The urgency to act on sustainable transport reached new levels in July 2023 when the temperatures across the globe hit an all-time high, and the promises of Automated and Connected Transport (ACT) to support meeting both the Sustainable Development Goals and reduce the effects of the climate crisis are ever more required. This chapter concludes this volume which aims at the different contributions of ACT to sustainability. It brings together the main themes and perspectives, as well as the challenges highlighted in the previous chapters. The main issues revolve around the effectiveness of environmental sustainability goals for ACT, issues of equity and social sustainability, planning, regulation and enterprise. This work largely represents a collaboration from the Wider Impacts and Scenario Evaluation of Autonomous & Connected Transport (WISE-ACT) Action funded by the COST Programme between 2017 and 2022 which brought together around 200 experts from 42 countries to discuss issues related to Autonomous and Connected Transport implementation.

The 26th United Nations Climate Change Conference of the Parties (COP26) has reinvigorated the policy focus on sustainable transport. Automated and Connected Transport (ACT) has been featured as a promising technology-based option to aid in meeting the Sustainable Development Goals (SDGs). Despite progress in certain areas of sustainability, there are still a lot of SDGs where limited progress has been observed since the 2015 Paris Agreement, particularly regarding the social pillar of sustainability which is reflected from the user perspective. This chapter will set the scene for this edited volume first by contrasting ACT potential with the SDGs and then by highlighting the requirement to focus more on addressing user needs through ACT. Remarkably, scholars have been increasingly sceptical about the transition to fully automated and connected vehicles, thus it is pertinent to highlight relevant opportunities and risks. Chapter recommendations foster the promotion of a Quadruple Helix approach to operationalise the inclusion of social concerns (e.g. gender balance and equity) in Sustainable Urban Mobility Plans (SUMP) across the world.

Transport and pandemics are interlinked given the ubiquitous nature of modern transport systems. The COVID-19 pandemic has provided much evidence for both virus contagion but also containment and how transport plays a role in both. As the world and its cities experienced lockdowns, there were travel restrictions, physical social distancing rules, transport systems shut down, changed operations, a re-opening with lower demands in some sectors (e.g., air transport and urban public transport services) and an increased demand in others (e.g., freight and home deliveries). These changes brought about a series of reactions at all levels, from governments and local authorities, operators of all transport modes but also personal and individual behaviour. This volume provides evidence on an array of transport and pandemic experiences through a collection of works from around the world, each chapter discussing a mode, a region and possible future outcomes. This introductory chapter provides the context for this volume with an overview of literature that looks at transport and pandemics, a timeline of events that marked the COVID-19 pandemic developments across different parts of the world, and finally an overview of the chapters in the volume. It concludes with some insights from the editors on the future of transport in a post-COVID world.

The COVID-19 pandemic disrupted travel patterns, use of space and modal choice. Cities took actions in a way they did not before, trying to accommodate economic and travel needs with the goal of reducing the spreading of the virus. Active travel (AT) played an important role in accommodating travel needs and in increasing the resilience and environmental friendliness of the urban transport system. As cities gradually return to their normal life, transport planners must decide which role to assign to AT in future urban plans. In particular, whether to confirm the temporary policies incentivising AT enacted to counteract the reduction in the use of public transport or to return to the previous road space allocation that dedicated considerable urban space to motorised vehicular traffic. After reviewing the empirical evidence on the AT evolution during the various pandemic phases and illustrating the main policies planned and implemented at city level in many countries, this chapter summarises the lessons learnt, derives some policy suggestions, and identifies future research needs.

Connected and autonomous mobility may be an imminent game-changing reality, still in its embryonic form, that is set to disrupt a century-long ‘driver-centric’ status quo and recalibrate transport in unprecedented and possibly entirely unexpected ways. Autonomous vehicles (AVs) may have among others, a major impact on sustainability which in an era where concerns about the urgency and magnitude of climate change threats are voiced more and louder than ever before, needs to be a positive one for helping societies to enjoy liveable futures. This might not be an easy task to accomplish, however. This chapter, using a thematically organised narrative review approach, tries to give a well-rounded answer on whether driverless technology can yield sustainability benefits (or not) by looking at all three spheres of sustainability referring to environmental, economic and social implications. Agendas like motor traffic, air pollution, energy consumption, employment dynamics, inclusion, cybersecurity and privacy are all explored, and a conclusion is derived highlighting the need to package automation with connectivity, alternative fuelling and multimodality and building it around public transport (and to a lesser extent sharing service) provision. The road to make driverless transport genuinely sustainable is ‘bumpy’ and ‘uphill’ and requires the development of an appetite not for technology excellence per se, but rather for travel behaviour change. Achieving this needs serious strategic and coordinated multi-stakeholder efforts in terms of pro-active policy reform, user (and transport provider) education and training initiatives, infrastructure investment, business plan development, and living lab experimentation.
