The sustainable development of the cities represents one of the major challenges for the future of the planet in the 21st century, relatively to the contribution and adaptation to climate change, natural resources consumption, energetic transition, population mobility, welfare and security,...

In this study we argue for a 'Big Push' in infrastructure investments in greater Europe. We propose the building of a European Silk Road, which connects the industrial centres in the west with the populous, but less developed regions in the east of the continent and thereby is meant to generate...

In dieser Studie argumentieren wir für einen "Big Push" bei den Infrastrukturinvestitionen im größeren Europa. Wir schlagen den Bau einer "Europäischen Seidenstraße" vor, welche die industriellen Zentren im Westen mit den bevölkerungsreichen, aber weniger entwickelten Gebieten im Osten des...

We develop a framework for assessing the net benefits of investments to promote bicycling, which explicitly accounts for internal costs of bicycling. We apply our model to eight Swiss cities using data from the Swiss national travel survey and find that increasing the level of bicycling by...

In economics, the regional densification of economic activity is referred to as agglomeration. The effects of agglomeration are often referred to when discussing the wider economic benefits of transportation infrastructure projects. The magnitude of these effects has not been extensively studied...

This paper explores how the interaction between human-driven vehicles (HVs) cruising for parking and autonomous vehicles (AVs) traveling back and forth affects travel behavior and congestion. To capture the spatial distribution of parking, we develop a continuous spatial optimization model, with...

We study the interaction between transit improvements and land use policies in the context of Bengaluru, one of India's largest cities. The city inaugurated a metro system in 2011. Yet it has low building heights even near metro stations, reflecting low floor-area ratio limits. We construct a...

Hypercongestion is the situation where a certain traffic flow occurs at a combination of low speed and high density, and a more favorable combination of these could produce the same flow. The macroscopic fundamental diagram (MFD) allows for such hypercongestion, but does not explicitly describe...

We use a regression discontinuity design to study the effect of the COVID-19 lockdown on mobility and traffic accidents. Based on data from Google Community Mobility reports and Uniform Traffic Crash Report from the Louisiana Department of Transportation and Develop- ment (LaDOTD), we find that...

The People's Republic of China (PRC) has made massive investments since the late 1990s in highway infrastructure, connecting its rural and urban regions. In this paper, we study the impact of highway investments on the educational choices in rural PRC. Because enhanced connectivity facilitates...
