道路分隔带迎交通流端头的标识设置探讨

Discussion on the Sign Setting at the End of the Road Separator Facing the Traffic Flow

道路分隔带端头的交通标志和标线看似简单,却屡屡因为其设置不合理而导致发生交通事故。尤其在城市道路的交叉口,这类事故更为常见。通过分析分隔带端头设置不当的类型及原因,结合我国现行相关的标准、规范要求和工程实践经验,提出了各种不同类型分隔带端头的合理设置方案,如按照分隔带的不同宽度分为一般情况、过宽和过窄3种情况,对机非分隔带因地块开口需要断开以及临近交叉口需要增设机非分隔带的情况,特别是针对易发生交通事故的各种情况给出了具体的设置方案,并对相关规范提出了修改建议。

Traffic signs and markings at the end of the road separator looks simple,but they have repeatedly cause traffic accidents due to their improper installation.Especially at the intersection of urban roads,more accidents occur.The types and reasons of improper setting of the end of the separator are analyzed in this paper.Combined with the current relevant standards,specifications and engineering experience,a variety of different types of reasonable program are put forward.According to the dfferent widths of the separator,it is divided into three types of general situation,too wide and too narrow.Under the condition that the opening of the plot should be disconnected and the separator between motor and non-motor should be set at the intersection,especially for the traffic accidents prone to all kinds of situations,a specific setting scheme is made as well as changing suggestions.
