摘要
绿色出行引导效果受外部信息及出行者选择偏好影响,需要考虑出行者潜在属性类别的异质性。自我呈现表现为人们通过控制与自己有关的信息来影响他人对自己的印象,体现了信息与选择偏好的交互作用。为定量分析出行者自我呈现意识和环保意识对出行方式选择行为的影响,本文通过问卷调查收集到1382份有效样本,利用潜在类别模型(Latent Class Model,LCM)将出行者划分为高自我呈现组(18.23%)、中自我呈现组(20.26%)和低自我呈现组(61.51%)。离散选择模型的结果表明,出行者在进行方式选择时更关注出行时间和出行方式自身的特性,若不考虑方式特性,会高估出行费用对高自我呈现组的影响。高自我呈现组仅在短距离出行中对公共交通有强烈偏好,对于6~10 km的出行,选择私家车倾向明显。中短距离的出行中,低自我呈现组对骑行的偏好价值可以在一定程度上抵消过长出行时间带来的负效用。构建考虑出行者异质性的方式选择模型,可为政府和相关部门制定更协调、有针对性的交通调控政策及公共交通运营策略提供理论依据。
The effectiveness of"green travel"guidance is influenced by external information and travelers'choice preferences.The heterogeneity of potential attribute categories of travelers needs to be considered.Self-presentation manifests itself as people influencing others'impressions of themselves by controlling the information that relates to them,which reflects the interaction of information and choice preferences.To quantify the influence of travelers'selfpresentation awareness and environmental awareness on mode choice behavior,1382 valid samples were collected through a questionnaire survey.The latent class model(LCM)is used to classify the travelers into high selfpresentation group(18.23%),medium self-presentation group(20.26%)and low self-presentation group(61.51%).The results of the discrete choice model suggest that travelers pay more attention to travel time and the characteristics of the travel mode itself when making mode choices.The effect of travel expense on the high self-presentation group would be overestimated if mode characteristics are not considered.Travelers from the high self-presentation group have a strong preference for public transit only for short-distance trips,and their tendency for private cars is obvious for trips of 6 to 10 kilometers.The preference value of the low self-presentation group for cycling can offset to some extent the negative utility of excessively long travel times in short to medium distance trips.The construction of a mode choice model that considers travelers'heterogeneity can provide a theoretical basis for the government and related departments to formulate more coordinated and targeted regulation policies and public transportation operation strategies.
