摘　　要：针对街道建成环境对自行车出行的影响进行精细化评估,能够合理引导非机动车道与自行车专用路建设,有效指导城市街道空间治理。构建街道建成环境对自行车出行的影响评价体系,包含客观物质环境和主观情绪感受两个维度共11项评价指标,并提出各指标的计算方法和影响关系分析方法。以成都市环城生态区一级环城绿道为例,以共享单车出行数据为研究样本来表征自行车出行特征,分析街道建成环境对自行车出行的影响。结果显示:环生区自行车交通网络客观物质环境指数平均值仅为35.1分,表明路权保障和道路基础设施配套是影响自行车出行选择的首要条件;客观物质环境和主观情绪感受与自行车出行高度相关,且主观情绪感受影响更强;工作日和周末不同出行目的自行车出行路径选择呈现高度相似性,重合比例高于75%,表明自行车交通网络建设应强化客观物质环境与主观情绪感受的衔接。A refined assessment of how the street built environment affects bicycle travel can reasonably guide the development of non-motorized lanes and dedicated bicycle routes,and effectively inform urban street space governance.This paper presents an evaluation framework to assess the influence of the street built environment on bicycle travel,incorporating 11 evaluation indicators from two dimensions:objective physical environment and subjective emotional perception.The methods for calculating each indicator and analyzing the influence relationship are proposed.Using the primary ring greenway in the Chengdu Ring Ecological Zone as a case study,shared bicycle travel data are employed as the research sample to charac-terize bicycle travel patterns and analyze the impact of the street built environment on bicycle travel.The results have shown that the average score of the objective physical environment index for the bicycle trans-portation network in the Ring Ecological Zone is merely 35.1,indicating that right-of-way protection and roadway infrastructure are the primary factors influencing bicycle travel choices.Both the objective physi-cal environment and subjective emotional perception exhibit a strong correlation with bicycle travel,with subjective emotional perception having a greater influence.In addition,bicycle travel paths for different travel purposes on weekdays and weekends have high similarity with an overlap rate exceeding 75%,un-derscoring the need for enhanced integration between objective physical environment and subjective emo-tional perception in bicycle transportation network development.
