Optimal Number and Location of Bluetooth Sensors for Travel Time Data Collection in Networks

The importance of accurate prediction of travel time in transportation engineering is irrefutable. Travel time is highly used in traffic management and planning. The accuracy of travel time prediction relies on the accuracy of the travel time data.Various methods are being used in collecting travel time data. Recently, a new method in collecting travel time data is introduced that is called Bluetooth technology. In this method, a number of Bluetooth sensors are deployed over the traffic network that can detect the Bluetooth devices in the vehicles to determine the vehicles' travel time based on matching identification and time of identification of the same Bluetooth device at two consecutive sensors.
