This report is the sequel to the previous report “Literature review of indicators of accessibility” (Reumers, Hermans, Janssens, De Jong, & Wets, 2011) and provides an interpretation of the in the literature review proposed indicators of accessibility for Flanders. The indicators proposed in the literature review were divided into four major aspects of accessibility, i.e. transport, land-use, policy and context, to ensure a sound and comprehensive theoretical representation of accessibility. In the current report the same division is held.


The purpose of this report includes quantifying the current situation in terms of accessibility in Flanders. The complete quantification of the set of indicators by data collection leads to a rich overview of the accessibility situation in Flanders. From this overview, a set of indicators can be chosen for the monitoring of accessibility in Flanders. This final set, including the baseline measurement of that set, will be determined in a subsequent report. Based on that measurement, the report may be applied to evaluate the evolution in accessibility (trends) in the future, by performing a similar quantification in a structural manner. Using the indicator values, the effects of accessibility initiatives could be evaluated separately, leading to a purposeful accessibility policy and an efficient use of accessibility budgets (Hermans, 2009; Litman, 2005, 2007).


The second chapter of this report is a rich collection of indicator values. It provides the latest Flemish figures, and Belgian figures in the absence of Flemish ones, for the 228 indicators of accessibility that were presented in Reumers et al. (2011), and shows where or by whom the indicators are recorded and published. The presented figures originate mainly from publicly accessible online resources. Indicators for which Flemish figures are only partly available or unavailable are also evident from this baseline measurement. The applied research method, namely the consultation of electronic resources on the internet, implies that there may be additional data sets that are not included in this report. Indeed, the possibility exists that not all relevant documents were found on the World Wide Web or that some data is available but not accessible via the World Wide Web.


The demand for transport and the transport supply are currently largely quantified, but often there’s a lack of recent figures, multiple references are needed for the fullest possible interpretation or figures are only available at the federal level. Indicators regarding the confrontation between transport demand and supply are rarely quantified, recorded and published covering the entire Flemish territory. The demand for land-use and activities is (partly) quantified. But quantifying the supply, and the confrontation between supply and demand, for Flanders is still no sinecure. With regard to policy, currently quite some figures are collected, although again different references are needed to rule for all modes or for all aspects of the indicator. Temporal limits, weather conditions and technology are contextual aspects of accessibility for which indicator values are only limitedly available. However, the Flemish economy, socio-demography, ecology and the individual restrictions in Flanders are largely quantified.


Many of the 228 accessibility indicators from Reumers et al. (2011) are currently being quantified in Flanders. This provides a rich set of indicator values, from which a final set of indicators that together form a view on the current degree of accessibility in Flanders can be determined. However, there are some indicators for which data collection is not yet (systematically) performed or for which it is currently limited to data collection at the federal level. This is especially applicable to federal matters (e.g. railways). Finally, one can conclude that different credentials are needed to come to this rich collection of indicator values.
