CAP4Access: Collective Awareness Platforms for Improving Accessibility in European Cities & Regions

The objective of CAP4Access is to develop and pilot-test methods and tools for collectively gathering and sharing spatial information for improving accessibility. The aim is to exploit the power of online maps and mobile devices for fostering awareness of barriers for individuals with limited mobility and in turn aid in the removal of such barriers.

CAP4Access helps integrating disabled communities into society (social sustainability), saving public resources e.g. by helping municipalities to focus expenditures (economic sustainability) and also saving natural resources e.g. by facilitating public transport use (ecological sustainability). Data sources will include citizen humans as sensors, sensors in smartphones and Public Sector Information such as data held by local administrations which are of relevance to accessibility (e.g. road surface and width, traffic volumes and speed, elevation, road works). Target groups include people requiring enhanced accessibility; grassroots initiatives supporting people with disabilities; policy-makers, planners and service providers with responsibility for the built environment; and the general public. Rather than setting up a new platform, the tools to be developed will be pilot-tested on established platforms including Wheelmap, WheelchairRouting, and the OSM.

More specifically our research group will participate in developing:

  • Collective tagging: Tools for tagging (human-as-sensor principle), annotating and facilitating the discussion of locations/places and routes/streets within the built environment according to their accessibility/suitability for individuals with limited mobility. Develop a tagging management system to support the collection of user-generated data.
  • Quality assessment of crowd-sourced data: Develop a data quality assessment and management approach.
  • Tools for integration of PSI/sponsored data in OSM based mapping platforms
  • Routing and navigation: Develop and implement a data and model for cityscape navigation for persons with limited mobility.
  • Tools targeting local initiatives for supporting awareness raising and collective action: Enabling local activities for creating awareness and initiating concrete measures for eliminating barriers for people with limited mobility.

This European project is funded for 3 years.

Third successful Wheelmap event with volunteers of SAP at Heidelberg

On Monday 09 October 2017 the GIScience group of Heidelberg university organised another Wheelmap mapping event for SAP volunteers in the course of the “SAP month of service“. Volunteers of SAP already supported the CAP4Access team in merging volunteered accessibility data (from Wheelmap.org) and expert accessibility data (from Heidelberg Hürdenlos) two years ago and by [...]

Adding Landmark based Navigation Instructions to OpenRouteService

A recently published paper (Rousell & Zipf 2017) presents a prototype navigation service extending OpenRouteService (Schmitz et al. 2008) that extracts landmarks suitable for pedestrian navigation instructions from the OSM dataset based on several metrics. In general, when providing instructions on how to get somewhere, people generally include landmarks in their instructions - “Turn left [...]

Are Crowdsourced Datasets Suitable for Specialized Routing Services? Case Study of OpenStreetMap for Routing of People with Limited Mobility

Using data generated from the crowd has become a hot topic for several application domains including transportation. However, there are concerns regarding the quality of such datasets. As one of the most important crowdsourced mapping platforms, in a recent study (1) we analyze the fitness for use of OpenStreetMap (OSM) database for routing and navigation [...]

Towards a Landmark based pedestrian Navigation Service using OpenStreetMap data

Within wayfinding and navigation tasks, the use of landmarks has been found to be a key aspect. In particular pedestrian instructions should focus on the delivery of “landmarks” to aid in navigation. Still the use of landmarks is not common in many navigation systems. The salience of features is an important aspect of whether they [...]

CAP4Access Comes to a Close

On Tuesday 17th January, the CAP4Access/MyAccessible.EU came to a close after three years with the successful completion of the final European Commission review meeting in Brussels. Reviewers were highly pleased with the outcomes of the project, both on the technical and societal fronts. At GIScience in Heidelberg, through the EC FP7 project we have extended the [...]
