摘　　要：为了从多角度准确地评价城市信号交叉口人行横道对行人的服务水平,选择了速度、密度、饱和度和延误四个关键指标,并以长春市部分信号交叉口为例,通过Tracker软件对行人轨迹进行跟踪,获取数据。引入了无量纲化的概念对指标进行处理,使指标与服务水平同趋势化。运用层次分析法确定指标权重,根据不同指标对服务水平的影响将多指标转化成为一个综合指标,进而对服务水平进行综合评价。研究成果可以为城市交通规划和基础设施改善提供科学合理的决策支持,以促进城市交通系统的可持续发展。To accurately evaluate the service level of urban signalized intersection crosswalks on pedestrian level of service from multiple perspectives,the paper selects four key indicators:speed,density,saturation,and delay.Taking some signalized intersections in Changchun as a case study,the study uses Tracker software to track pedestrian trajectories and gather data.The introduction of dimensionless processing aligns the indicators with the trend of the service level.The Analytic Hierarchy Process(AHP)is applied to determine the weights of these indicators.Considering the varied impact of different indicators on the service level,multiple indicators are transformed into a composite index through AHP,enabling a comprehensive evaluation of the service level.The research findings are expected to provide scientifically sound decision support for urban traffic planning and infrastructure improvement,contributing to the sustainable development of urban transportation systems.
