Understanding Bikesharing - Eine Mixed-Methods Analyse der Nutzungsabsicht von Bikesharing-Systemen in Deutschland

Fahrradverleihsysteme (englisch: Bikesharing systems, BSS) besitzen das Potential, als Teil einer multimodalen Infrastruktur zu einer nachhaltigen Verkehrswende beizutragen. Für die Gestaltung von BSS ist jedoch detaillierte Kenntnis darüber notwendig, wie es bei Verkehrsteilnehmer:innen zu einer Intention kommt, BSS zu nutzen. Die vorliegende Forschungsarbeit untersucht aus diesem Grund in einem Mixed-Methods Ansatz, welche Faktoren Entscheidungsprozesse beeinflussen, die zu einer Nutzung von BSS führen oder diese verhindern. Mithilfe eines quantitativen Datensatzes von 202 Befragten aus Leipzig und Berlin wurde auf Basis von Technikakzeptanzmodellen ein Strukturgleichungsmodell berechnet, welches die Prädiktoren Leistungserwartung, Aufwandserwartung, Erleichternde Bedingungen, Sozialer Einfluss, Gewohnheit sowie darüber hinaus Lokale Anbindung als Moderator enthält. Gewonnene Erkenntnisse wurden anschließend durch eine qualitative Befragung von sieben Personen in Form von halbstrukturierten Leitfadeninterviews ergänzt. Das Strukturgleichungsmodell erklärte 52% der Varianz der Intention, BSS zu nutzen. Leistungserwartung und Gewohnheit zeigten sich als signifikante Prädiktoren. Erkenntnisse aus den Interviews legten nahe, dass zudem Erleichternde Bedingungen eine wichtige Rolle spielen könnten. Es wird empfohlen, in zukünftigen Untersuchungen bezüglich Nutzungskontexten von BSS sowie verschiedener Nutzertypen zu differenzieren. Für die Gestaltung von BSS wird eine Förderung der Leistungserwartung durch das öffentlichkeitswirksame Vermitteln verschiedener Nutzungskontexte über den Ersatz des eigenen Fahrrads hinaus empfohlen. Ausgehend von einer Bevölkerung, welche gewohnheitsmäßig eigene Fahrräder nutzt, sollten BSS als Teil eines bestehenden multimodalen Verkehrssystems beworben werden. Eine den Radverkehr fördernde Infrastruktur, flexible Preismodelle, hochqualitative Leihräder sowie Verlässlichkeit sind darüber hinaus Aspekte Erleichternder Bedingungen, die für eine BSS Nutzung zentral sind

Learning from Covid: How Can we Predict Mobility Behaviour in the Face of Disruptive Events? – How to Investigate the Mobility of the Future

Introduction: With the beginning of the COVID-19 outbreak and the restrictions put in place to prevent an uncontrolled spread of the virus, the circumstances for daily activities changed. A remarkable shift in the modal split distribution was observed [Ank21]. Moreover, the changes in mobility during the COVID-19 pandemic had multiple impacts on road traffic [Yas21]. By now, several researchers have looked at the impact of COVID-19 as a disruptive event on mobility behaviour. This workshop within the 4th Symposium on Management of Future Motorway and Urban Traffic Systems aimed to discuss insights from these research projects and how they enable experts to transfer this newfound knowledge to future disruptive events such as climate change, rising energy costs and events related to a possible energy transition. Thus, the research question this workshop investigated reads as follows: What can we learn from the pandemic to be able to predict how different future disruptive events can shape the mobility of tomorrow

Safe or unsafe? - Analysis of policy makers' perceptions on road safety cycling measures

Urban cycling is gaining popularity worldwide. Inadequate local and international guidelines on street cycling have contributed to a significant increase in road traffic, including increased accidents involving cyclists. In parallel, worldwide, safety data indicates that low-income countries have a high average rate of traflic fatalities (27,5 deaths per 100,000 population), more than three times higher compared to high-income countries (8,3 deaths per 1000.000 population) [1]. Another study found that safety and security factors have not been sufficiently addressed in previous studies regarding bicycle mobility. These factors seem to be more relevant in developing countries than developed ones, and more research is needed [2]. ... [From: Introduction

Perceived cycling safety during Corona times - Results of a longitudinal study in Germany

With the beginning of the COVID-19 outbreak and the restrictions put in place to prevent an uncontrolled spread of the virus, the circumstances for daily activities changed. A remarkable shift in the modal split distribution was observed. Cycling was seen as a reliable and resilient option in pandemic times as it allowed social distancing and poses a low risk of contagion. There are detailed studies on the effect of the pandemic on cycling traffic all over the globe which used different data sources, like app data. counters or surveys [1] [2]. Apart from the citizens' behavioral responses to the corona pandemic, the municipalities also put up interventions that were meant to support a shift to cycling-based movements in cities. The question to discuss is what changes will be permanent and which changed circumstances, e.g. increased subjective safety, lead to a long-term change of mobility patterns. The changes in mobility during the COVID-19 pandemic bad different impacts on road traffic collisions and road deaths in different countries. While there was a reduction of both indicators in 32 out of 36 countries in April 2020 compared to April 2019, there was an increase in the other four countries [3]. Others also found a reduction of traffic fatalities in 23 out of 24 countries in 2020 compared to a baseline of the previous years (2017-2019), the only exception being Switzerland [4]. The subjective well-being has also changed differently for the different transport modes throughout the pandemic. For example, in April 2020, 9% of respondents said they would feel more comfortable or much more comfortable if they used or would use a bicycle compared to pre-pandemic times; in summer and autumn 2020, this figure was 11 %, in spring 2021, it was 13%. In autumn 2021, 15% of respondents said they would feel more comfortable or much more comfortable if they used or would use a bicycle than before the spread of the coronavirus [ 5].

More than a billion motives to focus on NMT Africa - Enhancing the quality of infrastructure to improve cycling safety and cycling culture in Africa, case in Ethiopia

Urban quality of life is measured by how clean the environment is, how safe people feel, how close they are to green spaces, and in general by the quality of outdoor space. Good quality public spaces are spaces that reduce road accidents through managing appropriately different transport modes, especially walking and cycling [1]. Cycling is healthy, economical, and environmentally sound form of mobility that is fundamental to life. More than one billion of the people in African cities walk or cycle for more than 55 minutes every day - to reach work, home, school, and other essential services [2]. One-third of the population of the African continent uses active mobility as a daily means of transport. This reveals that there is a potential of using cycling as a daily mode of travel in Africa. However, the poor quality of infrastructure for cycling sends a message that cyclists are not welcome in the urban environment. Despite the widespread use of non-motorized modes, transport planning and the provision of infrastructure in most of the cities in Africa have become carcentered, undermining the importance of cycling and walking. While the majority in the global south are active mobility users, they are not being respected by the public policies and experience 93% of the world's traffic fatalities and injuries [3]. Road traffic accidents are a major shes are not different in Africa. The World Health Organization Global Status report on Road Safety 2018 showed that the African region had 26.6 deaths per 100,000 populations, which is the highest among all regions [5]. Sub-Saharan Africa still has the highest per capita rate of road fatalities of any region in the world. Unfortunately, in most cases, the victims of traffic casualties are primarily pedestrians and cyclists [6]. Much of that is linked to the neglect of the infrastructure needs for pedestrians' and cyclists' safety. [From: Introduction
