宽容性理念在城市道路设计中的应用探讨

宽容性设计理念崇尚以人为本的道路容错、纠错功能，多用于高速公路路侧带的设计。而针对城市道路涵盖的交叉口、标志标线、防撞护栏及施工安全等多个方面的宽容性设计，目前国内的研究比较有限。为此，通过分析我国城市道路的设计现状，分别按城市道路施工区、城市主干道以及低流量交通道路几个方向提出了基于宽容性理念的设计建议，为加强城市道路安全提供具有实用性的设计参考。

Discussion on Application of Tolerance Concept in Urban Road Design

The concept of tolerance design advocates the function of people-oriented road fault tolerance and error correction, and is mainly used in the design of expressway side strip. At present, the domestic studies are relatively limited in the tolerance design of intersections, signs and markings, crash barriers and construction safety covered by the urban roads. Therefore, by analyzing the current design situation of urban roads in China, the technical advices based on the tolerance concept are proposed from the aspects of the construction zones of urban road, the urban trunk roads and the low-flow traffic roads in order to provide the practical design references for strengthening the safety of urban.
