A recent explosion of research on the travel behaviour of the millennial generation has found that compared to past generations they are taking longer to get a driving license, driving less, owning fewer cars and using transit more. Yet these findings are not universal with some countries seeing increases in driver licensing, little change in driving or reductions in public transport use. Most past research has explored wider social and economic explanations for these trends, such as income constraints and delays in adult life transitions. Very few studies have examined the role that local context plays in explaining the change (or the lack of change) in millennial travel behaviour. This paper aims to compare how trends in young adult travel behaviour differ across diverse city contexts. It uses a comparative descriptive analysis of household travel surveys from cities in three countries (UK, USA and Australia), focussing on auto-miles and transit-miles travelled. We find that each city experienced markedly different trends in young adult travel behaviour that are unlikely to be explained by economic differences alone. We suggest that changes to the transport systems in these cities are likely to be playing an under-recognised role in shaping travel behaviour. We suggest that further research should pay greater attention to the role of the transport system in supporting changes to travel behaviour among the next generation of young adults. • Explores travel behaviour of millennials in 6 areas of the UK, USA and Australia • Macroeconomic trends impact car use among millennials. • Some evidence life stage is impacting travel of millennials. • City investments in transit likely play an important role in these trends.

Abstract: The aims of this paper are to review the current practices of car parking standards in the UK, the USA, and the Kingdom of Saudi Arabia (KSA); to draw the main lessons learned from experiences of the UK and the USA; and to suggest suitable improvements in the standards of car parking requirements in the KSA. The paper follows a comparative approach in reviewing car parking standard requirements according to different types of land use in the UK, the USA, and the KSA. The article illustrates that transportation planners in the UK and the USA use parking policies, especially the application of car parking standards, along with other planning and transport measures to promote sustainable transport choices, to reduce reliance on cars, and to reduce traffic and air pollution. Local authorities in the UK and the USA have moved from requiring minimum standards for car parking to maximum standards. The aim of maximum parking standards is to decrease the number of trips made by private cars whilst seeking to maintain and enhance the viability of economic centres and support sustainable development. In the KSA, authorities still adhere to minimum car parking standards. Moreover, the car parking requirements are not correlated with city zoning systems. The paper concludes with some thoughts on how to improve the current parking requirements in KSA cities. [Copyright &y& Elsevier]
