Project drive test – comparison of five Personal Navigation Devices (PND)

Kurzfassung

This document describes the results of a measurement campaign, where five different PND’s had been compared. The comparison looked for the ability of the PND’s to compute and guide a driver on the fastest path to his or her destination. The basic performance metric which had been used to compare the five PND’s is the relative travel time gain: for each valid trip performed, there was one PND which performed worst (the vehicle guided by this PND had the longest travel time). The difference between the travel time of the worst and the PND currently looked at is the (raw) travel time gain of this PND.
