Abstract
A method to estimate the time of vehicles traveling in roads is presented using Bluetooth sensors. The unique Bluetooth device address of Bluetooth-enabled device inside vehicle can be monitored by some spatially separated Bluetooth sensors. Correspondingly, the travel time can be calculated by the collecting data of these sensors. The reliability and accuracy of our proposed method are demonstrated using field testing data that were collected in an 1863 m long segment of Jiangnan Road in Hangzhou. The experimental results show the consistent detection with the manual recording reference data when the distance between a pair of sensors is bigger than the value of two times of the one by dividing the identification radius of sensor by the system error.
