城市景点的公共交通出行便捷性指数: 基于武汉市的调查研究

为弥补城市景点公共交通便捷性评价主客观分离缺陷，以单个游客出行链为研究对象，以游客个体特征，公共交通出行链和景点吸引力这3个层面的因素为自变量，游客感知便捷程度为因变量，采用武汉市15个主要景点的问卷数据建立多项Logistic和CI(Convenience Index)模型。利用回归系数分析因素的影响，用标准化系数分析各因素对感知便捷性的影响权重，用CI模型计算武汉市景点的公共交通出行便捷性指数。结果表明：非机动出行距离与骑行分担率具有显著交互效应，非机动出行距离小于0.408 km时，更适宜步行出行；将公共交通出行链因素按对感知便捷性的影响权重由大到小排序，正向影响为地铁分担率、骑行分担率，负向影响为非机动出行距离、换乘次数、总出行距离、非直线系数；武汉市不同景点的公共交通出行便捷性指数差异明显，指数最高的景点是楚河汉街，最低的景点是东湖绿道-磨山。

Convenience Index of Public Transportation for Urban Tourist Attraction: Based on Investigation in Wuhan

In order to compensate for the defect of subjective- objective separation in the evaluation on the public transportation convenience for urban tourist attractions, this paper took the factors of tourist's individual characteristic, public transportation travel chain and attractiveness of the tourist attraction as the independent variables, and the perceived convenience level of tourists as the dependent variable based on a single travel chain of each tourist. The questionnaire data from 15 major tourist attractions in Wuhan were collected to establish the Multinomial Logistic and Convenience Index (CI) model. The regression coefficient was used to analyze the influence of each factor, the standardized coefficient was used to analyze the influence weight of each factor on the perceived convenience level, and the CI model was used to calculate the convenience indices of public transportation for urban tourist attractions in Wuhan. The results show that: (1) There is a significant interaction effect between non-motorized travel distance and cycling sharing rate, and it is more suitable to walk when the non-motorized travel distance is less than 0.408 km. (2) Factors of public transport travel chain are ranked from the largest to the smallest according to their influence weight on perceived convenience level-positive influence: subway sharing rate, cycling sharing rate; negative influence: nonmotorized travel distance, transfer times, total travel distance, non-linear coefficient. (3) The public transportation convenience indices of different tourist attractions in Wuhan are different significantly, the Chu River Han Street's convenience index is highest and the East Lake Greenway-Mount Mo's convenience index is lowest.
