This chapter presents the main results of the Accessibility Instrument Survey (AIS), collecting basic information on each of the accessibility instruments reviewed in this report (for more detail on these Instruments see Chapter 3). The aim of the survey was to enable quick, objective and comparable overviews of each of the reviewed accessibility instruments. The information collected will enable the categorization of
accessibility instruments present in this research, aiming to be a reference for future categorization of accessibility instruments for planning practice. These categories will support the analysis of the coverage of accessibility instruments in this research, i.e., identify how representative this research is across different accessibility instrument types. In addition, these will be used to analyse the characteristics and concerns which
most frequently underlie the development of accessibility instruments. Finally, the survey also collects developer’s perceptions on the usefulness of their accessibility
instruments in planning practice, enabling the first insight into the main research question of this COST Action, although limited to the developer’s point of view.
In summary, the results of the survey will be used for four purposes: Development of an accessibility instrument sheet for each accessibility instrument summarizing its main characteristics (Appendix A);
Identify the coverage of accessibility instrument types present in this research (Section 4.3.1) discussing the representativeness of this Action; Provide a glimpse on the characteristics and concerns which most frequently underlie the development of accessibility instruments (Section 4.3.2); Provide a first insight into the perceived usefulness of accessibility instruments in planning practice from the point of view of the developer (Section 4.3.2 and Section 4.3.3).
The next section provides an overview of the Survey describing the information collected. This section also describes the development process of this survey including
data collection, dates and means. The results of the survey are analysed in the third section starting with a discussion on the coverage of accessibility instruments reviewed
by this research (Section 4.3.1), identifying accessibility measure types which are represented and which are absent. This discussion is accompanied by the presentation
of the main categories of accessibility instruments from the perspective of the end user.
These categories try to summarize the main concerns planning practitioners are expected to have when searching for an accessibility instrument and is built upon some
of the information collected by the survey. Following, the third section also presents a general analysis of the results (Section 4.3.2), focussing on the dominant characteristics of the accessibility instruments reviewed and on the developer’s perception of the usefulness their instrument will have for end users. The section ends with a brief cross analysis of results (Section 4.3.3) trying to identify relationships between accessibility instrument characteristics and perceptions of usefulness by developers. The fourth and last section presents the main conclusions of this study
