为降低交通运输行业的碳排放规模、提高公交出行竞争力,从共享单车配置角度出发,提出可评估配置点位置对公交出行分担率影响的共享单车配置贡献系数,通过Logit模型计算OD全过程出行链下共享单车、“共享单车+公交”、私家车三种出行方式的分担率,探讨城市居民出行距离和共享单车配置贡献系数变化对公交出行竞争力的影响。算例计算结果表明:由于共享单车使用费与取还车附加时间的存在,共享单车配置贡献系数存在一临界值,高于该值时提高共享单车配置水平才可对公交出行竞争力提升产生积极影响;配置贡献系数临界值与端点接驳距离和公交出行距离呈负相关关系;由于私家车在长距离出行过程中的优势,当端点接驳距离为1km时,要维系“共享单车+公交”分担率不变,公交出行距离每增加1km,共享单车配置贡献系数需提高8.5%。研究结果表明,合理配置共享单车可提高公交分担率、扩大公交出行竞争范围。

In order to reduce the carbon emission scale of the transportation industry and improve the competitiveness of public transportation, the configuration contribution coefficient of shared bicycle was defined. The coefficient could evaluate the impact of allocation points of shared bicycles on bus travel. The sharing rates of shared bicycle, "shared bicycle plus bus" and private car were calculated under the OD travel chain through Logit model. The impact of travel distance and shared bicycle configuration coefficient on bus travel competitiveness was explored. The results showed as followed: due to the charge for use and additional time required to get and return the shared bicycle, there was a critical value for the configuration contribution coefficient of shared bicycle, when it was higher than this value, configuring shared bicycle could have a positive impact on bus travel competitiveness; the critical value of configuration contribution coefficient was negatively correlated with the end connection distance and travel distance; due to the advantages of private cars in the long-distance travel, when the connection distance was 1km, to maintain the sharing rate of "shared bicycle plus bus", the configuration contribution coefficient of shared bicycle needed to be increased by about 8.5% for every 1km increase in travel distance. The research shows that the rational configuration of shared bicycles can improve the bus sharing rate and expand the bus travel scope.
