GPS tracking

It is obvious that individuals’ spatial knowledge about urban environment is cumulative and comprehensive. Thus for understanding the complexity of one's spatial knowledge we are going to look how NEWCOMERS first exposed to an area learn about the urban environment over time, assuming that they start to learn from the ZERO point.
We consider that individuals’ spatial knowledge evolves over time as a function of activity-travel behaviours. To be able to capture these learning dynamics the best way is to collect data on individuals’ activity-travel patterns during several weeks.

If we want to collect data for several weeks it should not cost too much respondents burden. GPS technology allows collecting accurate spatial and temporal data on travel of vehicles and people for several weeks. In particular, GPS tracers provide information about the route taken, distance covered, time, speed, latitude and longitude. Additional data can be derived from GPS tracers such as visited location, used transport mode, trip duration, departure and arrival times.

Participants of the study carry GPS logger Bluetooth 747 A+ for 12 weeks. When participants travel in the city the GPS tracking data are continuously recorded in GPS logger memory every 3 second (latitude, longitude, speed and time).

We can not track you while you are travelling!
GPS logger records data off-line mode. Even though it can be called a tracking, we can only know the complete route when you download data by using the usb cable and upload a file on the website.

device characteristics
747 A+ logger features an all-in-one, cost-effective portable GPS logging solution. With its on-board memory, it allows you to log your routes by ways of time/ distance/ speed.

- operating time is more than 24 hours on single charge.

- charging time is about 3-4 hours
- semi indoor device that allows also collect data inside buildings
- 125.000 waypoints can be reordered
