Handover location accuracy for travel time estimation in GSM and UMTS

In this paper, field measurements from the GSMand UMTS networks are analysed in a road traffic information context. The measurements indicate a potentially large improvement using UMTS signalling data compared to GSM. These improvements can be used to generate traffic information with higher quality and extend the geographic usage area for these kinds of systems. Assuming that non-vehicle terminals can be filtered out and that handoverscan be predicted correctly, a conclusion from the experiments is that the handoverlocation accuracy in both GSMand UMTS will be sufficient to estimate useful travel times, also in urban environments.
