Abstract

There are many challenges in testing data collection accuracy and latency of floating car technologies, and especially cellular based. Using floating test vehicle as reference, for example, will provide good results even if the detection system does not detect slowdowns at all, when averaged for a long time. Cellint's results, which were validated by third parties, are described in this article. Slowdown detection latency is the most important factor, which should be benchmarked against road sensors only during times of speed fluctuations. A few minutes latency in detecting slowdowns and 10% difference in travel time can be achieved by these systems. For the covering abstract see ITRD E134653.
