Abstract :
The reliability of the navigation output of an intelligent transportation system (ITS) is studied in detail in this paper. The system under consideration consists of a GPS receiver, a rate gyro as well as a digital map. Map-matching is performed during system integration and errors from the digital map as well as from the GPS and gyro sensors are studied. The minimum detectable bias for the GPS only system is analyzed. The ability of gyro and digital map to improve the reliability is evaluated. Two test data sets, one in an open area while the other in downtown, are used to illustrate the reliability of the integrated system
