It is a measure of how friendly, healthy and liveable the countries are, in addition to providing many social, environmental, and economic benefits. Walkability is considered as an important element in assessing cities to be green and sustainable. People in the Mediterranean countries, where their cities have narrow streets, which are difficult to access, not always with easy services, have similar cultures and traditions such as the habit of daily walking. A significant number of daily trips are made by foot. However, the walking environment in Alexandria city is limited, unsafe and inconvenient. Mainly, pedestrians are secondary to vehicles causing transportation congestion, pollution, source depletion and increasing statistics of obesity. Therefore, this paper is a chance to find solutions for decreasing the number of vehicles in the streets by converting the short trips into walking tours. This paper proposes to establish a new theoretical basis for walkable green city (WGC) indicators to measure the walkability and the greenness in Mediterranean countries. The case study was conducted on Ramleh Station district in the city centre of Alexandria city with analytical analysis using geographic information system program (GIS). The results showed that the study area is not considered as a walkable green district, despite the fact that it has many potentials that could be exploited. Briefly, the results help to prove that WGC indicators are able to measure how walkable and green any Mediterranean country is.","PeriodicalId":281606,"journal":{"name":"Urban Transport XXV","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124016305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MaaS is still surrounded by uncertainties: its development and applicability are mainly centered in developed countries; however, we believe that MaaS is modular, adaptable and applicable to several realities. In this sense, this study aims to examine university student’s demand and predisposition for MaaS usage in a developing country, as well as to understand the differences in mobility perception among those students who are car users and non-car users. This survey was applied to over 300 university students in a Brazilian city, Lavras. Using the CART algorithm, we obtained classification trees to predict favorable responses related to MaaS use, based on several predictor variables (socio-economic characteristics, means of transport used, distance, etc.). We observed that car users are a little less sensitive to cost than non-car users. For car users, the commute alternatives that take longer, with less flexibility and availability – even when offered at lower cost – are not appealing, while the non-car users accept alternative options and expend more time when lower costs are available. Also, in general, a tree-based classification model predicted a positive adherence possibility for a MaaS scheme for both car users and non-car users (69%). As conclusions, this study suggests that there is a predisposition to accept the MaaS model for creating value for commuters in a developing country. We found that many MaaS characteristics (e.g. payment via app, transportation integration, monthly plan, customization, and so on) presented a positively predictable possibility of substitution, especially for Millennials. Also, we found that bicycles may be a mode that can be explored for MaaS schemes worldwide, and that hitchhiking could be used as a strategy to apply MaaS in places where public transportation lacks efficiency.","PeriodicalId":281606,"journal":{"name":"Urban Transport XXV","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131670807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nicolaï, Arthur De Miranda Neto","doi":"10.2495/UT190161","DOIUrl":"https://doi.org/10.2495/UT190161","url":null,"abstract":"With mobility becoming a key factor affecting citizens’ well-being and quality of life, innovative schemes such as peer-to-peer (P2P) ride-hailing and Mobility-as-a-Service (MaaS) could have significant impacts on the urban commute. Furthermore, the insertion of autonomous vehicles (AVs) promises a positive impact on cities’ transit worldwide. Ergo, companies are now combining bundles of products and services emphasizing their “sales of use” rather than of products: such integration may be realized by having multi-sided business platforms. The purpose of this study is to create future scenarios for AV business platforms within urban mobility contexts. Based on an exploratory descriptive qualitative research design, we collected data on academic and grey literature. Four scenarios were plotted with real-world examples currently present in urban mobility cases, extrapolated to a future reality where AVs are considered a transport mode: (A) business-to-consumer (B2C) autonomous ridesharing; (B) P2P autonomous ridesharing; (C) B2C multimodal mobility; (D) B2C + P2P multimodal mobility. Scenarios A and B entail unimodal mobility via autonomous ridesharing, whereupon in the former, a single firm owns a fleet and subsidizes the consumer segment, while in the latter, ordinary peers own the AVs, which are offered to other peers via Uber-like applications. Scenarios C and D entail multimodal mobility from point X to Y, where in the former, a single firm owns the multimodal fleet and subsidizes the consumer segment, while Scenario D offers a bundle of B2C and P2P solutions under the MaaS paradigm. We conclude that in scenarios A and B, value creation can be solely explained by business platforms theory; while in scenarios C and D, business platforms theory is tied to business ecosystem theory, to explain value creation and distribution. Lastly, besides the unlikelihood of scenario C, any of the other three have the potential to become a reality when AVs become an urban transport mode.","PeriodicalId":281606,"journal":{"name":"Urban Transport XXV","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124232005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
