【摘要】 为提高城市道路接入口交通安全水平与通行效率,构建接入口布局评价因素集,以道路特性、建筑特性、土地特性和驾驶员特性为二级因素集,以道路通行能力适应性、交通安全适应性、用地面积协调性、地块形状协调性、沿街面协调性、周边用地情况协调性、驾驶员心理压力等要素为一级因素集,在此基础上,通过隶属度计算,进行一级和二级模糊评价,最后以某市城市道路接入口布局方案为例,进行成果试算。本文提出了城市道路接入口布局多级模糊评价方法,为城市道路交通规划提供一定的理论参考。更多还原

【Abstract】 To heighten the traffic safety level and travel efficiency of urban street access, the evaluation factor aggregation of access layout was established. Features of street, building, land and driver were taken as the second factor aggregation, and the adaptability of street capacity, adaptability of traffic safety, coordination of land use area,coordination of land shape, coordination of street side, coordination of adjacent land use and psychological pressure of drivers were considered as the first factor aggregation. Based on these factors, through calculating the membership degree, the first and second grade fuzzy evaluations were proposed. Finally, schemes of urban street access layout in one city were used for example, as a trial calculation of research results. The multilevel fuzzy evaluation method of urban street access layout put forward by the paper could provide some theoretical reference for the urban street traffic planning.更多还原
