Studies have applied single-reference-point or safety margin hypotheses to examine how advanced traveler information affects travel behaviors. However, these theories may fail to fully capture the trade-offs among origin departure time, airport access time, and terminal processing time in terms of airport ground access behaviors. In this study, we developed a tri-reference-point hypothesis and assumed that the rate of change of utility may change at the air passenger’s preferred (PAT), earliest acceptable (EAT), and latest acceptable (LAT) airport arrival times. With an empirical data set collected from 304 passengers at Taipei Songshan Airport, the study examined the tri-reference-point hypothesis by analyzing airport ground access mode choice behaviors with a pooled framework that combined revealed and stated preferences. Moreover, the study developed four alternative specifications for schedule delay variables, assuming that air passengers used different reference points to determine relative gains and losses of the expected airport arrival time. The specifications included selecting both EAT and LAT as the zero-utility points (an indifference-band specification) and either one of PAT, EAT, and LAT as the single zero-utility point. Regardless of which specification was employed for schedule delay variables, the tri-reference-point hypothesis was generally supported. In particular, a significant difference of the rate of change of utility around PAT, EAT, and LAT was identified in the analysis results. When managing increasing road travel times and increasingly congested terminals, air passengers were more willing to retime their origin departure time to an earlier time than to switch their ground access mode. The implications of the analysis results for airport ground access management are discussed in the study.

机场地面访问行为的三参考点假设开发

研究应用了单参考点或安全边际假设来检验先进的旅行者信息如何影响旅行行为。然而,这些理论可能无法在机场地面准入行为方面完全捕捉始发地出发时间、机场准入时间和航站楼处理时间之间的权衡。在这项研究中,我们开发了一个三参考点假设,并假设效用的变化率可能会在航空旅客首选 (PAT)、最早可接受 (EAT) 和最晚可接受 (LAT) 机场到达时间发生变化。该研究利用从台北松山机场 304 名乘客收集的经验数据集,通过使用结合了揭示和陈述偏好的汇总框架分析机场地面访问模式选择行为,检验了三参考点假设。而且,该研究为航班延误变量制定了四种替代规范,假设航空乘客使用不同的参考点来确定预期机场到达时间的相对收益和损失。规范包括选择 EAT 和 LAT 作为零效用点(无差异带规范)以及 PAT、EAT 和 LAT 之一作为单个零效用点。无论采用哪种规范用于进度延迟变量,一般都支持三参考点假设。特别是,分析结果中确定了围绕 PAT、EAT 和 LAT 的效用变化率的显着差异。在管理越来越多的道路旅行时间和越来越拥挤的终端时,航空旅客更愿意将他们的出发时间重新安排到更早的时间,而不是转换他们的地面访问模式。研究中讨论了分析结果对机场地面准入管理的影响。
