Unfortunately, significantly large proportions of rural populations worldwide, particularly in relatively lower-income countries, still lack access to all-weather roads. I leverage data from the first phase of India's Pradhan Mantri Gram Sadak Yojana (PMGSY) – the Prime Minister's Village Road Scheme – to analyze whether the provision of basic single-lane all-weather road links to previously unconnected rural habitations has led to growth in economic performance, specifically in the agriculture sector. I empirically investigate whether, all else equal, districts that made greater progress in rural road connectivity – in terms of km of new road constructed and the number of new habitations connected, relative to targets – over the first decade of the PMGSY experienced greater levels of growth in per capita GDP, overall and in the agriculture sector. Results show that new rural road development can indeed have a significant positive impact on per capita agriculture GDP growth; places with relatively lower baseline agricultural performance can benefit more. A series of OLS, Spatial Error, and 3SLS models confirm the reliability of estimated effects. In addition to demonstrating the positive economic impact of the PMGSY in India, specifically its contribution to growth in economic performance and productivity in the agriculture sector, this study underscores the economic rationale of rural road connectivity investments across the developing world.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 305-318"},"PeriodicalIF":6.3,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a critical and promising mode of public passenger transportation, ensuring the sustainable development of HSR in China necessitates a significant focus on improving passenger satisfaction. This paper presents a systematic framework from the perspective of Product-Service System (PSS) configuration, encompassing key components such as the identification and prioritization of critical passenger requirements, the prioritization of service quality improvement measures, and the optimal allocation of limited resource. Specifically, the framework involves the following steps: Firstly, text mining of social media online-reviews is utilized for the identification of key passenger requirements. Secondly, an improved Best-Worst Method under basic uncertain linguistic information environments (BULI-BWM) is employed to determine the importance of these requirements. Thirdly, an extended Quality Function Deployment (QFD) under uncertain information environments is applied to derive and prioritize service quality improvement measures. Finally, a nonlinear goal optimization model is proposed to optimize resource allocation with the aim of maximizing the level of passenger satisfaction improvement. This research, driven by a fusion of social media data, expert knowledge and experience, reveals six key passenger requirements, with current passenger concerns focusing on reliable train operations, ticket price &amp; availability, and riding convenience. Furtherly, six targeted service improvement measures are proposed, along with optimal resource configurations to achieve the maximum improvement of passenger satisfaction levels. The findings provide practical suggestions and effective support for operational decision-making by HSR service operators and designers.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 244-262"},"PeriodicalIF":6.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strategic interactions between electric vehicle manufacturers and mobility service providers","authors":"Yanyan Ding ,&nbsp;Sisi Jian","doi":"10.1016/j.tranpol.2025.04.004","DOIUrl":"10.1016/j.tranpol.2025.04.004","url":null,"abstract":"<div><div>We study a vehicle manufacturer encroachment and multichannel distribution problem in which a vehicle manufacturer (VM) decides whether and how to enter the mobility service market in anticipation of its primary buyer’s responses, i.e., the existing mobility service operator (MSP). Before the VM enters, the relationship between the VM and MSP is between sellers and buyers. However, if the VM enters, their mutual relationship will be complicated. First, since the MSP is better informed than the VM about rider demand information, the VM needs to infer the true mobility service market size from the order quantity requested by the MSP, which results in a “<em>signaling game</em>”. Second, the VM entry might benefit or hurt the MSP, i.e., they might be substitutes or complements. Third, the VM’s entry decision influences the vehicle price. This further affects the surplus of individual buyers in the vehicle sales market and travelers in the mobility service market. In light of this, we develop a dynamic Bayesian game model to characterize the decision process of the VM and MSP. Analytical results show that when VM and MSP are “<em>substitutes</em>” from the perspective of end users, VM’s entry will induce the MSP to decrease its order quantity when the market size is small while maintaining the same level as in the full information setting when the market size is large. This is opposite to the outcome when they are “<em>complements</em>”. Moreover, the seesaw effect between the two markets normally raises MSP’s profit while reducing VM’s profit. Numerical results demonstrate that the VM can strategically determine the optimal vehicle price to induce MSP to distort the order quantity in favor of its benefits. We find that as the size of the vehicle sales market increases, the VM will be better off adopting the multichannel strategy but will allocate fewer vehicles to the mobility service market. The MSP is worse off when they are substitutes while better off when they are complements. We also find that the VM entry benefits travelers since they have additional options and the mobility service prices are lower than when the VM does not enter.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 288-304"},"PeriodicalIF":6.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143874613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing an empirical dataset of 51,454 <span>UAD</span> offenders in Taiwan over an eight-year period (2014–2021), the analysis results support the hypothesis that greater accessibility to the bus transit network significantly decreases the likelihood of recidivism among naïve offenders, particularly among older adolescents. The findings also reveal that UAD offenders residing in economically disadvantaged neighborhoods are more likely to engage in subsequent offenses compared to those in more prosperous areas, underscoring the importance of enhancing transit services from a social equity perspective. Additionally, consistent with patterns observed in recidivism for other traffic offenses, male offenders and individuals with prior UAD violations are at a higher risk of repeat offenses. These results emphasize the need for targeted interventions within graduated driver licensing programs. This study highlights the significance of early identification and intervention for UAD offenders, particularly through differentiated approaches for naïve and repeat offenders.

The research employs complex network theory to examine spatial and temporal dynamics, integrates multiple central indicators for evaluating node importance, and assesses network robustness under various attack scenarios. Our study demonstrates that China's air cargo network faces challenges such as low route execution rates, an unstable structure, and significant cargo flow imbalances—particularly in low-traffic areas. Strategic hubs, such as Urumqi (URC), Kunming (KMG), Hangzhou (HGH), Shenzhen (SZX), and Nanjing (NKG) play vital roles., while the rise of Ezhou Huahu Airport (EHU) alleviates network pressure on major hubs. Moreover, our analysis reveals a distinct differentiation in hub airport roles, with the network exhibiting scale-free and small-world characteristics. The robustness of the network is shown to vary depending on the type of attack strategy employed, underscoring the need for targeted interventions to enhance overall network efficiency and resilience. Key findings reveal that CACN has a low route execution rate and an unstable structure, with significant cargo flow imbalances, especially in low-traffic regions.

The highway bottleneck capacity is shared between a general-purpose lane for all drivers and a time-limited carpool lane for carpooling vehicles only. Analytical derivations of all possible commute patterns are provided, considering different parking supply levels and capacity allocation strategy. Results show that all bottleneck capacity should be allocated to carpool lane spatially, but the optimal temporal allocation of carpool lane may not be unique for minimizing total trip cost. This implies, the accurate estimation of extra carpool cost to optimize the temporal lane reservation may be no longer necessary for the traffic authority due to the limited parking supply, whilst it is really required when the parking supply is abundant. We also incorporate the traffic authority's social cost budget for both temporal and spatial allocations into the optimization problem, explaining why general-purpose lanes are still prevalent in reality. The research has implications on policy makers as well as workplace parking managers by providing them a framework to design optimized road-space allocation with workplace parking supply.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 157-167"},"PeriodicalIF":6.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
