INITIAL BLUETOOTH PROBE VEHICLE PENETRATION RATE ANALYSIS: A CASE STUDY IN THE CITY OF ZAGREB

The most of Intelligent Transport System applications rely on various traffic flowdata collection technologies. Bluetooth is widely used standard for wireless short-range communication. It is not dedicated for traffic data collection, but Bluetooth devices located in vehicles make them act as detectable probes in traffic flow. That allows collecting of very desirable traffic flow data such as travel times and constructing origin-destination matrices. The Bluetooth probe penetration rate analysis is the first and necessary step for assessment of Bluetooth as traffic flow data collection technology in the area of interest. In this paper we bring field measurement, raw data processing, and filtering with robust filters for detecting outliers in vehicle detection using Bluetooth signal as a marker. In accordance with the reviewed literature, obtained results show that Bluetooth probe penetration rate in the City of Zagreb is sufficient for some ITS applications, and it is stable throughout the week.
