- PublikationStudying bicyclists’ perceived level of safety using a bicycle simulator combined with immersive virtual reality(Elsevier, 2021) Nazemi, Mohsen; van Eggermond, Michael; Erath, Alexander; Schaffner, Dorothea; Joos, Michael; Axhausen, Kay W. [in: Accident Analysis & Prevention]There is a need for methods that provide a better understanding of bicyclists’ perceived safety and preferences on currently unavailable and/or unknown bicycle facilities. Different survey methods have been used to study bicyclists’ behavior, experiences, and preferences; ranging from verbally described facilities to surveys including images and videos. Virtual Reality (VR) experiments blur the boundaries between stated preference (SP) surveys and revealed preference (RP) surveys and provide a realistic sense of design. This research introduces a novel research method in bicycling research and discusses the results of an experiment using a bicycle simulator combined with immersive VR. In total, 150 participants participated in this experiment and were asked about demographics and perceptions and preferences after bicycling in five different environments with an instrumented bicycle in VR. A 5 2 mixed design was used with bicycling environment as within-subject factor and pedestrian / traffic volume as between-subject factor. ANOVA tests revealed how each environment and ambient pedestrian / traffic volume affected perceived level of safety (PLOS) and willingness to bicycle (WTB). Pairwise comparison showed that participants felt safer bicycling on the segregated bicycle path compared to bicycling on the painted bicycle path on the road and roadside. There was no meaningful difference between WTB for less than 10 min and WTB for more than 10 min between bicycling on a painted bicycle path on the sidewalk and painted bicycle path on the road. PLOS and WTB ratings of men and women were not significantly different from each other. The older segment of the sample was more worried about roadside bicycling and bicycle commuters were more confident to ride on the roadside. Despite having several limitations, immersive 360-degree VR was found a powerful presentation tool to evaluate future street designs which can inform transport and urban planning.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationPsychological antecedents of mobile consumer behaviour and implications for customer journeys in tourism(Springer, 04/2018) Wozniak, Thomas; Schaffner, Dorothea; Stanoevska-Slabeva, Katarina; Lenz-Kesekamp, Vera [in: Information Technology & Tourism]As online activities increasingly shift to mobile devices, organizations especially in tourism must understand which factors drive and inhibit mobile consumer behaviour, if they want to remain competitive. Thus, this paper analyses the effects of psychological factors on mobile consumer behaviour. Drawing on multiple established theories, four psychological factors are identified: (1) smartphone self-efficacy, (2) mobile-specific innovativeness, (3) mobile users’ information privacy concerns, and (4) personal attachment to smartphone. Using a structural equation modeling approach with a large-scale consumer sample, the effects of these factors on two fundamental types of mobile consumer behaviour are analysed: behaviour along the mobile customer journey and consumers’ willingness to disclose personal data in return for personalized mobile experiences. The results confirm the relevance of the identified factors for mobile consumer behaviour. These findings have several implications for the design and management of mobile touch points in tourism.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationHow to postpone purchases of a new mobile phone? Pointers for interventions based on socio-psychological factors and a phase model of behavioural change(Elsevier, 2018) Ohnmacht, Timo; Thi Vu, Thao; Schaffner, Dorothea; Weibel, Christian [in: Journal of Cleaner Production]Due to the short life-spans of mobile phones, materials are wasted and the degradation of the environment from mineral mining increases. We examine the relationship between the socio-psychological factors that affect the status in four phases of a model of behavioural change (predecision, preaction, action, postaction) with regard to postponed purchases of a new mobile phone by using an ordered logit approach. Representative data from 1818 residents of the city of Lucerne, Switzerland, were collected. The empirical results indicate that the significant effects of socio-psychological factors on phase affiliation provide an orientation framework for the design of interventions. There is evidence that influencing perceived behavioural control to increase affiliation to higher phases by inter alia longer battery life spans, fewer updates that slow down the system, and extended options for repair and maintenance to extend the longevity of the mobile phone.01A - Beitrag in wissenschaftlicher Zeitschrift
