【摘要】：在住房市场化与城市规模不断扩张的背景下,大城市居民出行时间增长,交通拥堵问题日益严峻。中观尺度空间作为一种特定尺度的城市空间,其功能与空间结构优化对减少居民出行距离、提高交通效率有重要意义。以武汉市关山口街区为研究案例,将出行需求作为核心因素,以减少私人长距离出行为导向,结合街区的空间布局特征,采用问卷调查法,分析街区居民出行行为的数量、类型和频率,指出2km是居民出行活跃程度的临界尺度,该尺度在非机动出行可接受的范围内,但仍存在大量长距离、高频率的工作出行。中观尺度空间的规划布局应注重2km尺度内匀质的功能混合,将一部分的长距离出行内化于非机动出行可接受的尺度范围内。最后,从交通与功能空间协调的角度提出大城市中观尺度空间布局优化的建议策略。
[Abstract]:Under the background of housing marketization and the continuous expansion of urban scale, the travel time of residents in large cities is increasing, and the traffic congestion problem is becoming more and more serious. As a special scale of urban space, mesoscale space is a special scale of urban space. The optimization of its function and space structure is of great significance to reduce the travel distance of residents and improve the traffic efficiency. Taking Guanshankou block in Wuhan as a case study, taking travel demand as the core factor and reducing private long-distance travel as the direction, Based on the spatial layout characteristics of the block, this paper analyzes the number, type and frequency of residents' travel behavior by questionnaire, and points out that 2km is the critical scale of residents' travel activity, which is within the acceptable range of non-motorized travel. However, there are still a large number of long distance and high frequency working trips. The planning and layout of mesoscale space should pay attention to the homogeneous functional mixing within 2 km scale, and internalize part of the long distance travel within the acceptable scale range of non motorized travel. Finally, From the point of view of coordination of traffic and functional space, this paper puts forward some suggestions for the optimization of mesoscale spatial layout in large cities.
