Potenziale und Risiken von automatisiertem Fahren für die Mobilitätswende

Potenziale und Risiken von automatisiertem Fahren für die Mobilitätswende Der Verkehrssektor verursacht rund 20 % der Treibhausgasemissionen in Deutschland. Um Klimaschutzziele erreichen zu können, sind in diesem Sektor grundlegende Veränderungen notwendig, die unter dem Begriff Mobilitätswende zusammengefasst werden können. Automatisiertes Fahren könnte eine Transformation der Mobilität unterstützen und Chancen für eine nachhaltigere Mobilität bieten, beispielsweise indem Fahrten gebündelt, intermodale Mobilität attraktiver gestaltet und Fahrzeuge effizienter betrieben würden. Auf der anderen Seite sind mit dem automatisierten Fahren jedoch auch Risiken verbunden, die sogar zu einem Anstieg des motorisierten Individualverkehrs und den damit verbundenen Emissionen führen könnten. Die Vorlesung beleuchtet Chancen und Risiken von automatisiertem Fahren

Small and Light Electric Vehicles: An Analysis of Feasible Transport Impacts and Opportunities for Improved Urban Land Use

Improvements in battery technology have resulted in small and light electric vehicles (LEVs) appearing on the market in Europe since 2011—however, their market share is still comparatively low. Low energy requirements and small size can potentially contribute to sustainable mobility in terms of climate protection and reduced local emissions. Our study evaluates how three-wheeled and four-wheeled vehicles, categorised as L-Class according to Regulation (EU) No 168/2013, can contribute to more efficient use of space in urban areas. Evaluations of expert interviews, an extensive literature research, and analyses of the German national household travel survey (MiD) serve as the basis of the study. First, the substitution potential of trips through LEVs is explored using MiD data. Our findings show that between 17% and 49% of trips made and 6% to 30% of the distance covered by private trips can theoretically be substituted by LEVs. Thus, reorganisation of current land use offers potential and additionally, LEVs are an attractive and sustainable addition to other means of transport and contribute to achieving the climate protection goals of the transport sector. Due to the fact that technology application is restricted by travel behaviour and political support, our study discusses possible support by public bodies towards sustainable mobility. Here, the promotion of LEVs in combination with restrictive measures for cars is necessary

Small electric vehicles – benefits and drawbacks for sustainable urban development

Small electric vehicles (SEVs) have the potential to contribute to climate protection, efficient land use and mitigation of air pollution in cities. Even though, they show many benefits that could enhance urban quality of life, they are not yet widely used. In this paper benefits as well as drawbacks for these vehicles are discussed by combining literature research and outcomes of a mixed-method approach with expert interviews and an online survey. Resulting from these arguments a vision for SEVs in urban areas is drawn showing them integrated in a mix of various transport modes. Environmental benefits are derived, for example, from their lower weight and low maximum speed making them a more energy efficient transport option than heavier cars. Additionally, the small vehicle size lowers land use for SEVs and e.g. allows for less parking areas needed. However, they also hold constraints that need to be dealt with in different ways. On the one hand the lower safety compared to passenger cars is an issue that is further worsened by current traffic regulations. On the other hand costs in terms of purchase prices seem to be an issue for SEVs

An Inter- and Transdisciplinary Approach to Developing and Testing a New Sustainable Mobility System

Sustainability research is frequently tasked with the development of concrete solutions that can be directly applied to socio-environmental problems as such this paper presents and discusses an inter- and transdisciplinary approach to developing and testing a mobility-on-demand-system in a “real world laboratory” set up in Schorndorf, Germany. This paper addresses the following questions: (1) How can stakeholders be involved in the research and development process and become co-designers? (2) What are the suitable ways of supporting and facilitating interdisciplinary exchange and joint work at different places? The main contribution of this paper is the description of a methodological approach. It thereby reflects on the process of inter- and transdisciplinary work in the development phase and pilot operation. In addition, a joint working document, a so called “Specification Book”, is utilized to facilitate teamwork and enable the exchange of scientific knowledge within the team. The experiences in the project are also reflected upon and specific recommendations are determined. The paper further reflects on the possibilities and challenges of the methodology and provides recommendations for its application. The originality of the paper lies in its description and reflection of a method that goes beyond the participation of users in the design phase of the project

Potentials of Light Electric Vehicles for Climate Protection by Substituting Passenger Car Trips

For the transformation of the mobility sector, small and light electric vehicles (LEV) show great promise, owing to their efficiency and low vehicle weight resulting in low energy consumption and lower greenhouse gas emissions per driven kilometer. The presented study focuses on the theoretical potential of substitutability of passenger car trips in Germany by varied LEVs based on the “Mobilität in Deutschland 2017” (“Mobility in Germany 2017”) dataset, for the year 2030. A detailed approach for identifying substitutable car trips was developed, reflecting age, trip purpose, number of passengers, and other decision criteria. By conducting a life cycle assessment of the considered LEVs and passenger cars, potential emission savings were analyzed. In the considered baseline scenario, it is found that emissions could be reduced by 44 % with 50% of passenger car mileage being substitute by LEVs. This study, thereby, gives way to further research on LEVs, and would urge both policy makers and general users to steer towards comprehensive measures that encourage a switch from cars to LEVs

Fields of applications and transport-related potentials of small electric vehicles in Germany

The possible applications of small electric vehicles, i.e., electric cargo bikes and three- and four-wheeled L-class vehicles in transport, are discussed, and potential business models are presented. Moreover, transport-related potentials are analyzed. Therefore, we have utilized a multi-method approach: we conducted qualitative interviews with experts and professionals in the field of light and small electric vehicles and carried out quantitative analyses with the national household travel survey mobility in Germany 2017. Our results show that, theoretically, small electric vehicles could be used for 20–50% of private trips (depending on the model). On these trips, however, they would not only replace car trips, but also trips on public transport or by bicycle and on foot. In commercial transport, these vehicles are particularly suitable for service trips and some last-mile deliveries. If small electric vehicles were to replace a significant share of the transport volumes of motorized passenger and commercial transport, they could contribute to climate protection
