土地利用政策是降低汽车依赖，促进绿色低碳出行的重要措施。因此，城市建成环境与出行行为的关系得到了广泛的研究。近年来，我国城市公共交通体系不断完善，都市圈也不断发展。这些发展趋势带来了居民出行行为的巨大变化。一方面，TOD站点区域逐渐成为居民日常活动的集中地。另一方面，都市圈及城际交通的建设促进了跨城出行的增加，极大的拓展了居民的出行空间范围。以往“土地利用-交通行为”的研究局限于单一城市，将传统社区作为基本空间单元，把TOD作为简单的建成环境要素来处理，因此难以与如今我国城市的发展趋势相匹配。本研究以TOD的视角来探究大都市圈的城市空间结构和居民出行行为的变化，将现有的“土地利用交通行为”研究，从以居住社区为基本空间单元向以TOD为基本单元转变，从单个城市尺度向都市圈尺度拓展。以粤港澳大湾区为典型区进行实证研究，研究结果将为新时期中国城市和交通体系建设提供科学决策依据。

Land use policies have been promoted as a potential strategy to reduce the car dependency and facilitate sustainable travels. As a result, the relationship between the built environment and travel behavior has widely been researched. In recently years, the public transport system continues to improve in many Chinese cities, and many metropolitan areas have been developed in China. These trends of urban development bring substantial changes in the travel behaviors of urban residents. On the one hand, TOD stations have gradually become the core areas for more and more people to satisfy their daily activities. One the other hand, the development of inter-city transportation system facilitates the travels between adjacent cities, thus greatly expands the activity space of residents. Most of previous land use-transport studies are limited to a single city. Besides, they typically take the residential neighborhood as the basic spatial unit of analysis, and consider TOD as a simple built environment attribute. Thus, the results of these research may not reflect the new trends of urban development in China nowadays. This research investigates the changes of urban forms and travel behaviors in the Guangdong-Hong Kong-Macao Greater Bay Area. It extends current land use-transport research from neighborhood-based to TOD-based, and broadens the spatial scale of analysis from a single city to the Greater Bay Area. The findings of our case study will provide important implications for the development of China’s urban and transportation systems in the new era.
