This study examined the impacts of ride-hailing applications (RHA) on sustainable mobility, specifically, mode substitution, vehicle purchasing intention, and behavioral changes in transit use and ...active mobility, using three Southeast Asian capital cities, Bangkok, Hanoi, and Manila, as case studies for cities in developing countries. Our results confirmed that the advent of RHA generally reduced the use in public transport and active mobility which could impede transition toward sustainable mobility. The comparative analysis results revealed that the degree of impact depended on the initial adoption and/or development of that mode of transport before the advent of RHA. However, our results suggested some entry points of RHA for promoting sustainable mobility including RHA as a feeder role, RHA to improve efficiency of conventional taxi service, and RHA to reduce private car ownership.
The COVID-19 pandemic has the potential to have lasting impacts on energy and the environment at the global scale. Shelter-in-place measures implemented to mitigate the spread of COVID-19 have ...resulted in expectations for 2020 global energy demand to contract by nearly 5% with related global CO2 emissions declining by as much as 7%. Exactly how long and to what extent we will see continue to see energy demand, CO2 and related greenhouse gas (GHG) emission destruction resulting from COVID-19 is uncertain but dependent on global policy responses to the pandemic. Policy responses targeting the transportation sector, particularly ground-based transportation, can stimulate a sustainable mobility transition that mitigates the potential for long-term environmental damage.
This paper reviews and examines social and cultural dynamics of transportation and extends state-of-the-art knowledge to consider how events surrounding the COVID-19 crisis may have created a sustainable mobility opportunity though (1) avoiding unnecessary transportation volume, (2) shifting transportation norms and practices and/or (3) improving the carbon-efficiency of transportation systems. Relevant policies for a low-carbon transportation transition are considered and those most appropriate to the current context are proposed with consideration of key factors that may help or hinder their implementation success.

The sustainable governance of transport systems remains a significant challenge for policy makers worldwide, particularly in cities. Urban areas are developing rapidly from a technological viewpoint, ...and innovative technologies create new possibilities for smart mobility management. Therefore, this study investigates the relationship between the implementation of the smart city concept and the idea of sustainable transport, particularly with regard to the reduction of transport generated CO2 emissions. The study estimates CO2 emissions for different potential scenarios of development for the Warsaw transport system until 2050 using the United Nations' ForFITS (For Future Inland Transport Systems) model. The study also analyses the additional impact on CO2 emissions of smart city elements as determinants of mobility. The results show that meeting the reduction targets set by the European Union 2011 White Paper on Transport will be challenging, requiring an in-depth transformation of the transport and energy sectors. This study also confirms that smart city solutions can play a crucial role in mitigating transport emissions and meeting reduction goals. The conclusions provide important insights for the design of smart mobility governance and enhance the relationship between transport policy and research.
•The circular economy model is considered for the management of tires.•The 7Rs hierarchy applies from early stages of production to post-consumption.•Joint academic and industrial actions are needed ...for an effective tire management.•A sustainable circular economy alleviates current environmental concern of tires.
Until nowadays, the concept of the 3Rs (Reduce, Reuse, Recycle) has tried to develop responsible consumption habits. Nonetheless, the rise of ecological thinking has generated the appearance of four new Rs in addition to these basic 3Rs; the currently 7Rs (Reduce, Reuse, Recycle, Redesign, Renew, Repair and Recover) which refer to the actions necessary to achieve the change towards a circular economy (CE) model. This model aims at extending the lifetime of the resources through their rational and efficient use to generate value repeatedly, reducing costs and waste. In this review, we examine the route followed by tires from the CE perspective, analyzing end-of-life strategies that aim to improve the circular flow of tire rubber materials. We discuss the most relevant studies on the “7Rs” concepts applied to tires, comparing different scientific approaches, as well as their industrial and commercial implementation. We also illustrate the drawbacks and feasibility of each of the R-hierarchy strategies. From the early stages of production to the post-consumption step, the path that tires trail within this CE model evidences the commitment and efforts towards the development of effective management schemes for achieving a real sustainable mobility.
Problems of transport become more pressing with increasing urbanisation. Although EVs (electric vehicles) are considered to contribute to reduction of greenhouse gas emissions and local air pollution ...caused by passenger car transport, their use is still very modest.
The core objective of this paper is to identify the major impact factors for the broader dissemination of EVs in urban areas. We compare and analyse cities selected in nine different countries which are active in dissemination of EVs.
The most important recommendation for policy makers is that all monetary and non-monetary promotion measures implemented should depend on the environmental benignity of the electricity generation mix. From society's point of view the promotion of EVs make sense only if it is ensured that a major share of electricity they use is generated from renewables. Since the final goal is not just to increase the number of EVs but to reduce emissions, cities also have to consider other e-mobility options such as trolleybuses, metros, trams and electro buses, as well as promote walking and biking, especially for short distances.
•Oslo is a good example in use of EVs (electric vehicles) in urban areas.•Monetary and non-monetary measures could increase the attractiveness of EVs.•Most of the policies implemented will be abolished with the increasing number of EVs.•All environmental benefits of EVs could be reached only in combination with renewable energy.•Cities have to consider also e-mobility options for public transport.
This study proposes a new approach for dealing with the thermal management of batteries in fuel cell hybrid electric vehicles, by introducing a new concept of on-board energy storage system which ...integrates the battery pack with a metal hydride tank. The rationale behind this solution is to use the exothermic absorption and endothermic desorption processes of hydrogen in metal hydrides for heating and cooling the battery pack, respectively, thus ensuring an optimal thermal management control. An experimental investigation is carried out on a prototype in order to proof the concept and preliminary assess its feasibility for actual implementations. The results show that the system is capable to effectively control the temperature variations within the battery pack: for 1C and 1.5C constant-current discharge tests, a desorption of 30%–40% of hydrogen, over the total amount stored into the metal hydride tank of the system, allows the final average temperature of the battery pack to be around 15 °C lower than the one reached without thermal management. Moreover, it is found that the system is potentially capable of providing a suitable thermal management for more than four hours under realistic driving conditions. The proposed energy storage system also achieves inherently high gravimetric and volumetric energy densities, with theoretical values equal to 182 Wh/kg and 530 Wh/L, respectively. These estimates represent reference values for further design improvements.

The selection and prioritization of appropriate Transportation Demand Management (TDM) measures is a common problem faced by transport planners and decision makers. The problem involves many ...uncertainties due to changing economic conditions, uncertainty in project success, changes in mobility and population characteristics etc. In this study, the multi-criteria decision making (MCDM) based fuzzy Full Consistency Method-Dombi-Bonferroni (fuzzy FUCOM-D’Bonferroni) model is proposed for a case study in Istanbul’s urban mobility system. Istanbul’s historical peninsula is considered to be a pilot area for the implementation of TDM projects by the local government. The proposed model is compared with other well-known four MCDM methods in order to show its validity and consistency. The results show that public transport capacity improvements is the best alternative among the other TDM measures.
•Pull and push measures under a TDM project are identified.•Transport demand management measures are assessed.•A new fuzzy FUCOM-D’Bonferroni method for solving MCDM problem is proposed.•Economic, cost, social and environmental criteria are considered.•Different scenarios are employed for stability of results.
The Bus Rapid Transit (BRT) in the Banyumas area, Central Java, aims to provide inter-regional connectivity in Purwokerto City and Purbalingga Regency. This is one of the six BRT corridors in Central ...Java launched in 2018. Therefore, this study aims to examine the development of BRT corridors based on transit-integrated land use along the corridor, after five years of operation. The primary survey was conducted on land use along the corridor at a radius of 200 m and 400 m from the BRT bus stop, which was analyzed using a qualitative descriptive method. As a result, BRT Corridor 1 in Central Java can be identified for bus-based transit development. First, BRT services have connected high to very high populations. Second, BRT shelters have good access to shopping centers, culinary centers, and artificial tourism within a 200 m and 400 m radius. Third, BRT shelters are also connected to other modes of public transportation. However, the results of our study found that the BRT shelters had not been connected to pedestrian facilities. Based on these three criteria, BRT Corridor 1 in Central Java is feasible to be developed as a sustainable public transport service. However, further studies are needed to link BRT shelters with pedestrian facilities, in order to create clean and sustainable mobility.
