基于扩展节点-场所模型的北京轨道微中心地铁站点评价与分类

Evaluation and classification of Beijing rail microcenter subway stations based on extended node-place model

节点-场所模型通过关注交通和土地特征的平衡,为评估公共交通导向开发(TOD)提供了有效的框架。在传统节点-场所模型的基础上,增加可步行性作为新的评价维度,定量描述站点地区的步行网络可达性与设施可步行性,提出了节点-场所-可步行性扩展模型。基于多源数据与地理信息系统技术(GIS),利用扩展模型对北京轨道微中心地铁站点进行了评估和分类,并与传统节点-场所模型评价结果进行比较。结果表明,节点、场所与可步行性之间存在明显的协同作用,站点的发展水平存在较大差异,并且新模型与传统节点-场所模型相比可以更加全面地评价地铁站点。

The node-place model provides an effective framework for evaluating TOD by focusing on the balance of traffic and land characteristics.Based on the traditional node-place model,the node-place-walkability extended model was proposed by adding walkability as a new evaluation dimension to quantitatively describe the accessibility of pedestrian network and walkability of facilities in the site area.Based on multi-source data and GIS technology(GIS),the extended model was used to evaluate and classify Beijing rail microcenter metro stations and compared with the evaluation results of the traditional nodeplace model.The results show that there is an obvious synergy between nodes,places and walkability,that there are large differences in the development levels of stations,and that the new model can evaluate metro stations more comprehensively compared with the traditional node-place model.
