摘要：常用的城市路网分级体系存在局限性，导致道路横断面设计以 “车”为本，过于强调道路的“通道”功能，而忽视人们活动的“场所”功 能。为解决这一问题，对现行基于城市路网垂直分级体系(快速路、主 干路、次干路、支路)的道路横断面设计方法进行分析，提出“两类(街与 道)五级(商业街、景观街、生活街和主道、次道)”的城市路网水平分级体 系和考虑道路两侧土地利用、空间环境、交通运行、公交优先和慢行保 障五方面因素的道路横断面设计方法，并将该方法应用于无锡市蠡溪 路。实施结果表明，基于城市路网水平分级体系的道路横断面设计方 法，使道路充分发挥车辆出行的“通道”功能和人们活动的“场所”功能， 实现了城市道路设计中“以人为本”的目标。

Abstract：The current cross-section design follows the widely accepted urban roadway network classification system that overemphasizes capacity of corridor with top priority to vehicular traffic movement, and ignores non-motorized traffic activity needs. To address this problem, this study analyzes the current roadway cross-section design based on urban road network hierarchy classification system (expressway, major corridor, minor corridor, and collector), and proposes a new cross-section design method based on a new urban roadway classification system that considers two types of roadway (highway and street) and five categories (commercial street, sight-seeing street, residential street, main street and minor street). The new cross-section design also considers roadside land-use development, environment, traffic operation, transit priority and nom-motorized traffic. The results from a demonstration project on Lixi Road in Wuxi city show that the new design method can not only provide mobility to vehicular traffic but also satisfy the needs of non-vehicular traffic, which helps greatly in accomplishing the society human oriented objective.
