During the last few decades, rising intra-regional volumes of trade as well as air passenger traffic have been key characteristics of Asia-Pacific’s economic development. Although conceptual and empirical linkages between rising levels of trade and air passenger flows are often assumed, relatively little is known about the potential causality in these parallels. In this chapter, we seek to empirically uncover this causality through the application of heterogeneous Time Series Cross Section Granger causality analysis for the period 1980–2010. Four scenarios are found amongst the different country-pairs: (1) there is no co-evolution, implying that both patterns develop independently (e.g. Japan–Australia); (2) there is ‘real’ co-evolution in that both patterns influence each other through feedback loops (e.g. South Korea–Philippines); (3) air passenger traffic is facilitated by trade (e.g., South Korea–Philippines); or (4) trade is facilitated by air passenger traffic (e.g. Australia–Malaysia). Some possible interpretations of this heterogeneity are discussed.

This chapter focuses on how to leverage public transport infrastructure to produce walk-friendly environments, positioning public transport as a walk-enhancing mode. What are the steps that public transport operators can take to create walk-friendly environments? Do more comfortable waiting conditions result in stronger loyalty from the existing customer base and stronger buyout from new customers? This novel approach stemmed from a partnership with the public transport operator Transdev on a real-life experiment in Grenoble to provide a more comfortable walking and resting experience for public transport users. Named Carrefour de Mobilité (‘the crossroads of mobility’), the experiment prototyped urban design interventions to enhance the access and waiting experience of users engaged in mixed-mode commuting. An ex ante/ex post evaluation was deployed to ascertain whether walk-friendlier environments encourage a more intensive use of public space and easier shifting between public transport modes. The findings show that when users perceive dedicated infrastructure as walk-friendly, they consider it more visible and more attractive, and find it comfortable enough to spend longer waiting times there. The evaluation would have benefited from an extension of the perimeter covered by the sensor technology measuring system which was not feasible because of budget constraints. The experiment reached out beyond the initial target public and captured children and older women as well, providing an amenity which was lacking for these groups and resulting in a livelier and more diverse environment for everyone. This lean and low-cost experiment shows that activating public space near public transport hubs enhances their attractiveness in the eyes of the public transport users.

The landscape of European cities is by no means homogeneous. Nonetheless, the same type of conflict has repeatedly occurred in different places in the last few years: From Seville to Vienna, from Cologne to St. Petersburg, planned high-rise buildings for inner city districts have provoked fervent arguments and debates. Whether and how European cities should integrate more high-rise buildings is a highly controversial question. This chapter focuses on strategies of vertical construction and related debates about the cityscape in both Paris and Vienna. By studying the urban constellations of Paris and Vienna, it can be shown that what may look comparable at first glance is the outcome of highly different strategies and histories.

Although both cities define themselves to a wide degree with reference to historic structures, the image of tall buildings varies drastically in these cities, which correlates with these cities’ diverse histories and hence experiences with high-rise buildings. Path dependencies and the ways individual cities receive international trends are crucial to understanding processes of urbanization. Based on in-depth interviews with various urban actors and other relevant qualitative data, this chapter aims to demonstrate that a city’s high-rise strategy cannot be attributed to any single factor; rather, it is the result of a complex interplay between various aspects and actors, which crucially includes present and past struggles over cityscapes and therefore over urban spaces.
