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.
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.
Responding to pressing problems arising from growing urban populations and mass motorization, municipalities need to take action. The resulting conditions include congested cities, poor air quality and quality of life. Providing contextual conditions and thereby increasing the amount of small electric vehicles could help reduce land use and improve air quality. Based on outcomes of expert interviews and an online survey, the status-quo of antecedences and barriers as well as potential measures for the implementation of small electric vehicles on a municipal level is outlined. To get an international and comprehensive view, experts from the USA, Asia and Europe participated. Results show that there are several obstacles that have to be overcome on local, national and international levels. For local policymakers especially, there is an array of measures available. The combination of push and pull measures is one key element. In this way, infrastructural changes, financial incentives, strategic implementations and soft measures to raise awareness could help the process of a market take-off immensely.
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.
