Survey and analysis methods and technologies
In addition to taking into account ecological and economic aspects of sustainable, active mobility, the health effects of actively travelling to work for employees in companies form the core of ActNow. Building on the GISMO project and other research results from MdZ, ActNow aims to demonstrate the full potential of active mobility in the context of commuting to work and the associated everyday routes, in particular those that accompany children, and to realise this in the test area of Salzburg and Upper Austria as well as in individual large companies throughout Austria. The application of evidence-based planning methods and planning tools is another integrative component of the project. An intersectoral policy board will accompany the ActNow project.

While large joint widths for pavements are desirable from the perspective of drainage, they are undesirable from the perspective of walking comfort and wheelchair accessibility (Grimm 2018). In the course of a master's thesis written at the Institute of Transport, the topic of barrier-free use of of road surfaces was investigated in terms of good rollability with wheelchairs (Aigner 2020). A new measurement method was developed and tested for this purpose. The basic hypothesis of the method is that there is a correlation between the objectively measurable physical quantity of acceleration and the resulting jerk on the one hand and the subjective perception of wheelchair users on the other. To test the hypothesis, a wheelchair was equipped with a mobile phone as an accelerometer. The wheelchair equipped in this way was driven over 14 different street surfaces in the city centre of Vienna and the accelerations were measured. Eleven people who are dependent on a wheelchair in everyday life drove on nine of these surfaces and evaluated their barrier-free rollability. Despite the relatively small sample, it can be assumed that the presumed correlation between physical measured variables and subjective perception exists. Accordingly, the accelerometer is a suitable method for assessing the accessibility of surfaces in public spaces.
The study pursues several objectives. Firstly, the test method developed in (Aigner 2020) is to be validated in more detail and checked with regard to its possible applications in practice (WP1, WP3). Among other things, the influence of the wheelchair type and the steering wheels, which was largely excluded in (Aigner 2020), will be investigated. Based on this, a criterion for barrier-free rollability is to be derived with the help of extensive measurement tours (WP2) as a function of joint width, slab size and evenness. Finally, paving materials commonly used in Vienna will be evaluated with regard to infiltration and barrier-free rollability with the help of this criterion (WP4).
The NTN project addresses the question of how sustainable mobility behaviour - walking, cycling and the use of public transport - can be established as the norm in everyday practice. NTN promotes the understanding of existing mobility practices, explores possible transformation paths from niche to norm and uses these findings in a co-design process with politics, administration, interest groups and citizens. Three Lower Austrian cities - Korneuburg, Stockerau and Fischamend - are used as case studies. Both qualitative and quantitative research methods will be used to investigate how sustainable mobility behaviour can be initiated and controlled. In accordance with the Lower Austrian Mobility Concept 2030, the aim is to promote sustainable mobility in the cities and to achieve a shift in the modal split from private motorised transport to environmental transport in the medium term.
At the next consumer wxpenditure survey (2019/20), the Institute for Transport will be cooperating with Statistik Austria to gather information on time use and travel behaviour over one week in a sample of about 1000 persons in addition to consumer expenditures. As part of the survey, the activity level of the individuals is also recorded in detail. For this purpose, the diary and the personal questionnaire will be adapted accordingly.
The Austrian Transport Model is essential for national transport planning and forecasts as well as basis for scientific works and political decision making. Starting in 2019, an updated version is planned. Task 4 is dealing with the development of an appropriate data collection methodology (combining revealed and stated preference surveys) to collect and evaluate freight transport data as input for the new transport model.
Autonomous vehicle (AV) trials are currently taking place worldwide and Europe has a key role in the development of relevant technology. Yet, very limited research exists regarding the wider implications of the deployment of such vehicles on existing road infrastructure, since it is unclear if and when the transition period will start and conclude.
It is anticipated that improved accessibility and road safety will constitute the primary benefits of the widespread use of AVs, whilst co-benefits may also include reduced energy consumption, improved air quality or better use of urban space. Therefore, the focus of this COST Action is on observed and anticipated future mobility trends and implications on travel behaviour, namely car sharing, travel time use or residential location choice to name a few. Other important issues to be explored under different deployment scenarios are social, ethical, institutional and business impacts.
To achieve this, it is essential to culminate co-operation between a wide range of stakeholders at a local, national and international level, including academics and practitioners. Consequently, this COST Action will facilitate collaboration within Europe and beyond about this emerging topic of global interest.
