Cyclists that weave past cars, get cut off and honked at. Pedestrians that rush across streets at short traffic lights and appreciate the shady trees in the nearest traffic-calmed zone. Noise and visual impressions that rush up to us and stayin our minds until we reach our destination. Active mobility is more than mobility that serves the purpose of getting from point A to point B. It is both healthy and dangerous, liberating and restrictive, mundane and recreational, relaxing andnerve-wracking. It is an up and down, a roller coaster, not only of positive emotions but also of stress.Stress and emotions are increasingly the subject of research, particularly within the scope of reurbanisation.Reurbanisation concerns well-being, freedom from stress and, in the broadest sense, the (mental) health of the urban population in their everyday life and in their mobility. Cyclists and pedestrians, in particular, have direct contact with thebuilt environment and the diverse influences that affect them: noise, heat, emissions, other people and means oftransport. Active mobility is gaining importance in the wake of the climate crisis and the desired mobility turnaround,and has become the goal of sustainable urban and transportation planning. The latter is also increasingly recognising the relevance of the interaction between people and space, as well as the subjective, emotion-related factors of mobilityas an essential aspect of mobility behaviour. In mobility research, these factors are taken up in mobility surveys. From mobility diaries, surveys and GPS tracking, to sensor-based recording of emotions in active mobility, a wide range of methods has been used, without resulting in the creation of a comprehensive assessment tool. The latter, also called“human sensory assessment”, involves the measurement of physiological signals using sensors. These physiological signals (such as changes in skin conductance) can provide information about a (negative) experience (e.g., walking orcycling) and thus make subjective experiences quantifiable. A brief moment of stress can show up physiologically as asweat lasting but a few seconds, thus becoming measurable. In this way, the invisible and the subjective aspects of emotions and stress become visible and objective. However, these measurement methods of “human sensory assessment” are still far from being used in the practical (transportation) planning field. Reasons for this vary from insufficient technical solutions, the high effort required and the question of data reliability. In addition, there are ethicaland data protection requirements that need particular attention and clarification. Nevertheless, the method holds enormous potential for planning processes and brings a new perspective to transportation planning on the basis of objective, evidence-based data. After all the data has been collected, all technologies have been tried, and many(human) sensors have been used, the question remains: What is applicable in planning and can be implemented as are design in space to promote active mobility in the background of the mobility transition?The aims of the work were, among others, (a) to classify and describe relevant theories and concepts of emotion psychology, urban and transport planning in relation to stress and emotions and their genesis. Emotions were described and classified in the context of urban space and active mobility from the perspective of traffic and urban planning and psychology. A further goal was (b) to analyse international research on the topic of “human sensory assessment” inorder to identify, among others, gaps in applicability as a starting point for own research. (c) Methods of “human sensoryassessment” with a focus on skin conductivity were presented and analysed on the basis of case studies (own, realisedresearch projects). Finally, (d) the method of “human sensory assessment” was reflected with experts and potentials with regard to the planning and design of public spaces (critical examination, chances, potentials, application requirements) Methodological approach: The work aimed to employ a mix of methods based on an explorative research approach,given that the work explores a novel or, thus far, little-researched issue. In addition to the presentation of the genesisof “human sensory assessment” and a systematic literature analysis, the analysis of two case studies including interviews with participants (realised research projects, n = 67 and n = 5) illustrates the application in the research-related field.As an essential qualitative method, guideline-based interviews with experts were realised. Their focus lay on the role of emotions and stress in research and practice, as well as on the applicability of “human sensory assessment” in (transportation) planning processes.The results can be summarised along the objectives as follows:A. Emotions and stress remain a marginal issue in transportation planning, but are gaining importance. New (sustainable) means of transport and the importance of active mobility as a contribution to the mobility turnaround openup new questions on the subjective, emotional factors of mobility, which have thus far only been consideredrudimentarily. “Human sensory assessment” – a field which emerged about 10 years ago – addresses these issues asa new research direction and bears the potential to bring emotions and stress derived from physiological data inconnection with the built environment into transportation planning. Nevertheless, the process faces the challenges of unclear terminology and insufficiently integrated theories across disciplines.B. Analysing the national and international field on “human sensory assessment”, it can be observed that previousstudies show limitations, with a clear genesis already noticeable from the initial projects. This also allows conclusionsto be drawn about future developments. The following limitations can be identified: a) no random selection of participants,b) small sample size, c) no medically certified wearables, d) no supplementary user surveys and e) lack of orintransparent ethical clarification. In addition, it is possible to identify insufficient analytical depth and exploitation of the method’s potential.C. The two case studies examined were able to partially address the identified gaps in the literature review and focuson users, visualisation and ethical concerns. In this regard, FB 1 – with the goal of identifying critical locations on thefootpath – recognised, among other things, that a) the presentation of results via a visualisation platform, which brings together different data sources (including stress data) was considered useful for the research team and also for practicalplanners, b) when comparing the different data sources, some are consistent but do not always agree, c) participants who agreed to take part in the field tests were mostly affluent and well-educated, and d) wearables on the wrist were considered less annoying than the chest strap by the participants. Therefore, it can be concluded that they are more likely to be accepted.In FB2, the applicability of the wearable devices for children was tested in order to identify any traffic safety-relateddeficiencies on their way to school. In this regard, the study recognised, among other things, that a) the wearables are fundamentally suitable for children and that data collection is possible and that b) they can be operated independently by parents and children, but c) no traffic planning action requirements could be derived from the data, for example, due to the small sample. In addition, d) ethical concerns could be fully addressed.D. The expert interviews made clear that the added value and opportunities of “human sensory assessment” are seen,especially as regards visualisation, data objectivity and potential comparability. “Human sensory assessment” can benefit from the increasing importance of active mobility, as well as from more wearables suitable for mass use and theneed for higher data density for planning decisions. The conceptual intersection of “human sensory assessment” witha planning process shows that the method can tie in with different steps. For example, possible applications include thesurvey of deficiencies, the identification of critical points in the pedestrian and bicycle infrastructure and the before andafter examination of infrastructural planning. Major applications of the method are seen particularly in traffic safety.However, “human sensory assessment” is still far from being used in practice, and basic or applied research as well as interdisciplinary collaboration is still needed. In order for data from “human sensory assessment” to be taken into greater account in planning, its acceptance must be increased (on the part of users, practice), the technology, smartphoneinterfaces and data accessibility must be simplified (on the researchers’ side), and access to wearables must be madeeasier (cheaper, more practical, “mainstream tools” on the users’ side). It remains to be seen to what extent the topicof “human sensory assessment” will remain present in the research landscape, establish itself and diffuse into transportplannin
