Singapore is affected by transboundary haze events, where adverse health effects from particulate pollutants exposure instigate individuals to take protective measures. Transport policymakers are concerned how individuals might change their commuting behaviours to reduce outdoor air exposure— specifically, switching from “open” transport modes (walking, etc.) where commuters may be required to wait for transit or travel the last mile outdoors, to “closed” transport modes (point-to-point private transport). Such trends make efforts to reduce reliance on private transport more challenging. We assess the effect that knowledge of an impending haze event has on parents' transport mode decisions for their primary school child's school commute. We exploit a randomized experiment embedded within a survey to tease out the incremental effect of varying transboundary haze severity (Band 2: Elevated, Band 3: High, Band 4: Very High) on parents' preference to send their child to school via “closed” transport modes. We find that while haze increases parents' motivation to switch to “closed” modes of transportation, the effect is not linear. Our findings have implications for transport mode utilization beyond haze to all aspects of environmental harms, as households grow increasingly aware and concerned about the interaction of transportation and health outcomes.

新加坡受到跨界雾霾事件的影响，接触颗粒污染物对健康产生不利影响，促使个人采取保护措施。交通政策制定者关注的是个人如何改变他们的通勤行为以减少室外空气暴露——具体来说，从“开放式”交通模式（步行等）转变为“封闭式”交通模式（点对点私人交通），因为通勤者可能需要等待过境或在户外走最后一英里。这种趋势使减少对私人交通的依赖的努力更具挑战性。我们评估了即将到来的雾霾事件对家长为小学生上学通勤选择交通方式的影响。我们利用一项调查中的随机实验，梳理出不同跨境雾霾严重程度（2级：高，3级：高，4级：非常高）对家长选择“封闭”交通方式送孩子上学的增量影响。我们发现，虽然雾霾增加了家长转向“封闭”交通方式的动机，但这种效果不是线性的。随着家庭越来越意识到并关注交通与健康结果的相互作用，我们的研究结果对除雾霾之外的交通方式利用以及环境危害的各个方面都有影响。

In Santiago, the capital of Chile, an ambitious reform of the public transport system, named Transantiago, was introduced in February 2007. Serious design and implementation problems were immediately evident, creating a major social and political crisis. In this paper we revisit this experience and argue that one of the main ―if not the main― design errors behind the initial failure was the lack of funding for infrastructure and operational subsidies. The higher cost of the new system was implicitly funded through a decrease in the fleet size and network coverage, as well as an excessive trunk-feeder service configuration. This ultimately led to an increase in the generalized cost of transit and a significant reduction in users’ welfare. We argue that this same issue is apparent in other problematic transit reforms in the region, including Mibus in Panama, SITP in Bogota and the SITM experience in intermediate cities of Colombia. The main lesson for policymakers is that if public funds are not available then the pace and ambitions of a transit reform need to be scaled back.

2007年2月，智利首都圣地亚哥推出了一项雄心勃勃的公共交通系统改革，名为Transantiago。严重的设计和执行问题立即显现出来，造成了重大的社会和政治危机。在本文中，我们重新审视了这一经验，并认为最初失败背后的主要（如果不是主要的话）设计错误之一是缺乏基础设施和运营补贴的资金。新系统的高成本是通过机队规模和网络覆盖范围的减少以及过度的干线服务配置来隐性资助的。这最终导致了总体运输成本的增加和用户福利的显著减少。我们认为，同样的问题在该地区其他有问题的交通改革中也很明显，包括巴拿马的Mibus、波哥大的SITP和哥伦比亚中间城市的SITM经验。给政策制定者的主要教训是，如果没有公共资金，那么交通改革的步伐和雄心就需要放慢。

This conceptual paper is about the performance effects of incentivized transit systems also providing wage rate incentives to employees to increase their skills-aided efforts to improve performance. It derives conceptual models, imposes them on transit systems, and using their data estimates a wage, cost and share equations as a system. It finds beneficial effects of these incentives and divides the cost change from employee effort into the effects of skills, effort itself, and economies of scale. It finds effort's cost increasing effect moderated by the effects of economies of scale and skills and a nonlinear (inverted U-shaped) relationship between wages and effort from which two groups of transit systems are identified. In the majority group, employees can be given incentives in the form of small wage premiums to increase their effort to improve transit system performance. And in the other, employees hold back performance improvement efforts to maintain their current high wages. Finally, the study divides the cost effect of directly provided service into the substitution effect and the lump-sum effect and finds the latter's effect large and negative and more than compensates for the cost increasing effect of input substitution from the lower wages.

这篇概念性论文是关于激励性交通系统的绩效影响，也为员工提供工资率激励，以提高他们的技能，帮助提高绩效。它推导出概念模型，将其应用于交通系统，并使用它们的数据作为一个系统来估计工资、成本和共享方程。它发现了这些激励的有益影响，并将员工努力的成本变化分为技能、努力本身和规模经济的影响。它发现，努力的成本增加效应受到规模经济和技能经济的影响以及工资和努力之间的非线性（倒u形）关系的调节，由此确定了两组交通系统。在大多数群体中，员工可以以小额工资溢价的形式获得激励，以增加他们改善交通系统性能的努力。在另一种情况下，员工为了维持目前的高工资而抑制绩效改善的努力。最后，研究将直接提供服务的成本效应分为替代效应和一次性支付效应，发现一次性支付效应较大且为负，足以弥补低工资投入替代带来的成本增加效应。

The prolonged transition period towards autonomous vehicles necessitates dedicated infrastructure to maximize operational safety and efficiency. This study proposes an innovative underground rapid shared autonomous vehicle (SAV) service designed for dense urban environments with limited surface capacity. Recognizing the importance of user acceptance in adopting emerging mobility technologies, the research employs psychographic segmentation and discrete choice modeling derived from a comprehensive stated preference survey involving 882 respondents in Seoul, Korea. Respondents were segmented into three psychographic segments: Time-Sensitive AV Adopters (TSAA), Time-Sensitive AV Hesitators (TSAH), and Cost-Conscious Traditional Actives (CCTA). The market-segmented multinomial logit models for each segment revealed that TSAA respondents demonstrated the highest propensity for SAV adoption, driven by their high valuation of travel time savings and strong acceptance of autonomous technology. Conversely, TSAH displayed cautious optimism toward AV adoption, necessitating assurances regarding service reliability and comfort. CCTA respondents, characterized by strong cost-sensitivity and conservative transportation preferences, exhibited the lowest willingness to adopt SAV. The study highlights the effectiveness of psychographic market segmentation in explaining mode choice behaviors toward SAV. This approach can effectively facilitate the broader acceptance of automated mobility services in densely populated metropolitan areas.

向自动驾驶汽车过渡的漫长过程需要专门的基础设施，以最大限度地提高运营安全性和效率。本研究提出了一种创新的地下快速共享自动驾驶汽车（SAV）服务，该服务专为地表容量有限的密集城市环境而设计。认识到用户接受度在采用新兴移动技术方面的重要性，该研究采用了心理细分和离散选择模型，这些模型来自韩国首尔的一项涉及882名受访者的综合陈述偏好调查。受访者被分为三个心理类型：时间敏感型自动驾驶采纳者（TSAA）、时间敏感型自动驾驶犹豫者（TSAH）和成本意识传统活动者（CCTA）。每个细分市场的多项式逻辑模型显示，TSAA受访者表现出最高的SAV采用倾向，这是由于他们对节省旅行时间的高度评价和对自动驾驶技术的强烈接受。相反，TSAH对自动驾驶的采用持谨慎乐观态度，认为必须保证服务的可靠性和舒适性。CCTA受访者成本敏感性强，交通偏好保守，采用SAV的意愿最低。该研究强调了心理市场细分在解释SAV模式选择行为方面的有效性。这种方法可以有效地促进在人口密集的大都市地区更广泛地接受自动化移动服务。

This article explores the use of smartphone applications in motorcycle (MC) taxi operation in the Philippines. Adopting the informal-formal dichotomy, and using a qualitative approach, the paper: (1) reviews the development of MC taxis from the livelihood, service, and institutional viewpoints; and (2) explores the evolving forms of MC taxi regulation, including the role of technology, competition, ownership, and agreements. The article confirms the Philippine's long history with motorcycles. It reinforces the role of motorcycles in filling the public transport gap. Ideally, a good public transport system meets the “formal” service standards. However, the policy response has persistently been reactive. Transport network companies used technology to advocate for drivers' livelihoods and legitimize their operations. Unfortunately, this is also symptomatic of the bigger issue that needs to be tackled, the need for a modern or formal urban public transport system that meets commuters' service quality expectations. These expectations include comfort, access, reliability, and environment-friendliness, as well as fair income and benefits for the MC drivers. While app-based technology can improve mobility management, it should also be consistent with the national policy and service quality expectations of commuters and contribute towards more secure livelihoods or income needs of drivers.

本文探讨了智能手机应用程序在菲律宾摩托车（MC）出租车运营中的使用。本文采用非正式-正式二分法，采用定性分析方法，从民生、服务和制度三个角度回顾了MC出租车的发展历程；(2)探讨了MC出租车监管的演变形式，包括技术、竞争、所有权和协议的作用。这篇文章证实了菲律宾摩托车的悠久历史。它加强了摩托车在填补公共交通空白方面的作用。理想情况下，良好的公共交通系统符合“正式”的服务标准。然而，政策回应一直是被动的。交通网络公司利用技术来维护司机的生计，并使他们的运营合法化。不幸的是，这也预示着一个更大的问题需要解决，即需要一个现代化或正式的城市公共交通系统来满足通勤者对服务质量的期望。这些期望包括舒适性、可及性、可靠性、环保性，以及对MC驾驶员公平的收入和福利。虽然基于应用程序的技术可以改善交通管理，但它也应该符合国家政策和通勤者对服务质量的期望，并有助于司机更安全的生计或收入需求。

This paper evaluates the role of transportation infrastructure policies in raising productivity by considering heterogeneities in efficiency, redistribution, and equity. Using a three-step instrumental variable identification strategy, we estimate the causal impacts of road investments on GDP per capita in Brazilian municipalities during the Growth Acceleration Program (PAC), implemented from 2007 to 2018. Our findings show that highway investments significantly increased productivity, particularly in less-developed and poorly connected municipalities. Conversely, returns were lower or insignificant in highly developed and efficient areas, likely due to infrastructure saturation and implementation inefficiencies. These results suggest that road impacts are not homogeneous and that spatial targeting matters. Building on these heterogeneities, we calculate regionalized return rates and identify “focal points” where road investments can achieve both economic efficiency and inclusion objectives. We find that Brazil could have achieved higher overall returns by prioritizing redistributive and spatially equitable investments rather than concentrating resources in already-developed regions. The paper contributes to the literature by jointly analyzing the efficiency, redistribution, and equity dimensions of infrastructure investment and providing policy-relevant evidence on how to improve the design and targeting of national transport programs.

本文通过考虑效率、再分配和公平方面的异质性，评估了交通基础设施政策在提高生产率方面的作用。采用三步工具变量识别策略，我们估算了2007年至2018年实施增长加速计划（PAC）期间，道路投资对巴西各城市人均GDP的因果影响。我们的研究结果表明，高速公路投资显著提高了生产率，尤其是在欠发达和交通不发达的城市。相反，在高度发达和高效的地区，回报较低或微不足道，可能是由于基础设施饱和和执行效率低下。这些结果表明，道路影响不是均匀的，空间定位很重要。基于这些异质性，我们计算了区域回报率，并确定了道路投资既能实现经济效率又能实现包容性目标的“焦点”。我们发现，巴西本可以通过优先考虑再分配和空间公平的投资，而不是将资源集中在已经发达的地区，实现更高的总体回报。本文通过共同分析基础设施投资的效率、再分配和公平维度，并就如何改进国家交通规划的设计和目标提供与政策相关的证据，为文献做出了贡献。

Public-private partnership (PPP) is expanding in the Gulf Cooperation Council (GCC) nations. In all GCC countries, there are several transport initiatives, predominantly, pertaining to railways, with substantial projected investments. This paper analyses the PPP sector concerning railway and transport initiatives in the GCC region. It presents findings of an online survey conducted in 2022, among industry leaders and subject matter experts in the GCC countries. The survey aimed to assess current PPP practices in GCC countries, examine its development, and evaluate its alignment with established success criteria. The results show an upward trend in the endorsement and promotion of PPP. The findings indicate that industry specialists in the GCC understand elements essential for the success of PPP ventures. The observed variation and breadth of responses among survey participants substantiate the market's relatively nascent and challenging condition. The survey results also show that the GCC countries often score lower than the other OECD high-income countries and need improvements in almost all PPP delivery phases and thematic areas. It is therefore argued that PPP in the GCC nations is a unique and novel endeavour. The findings provide insights into critical reforms to enhance its appeal to international private investors.

公私伙伴关系（PPP）在海湾合作委员会（GCC）成员国不断扩大。在所有海湾合作委员会国家中，有几项运输倡议，主要与铁路有关，预计有大量投资。本文分析了海湾合作委员会地区有关铁路和运输计划的PPP部门。它介绍了2022年在海湾合作委员会国家的行业领导者和主题专家中进行的一项在线调查的结果。该调查旨在评估海湾合作委员会国家目前的PPP实践，检查其发展情况，并评估其与既定成功标准的一致性。结果显示，对PPP的认可和推广呈上升趋势。调查结果表明，海湾合作委员会的行业专家了解PPP企业成功的关键因素。在调查参与者中观察到的变化和反应的广度证实了市场的相对新生和具有挑战性的条件。调查结果还显示，海湾合作委员会国家的得分往往低于其他经合组织高收入国家，几乎在所有PPP交付阶段和专题领域都需要改进。因此，有人认为海湾合作委员会国家的PPP是一项独特而新颖的努力。调查结果为加强对国际私人投资者的吸引力的关键改革提供了见解。

A cost model for road public transport sensitive to the operating program 基于运营计划的道路公共交通成本模型

Pub Date : 2025-11-19 DOI: 10.1016/j.retrec.2025.101670

Most models for estimating the cost per kilometer of local public transport (LPT) do not include variables attributable to the service operating program (SOP), that is the document showing lines, routes, stops, rides and related timetables. Therefore, by these tools it is not possible to take into account the impact, on the unit cost, of the different use of drivers and vehicles resulting from the number and time of the rides performed. This work, to overcome this important limitation proposes a modification, applicable to most existing models already including the other variables that most affect the cost. In particular, a statistical relationship has been built as a function of the descriptive variables of the SOP known to all, capable of providing a factor K that, multiplied by the value of the cost derived from any model, allows it to be corrected as a result of the specific characteristics of the SOP. The methodology developed is of general validity. The model built for the calculation of K has been calibrated on a regional LPT service offered in an area with weak demand.

大多数估算当地公共交通（LPT）每公里成本的模型都不包括可归因于服务运营计划（SOP）的变量，即显示线路、路线、站点、乘车和相关时间表的文件。因此，通过这些工具，不可能考虑到不同的司机和车辆的使用对单位成本的影响，这些影响是由乘坐次数和时间造成的。为了克服这个重要的限制，这项工作提出了一种修改，适用于大多数已经存在的模型，包括最影响成本的其他变量。特别是，我们建立了一个统计关系，作为大家都知道的SOP的描述性变量的函数，能够提供一个因子K，乘以从任何模型得出的成本值，允许它作为SOP的特定特征的结果进行修正。所开发的方法具有普遍的有效性。为计算K而建立的模型已在需求较弱的地区提供的区域性LPT服务上进行了校准。具体的重新校准将允许在运输需求和供应的规模、类型和特征不同的领域使用它。

The COVID-19 pandemic has triggered pronounced fluctuations in the shipping market, complicating decisions on freight rate setting, capacity allocation, and investment planning. Understanding how inflation influences container shipping is therefore essential for shipping companies seeking to anticipate market changes more accurately. This study examines the nonlinear relationship between container freight rates and inflation, focusing on the China–Europe route and the China–North America West Coast route. To ensure robust results, the analysis incorporates three control variables: port congestion index, container trade index, and container fleet growth. The findings reveal an inverted N-shaped relationship between inflation and freight rates, with two inflection points demarcating shifts in the direction of the effect: inflation exerts a positive influence within the range between the two points but a negative influence outside it. The inflection points observed in this study are higher for the United States compared to Europe, likely due to differences in economic performance and monetary policy. These results highlight the need for shipping companies to adapt their operational and pricing strategies based on the specific economic conditions of the regions in which they operate.

新冠肺炎疫情引发航运市场剧烈波动，使运价设定、运力分配和投资规划等决策复杂化。因此，了解通货膨胀如何影响集装箱运输对于寻求更准确地预测市场变化的航运公司至关重要。本文以中国-欧洲航线和中国-北美西海岸航线为研究对象，探讨了集装箱运价与通货膨胀之间的非线性关系。为了确保稳健的结果，分析纳入了三个控制变量：港口拥堵指数、集装箱贸易指数和集装箱船队增长。研究结果揭示了通货膨胀和运费之间的倒n型关系，两个拐点划分了影响方向的变化：通货膨胀在两个拐点之间的范围内产生积极影响，但在这两个拐点之外产生消极影响。本研究中观察到的美国的拐点高于欧洲，可能是由于经济表现和货币政策的差异。这些结果突出表明，航运公司需要根据其经营所在地区的具体经济条件调整其业务和定价战略。

Variations in value of travel time savings on express lanes: Evidence from passively collected data 快速通道上节省的旅行时间价值的变化：来自被动收集数据的证据

This paper investigates preference heterogeneity in the Value of Travel Time Savings (VTTS) among Express Lane (EL) users, highlighting how VTTS varies across individuals. The study contributes to the literature by demonstrating how travel demand modeling can be effectively conducted using a large, high-resolution dataset that integrates transponder-based Express Lane usage with travel time savings derived from probe vehicle data. VTTS is estimated through a trip generation model, where the dependent variable is trip frequency.

To address the absence of user-specific socio-demographic characteristics and to capture the full spectrum of preference heterogeneity, the study employs three advanced ordered logit models: the generalized ordered logit (GOL), the heteroskedastic ordered logit (HOL), and the latent class ordered logit (LCOL). Results reveal substantial heterogeneity in user preferences. Notably, infrequent Express Lane users demonstrate a higher willingness to pay for time savings compared to regular commuters, suggesting that EL usage patterns reflect deeper differences in value perception.

By identifying nuanced user segments and their evolving preferences, this study offers actionable insights for transportation agencies, planners, toll operators, and policymakers. The findings support the development of dynamic tolling and incentive-based strategies that are responsive to user diversity.

本文研究了快速通道（EL）用户出行时间节省价值的偏好异质性，重点分析了不同个体之间的差异。该研究通过展示如何使用大型高分辨率数据集有效地进行旅行需求建模，从而为文献做出了贡献，该数据集将基于应答器的快速车道使用情况与探测车辆数据节省的旅行时间相结合。通过一个行程生成模型来估计VTTS，该模型的因变量为行程频率。为了解决用户特定社会人口特征的缺失问题，并捕捉偏好异质性的全部范围，本研究采用了三种先进的有序logit模型：广义有序logit （GOL）、异方差有序logit （HOL）和潜在类别有序logit （LCOL）。结果揭示了用户偏好的实质性异质性。值得注意的是，与经常通勤的人相比，不经常使用快速通道的用户表现出更高的为节省时间而付费的意愿，这表明，快速通道的使用模式反映了价值感知的更深层次差异。通过识别细微差别的用户群体及其不断变化的偏好，本研究为交通运输机构、规划者、收费运营商和政策制定者提供了可操作的见解。研究结果支持根据用户多样性制定动态收费和基于奖励的战略。
