Tracking and Interviewing Individuals With GPS and GSM Technology on Mobile Electronic Devices
Overview More and more transportation surveys use GPS technology, while GSM technology is used only in a few research projects. GPS technology provides very accurate data but is not always applicable due to technical restrictions like open view to the satellites which is especially crucial when participants use public transport. GSM is virtually always available but its spatial accuracy is less accurate. The combination of both technologies is promising more complete spatial data (origin, route, destination) when tracking individual's routes. This paper explains how either the parallel use of GPS and GSM tracking technology at the same time or the use of GSM tracking technology only, combined with a historic GPS/GSM tracking database can produce reliable tracking results.
