Handover location accuracy for travel time estimation in GSM and UMTS

In this paper, field measurements from the GSM and 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 handovers can be predicted correctly, a conclusion from the experiments is that the handover location accuracy in both GSM and UMTS will be sufficient to estimate useful travel times, also in urban environments.
