Abstract :
In the ride-hailing market, the platforms could recruit contractors subject to prescriptive schedules to reduce the labor supply uncertainty and balance the demand and supply, and the drivers are entitled to become a freelancer or a contractor and choose the schedule they would like to provide the service. This paper proposes an analytical framework to capture the drivers ' decisions of becoming a freelancer and contractor as well as how to arrange their work schedules in a dual sourcing market. The utility structures for two kinds of drivers, freelancers and contractors, are defined and a time-expanded network is adopted to portray the drivers ' work schedule choices. With this setting, the drivers ' simultaneous contractual mode and work schedule selection model is formulated and the algorithm is designed. The numerical examples are conducted to investigate the characteristics of the equilibrium solutions. The results show that a dual-sourcing market is always advantageous to contractors and conditionally beneficial to the platform, freelancers and customers. When there is low potential demand, higher fixed salary is preferred for the platform to attract contractor and complement the labor supply. When the market is thriving, the effect of the profits ' increment by dual-sourcing is not obvious. This work could provide new insights on how to manage a dual-sourcing market for the platform.

Abstract :
This study explores how two typical pedagogical modes, namely, problem-based and employment-based pedagogical mode, contribute to the employability of university and college students. Based on analysis of a total sample of 428 undergraduates from Chinese universities and colleges using structural equation modelling, the results show that students' absorptive capacity was positively related to their employability. The employment-based pedagogical mode, considering the absorptive capacity as a partial mediator, was positively related to students' employability. The problem-based pedagogical mode, considering the absorptive capacity as a complete mediator, was positively related to students' employability. Absorptive capacity act as an important mediator variable when the employment-based and problem-based pedagogical mode influence students' employability. Based on the findings, specific suggestions and managerial implications for higher education policy, manpower training, and future research are provided.

Abstract :
考虑自动驾驶背景下新型多模式通勤方式并存的情景,设置存在自动驾驶汽车专用道,即传统汽车与自动驾驶汽车分离出行的双车道交通系统,基于瓶颈模型进行建模,分析实施可交易电子路票与鼓励合乘组合管理策略前后对路票市场价格、通勤者出行方式选择和自动驾驶汽车内生渗透率的影响,并以系统总成本改善效果最佳为目标,协同优化组合管理策略参数。研究表明:实施组合管理策略后,路票市场价格可唯一确定;部分独驾通勤者转向合乘出行,系统总车辆数减少,两车道的早高峰持续时间均缩短,交通拥堵得到改善;存在满足特定关系的组合管理策略参数使得系统总成本改善最佳,且能够得到系统最优时的私人自动驾驶汽车和共享自动驾驶汽车的市场渗透率。研究可为未来城市交通管理提供新的思路。

Abstract :
Public support is crucial for the successful implementation of congestion charging schemes. The Tradable Credits Scheme (TCS), a novel concept built upon the cap-and-trade principle, is believed to possess qualities of effectiveness and fairness that should lead to greater public approval. This study investigates the level of acceptance of TCS among the public and its impact on the propensity to shift travel modes in the TCS framework. In this study, we used the Theory of Planned Behavior, encompassing components such as attitudes toward TCS, subjective norms and perceived behavioral control and assessed the perceived effectiveness and equity of TCS. Data were acquired through an online survey involving 544 participants in China. The findings indicate that public acceptance of TCS is significantly influenced by subjective norms and attitudes toward TCS. In turn, behavioral intention is indirectly shaped by these factors, with acceptance serving as a mediator. Perceived behavioral control exerts a direct influence on behavioral intention, while perceived effectiveness and equity positively impact both the acceptance of TCS and behavioral intention. Moreover, latent profile analysis was used to determine the influence of various factors on TCS acceptance, following which we categorized the participants into four distinct groups. The results show that age, city scale, income, holding a driving license or not, car ownership, necessity through congested areas, main transportation modes, and the frequency of using different travel modes all affect the distribution of individuals in support or rejection groups Notably, over one-third of participants express TCS acceptance, with most holding a neutral stance, indicative of TCS's potential for public acceptance with effective guidance and comprehensive explanation. In summary, this research provides novel insights into the multifaceted factors that influence individuals' acceptance of TCS and offers valuable assistance in promoting an innovative traffic demand management policy. © 2024 Elsevier Ltd

Abstract :
通过实施差异化激励绿色出行策略,可以合理引导通勤者转向指定出行方式,并有效缓解城市道路拥堵现象.针对允许独自驾驶、多人合乘与公交出行共存的多模式单起讫点交通系统,本文将激励对象范围与数额差异纳入考虑,以瓶颈模型为基础,对鼓励绿色出行的差异化激励策略进行分析研究.此外,对存在两个服务商提供有偿合乘出行服务以及不同激励预算设置情形下的策略实施效果也进行了分析.研究结果表明,差异化激励绿色出行策略可通过不同的差异系数与激励数额设置实现管控目标;当最小化带有减排约束的出行成本时,可供设置的激励数额与差异系数取值范围缩小,且随固定预算值的变小而缩短;此外,结合动态拥挤收费策略,可实现无预算投入下消除道路拥挤排队,并调整出行需求时空分布.

Abstract :
The advent of autonomous vehicles (AVs) with self-parking capability puts forward new requirements for parking policy and management. In a transportation system with both general and dedicated AV lanes, this work aims to examine and compare the effectiveness of different parking policies on the morning commute. To be specific, three policies of parking space allocation, namely, first-come-first-service (FCFS), advanced reservation (AR), and their combination (CB), are proposed to guide the commuters’ travel choices. Commuters can drive regular vehicles (RVs) alone on the general lane or ridesharing shared autonomous vehicles (SAVs) on the dedicated AV lane. The occurrence conditions and the resultant SAV penetration rates for various scenarios under three parking policies are revealed. The area division for various scenarios with respect to two key parameters is presented, and the typical departure patterns are plotted as well. The numerical results clarify that the CB policy always has a better effect on the total travel cost than FCFS and AR policies. The optimal CB policy is quantified in terms of the optimal amount of all parking spaces and the proportion of unreserved parking spaces. These findings help to improve the spatial and temporal distribution of traffic flow and allocate transportation resources efficiently in the coming era of autonomous driving. © 2024 Elsevier Ltd

Abstract :
This study explores how individuals respond to the Tradable Credits Scheme (TCS), a cap-and-trade approach aiming to reduce congestion, by introducing the norm activation model (NAM). The research utilized questionnaire data from 544 Chinese participants. First, we analyzed the credit proportion thresholds for shifting travel mode and the distribution of participants corresponding to five thresholds. Second, we developed the latent and explicit variable model, revealing that NAM could explain acceptability of TCS, with personal norms being crucial; specifically, personal norms could positively predict perceived effectiveness, attitude towards TCS, and behavior intention. Finally, we performed a moderated-mediation analysis, for which the findings suggested TCS's potential in promoting sustainable travel, with driving licenses and the frequency of weekly trips as significant behavior moderators. People with driving licenses and having less travels per week would be more likely to intensify their behavior intention by enhancing their recognition on TCS. This work contributes to understanding TCS as an innovative congestion policy and its influence on sustainable travel behaviors. © 2024 Elsevier Ltd

Abstract :
如何调动合适数量的司机在合适的时间为乘客提供服务是网约车运营的核心.考虑司机行为特征的异质性,本文以时间拓展网络为基础,假设司机效用由消费效用和参考效用组成,构建可兼容两大行为理论的统一框架来刻画司机的上下班劳动供给行为,并提出相应的均衡求解算法,分析不同行为理论驱使和偏好不同工作时长的司机在均衡市场中的上下班时间选择.在此基础上提出抽成式和任务式两类激励方式,建立相应模型,研究具有不同行为特征的司机对不同激励方式的反应,并探索平台的最优激励策略.研究结果表明,受新古典主义行为驱动的司机对激励的反应高于目标收入行为驱动的司机,任务式激励对偏好工作时间长的全职司机激励效应较高,兼职司机偏好抽成式与任务阈值低的激励方式.本文为平台理解司机劳动供给行为,进一步管理和激励运力提供理论参考和现实依据.

Abstract :
从活动的视角研究无人驾驶带来的通勤行为变化.将车内边际活动效用和车内时间利用效率纳入考虑,构建无人驾驶汽车通勤者基于活动的效用函数.对常数与线性边际活动效用情形下的出发与停车模式、最优动态瓶颈收费,以及模型性质进行推导,并与基于出行的模型结果进行比较.结果表明常数边际活动效用情形时,早到出发率是车内边际活动效用和车内时间利用效率的增函数,晚到出发率则反之;线性边际活动效用情形下,早到人数与车内时间损耗程度无关,与上班时间正相关.实施最优瓶颈收费后发现,基于出行的模型会高估总收费收入的上界,低估总收费收入的下界.从实现系统净效用最大化的角度来说,应结合停车社会成本函数和具体情境调整停车密度设置.

Abstract :
计划延误成本的设定对早高峰通勤行为的分析有着至关重要的作用.文章基于时变计划延误成本假设,考虑普通驾驶和共享无人驾驶两种出行方式,构建早高峰通勤模型,研究时变计划延误成本假设对早高峰通勤行为的影响.与常数延误成本假设不同,时变计划延误成本假设通勤者的单位延误成本是随时间变化的.研究结果表明,时变计划延误成本假设下通勤者出发率和最优收费均为非线性曲线;与基于时变计划延误成本假设的模型相比,常计划延误成本假设的模型总是高估共享无人驾驶内生市场渗透率、系统总成本和对共享无人驾驶汽车的最优收费,低估早高峰持续时长和对传统汽车的最优收费.因此,考虑计划延误成本的时变效应有助于交通管理部门制定更加精确的配套政策.
