CONCLUSIONS & FUTURE SCOPE
In our opinion GPS-tracking technology can contribute to traditional
mapping, analysis and collection techniques. GPStracking
is a complementary method, providing more accurate
and reliable information about activity patterns of humans. Nevertheless, there are also some limitations: collection, processing
and the significance of results.
6.1 Collection
The way of distributing and returning the GPS devices is time
consuming and risky: will all devices be returned? How is a representative
user group selected? A good point is that the collection
of data is during a fixed timespan: all data is collected at
the same dates during the same conditions. The experiment is
fixed in place and time. Another advantage is the easy collection
of (essential) background information.
6.2 Processing
At the moment retrieving and validating the tracks is a time
consuming part of the processing. This part can be optimized by
developing tools for automatically classifying, cleaning and
splitting of tracks and for recognizing stops and destinations.
Manual work has to be reduced to a minimum.
6.3 Results
The sample of participants has to be taken into account in relation to the whole population. The main question is how much
data is required to produce reliable results. By carrying out research
from one or two access points, or from a minimal number
of households in a district, street or building, the value of
the outcomes is relatively low in respect to the context. To produce
more significant results, especially in the case of sub sampling,
larger datasets are required. Therefor, processing of the
data has to be optimized, and developing new ways of collecting
are essential.
