轨道交通网络化条件下宜居型TOD发展模式优化研究

目前公共交通导向的发展模式已经受到广泛重视。许多城市在进行TOD规划设计和开发建设时往往侧重于对轨道站点地区的空间设计特征的控制，而缺少对城市空间结构和轨道交通网络特征的深入分析。在我国城市空间结构和轨道网络日益复杂化的情况下，这种策略对促进TOD模式发展和宜居城市建设的作用如何仍然值得探讨。国内外研究表明除站点地区设计特征外，城市的空间结构特征和轨道的网络属性都会对轨道交通作用的发挥产生影响。本研究按照宜居城市的发展目标，构建宜居型TOD发展模式的评价体系；选择典型案例城市的旧城与外围新建地区进行居民出行链和宜居性调查，通过多元数据融合技术、空间分析、统计分析和模拟模型研究城市空间结构特征、轨道网络特征和站点地区的空间设计特征对站点客流和宜居性的影响，并进行综合评价，结合国内外的案例分析，探讨在轨道交通网络化条件下宜居型TOD规划建设的理论，以指导我国城市规划的实践，促进宜居城市的建设。

Transit oriented development model has been widely accepted in urban planning practice. Many cities usually just focus on the spatial planning and design around the urban rail transit station area, detail analysis on urban spatial structure and urban rail transit network always being ignored. With the increasing complexity of urban spatial structure and extensive urban rail transit network in China, the effect of this strategy on developing TOD mode and promoting the livable city is worth discussing. Researches show that besides the design features of urban rail transit station area, the spatial structure of the city and the network attributes of the urban rail transit network and station will have an impact on the effect of rail transit on urban development. Based on the target of developing a livable city, this paper constructs the index system to evaluate the livability of TOD model. We will carry out survey on the residents' livability in both old area and new area of the city. Then we will study and evaluate the impact of characteristics of urban spatial structure, the characteristics of the railway network and the spatial design characteristics of the station area on station passenger and urban livability by means of multivariate data fusion, spatial analysis, statistical analysis and simulation model. The planning theory for livable TOD model will be explored on the condition of extensive urban rail transit network to urban planning practice to promote livable city development.
