Rooftop photovoltaics (PV) systems are often underestimated in their decarbonization potential due to technical, economic, and social barriers. However, rapid advances in PV technology indicate that rooftop PV could play substantially more roles than generally thought, particularly by coupling with EVs as batteries (“PV + EV”). We conducted a techn...

This poster is designed to present to the transport research community the wide existing body of work and potential future applications of the method of System Dynamics (SD) within transport research. We introduce the reader to the basic concepts of the SD method, and discuss previous reviews of academic SD pa-pers, before setting out a systematic...

This paper offers a critical review of three coevolving socio-technical paradigms: (a) “data-driven urbanism”, (b) digital platforms and (c) “Mobility-as-a-Service” (MaaS). It explores the complex relationship unfolding between data-driven cities and digital platforms, while drawing on MaaS as a case to discuss the challenges of implementing mobili...

Visioning has been widely adopted in transport planning as a method to support explorations of possible future transport systems over a long time horizon. There are vast variations in how visioning is applied but given a clear association between visions and the long-time perspective, it is unclear how these processes handle uncertainty surrounding...

The COVID-19 pandemic and associated measures to contain its spread have impacted public transport ridership in cities around the world. In Thailand, the government issued 41 Royal Decrees between April 2020 and December 2021 to mitigate the spread of the pandemic. We investigate in this study how Bangkok's public transport services (bus, metro, an...

This paper provides a review of the literature on ride-hailing applications (RHA) in Southeast Asia (SEA) to enhance the understanding of RHA’s impacts on the urban transportation sector and to inform related planning and regulatory efforts in the context of developing countries. The conceptual framework is based on the stakeholder approach, which...

The novelties of new mobility solutions, such as carsharing, may instill different expectations and understanding of the concepts among stakeholders. These differences in their ‘mental models’ can hamper the wider implementation of the concept and delay a transition toward a more sustainable transport system. In this study, we implemented a partici...

Consensus on carbon accounting approaches at city-level is lacking and analytic frameworks to systematically link carbon mitigation with the Sustainable Development Goals are limited. A new accounting approach anchored upon key physical provisioning systems can help to address these knowledge gaps and facilitate urban transitions.

Cities have become the focus of global climate mitigation efforts because as they are responsible for 60-70% of energy-related CO2 emissions. As the world is increasingly urbanized, it is crucial to identify cost-effective pathways to decarbonize and enhance the resilience of cities, which ensure the well-being of their dwellers. Here, we propose a...

The building and transport sectors in urban areas are the main contributors to global greenhouse gases (GHG). However, estimating and mapping the GHG emissions from these two sectors has been challenging, largely due to data limitation. In this study, we demonstrate how our framework can support the estimation and mapping of the daily carbon emissi...

Global greenhouse gas (GHG) emissions continue to rise rapidly despite the urgency and the high-level commitment to address climate change. The stagnation is highly apparent in the transport sector, in which more than 95% of the energy consumed by the sector is from fossil fuels. Past studies have elucidated how interactive simulation and participa...

An important issue for policy makers and transport planners who wish to promote Mobility as a Service (MaaS) initiatives is to find out whether and to what extent citizens are willing to adopt this new mobility concept. In general, young people are supposed to be the early adopters of new technologies and innovative services, but are they among the...

In the face of an emerging and novel pandemic, perceptions of its danger and probability of being affected can influence how an individual take precautionary actions. We performed an exploratory study to examine how travellers perceive the risk-related to COVID-19 and how the outbreak has affected their commuting and non-commuting travel activities...

Formulating a transport master plan for a regional city in a developing country can be a challenging task. Regional cities are often lacking financial resources or have limited expertise in the field of transport. Consequently, they are more likely to experience transport problems as they undergo expansion. The tradition of transport planning for r...

The ageing of the population poses mobility-related challenges worldwide. The emergence of new transport services that utilise technological innovations allows for new, more convenient ways to provide demand-responsive transport services in areas with limited or no regular public transport service. The question is how the features of these new serv...

A new age of mobility is upon us, and the way we analyze our transportation network and future development projects must move into this new age. Large-scale changes to our transportation system are coming with the introduction of disruptive technologies and services like autonomous vehicles, electric vertical take-off and landing (eVTOL) air taxis,...

Given the innovative nature of Mobility-as-a-Service (MaaS), various uncertainties are surrounding the possibilities for implementing MaaS. This includes uncertainties about alternative MaaS-system functionalities, about how the implementation of alternative MaaS systems might affect the overall transport system performance and about the preference...

Mobility-as-a-Service (MaaS) is an innovative transport concept that combines a range of transport modes and services to provide a user-orientated service via a single interface. Since its emergence, MaaS has drawn increasing interest within and beyond the transport sector for its potential as an innovative and potentially effective solution to urb...

The prospects of Mobility-as-a-Service (MaaS) as a potential solution for mobility has inspired a high level of interest from various transport sectors. Nevertheless, the concept is still in its early stage of development with limited evidence to support its anticipated benefits. Moreover, there are many uncertainties surrounding MaaS that may re...

How can we plan for Mobility-as-a-Service given the uncertainties surrounding its implementation?

--- Open Access http://www.cogitatiopress.com/urbanplanning/article/view/931 --- Mobility as a Service (MaaS) is a recent innovative transport concept, anticipated to induce significant changes in the current transport practices. However, there is ambiguity surrounding the concept; it is uncertain what are the core characteristics of MaaS and in w...

The tradition of transport planning in Thailand began as recently as 1960 with the Greater Bangkok Plan, and the 1971 Bangkok Transportation Study. Since then the country has incrementally developed its transport planning practice. This paper provides a detailed description of Thailand's transport master plan for urban areas and its study process....

http://www.sciencedirect.com/science/article/pii/S2352146517306579 This study reviews the perceptions of Chiang Mai city's transport decision makers in relation to the development of the local transport system. The objective is to gain an insight into their views of the city's transport problems, sustainability, and possible mitigations to solve th...

Compared to cars motorcycles are potentially the more sustainable means of transport. Motorcycles need less space, consume fewer resources, and pollute less than cars with typically low occupancy. Thus, can the promotion of motorcycles potentially improve the sustainability of urban transport systems within an Asian context? The objective of this s...
