Short summary Uncertainty is an important consideration when making decisions which means it is important when valuing travel time reliability in SP experiments. This study makes two contributions. First, it demonstrates how to quantify and communicate the uncertainty of quantities of interest when providing value estimates of travel time and relia...

Transport trends have been highly expansive in recent decades. Distances travelled have increased, the number of cars has grown, and vehicles have become larger, heavier and faster. The last two decades have therefore seen a thorough failure to achieve the political goals linked to climate change in the transport sector. Decisive political manageme...

Ein wichtiger Teil der Verkehrswende ist die sozial-räumliche Gerechtigkeit von Maßnahmen. Ein systematischer „zweiter Blick“ auf Verkehrswende-Maßnahmen mit einer Brille der Gerechtigkeit hilft dabei, Wirkungen daraufhin zu überprüfen, welche Bevölkerungsgruppen von einer Maßnahme profitieren oder negativ betroffen sind. Es fehlt dafür allerdings...

The project MyWay (funded by mFUND, BMDV) looked at ways to improve the mobility of individuals with diverse permanent or situational characteristics by making mobility apps more diversity-conscious. The project addressed knowledge gaps and identified barriers that could potentially reduce the attractiveness of public transportation services. Appl...

Background Commuting by bicycle or on foot is beneficial for health and wellbeing. However, cycling and walking alongside road traffic poses the risk of air pollution and noise exposure. Traditionally, exposure research is based on objective measurements. Only recently have subjective perceptions gained attention. The perceived exposure to air poll...

The COVID-19 pandemic has drastically changed mobility behaviour. Many commuters have been reduced due to the restrictions in everyday life, public transport has been avoided as a common means of transport and instead there has been a shift to private cars and walking and cycling. This article first analyses the developments and impacts of the pand...

Electric scooter sharing (e-scooter sharing) is a new urban micro-mobility service that is expected to shape individual urban mobility. The introduction of e-scooter sharing systems poses challenging questions for cities and transportation planners regarding their effects on their transportation system. This study addresses the question concerning...

Durch die Corona-Pandemie hat sich das Mobilitätsverhalten drastisch verändert. Viele Wege sind durch die Beschränkungen im Alltag reduziert worden, der ÖPNV wurde als gemeinschaftliches Verkehrsmittel gemieden und stattdessen hat eine Verlagerung auf den privaten Pkw sowie auf das Zufußgehen und Radfahren stattgefunden. Dieser Beitrag analysiert z...

The effects of the Covid-19 pandemic on sustainable mobility are diverse and ambivalent. In transportation planning and governance, promising new practices are being developed. 'Temporary cycle paths' or 'temporary limited traffic zones' have been established in several cities and it appears that these measures are here to stay. Our study analyses...

Introduction A resilient city can guarantee accessibility and mobility to its citizens and effectively mitigate adverse impacts of crises on its population and infrastructure (Holling, 1973; Holling and Gunderson, 2002). So far, the concept of ‘resilience’ has mostly been used in the context of disaster management and climate adaptation. However, d...

Städte sind der Lebensraum der Zukunft. Doch wie können sie angesichts hoher Belastungen durch immer mehr Menschen, Verkehr und Emissionen auf Dauer lebenswerter werden? Was benötigen Städte, damit Menschen darin gut arbeiten, leben und sich bewegen können? Wie können urbane Räume und urbane Mobilität nachhaltig und zukunftsfähig gestaltet werden?...

Cities are the habitat of the future. However, how can they become more liveable over the long term given the stresses resulting from increasing numbers of people, traffic and emissions? What do cities need so that people can work, live and move well in them? How can urban spaces and urban mobility be designed to be sustainable and fit for the futu...

The COVID-19 pandemic has been both a challenge and an opportunity for urban mobility. It has posed questions about sustainable spatial development, mobility, and social participation in a new way and, by demanding quick solutions, has put the working capacity of the administration and its resilience to the test. Moreover, the crisis is perceived a...

The introduction of e-scooter sharing systems is posing challenges for cities and transportation planners (Caspi, Smart & Noland, 2020). As a reaction to the partially uncontrolled and rather uncontrolled market entry of micromobility services in the United States, several cities banned e-scooter sharing systems, as a form micromobility (City of Sa...

Discussions surrounding vehicle automation have been dominated to date by technical, ethical, and legal issues. Despite its central importance, the influence of vehicle automation on the mobility transition and thus on climate and the environment has remained a subordinate topic, which Agora Verkehrswende and DLR are addressing here.

Private car ownership provides the foundation for the current dominance of the car in the modal split of many cities, regions and countries. A private car is seen by many as the fastest, safest and most comfortable means of transportation. Hence private car ownership is further increasing in both the emerging markets of development countries as wel...

In der Arbeit wird untersucht, wie Mobilitätsbenachteiligung entsteht, wer davon betroffen ist, welche Konflikte zwischen sozialen und ökologischen Anforderungen an Mobilität bestehen und wie sich diese Anforderungen vereinbaren lassen. In den Blick genommen werden dabei Menschen mit sehr unterschiedlichen Merkmalen an unterschiedlichen Orten. Ein...

It is hoped that Automated Driving (AD) will make alternatives to the private car more attractive and facilitate the transition to sustainable transport. However, this expectation may underestimate both the resistance of private automobility and the unintended consequences of automated driving. Whether AD will contribute to sustainable mobility dep...

Ziel des Projektes DiVA ist es, einen größtmöglichen gesamtgesellschaftlichen Nutzen aus der Vernetzung und Automatisierung des (Straßen-)Verkehrs dadurch zu erschließen, dass der Dialog mit relevanten Akteuren und Stakeholdern in der Gesellschaft auf eine solide wissenschaftliche Grundlage gestellt und inhaltlich sowie zeitlich strukturiert wird....

While digitalization provides a range of new mobility options, neither gender specific requirements nor role and task specific issues are part of the recent developments. Against this background, this contribution is looking into gender issues in the digitalized ‘smart’ mobility world aiming to contribute to the development of future ‘smart’ mobili...

Public transportation (PT) in combination with other active transportation modes is the key to sustainable cities and a solution against congestion and air pollution. Faced with increasing competition from the private sector and the upcoming technology of automated driving (AD), an acute challenge is ensuring a robust future perspective for PT. The...

(Überblicksvortrag zum Thema der Konferenz-Session) Automated driving is expected to radically change the mobility of persons and goods and will have impacts on urban designs and spatial planning as well as residential selection and location decisions of retailers. Regarding the increasingly accepted ideal of the livable city as being compact, walk...

Automates vehicles (AV) are expected to change the mobility of persons and the design of transport systems. Firstly, automation of individual privately used vehicles is expected to make car use more attractive as in-vehicle time can be used for other purposes than driving. Secondly, novel concepts of shared automated vehicles are expected to signif...

Hitzebelastung ist in der aktuellen deutschen wie auch internationalen Debatte zur Anpassung der Städte an den Klimawandel eines der Top-Themen. Zusammen mit Starkregen, Hochwasser oder Stürmen werden sommerliche Hitzewellen als die Klimafolgen benannt, auf die sich Städte vorbereiten müssen. Aus sozialwissenschaftlicher Sicht sind einerseits die U...

Mobilität und die Folgen einer eingeschränkten Mobilität haben in den Sozialwissenschaft en an Aufmerksamkeit gewonnen und werden zunehmend als sozialpolitisch relevante Gegenstände untersucht (Lucas 2004, 2012). Auch im Rahmen der Debatte zu Energiearmut spielt Mobilität eine Rolle, wenngleich diese im Vergleich zu Wärme und Strom bisher noch weni...

Komplexe Fragestellungen insbesondere im Bereich der interdisziplinären Umweltforschung bedürfen einer methodischen Herangehensweise, die eine größtmögliche Offenheit bezüglich der Daten und Methoden zeigt, ohne aber der Beliebigkeit zu verfallen. In diesem Beitrag stellen mit der „prozeduralen Methodik“ einen Ansatz vor, der sich dieser Aufgabe st...

In recent years, a honeybee decline has been observed that threatens pollination in agriculture and ecosystems. At the same time, a growing interest in beekeeping has been reported, especially in the metropolises and cities. We conducted a case study in Berlin and asked whether and, if so, how the beekeeping trend provides answers to the problem of...

Increasing heat stress is one of the impacts of global warming cities have to cope with and adapt to. The recent German and international debate focuses on the threat of increasing mortality rates, especially the vulnerability of the elderly people and measures to reduce it.
