交叉口自行车交通服务品质评价方法及应用

Evaluation Method and Application of Bicycle Quality of Service at Intersections

交叉口是自行车骑行路径的控制节点,是决定骑行感受的重要组成部分。将交叉口自行车交通服务品质分为通过交叉口服务品质和交叉口区域待行服务品质两部分,从骑行者意愿和行为层面分析服务品质的影响要素。采集了上海市杨浦区21个典型交叉口67条进口道的设施特征,并对292名骑行者开展服务品质影响因素问卷调查,确定了评价指标的选取、量化分级和权重划分,采用聚类分析和层次分析等方法构建了交叉口自行车交通服务品质量化评价模型。研究表明:交叉口机动车流量、机动车专用右转车道设置、交叉口穿越距离以及进口道机非隔离形式是影响交叉口自行车交通服务品质的关键因素;其他影响因素还包括进口道宽度、铺面质量和遮荫条件等。最后,应用建立的评价方法,对上海市杨浦区典型骑行路径进行了服务品质评价与对比分析。

Intersections are the control nodes of cycling routes,and the crucial parts that influence the bicycle quality of service.The Intersection bicycle quality of service is divided into two parts:through quality of service and waiting quality of service.The paper analyzes the key factors affecting the quality of service from the cyclists’perception and behavior aspects.The selection of evaluation indexes,quantitative classification and weight division are determined based on the survey data of 67 approaches of 21 typical intersections in Yangpu District,Shanghai and the results of the questionnaire survey of 292 cyclists,thus establishing the grading evaluation method of intersection bicycle quality of service.The study reveals that the traffic volume of intersection,the existence of exclusive motor vehicle right turn lane,the crossing distance and the separation form of the approach are the significant factors.Other factors include the width of the approach,pavement quality and the shading conditions.Finally,based on the established evaluation method,the service quality evaluation and comparative analysis of the typical cycling routes in Yangpu District of Shanghai were carried out.
