与城市之间、城市群与外部之间,对城市群交通供给和交通需求的计算方法进行研究, 并根据两者的相互作用机制,利用微分动力学原理,构建城市群交通运输系统供需非均 衡模型;最后,运用微分方程的稳定性理论对模型进行求解,提出城市群交通供需的平衡 条件,并以呼包鄂城市群为实例来验证该模型的有效性和科学性.

Abstract:

Based on the imbalance between supply and demand which is common in current city agglomeration transportation, to research each feedback relation between traffic supply and demand, and reveals the dynamic relationship of them, this paper construct a non-equilibrium model of city agglomeration between traffic supply and demand. Firstly, According to the relationship between traffic supply and demand of city agglomeration, the connotation, research category and manifestation of city agglomeration traffic supply and demand balanced are cleared. Besides, the problem of city agglomeration transportation is divided into three aspects, which are the relation in single city of city agglomeration, the relation between city and city both of city agglomeration, and the relation between city agglomeration and outside, the computational method of traffic supply and demand of the city agglomeration are researched, according to the mechanism of the interaction of the two, a non-equilibrium model of city agglomeration between traffic supply and demand are constructed. Finally, according to the theory of stability of differential equation to solve this model, the balance conditions of traffic supply and demand are put forward, and an instance of Hubao’e agglomeration is given to verify the effectiveness and scientific nature of the model.

Key words: integrated transportation, non- equilibrium model, traffic supply and demand, city agglomeration, co-ordination of supply and demand
