低碳政策下考虑行程时间不确定性的机场地面通达方式选择
Choice of Airport Ground Access Mode Considering Travel Time Uncertainty under Low-Carbon Policies
摘要
Abstract
In the context of rapid growth in air passenger volume,in order to more effectively guide travelers to choose low-carbon and environment-friendly airport ground access modes,taking Xi'an Xianyang International Airport as an example,this study investigated the effects of low-carbon con-sumption voucher subsidies and residents'environmental awareness on airport ground access method selection preferences,and explored the role of travel time uncertainty in guiding residents towards choosing sustainable mobility modes.Considering the complexity of traffic environments,a declara-tive choice preference experiment was designed to investigate travelers heading to the airport,taking into account the uncertainty of travel time.Based on the collected data,this study developed a hybrid Cumulative Prospect Theory-Multinomial Logit(CPT-MNL)model to analyze travelers'preferences under different scenarios.The estimated results reveal that,on the one hand,factors such as the num-ber of carry-on luggage,travel time uncertainty,travel costs,and preferences for arriving early at the airport significantly influence the choice of airport ground access modes.On the other hand,the pro-portion of carbon emissions reduction and consumption voucher subsidies have significant impact on sustainable mobility modes.This underscores that amid the current context of promoting green travel,travelers are increasingly valuing carbon emissions reduction and consciously opting for sustainable mobility modes.The low-carbon consumption voucher could further encourage travelers to shift from private transport to public transport.Thus,transportation managers,when advocating for public transit use,can emphasize environmental considerations and offer policy incentives.Given the significant im-pact of travel time uncertainty on mode choice,results show that enhancing the reliability of public transport operations to reduce travel time delays can further facilitate the shift towards low-carbon pub-lic transit,contributing to traffic structure adjustments.Therefore,it is essential to continually reinforce low-carbon travel concepts,cultivate a low-carbon societal atmosphere,enhance the convenience and reliability of public transport,focus on the characteristics of travelers'low-carbon travel choices,and implement low-carbon incentive strategies for encouraging the use of sustainable mobility modes.关键词
