摘要

摘要: 针对城市居住与工业混合用地街区步行与机动车交通的矛盾,基于空间句法原理,建立了一组定量分析空间移动属性的模型,并应用于长沙天心经济开发区一个混合用地样本区的步行道优化设计。调研数据表明:样本区内部道路机动车交通流量与路网的空间移动属性显著相关;局部步行人流量与步行路网的空间移动属性为弱相关,呈现为外围街道集聚而内部街道隔离的空心状态。提出了2个步行道布置优化方案,并对现状和优化方案进行了比较分析。结果表明,增加过街通道有利于步行人流的通过性,增加步行路网的密度有利于步行人流的可达性。空间移动属性的分析方法可有效评判步行道组构的合理性,有助于实现宜居兴业、产城融合的城市需求。

Abstract: To resolve the contradiction between pedestrian and motor vehicle traffic in mixed urban residential and industrial land-use blocks, this study established a set of models for the quantitative analysis of spatial movement based on the principle of space syntax. These were applied to the optimal design of walkways in a mixed land sample area of the Changsha Tianxin Economic Development Zone. The investigation data showed that the traffic flow of motor vehicles in the sample area was significantly related to the spatial movement attribute of the road network; the local pedestrian flow was weakly related to the spatial moving attribute of the pedestrian network which presented a hollow state of peripheral street agglomeration and internal streets isolation. Two optimization schemes of walkways layout were put forward, and the current situation and the optimization schemes were compared and analyzed. The results showed that increasing the street crossing was beneficial to the pass-through ability for pedestrians, and increasing the density of the walkways network was beneficial to the accessibility for pedestrians. The spatial movement attribute analysis method could effectively evaluate the rationality of walkways structure and help to realize the urban demands for improving the living and business enviroment and production-city integration.
