In this study, we consider the introduction of new mobility services and technologies into the megacity of Beijing, China, as per developed strategy and action plans, in order to investigate their potential contribution to sustainable mobility. This includes population relocation (decentralization), the construction of new rail lines, the introduct...

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...

Introduction: In this paper we consider system dynamics (SD) modelling of tradable transport permit schemes (TTPS). TTPS are complex and uncertain, having not yet been implemented beyond experimental trials anywhere in the world, yet have for some time been suggested as an efficient and equitable policy response to reducing car-based travel and its...

This paper considers how the implementation of a tradable credit scheme (TCS) may be used to reduce road traffic and to contribute to the formation of liveable cities and global climate change commitments. The concept of applying TCS to individual road transport is familiar to transport researchers as a measure to regulate congestion and reduce tra...

Introduction Transport and health are complex, evolving and interacting systems, which are increasingly influenced by new and emerging data forms. In this study we address the research question, “How could New and Emerging Data Forms improve understanding of mobility behaviours, and the related health outcomes, of different population subgroups?”...

Introduction The impacts of transport on health have been extensively studied, yet there has been less focus on the complex interactions that exist within the transport-health sphere. We adopt a System Dynamics (SD) approach to addressing the research question “Where are the trade-offs and synergies between different types of health impacts within...

The explosive growth of New and Emerging Data Forms (NEDF) has enabled profound new insights into human behavior, especially related to mobility. NEDF are facilitated by technologies such as smartphones, sensor networks and distributed computing architectures, which are all becoming increasingly advanced and widespread. NEDF, which may offer large...

Connected and automated vehicle (CAV) technologies and services are rapidly developing and have the potential to revolutionise the transport systems. However, like many innovations, the uptake pathways are uncertain. The focus of this article is on improving understanding of factors that may affect the uptake of highly and fully automated vehicles,...

Transportation systems and related policies are com- plex and cross-sectoral, covering different socio- economic and management aspects, and involving multiple stakeholders (such as users, operators, and public policymakers). Mobility and accessibility are central to economic and societal well-being, yet the process of doing so may have significant...

High quality, reliable data and robust models are central to the development and appraisal of transportation planning and policy. Although conventional data may offer good ‘content’, it is widely observed that it lacks context i.e. who and why people are travelling. Transportation modelling has developed within these boundaries, with implications f...

Successful development of “Mobility-as-a-Service” (MaaS) schemes could be transformative to our transport systems and critical for achieving sustainable cities. There are high hopes for mobile phone applications that offer both journey planning and ticketing across all the available transport modes, but these are in their infancy, with little under...

Road vehicles are becoming increasingly automated and connected due to rapid technological progress and digitalization trends. Vehicle connectivity might improve automated driving (AD) in various ways. The EU project “AUTOPILOT” develops, tests and evaluates different services and use cases of AD focusing on the potential of Internet of Things (IoT...

The deployment of zero-emission vehicles has the potential to drastically reduce air pollution and greenhouse gas emissions from road transport. The purpose of this study is to provide evidence on, and quantify the factors that influence, the European market for electric and fuel cell car technologies. The paper reports the results of a stated pref...

This paper focuses on three main topics: the impacts that automated transport may have on cities in different scenarios, the impact mechanisms, and the methods to develop and discuss impact paths. We describe methods to break down the complex question of the impact of automated driving on society. By decomposing the impact into smaller impact areas...

A nested logit model was estimated from a survey carried out among European car owners. For the purpose of improving choice assumptions, this model was embedded within the Powertrain Technology Transition Market Agent Model. This system dynamics model focuses on vehicle powertrain uptake in the European Union. This paper describes the modeling proc...

Road vehicles are becoming increasingly automated and connected due to rapid technological progress and digitalization trends. Vehicle connectivity might improve automated driving (AD) in various ways. While the benefits of convergence of sensor-based technologies and connected-vehicle communications are relatively well analyzed from technological,...

The objective of this study is to quantify factors influencing people’s car type choices in Europe to support the consumer choice component of the Joint Research Centre’s Powertrain Technology Transition Market Agent Model. At the core of the study are stated choice (SC) experiments undertaken with 200 vehicle owners in each of the six European cou...

The work presented here demonstrates the potential of new generation data arising from innovative policies (based on persuasive technologies) in the transport sector. Improved understanding of the spatial distribution of health impacts arising from the introduction of new travel initiatives will support more targeted and efficient policy developmen...

Purpose: In this study, we consider the European electro-mobility market from an industrial perspective, and focus on effects of market conditions and manufacturer strategies, with the objective to gain insight on what could inhibit the successful market penetration of electric powertrain vehicles. Methods: We use the EC-JRC Powertrain Technology T...

In this study, the results of a new survey on attitudes and preferences towards electric vehicles are reported. In addition, these results are compared with those of a similar survey conducted in 2012, so that the evolution of preferences towards electric cars by European drivers can be mapped.

We are interested in what policy insights can be transferred from EU countries that have been most successful in introducing EVs to those that are debating policy options. As we use a model to explore this, we are also interested in the application of modelling, seeking to understand if real world policies and results can be replicated in a model a...

Recently, the European Union (EU) adopted the Directive on the deployment of alternative fuels infrastructure, which defines minimum requirements on alternative fuels infrastructure build up, including recharging points for electric vehicles. Moreover, the European Commission is currently working towards a Communication on decarbonising the transpo...

In this paper we seek to understand the relative impacts that policies and incentives focused on e-mobility may have on the technology market shares for passenger cars, and the associated fleet energy requirements and greenhouse gas emissions. We have a European Union (EU) wide focus, and from this deduce what recommendations could be provided for...

This paper presents results from a segmentation analysis of the emerging market for Electric Vehicles (EVs). Data has been sourced through the application of a self-completion household questionnaire distributed over two cities in the United Kingdom (UK). A two stage cluster analysis methodology has been followed to identify market segments in a da...

Global concerns about climate change, as confirmed at COP21, have led to lower carbon emissions environmental policies, particularly in the road transport sector. Through an empirical analysis of low carbon vehicle (LCV) policies in California, this paper contrasts the findings from diverse distribution theories between income quintiles - used as a...

This research contributes to discussions about policy interventions to stimulate the transition of vehicle technology. Concentrating on passenger cars, an extensive system dynamics based market agent model of powertrain technology transitions within the EU up to 2050 is employed.
