However, the effectiveness of these policies and the interplays between them in reducing transportation sectors' carbon emissions in China are still poorly understood. Using a computable general equilibrium model, this study evaluates the effect of renewable electricity deployment and terminal electrification on transportation sectors' carbon emissions in China and reveals their synergy effect. It contributes to the existing literature by revealing how the synergy effect enhances the carbon reduction effects of renewable electricity deployment and terminal electrification in transportation sectors. This study finds that renewable electricity deployment has a double-dividend effect in reducing carbon emissions in transportation sectors and improving their output value, with significant sectoral heterogeneity. Terminal electrification reduces carbon emissions in all transportation sectors, while it causes some damage to their output value. The synergy effect between these policies would enhance the double-dividend effects of reducing transportation sectors’ carbon emissions and benefiting their output value, especially for those with lower electrification rates. Only the synergy effect would mitigate 7.62–42.88 Mt CO₂ of carbon emissions in transportation sectors by 2060, accounting for 1.69–9.53% of total carbon emission under the baseline scenario. We suggest that this synergy effect should be recognized as a key strategy for reducing carbon emissions in the transportation sector.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 135-147"},"PeriodicalIF":6.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601597","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}

Different from the sea waterway, the navigable ship size in an inland river corridor is restricted by the waterway depths in the plentiful and drought periods. This paper deals with the design issue of ship fleet size in an inland river corridor with seasonal change in waterway depth using a vertical structure model. The interactions among consignors, competitive carriers and a public port operator over plentiful and drought periods are considered in the proposed model, together with the impacts of seasonal waterway depth on the ship fleet size. The consignors aim to minimize transport cost by choosing transfer ports in each period. The competitive carriers are intended to maximize their own net profit by determining the shipping freight rates in each period and the ship fleet size (ship frequencies and composition of ship size) over a given time horizon. A public port operator, as an agent of the government, decides the port service charges in each period to maximize social welfare over the given time horizon. The effects of the ratio of drought period duration to plentiful period duration (duration ratio), the ratio of small ship size to big ship size (ship size ratio), and the actual cargo load of big ship in the drought period on the stakeholders and the system are investigated. The results show that: (i) the government always tends to subsidize the carrier at each port in the plentiful period for a large duration ratio, but to subsidize the carrier at its competitive port in the drought period for a small duration ratio and a low cargo load of a big ship at each port; and (ii) a single big (or small) ship type strategy will underestimate (or overestimate) the ship fleet size for a low cargo load of a big ship in the drought period. The method proposed in this paper can serve as a useful tool for the fleet size plan for the carriers and for port regulation for the government so as to achieve a “win-win-win” outcome among consignors, carriers and port operator.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 108-123"},"PeriodicalIF":6.3,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601595","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}

Although emerging economies contribute substantially to the world economy, they struggle to achieve environmental sustainability with increasing industrialization, urban mobility, and transportation. Therefore, this study analyses whether the environmental tax (ET), green technology innovation (GTI), and biofuel use (BF) abate emissions from the transportation sector, considering 11 emerging economies from 2004 to 2022 using the dynamic fixed effect and CS-ARDL estimation techniques. The empirical analysis also discloses the imperative role of institutional quality (IQ) by integrating IQ's direct and moderation effects with GTI, BF, and ET. The empirical evidence highlights that while BF (−0.138), GTI (−0.074), and IQ (−1.303) ameliorate the decarbonization process, ET (−0.123) does not significantly decarbonize the transportation sector in the long-run. Furthermore, the results disclose an important role of IQ in moderating the emissions mitigation effectiveness of GTI (−0.174), BF (−0.129), and ET (−0.193) in emerging economies, indicating that benevolent institutional support is crucial for the sustainable transformation of the transportation sector in the long-run.

Unlike conventional vehicles (CVs), which are restricted to parking in specified lots, AVs eliminate the limitation of human driving and provide travelers with a wider range of parking options. This study examines the distinct parking choice behaviors of AVs and CVs and develops pricing strategies for parking lots. To this end, parking choice models for AVs and CVs are separately developed based on their respective parking costs. An agent-based simulation framework is constructed to simulate the parking processes of both vehicle types and capture the macroscopic impacts of individual parking decisions on system. A genetic algorithm (GA) optimization approach is applied to determine the optimal parking pricing. The results indicate that when AVs and CVs each account for 50% of the market, distinct pricing strategies are required to achieve specific objectives. Specifically, under the objective of minimizing vehicle kilometers of travel (VKT), high parking fees should be imposed on parking lots in the city center to guide them toward adjacent areas with low prices. Similarly, achieving vehicle travel time (VTT) minimization requires implementing extremely low prices for peripheral parking lots to attract vehicles, thereby reducing congestion in central areas. Notably, the pricing strategies for VTT minimization and total utilization time (TUT) maximization share certain similarities under this equal-proportion scenario. Moreover, if the penetration rate of CVs exceeds that of AVs, parking revenue can be maximized by establishing high prices across all parking lots. Conversely, when AVs become dominant, it is necessary to lower parking prices appropriately to encourage AVs to utilize parking lots.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"166 ","pages":"Pages 87-100"},"PeriodicalIF":6.3,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579262","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}

We then employ a fractional logit model (FLM) to analyze factors influencing EV adoption rates across communities, focusing on varying impact of different public EV charging stations. Some key findings are as follows. First, we identify five clusters of public EV charging stations as follows: 1) CBD level 2 (Business level 2), Residential level 2 and DC fast charging, 3) Coastal level 2 (Tourist area level 2), 4) Urban level 2, and 5) Suburban and Rural DC fast charging. Second, LPA results demonstrate that current EV charging stations are primarily concentrated in residential and urban areas, mainly consisting of level 2 chargers. Third, our empirical model results show a significantly positive correlation between residential level 2 and DC fast charging and the proportion of EVs in nearby communities.

We consider two dual-channel structures for logistics service providers and freight forwarders: a combination of direct selling and reselling, or direct selling and agency selling. The findings indicate that an increase in cross-price sensitivity escalates selling prices within each channel and direct sales volume, but negatively impacts the agency sales volume. Furthermore, our analysis debunks the prevailing belief about pricing discrimination demonstrating that heightened consumer awareness of the direct selling channel does not invariably result in lower agency selling prices. It depends on the commission rate, which is a critical factor influencing logistics service providers’ selection of an optimal channel structure. Surprisingly, the interactive analysis demonstrates that ESG initiatives prompt logistics service providers to prefer a structure that combines direct selling with reselling. On the other hand, as the agency selling channel’s commission rate escalates, the willingness of logistics service providers to invest in ESG decreases. In summary, logistics service providers using a dual-channel structure should ensure consistent service features across channels and provide flexible transport capacity.

Relying on a sample of 89,801 migrant workers over the period 2011–2017, the results indicate that HSR significantly increases a city's allure for migrant workers, with HSR accessibility exerting a more profound influence compared to HSR connectivity. Migrants who are female, young (aged 16 to 29), unmarried, having no kids, working in secondary industry or foreign enterprises, with non-urban hukou or crossing provinces demonstrate a heightened sensitivity to both HSR connectivity and accessibility. Furthermore, the willingness to pay of migrant labor is highest for the operation of HSR, followed by improvements in accessibility, and then by enhancements in connectivity.

We propose a novel Spare Parts Condition Sharing (SPCS) policy for airlines in AMR, aiming to better align the airline's maintenance planning and service providers' capabilities. The purpose is to enhance synchronization between planned maintenance schedules and actual service delivery time and facilitate matching between required and available spare parts inventory. Empirical analysis demonstrates substantial theoretical improvements over the baseline AMR approach, with quantifiable reductions across multiple operational metrics: ferry flights, flight cancellations, delayed flights, and severe delayed flights. Furthermore, the results indicate a significant decrease in total delay time, while incurring only a marginal increase in unutilized flying time. This paper also reveals the importance of maintaining high-quality maintenance data and illustrates enhanced cost-effectiveness through increased maintenance opportunities.
