广州城市空间结构与交通需求关系

在综述国内外相关研究的基础上,以广州为案例研究城市空间结构与交通需求的关系。结果表明,在城市形态与交通需求的关系方面,广州城市二维形态和三维形态与交通需求的空间分布之间具有一定的耦合性,二者存在一定互为因果的关系;交通方式的转化对城市形态的演化具有一定的驱动作用;城市形态引导着交通需求的总量和布局;同时,社会经济活动及其发展是城市形态与交通需求产生的原因和相互联系的纽带。在城市内部空间结构与交通需求的关系方面,模型分析表明,近年来广州城市内部居住与就业的空间均衡性增强,直接影响了交通需求的产生与分布和交通方式的选择,有利于居民就近选择就业,并使通勤交通的空间分布更加均衡;此外,居住与就业人口迁移先行,引导公共设施的发展也是近年来广州城市发展的主要特征之一;公共设施服务空间与交通需求之间存在需求作用型和供给作用型两种相互作用模式。

The Relationship between Urban Structure and Traffic Demand in Guangzhou

By using new techniques and model analysis, a case study on the relationship between urban structure and traffic demand in Guangzhou was carried out. The results show that there are certain relationships between the development of urban form and traffic demand. Firstly, the model of urban traffic ways is one of the reasons for shaping the urban forms. Secondly, the urban form directs the distribution of traffic demand. Finally, the factors of social and economic development have important impacts on both the urban forms and urban traffic demand, and their reciprocity. Meanwhile, there are also certain relationships between the urban structure and traffic demand. The balance of residents and industries is one of the factors affecting the selection of traffic ways and the distribution of traffic demand. At the same time, there are two models, e.g. demand oriented and supply oriented, concerning the relationship between urban commercial land use and traffic demand. The demand oriented one means that location is one of the most important factors affecting the commercial environment.
