As part of the MyAccessible.EU project, CAP4Access funded by the European Commission, has produced a number of tools aiming at improving accessibility for people with reduced mobility and raising awareness to the challenges faced by those people with regards to getting around everyday environments.




Wheelmap is an initiative of CAP4Access partner Sozialhelden e.V. It allows users to find accessible places – shops, cafés and restaurants, museums, doctor's offices etc. – on an online map covering the whole world. If the wheelchair-accessibility of a place has not been reviewed yet, users are invited to tag places themselves using their smartphone, tablet or desktop computer. In 2015, Wheelmap has been further improved by adding a feature for tagging and displaying the availability of accessible toilets within buildings intended for the public. The search interface has been enhanced to allow people to look for accessible toilets in the vicinity of their current location. In addition, Wheelmap can now also be included as a so-called widget on third parties' websites, i.e. it can be seemlessly integrated e.g. on the web presence of a municipality or service provider.

Wheelmap Tango App


This app applies Google’s Tango technology to the objective of making crowd-sourcing of accessibility data more exact, easy and appealing to lay persons. Tango uses computer vision to enable smartphones and tablets to detect their position relative to the world around them without using GPS or other external signals, thereby allowing developers to create applications including physical space measurement, environ-mental recognition, and augmented reality. The Wheelmap Tango app exploits the technology’s unique capabilities to enable anybody to measure accessibility features such as door width, the slope of ramps, height of steps and floor space in toilets — all of which can be done by a few clicks on the smartphone or tablet. The measurements (augmented to photos taken) are then automatically uploaded to Wheelmap, where they are instantly made available to the large Wheelmap user community. The Wheelmap Tango feature has already been included in the standard Wheelmap app for Android, which is available from appstores such as Google Play.


Obstacle Tagging Tool


The MyAccessible.EU Obstacle Tagger service is a method of recording and viewing obstacles in the outside world. By combining an Android app and a webmap it is possible for anyone to easily mark obstacles they encounter and share these with others. And by linking with OpenStreetMap, the information that is shared can be used to make other services better suited for people with restricted mobility, such as the OpenRouteService.

The App is the tool that allows you to tag an obstacle as you are moving around. It is available for the Android platform. The app can be used offline, but an internet connection is required to upload the obstacles you tag to the viewer and to download base maps for the area you are travelling in. 

The primary means of viewing what obstacles are present in a particular area. 

Open Route Service Wheelchair Routing


OpenRouteService is a route planning online service with a profile that has been particularly made for wheelchair users. Similar to other route planning tools, OpenRouteService shows you possible routes from A to B. If you set OpenRouteService to the wheelchair profile, the service shows you the shortest route between A and B that is feasible for mobility restricted people. For this purpose it is also possible to set personal preferences that the online service should consider, such as the surface types you can move over comfortably, the maximum amount of slope the route should have as well as the maximum height of kerbs that are on the path. Besides suggesting routes from A to B the service can also show areas that can be reached from a given location within an amount of time that can be set by you.

Wheelchair Navigation App


The Wheelchair Navigation App is an Android navigation tool that makes use of the wheelchair routing provided by the OpenRouteService to navigation a person from their current location to a desired destination. This destination can be selected from Wheelmap locations, local public toilets, or can simply be searched for within the app. Not only does it provide routes that aim to be suitable for wheelchair users based on preferences entered by the user, it also delivers instructions in a format that is easier for pedestrians to understand by making use of local landmarks within the instructions.


Visualization Dashboard


The Visualisation tool allows you checking out how many wheelmap tags are on the map that you see on your current screen. Beyond the overall number of wheelmap-tagged objects it also shows you the number of red (objects not accessible), green (objects accessible), orange (objects partially accessible) and grey (objects not yet evaluated) tags. When you zoom into or out of the map, or move the map in any direction, the corresponding numbers will be updated. You can choose among various graphical diagrams in order to visualise the numbers.
If you want to learn how many points on the map were newly tagged, i.e. received a non-grey value, during the day or hours of a specially organised mapping party, you can do that! Just provide the dates of the period of interest and you’ll receive the numbers and graphics restricted to this requested interval. In a similar way, by just providing one date, you can check how many new tags were received from a certain date to present, or in the past up to a certain date.

As an example, the following figure shows the newly received tags during October 13, 2015, in some area close to Heidelberg. The number within a coloured circle stands for the actual number of tags of its kind (green, red, or yellow) within the closer surrounding of the circle. For example, the yellow circle at the top of the map with a figure „9“ inside serves to represent a total of 9 yellow tags within its surroundings. The pie-chart diagram shows the percentages of all wheelchair tags of the visible map with regard to green, yellow, red and grey. (The actual map is “bigger” but has been truncated for editorial reasons.)

Kerb Data Integrator


Mobility-impaired pedestrians, such as wheelchair users or people with walking frames or rolling walkers, have significantly different demands regarding information about their physical environment than car drivers and non-impaired pedestrians. This is due to their usually lesser physical abilities when it comes to e.g. taking one or more steps, mastering slopes up- or downwards, or driving on a narrow sidewalk. The data integration task of CAP4Access is trying to make useful data available, e.g. about slopes or features of the sidewalks, which can then be utilized by the accessibility-aware routing and navigation algorithms developed in the project. As a prerequisite, such new data must then be integrated into the Open Source and Open Data platform OSM (Open Street Map).

The problem is that these kinds of data are usually not available, and if affirmative not available for being published as open data. Fortunately, the City of Vienna, one of the four pilot sites of CAP4Access, is a notable exception and one of the most advanced Open Data protagonists worldwide. They provide a treasure trove of data potentially relevant for our project. We have so far utilized their data set about dropped kerbs, including their heights, covering the whole city area.

OSMatrix is a web-based tool that allows for understanding the development of mapping information in OpenStreetMap in a region of interest. This tool has been extended to support sidewalk attributes.  For the purpose of planning for data collection, this tool can give a general statistics of which area within a city requires more attention. The main users of this tool is expected to be planners and organizers of mapping events as well as people who are interested to know how good is the quality of OpenStreetMap data in terms of its completeness.

Quality Assurance Editor


OSM Quality Assurance Editor is an Open Source tool for querying and visualizing OSM data in a way that the results of the query could be checked per object. This tool has been extended in CAP4Access project to support sidewalk attributes that are relevant for Wheelchair routing purposes. Using OSM QA you can check the completeness of sidewalk attributes in your neighborhood and enrich the dataset by providing information that are missing. This would later allow you to make better use of OpenRouteService and consequently the Navigation App.

The source code is completely open and available via github. Or follow this link to check out the editor.

Map My Day


MapMyDay, an awareness raising campaign initiated on the occasion of 2015's International Day of Persons with Disabilities, has a twofold purpose – first to gather as much information on the wheelchair accessibility of places worldwide in a short period of time and second to raise awareness for accessibility issues among a broad, global audience. The tools deployed for the purpose included a website featuring a localisable map, a “social wall” displaying all social media posts using the #MapMyDay hashtag, and a long list of testimonials in advert-style from prominent supporters. The MapMyDay brand and set of tools continue to be used for global promotional campaigns, the latest of which was run in celebration of the World Tourism Day, which in 2016 focused on the theme of accessible tourism.
