摘要：	This research was designed as proof-of-concept study to investigate how Bluetooth data loggers can be used to collect vehicle operational data over traditional vehicle counting methods. The reliability test included mapping areas for five antenna options and their detection reliabilities were investigated. Other tests were conducted to assess the impacts of roadside antenna placement, vehicular speeds and in-vehicle source placement. The feasibility of using data from Bluetooth enabled devices in vehicles as a surrogate for traditional traffic engineering data were investigated for several types of traffic studies. These studies included, urban corridor travel time monitoring, freeway travel time monitoring, origin-destination studies, estimating turning movements at roundabouts, and truck tracking across the state of Kansas. Each of these studies demonstrated how the same technology could be applied to different study objectives. While this technology was found to have enormous potential to collect vehicle operational data, it was not found to be completely stand-alone. An identified weakness of the technology was that it was found to sample around 5 percent of the available traffic. The implication of this was that Bluetooth data were not always available for analysis due to low traffic volumes at some rural locations.
