Abstract:Information and Communication Technologies, or ICT, have rapidly emerged as an integral element of everyday life, interacting in an essential manner with mobility and the activity patterns that engender it. The current paper reflects upon this trend and the opportunities and challenges it represents. Given more than three decades of research in the domain of interactions between ICT, activity decisions and travel choices, we acknowledge the elaborate, disruptive and often unexpected ways along which ICT interact with society. To support the objective of the ADB20 Committee, namely to support and promote the emerging research questions, we identify a number of technological, societal and behavioral trends related to ICT and mobility that are likely to be major driving forces for activity-travel behavior considerations in the next 15 years. Those include democratization of technology; personalization; shared and commoditized mobility; automation; data as the new currency; next generation connectivity, including 5G; evolving social media and socialization; new forms of shopping; digital twins; activity fragmentation; and multitasking. We also observe that inevitably, the increasingly interlocking relationship between ICT and mobility will bring challenges related to balancing efficiency vs. redundancy and resilience, ensuring transparency, susceptibility to malicious activities and tackling the digital divide. We argue that those should not be seen as barriers to realization of the ultimate benefits for society, providing that the transportation research agenda maintains focus on the evolution of ICT and rigorously explores the related impacts on activity decisions, travel choices and, more broadly, on transportation systems.
