The Aalborg GPS Park survey


In this project, visitors of four public parks were followed by GPS in Aalborg, DK.


"Human activities in physical and virtual spaces are the main and significant dynamics of future diverse urban human life. We analyze these human behaviours and activities in physical and virtual environments in space and time and use a cross-disciplinary research approach which will allow a broad discussion of relations and dynamics between humans, spaces, and flows. A considerably part of the data we produce is based on GPS based surveys. Using our surveys it is possible to ask location based and activity based and/or time based questions in real time. Questions like, where are we? What are we doing and for how long time? And why are we doing what we do?" The puprose of the GPS Park survey was primarily to gain experiences with and develop a framework for larger scale data collection using GPS technology and specific hardware. The survey was carried out in four parks in Aalborg in August 2007 and involved 4,462 park visitors. Each park survey consisted of two separate survey parts: a GPS tracking of respondents in the park and a questionnaire survey of respondents visting the park. The GPS Park survey was carried out in Molleparken on Wednesday 8 August and Saturday 11 August 2007- both days from 06.00 to 22.00. In Soheltens Have the survey was carried out on Thursday 16 August and Saturday 18 August 2007- both days from 07.00 to 19.00. In Skanseparken the survey was conducted on Wednesday 22 August and Saturday 25 August 2007 - both days from 07.00 tot 19.00 and in Kildeparken on Wednesday 29 August 2007 from 07.00 to 19.00." (H. Hovgesen, P. Bro, N. Tradisauskas, T. Sick Nielsen, 2009)

Position: position of the respondents was carried out by a map, based on dot information with regard to the latest location before entering the park.
Density: The density of the respondents latest location was combined in a map, based on a calculation of kernel density of one cell dimension of 1x1 and a search radius of 400m.
Accumulated time usage: The time usage in the chosen parts of the park spread out over 5x5 grid cells. The height and the colour indicate the difference in use of time. The higher the column and the darker the red, the more time was spent.

"The general impression from all four parks was that most respondents spent most of their time in the parks on the paths. This particulary applies to Kildeparken. However, some respondents spent a lot of time at certain locations outside the pathways. The majority of respondents who remained outside the 'traffic areas' are mainly found in some sort of 'activity area' such as a children's playground, a tennis court or a fountain surrounded by benches while only a small number of respondents spent a prolonged period of time on the lawn" (Ostermann&Timpf, 2007)
