The invention discloses a comprehensive evaluation method for multiple intersections and associated road sections of an urban road, and the method comprises the steps: 1, calculating the correlation index of the associated road sections, and dividing a plurality of intersection cells according to the correlation index of the associated road sections; 2, calculating a traffic saturation characteristic index of the multi-intersection district; 3, determining the weight of the associated road section, the weight of the target intersection and the weight of the road section by adopting an expert scoring method; 4, establishing a multi-intersection comprehensive traffic state evaluation model based on the association degree indexes of the associated road sections, the traffic saturation characteristic indexes of the multi-intersection districts and the related weights; and 5, determining multi-intersection comprehensive value domain division based on a multi-intersection comprehensive traffic state evaluation result. According to the method, the operation efficiency of the multiple intersections is reflected by the indexes, the target intersection and the associated road sections are comprehensively and integrally evaluated by dividing the multiple intersection cells, the management efficiency of a user on the multiple intersections is improved, and the overall management level is improved.
本发明的一种城市道路多交叉口及相关联路段综合评价方法,包括:步骤1:计算相关联路段的关联度指标,根据相关联路段的关联度指标划分多交叉口小区;步骤2:计算多交叉口小区交通饱和特征指标;步骤3:采用专家评分法确定相关联路段权重、目标交叉口权重、以及路段权重;步骤4:基于关联路段的关联度指标、多交叉口小区交通饱和特征指标以及相关权重建立多交叉口综合交通状态评价模型;步骤5:基于多交叉口综合交通状态评价结果确定多交叉口综合价值域划分。本发明用指标反映多交叉口的运行效率,通过多交叉口小区划分,综合整体评价目标交叉口及相关联路段,提高用户对于多交叉口的管理效率,提升整体管理水平。
