斜向路径的演化及其在城市中的应用

The Evolution of Diagonal Path and Its Application in Cities

斜向路径因其便捷、不绕路的特性而对步行出行具有重要意义。文章对斜向路径在西方城镇路网形态中的演变进行了梳理及斜向路径在现代步行中的应用进行了分析。研究发现建筑单元底层架空、公园和广场等公共空间及立体步行连廊系统可以设计形成斜向步行路径,方便行人穿越,实现步行的便捷、不绕路,减少步行距离、时间及推广街区制。斜向步行路径与轨道站点的结合可完善其附近步行网络、扩大其实际服务范围,解决当下城市蔓延导致的轨道站点密度不足的问题。

The diagonal path is of great significance for walking because of its convenient and non-detour characteristics.The paper sorts out the evolution of the oblique path in the form of western urban road network and analyzes its application in modern walking.The paper finds that the ground floor of the building unit,and the public spaces such as parks and plazas,and the three-dimensional pedestrian corridor system can be designed to form a diagonal pedestrian path,which is convenient for pedestrians to pass,reduce walking distance and time,and promote the block system.The combination of diagonal pedestrian paths and rail stations can improve the nearby pedestrian network,expand its actual service range,and solve the problem of insufficient density of rail stations caused by the current urban sprawl.
