Survey data collection is now over. You can still submit your answers, but it is unlikely for them to be used in the research.

Some details (if you want to know a bit more)

This research is carried out by Alexander Kachkaev, PhD student at School of Informatics, City University London and is supervised by Professor Jo Wood. The knowledge and experience gained from the questionnaire will be useful when implementing a new pedestrian routing algorithm, which will be made freely available at the end of the project. The answers are released under a free license (CC BY 2.0). No personal data is being collected and stored; the source code of the app is available on Github.

The sample of photographs consists of 900 randomly picked images (300 for each mentioned photo-sharing website) geotagged in Central London. Photographs from Flickr and Panoramio are being retrieved by means of service APIs and are copyrighted by their owners. All photographs from Geograph are distributed under CC BY-SA 2.0.

The research has been approved by the University Research Ethics committee, City University London.
