The pilot study approached traffic environments as semantic constructions to explore the meaning-making processes that shape road users' perceptions of and interactions with traffic environments. Conducted in a basic driving simulator, the study involved eight participants who viewed a pre-recorded video of a driven route, paused at six pre-defined...
Design representations are important tools for designers in the design process. To help designers choose the appropriate representation, taxonomies have been proposed based on type, degree of fidelity, and when to use them. However, Design representations may also play an important role in designers' communication with users and enabling users as c...
The purpose of the study was to investigate how drivers use assisted and automated driving systems (DAS), more specifically their usage of SAE Level 1 and Level 2 systems, in different situations. An online survey was distributed to 2500 respondents in China, Germany, Spain, and the USA. The final dataset consisted of 549 respondents, all non‐profe...
The term service design refers to a collection of techniques, methods and activities that, among other things, aim to ensure that services are developed according to a clear understanding of what users want. Mobility as a Service (MaaS) has been pitched as a user-centric approach to resolving problems related to passenger transportation, and yet se...
Despite widespread interest, empirical research on how end-users perceive and use Mobility-as-a-Service (MaaS) is scarce. To address this knowledge gap, this article analyzes the end-user process of adopting a MaaS service entitled EC2B, which was launched in Gothenburg, Sweden, in the spring of 2019. The contribution to the MaaS literature is thre...

The pro...
Due to the argued benefits of passenger comfort, cost savings, and road safety, the bus sector is showing increasing interest in advanced driver-assistance systems (ADAS). Despite this growth of interest in ADAS and the fact that work tasks are sometimes complicated (especially docking at bus-stops which may occur several hundred times per shift),...
Mobility as a Service is generally discussed as a way to improve transport’s ecological sustainability by e.g. reducing private car ownership/use. However, there is also concern that it may shift users from public transport to shared car modes, and from active to non-active modes. The argued (mainly positive) impacts are largely based on informed a...
Aim
This study identifies and compares perceptions of autonomous vehicle (AV) implementation among three Swedish stakeholder groups: Future Users , Urban Planners , and Developers.
Method
Semi-structured comparative focus groups were conducted separately with each of the three groups of stakeholders and the transcripts were analysed in broad theme...
As connected, electric, and autonomous vehicle (AV) services are developed for cities, the research is conclusive that the use of these services must be shared to achieve maximum efficiency. Yet, few agencies have prioritised designing an AV system that focuses on dynamic ridepooling, and there remains a gap in the understanding of what makes peopl...
With the introduction of automation, vehicles have become increasingly complicated and difficult for users to understand. Users’ understanding of Automated Vehicles (AVs) is a key aspect for safe and successful implementation of AVs. However, more research is needed into how users understand AVs based on actual use experience. In this paper, users’...
Users’ acceptance, and subsequent adoption, of automated vehicles is likely affected by the understanding they develop of the vehicle based on its driving style properties. This paper explores how driving style properties – as a type of tangible attribute – are perceived by users, and how they affect users’ interpretations of AVs. 18 participants e...
Extant levels of automation (LoAs) taxonomies describe variations in function allocations between the driver and the driving automation system (DAS) from a technical perspective. However, these taxonomies miss important human factors issues and when design decisions are based on them, the resulting interaction design leaves users confused. Therefor...
This study analysed a series of workshops and explored prerequisites for interdisciplinary co-design among industrial designers, design engineers and users in the development of a novel medical device. Presented as a case study, this paper focus on what affects participants’ transformative processes towards genuine participation in co-design proces...
Highlights:
-Characteristics of everyday traffic situations have an effect on the users trust in automated vehicles (AVs).
-It is paramount to consider situational aspects such as perceived risks (for oneself and others), perceived task difficulties and that the AV conforms to the user’s expectation.
-Trust is the result of an interaction betwee...
Mobility-as-a-Service has been argued to lead to more sustainable mobility, but dissemination has hitherto been slow. Private and public actors have raised concerns as to the actual ‘market’ for MaaS as well as the desired effects. Based on an analysis of an excerpt of available literature, the paper attempts to provide tentative answers to the fol...
Automated Driver Assistance Systems (ADAS) are designed to support the driver and enhance the driving experience. Due to ADAS limitations associated with the driving context, the intended use of ADAS functions is often non-transparent for the end-user. The system performance capabilities affected by the continuously changing driving context influen...
At present, many policymakers and practitioners are searching for actions that could facilitate Mobility as a Service (MaaS) developments. A potential action, which has received a lot of attention, is to introduce Intermediary MaaS Integrators; that is intermediate actors that assemble the offerings from Transport Service Providers (TSPs) and distr...
