Methods for collecting data on mobility behaviour
Methods for collecting data on mobility behaviour
Methods for collecting data on mobility behaviour include surveys, manual and automatic counts, the usage of existing data sources and methods for pooling and jointly analysing different data sources. Our work focuses on the advancement of travel surveys methods, data processing and analysis. We conduct written, face-to-face, telephone and online surveys. We have expertise in drawing and processing representative samples. Testing and integrating innovative technological solutions such as GPS-based data is a major part of our work. Our goal is to improve the quality of the collected data, to decrease respondents’ burden and survey costs and to allow for longitudinal survey designs
The household travel survey Österreich Unterwegs is the first survey in twenty years to provide representative data on mobility behaviour of Austrian residents. This extensive database combined with the lessons learned from the survey procedure form the basis for the project AEIOU. In a first step a review of the surveys process, summarizing the main conclusions regarding data survey, data processing, weighting and data analysis, as well as a characterization of the database, will be given. Also part of the review is a quantitative and qualitative characterization of the database and the deduction of potential improvements for future surveys. Simultaneously, possible fields of applications for the available data will be explored. A distinction will be made between research questions that can be answered with the already existing dataset and subjects for which secondary data is required.
To evaluate the feasibility and usability of the survey data from the perspective of data users experiences from specific applications will be collected, evaluated and analysed. Therefore a test application inspired by transport demand modelling will be developed and feedback from external users will be gathered within expert-panels. Another key aspect of the study is the development of an indicator-set as well as a monitoring-strategy, based on the database of “Österreich Unterwegs”. They can be used as high-quality evidence base in decision-making processes. A SWOT-analysis will be applied to evaluate the strengths, weaknesses, opportunities and risks involved with the practical use of the indicator-set.
The in-depth data analysis, the description of new potential applications, the evaluation of the usability and the development of an indicator-set are combined to tap the full potential of the survey. Therefore it will be shown how the benefit from the survey can be increased by refining the data during data processing on the one hand and by combining and complementing the data with data from other sources on the other hand (generation of additional value). In addition to availability and quality checks of external data, costs and data protection aspects will be considered as well. Building on the insights gained, results will be summarized and in a concluding synthesis. Modifications in data acquisition concerning the survey content and method are suggested to extend the specific applicability of the data. Moreover, a closer look will be taken at how data availability of hitherto rarely considered groups of persons in the mobility sector can be improved by complementary surveys.
This project focuses on the systematic promotion and facilitation of active mobility (AM) (i.e. walking and cycling including the combination with public transport use) as an innovative approach to integrate physical activity (PA)
into individuals’ everyday lives. In contrast to sports or exercise, AM requires less time and motivation, since AM
provides both convenience as a mode of transport, and a healthy lifestyle. As such it has potential to reach parts
of the population which have not been receptive to the appeals and benefits of sports and exercise.
The objectives of the project are the following:
- The project will review the literature on AM and identify innovative measures and systematic initiatives to promote AM as well as traffic safety interventions.
- A longitudinal study will be conducted to evaluate the ongoing AM initiatives combined with traffic safety interventions to better understand correlates of AM and their effects on overall PA, injury risk and exposure to air pollution.
- An improved user-friendly tool for more comprehensive health impact assessment (HIA) of AM will be developed.
- The tool will be applied to AM behavior observed in the case study cities and allow the assessment of health and economic impacts of measures.
- The project will also produce a compendium of good practices of AM promotion aimed at decision makers, implementing authorities, businesses, civil society organizations and end users.
- Findings and progress reports will be communicated to diverse target audiences, including policy makers, practitioners, researchers and end-users, through a number of media, i.e. reports, journals, brochures, web-content, workshops and presentations.
The change in the culture of mobility makes it ever more important to assess multimodal transport services in terms of their efficiency, but two requirements are so far missing in this regard: data for long-term mobility behaviour over at least one week and a method for the analysis of multimodality in these data. Now, a long term mobility survey will be available for the first time in Austria as part of an FWF-project. ULTIMO aims at taking the opportunity to create these requirements: (i) a method for the automated recognition of trip purposes in GPS trajectories to enable fully automated and burden-free long-term surveys of the travel behav-iour; and (ii) a method for analysing the relationships between multimodal transport services and their demand.
