Tradable credits for managing car travel: a review of empirical research and relevant behavioural approaches

Recently, there has been a surge of interest in Tradable Credits (TC) as an alternative measure to manage the growth of personal car use. This paper summarises the results and methodologies of studies that have sought to anticipate the behavioural responses to several proposed TC schemes that target personal travel. In a critical reflection on this work and in an attempt to inspire future research, we argue that future empirical studies on TC behaviours can greatly benefit from insights from the fields of behavioural economics and cognitive psychology. Therefore, in the second part of the paper, we bring together behavioural concepts from these fields that are relevant in a TC decision-making context. Based on observations from current TC studies and the behavioural mechanisms identified in the second part of the paper, we propose promising directions for future research on understanding the impact of TC on personal car travel.     

Long-term impact of the Shinkansen on rail and air demand: analysis with data from Northeast Japan

This paper analyses how the high-speed rail construction in Northeast Japan (Tohoku) has affected total demand and interregional travel patterns. We use annual interregional passenger data from 1989 to 2012 and apply regression analysis with the demand between Tokyo and the Tohoku prefectures as the dependent variable. We distinguish particularly between the ‘Full-’ and the ‘Mini-’ Shinkansen, where the latter are branch services running with reduced speed. We find that the ‘Full-Shinkansen’ quickly increases rail and total public transport trips and generates additional rail demand year on year. The ‘Mini-Shinkansen’ impacts are less pronounced. Furthermore, our analysis shows that the Shinkansen has shifted some demand from air to rail once it started operation and increased rail share gradually. We therefore suggest that predictions of demand impacts should carefully distinguish immediate from gradual impacts. We also discuss differences in regional demand in that not all prefectures have gained equally from Shinkansen construction.     

Asymmetry in transport fuel demand: Evidence from household level data

Models for gasoline demand for transportation activities generally assume that demand is perfectly reversible with respect to gasoline price (and income). The small literature which relaxes the reversibility assumption in gasoline demand argues technological fixation leads to this asymmetry and utilizes aggregate time-series model to find evidence in favour of asymmetry. In this research it is suggested that there could also be behavioural factors behind this asymmetric response, possibly due to the loss aversion nature of human beings as described in the prospect theory. For the first time, household level data was used to understand asymmetry in gasoline demand in response to changes in gasoline price and income. There was statistical evidence that gasoline price and income both can induce asymmetric changes in gasoline demand among households. Specifically, elasticity with respect to rising prices and falling income is larger than the elasticity with respect to falling prices and rising income respectively, which is consistent with loss aversion in gasoline purchase behaviour. There was also some evidence of heterogeneity in the asymmetric responses between urban and rural households. The results have implications for transport-related energy tax policies or subsidies, while the method can be applied directly for non-energy goods as well.

巴黎公共自行车租赁点规划设计

总结了巴黎公共自行车租赁点规划中采用的出行需求预测方法,规划在分区基础上,根据居住人口、就业岗位、商业和设施4种类型,测算各区日均出行次数,进而确定公共自行车租赁点数量及自行车规模。阐述了租赁点定位的影响因素、定位方法及布设原则。详细分析了租赁点的布设方式,明确路边租赁点、人行道上的租赁点和行道树附近租赁点的布设要点,对自行车、停车桩、服务终端等设施也提出了相关要求。最后,在巴黎经验基础上指出,我国部分城市提出的“解决公交出行最后一公里”的公共自行车系统单一功能定位,不利于租赁点的合理布局;租赁点主要布设在人行道的做法也会引发新的交通问题。

综合考虑托运人面对集卡运输服务和货运代理报价两大顾客选择因素,构建由多个竞争性集卡运营商和一个货运代理商组成的集装箱道路运输市场竞争模型,通过逆向归纳法求解博弈均衡并以上海港进行算例分析.研究发现:若集卡运营商采取提供增值服务策略,则一方面由于承担了增值服务所需成本而导致集卡运营商利润下降;另一方面,集装箱道路运输市场需求的满足程度不断提高,集卡运营商和货运代理商的整体利润也呈现增加趋势.因此,通过对集装箱运输链建立合理的利益分配机制,就能激励集卡运营商主动提供增值服务,从而改变当前集装箱道路运输市场在基本运输服务方面进行恶性价格竞争的局面,实现集卡运营商和集装箱运输链的健康发展.     

考虑动态定价的煤炭调运方案优化研究

煤炭坑口价格的变化与市场供求有重要联系.本文在煤炭坑口价格动态定价的基础上,以煤炭产地和消费地间的煤炭调运量为决策变量,以煤炭流通过程中的总费用最小化为目标,分别构建了煤炭调运系统优化模型和考虑消费者竞争的煤炭调运优化模型,设计了遗传算法和Floyd算法相结合的求解算法.以我国内地煤炭调运问题为案例,分析了价格变化特性、可调出量与消费量比例等因素对煤炭调运方案的影响.结果表明,考虑消费者竞争时煤炭流通广义费用更低;随着煤炭可调出量与消费量比的增加,动态价格较固定价格的煤炭流通广义费用下降更快.

新冠肺炎疫情对民航的影响分析与政策建议

为给政府制定应对策略提供决策支持,基于航班运行数据分析了新型冠状病毒肺炎疫情对民航造成的影响。通过分析2003年“非典”和新型冠状病毒肺炎疫情对民航影响的差异,基于情景假设对2020年民航运输发展形势进行了预测分析,并提出有关政策建议。研究结果表明：新型冠状病毒肺炎疫情对民航市场需求造成了严重的冲击,2020年民航运输形势不容乐观,预计年旅客运输量同比基本持平或下降10.9%。政府部门需在做好疫情防控期间运输保障工作的同时,加快出台积极的产业政策以支撑民航发展。
