In this context, adequate models and simulations are key to estimating the impact of potential MaaS implementations and support decision-making to reap the benefits MaaS could bring. This article aims at reviewing MaaS representation in existing academic literature pertaining to transportation modelling, in order to assess its progress and identify trajectories for future improvements. We do so by considering mobility as an economic system in which MaaS interacts with both travel demand and supply. After identifying an adequate set of indicators to analyze MaaS models, we review 31 contributions and find out that most studies consist of demand-centered usage models while the integration of the system's supply side's operational and profitability factors is still lacking, especially in-MaaS financial flows.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"39 ","pages":"Article 100368"},"PeriodicalIF":2.2,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212012224000273/pdfft?md5=2310529996f333579ec20ce90ca1c0b0&pid=1-s2.0-S2212012224000273-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141595757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for observing environmental gains, there should be inter-modal substitution from polluter modes to the HSR. This paper analyzes the impact of new HSR openings on car traffic, using a Generalized and Staggered Difference-in-Difference approach. Unlike previous studies, we analyzes the entire Spanish HSR network. We matched the georeferenced data on car traffic with the origin–destination routes provided by Google Maps API to estimate the impact of the HSR on car traffic. We found that the HSR has not generated modal split, except for few of the HSR segments, in which we estimated a 6%–8% reduction in the annual average daily traffic. These results have public policy implications for the transport policy in the EU, and the effectiveness of decarbonization policies.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"39 ","pages":"Article 100360"},"PeriodicalIF":2.8,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212012224000194/pdfft?md5=a4d887a5383e5364f30b9076157cf85c&pid=1-s2.0-S2212012224000194-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141314861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While some of these empty trips can be attributed to load imbalances, it is common to observe the flow of empty trucks in both directions of a route. This paper introduces a microeconomic model aimed at providing a deeper understanding of the flow of empty vehicles beyond load imbalances and its implications for freight flows, transport prices, and the number of carriers in the free-entry equilibrium. Our approach captures shippers’ preferences when selecting carriers within a system comprising two locations with cargo flow in both directions. The model incorporates price competition among carriers and the production of differentiated services, as shippers perceive carriers’ services in a heterogeneous manner. Given that carriers lack knowledge of shippers’ preferences, these are represented using a random utility model. The model enables the determination and comparison of equilibrium conditions with the social optimum. The results show that: (1) The transportation of goods results in not only empty vehicles due to imbalanced loads but also a natural occurrence of empty vehicles due to the stochastic demand patterns. (2) When a new carrier enters the market, it contributes to the negative impact of empty vehicles through the business stealing effect. (3) Empty trips disrupt the balance of prices and carriers, creating a gap between the free-entry equilibrium and the socially optimal values. (4) By coordinating carriers’ operations, the flow of empty vehicles due to the business stealing effect can be minimized, moving the system towards the socially optimal outcome.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"39 ","pages":"Article 100361"},"PeriodicalIF":2.8,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141294731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emergence of aggregation platforms can alleviate the problem of market fragmentation. However, the poor regulatory level of the aggregation platform poses numerous issues, such as low vehicle and driver compliance rates, prominent safety hazards, and difficulty for passengers to claim their rights, which distract passengers to a great extent. Thus, this paper proposes an optimization model that considers the impact of the regulatory level of the aggregation platform on heterogeneous travelers. At the uppermost level, the aggregation platform determines the appropriate regulatory level and charges RS companies a commission fee. In the middle level, RS companies determine the optimal trip fare. The travel choice of customers is modeled as the lowest level. The study provides reference to regulate the aggregation platforms.</p></div>","PeriodicalId":45761,"journal":{"name":"Economics of Transportation","volume":"37 ","pages":"Article 100343"},"PeriodicalIF":2.8,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212012224000029/pdfft?md5=aa0f69359d0c9706c3e94e6cd9a32452&pid=1-s2.0-S2212012224000029-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139749130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
