UrbanDiary Comparison Study


The UrbanDiary project lay dormant for a while after its write up in the CASA working paper 151. However it is back on track with a new set of participants currently tracking their every move. The biggest problem to overcome was the equipment, we simply did not have the recourses to keep it going on a larger scale. Throughout there were two GPS devices in use, but now we have again expanded and twelve GPS loggers are currently used simultaneously.

The area of study this time is not London. The idea is to set up a comparison between two locations. Currently the tracking location is the wider region around and of course in the city of Basel, Switzerland. Earlier posts on Basel can be found HERE and HERE.

It is a region of about 1'000'000 people The tourism office even puts it to 3.5m) and in this sense small compared to London, but in the Swiss context this is rather big. Basel-Stadt (the city of Basle) is the third largest city in Switzerland with 165'000 inhabitants.

Image taken from TEB / The Basel region with green space (unbuilt land), urbanised land (grey) and water (blue). In dark grey is shown the urbanised land until 1960 and in light grey the urbanised land until the year 2000.

Basel is located right at the border to Germany and France. The region therefore covers all three countries. This is represented in the TEB, the 'Trinationalen Eurodistrict Basel' (the Three National Euro (not sure what Euro stands for) District Basel). This planing group is working across the borders and is put together from representatives of all three countries. For Basel as the main regional centre these connection sare very important as is the city for the region. In this sense the simbiosis of the different elements (culturally, politically and practical) will be an interesting aspect of the study in terms of spatial analysis.

The mix of participants is again, as was the London sample, a mixed group. It is put together of different age groups, interests and occupations. It will probably not be exactly the same mix, but similar. The idea is to also get some twenty participants in total to have a comparable amount of data.

The data is collected and stored locally on the device and it wil take a while untile we can download the new data and start analys and visualise. So for now this project has to run for about a month until the first data samples will be available. However I do have some very few days of sample tracks that will give an idea of the travel patterns that can be expected in this new location.

THe large C shape in the centre corresponds with the shape of the river in the main urban area in the TEB overview above.

Are you using the Garmin 405 for this group as well? How often do they update you with trace postings?

I wish I had twelve 405s to do this. The data will be saved on the device locally and I will have to download it manually every few weeks. The storage is quite large.
