Integration of Transportation Systems into Compact City Design

定量分析了直达交通排除对典型路网格局的影响，阐明了考虑直通交通可达性和非直达交通的有效街道模式；比较了需求响应型交通(DRT)与固定路线(如铁路、公共汽车)和自由路线(如私家车、自行车)的出行时间特征，提出了DRT可用的需求密度条件，并根据人口密度提出了最优系统。利用基于行人网络数据库的地理信息系统，分析了主要车站周边区域的步行空间分布特征。此外，我们还研究了为容纳聚集在车站附近的人流所需的行人空间数量。

This study quantitatively analyzed effects of through traffic exclusion on the typical road network pattern, and elucidated the efficient street pattern considering trade-off between accessibility and exclusion of through traffic.We figured out the characteristic of travel time in the demand responsive transport (DRT) compared to the type of fixed route (e.g., railway, bus) and the type of free route (e.g., private automobile, bicycle), and suggested the condition of demand density where DRT is useful, and the optimal system in accordance to the population density. We also analyzed the distributional characteristic of pedestrian spaces in around areas of major stations by using GIS based on the pedestrian network database. Furthermore, we examined the necessary quantity of pedestrian spaces to accommodate the flow of people congregating in the neighborhood of stations.
