In jüngster Zeit wird die Verteilung des öffentlichen Straßenraums durch verschiedene Akteur:innen vermehrt diskutiert und problematisiert. So wird die vermeintliche Dominanz des motorisierten Individualverkehrs (MIV) kritisiert und eine Umverteilung des öffentlichen Straßenraums gefordert....

This paper considers the impact of the introduction of a metro network in the Copenhagen metropolitan area. Using travel surveys from years before and after the opening of the metro network, we observe a significant change in travel times, speeds and mode choice for commutes that can completely...

The following article summarises the first results of a two-part study on consumption patterns in Denmark and leisure travel in Greater Copenhagen in particular. The study aims to map direct (e. g. free time travel) and indirect (e. g. goods and services) energy use related to different types of...

In the last years, sustainable travels have included bike tourists visiting cities to enjoy cultural and urban environments. Yet, when considering cycling tourists' intra-destination trips by motorized vehicles, the extent of greenhouse gas (GHG) emissions could reduce the sustainability of...

Institutional weaknesses limit the capacity of local governments to support efficient urbanization in developing countries. They also lead to the emergence of large developers with the clout to build entire cities. This paper analyzes the urbanization process when local governments are weak and...

African cities are growing at an extraordinary rate. Unfortunately, many cities are growing so fast that national, provincial, and city governments cannot manage how they develop or assure the provision of the services people need. This has many negative consequences for national and city...

This study of African fare payment systems seeks to understand the emerging payment landscape in public transport in Sub-Saharan Africa, identifying key trends and their implications. The research draws on case studies undertaken in five African cities-Cape Town, Kigali, Lagos, Maputo and...

Purpose: Goods flows in cities increase due to urbanization and growing e-commerce. Deliveries become more fragmented and more difficult to consolidate and control. This leads to an ever-increasing strain on urban infrastructure and logistics systems. With our work, we aim to design a...

Purpose: Inner-city freight transports are characterized by numerous deficits, such as congested infrastructure and increasing emission and noise levels. Sustainable urban logistics is a field with many concepts to improve the efficiency and sustainability of these transports. However,...

Purpose: The importance of urban logistics is on the rise. On the one hand, the population in cities is growing due to urbanization processes. On the other hand, there is a significant increase in the flow of goods (e.g., a boost in online purchases). Such changes are leading cities to face...

Mobilität ist eine zentrale Voraussetzung, um am gesellschaftlichen Leben teilzunehmen und liefert einen wesentlichen Beitrag zu einer hohen Lebensqualität. Gleichzeitig ist der städtische Personen- und Güterverkehr ein Hauptverursacher von Luftverschmutzung, Lärm und Flächenverbrauch....

We propose a theory-inspired measure of the accessibility of a city's center: the size of the surrounding area from which it can be reached within a specific time. Using publicly-available optimal routing software, we compute these "accessibility zones" for the 109 largest American and European...

This paper analyzes how gasoline price is related to the time workers in the US spend commuting by private vehicle, public transport, walking, or cycling. Using data from the American Time Use Survey for the years 2003-2019, and collecting data on gasoline price by state and year, we find that...

In this work, we present a gridded dataset about land cover, population density, real estate, and transportation in 192 worldwide urban areas representing together 800 million people. While population density and land cover are secondary data extracted from the GHS-POP and the ESA CCI databases...

Subsidization of urban public transportation systems is often motivated by economies of scale and second-best considerations such as an underpriced road alternative. We model a public transit line subject to frictions between users, users and vehicles, and vehicles. We derive the profit- and...

This paper examines the effects of changes in downtown parking supply on urban welfare, modal choice decisions and urban spatial structure using a spatial general equilibrium model of a closed monocentric city with two transport modes, endogenous residential parking and a form of bottleneck...

We measure the impact of Mexico City's Bus Rapid Transit (BRT) system on air quality. Through a difference-in-differences strategy with staggered adoption of treatment, we show that the BRT is associated with important reductions in the concentrations of pollutants related to nitrogen oxides....

Madagascar remains to exploit agglomeration economies and urbanization economies to sustain more rigorous economic growth. After several political and economic crises, Madagascar restored its modest but steady growth path with an average growth rate of 3.5 percent in the last 5 years (before the...

Particle-phase polycyclic aromatic hydrocarbon (PAHs) accounts for a large proportion of hazardous compounds in PM2.5 derived from vehicle emission. This study aimed at determining the profiles of PAHs based on tunnel measurement and urban roadside observation. The real-world vehicle emission...

In this paper, we study the commuting behavior of citizens living in or near a city who must decide how to get to work. Such citizens can always use their own car and drive to work. However, they can also take public transport to work. The two public transport options we consider involve taking...

One of the industries with the fastest growth rates worldwide, and notably in Thailand, is medical tourism. With connections to Cambodia and Laos, Ubon Ratchathani is located in lower northeastern Thailand, close to Vietnam and Myanmar. Therefore, there is a significant chance that this region...

The aim of the project "Implementation and further development of the GLI:X - Green Logistics Indicators in South Africa" was to build on the results and successes achieved in the previous GLI:X projects I-II and to further develop and apply the GLI:X indicator system developed within the...
