Title: Validation of Travel Times based on Cellular Floating Vehicle Data
Abstract: Acquiring accurate traffic information on a roadway network is a constantly evolving discipline, employing all kinds of technologies world-wide. In this paper, we take a closer look at a method for deriving travel times based on the information from mobile cell phones. The technique is based on the patented Cellular Floating Vehicle Data (CFVD) technology of ITIS Holdings, whereby cell phones exchange information with stationary antenna posts. This paper reports on results of a validation effort that assesses the usability of the CFVD technology for extracting travel times and traffic conditions, implemented in the region of Antwerp, Belgium with a study area covering all motorways and the major regional and urban roads in the neighbourhood of the city. To this end, we compared the results of the CFVD technology with different other independent traffic sources: data obtained by single inductive loop detectors embedded in the roads, and observations derived by test drives with a GPS-equipped probe vehicle. Our results indicate that the CFVD technology has a very good performance on motorways, is able to capture the large variations in travel times on roads containing intersections, and easily outperforms the standard road-based detectors.
