Evaluation of Bluetooth Detectors in Travel Time Estimation

With the current popularity of mobile devices with Bluetooth technology, numerous studies have developed methods to analyze data from such estimate a variety traffic information, as travel time, link speed, and origin–destination estimations. However, few comprehensively determined impact penetration rate on estimated time derived detectors. The objectives this paper were threefold: (1) develop data-processing method based transactional data; (2) determine vehicle speeds detection performance; (3) how affected deviations in time. A 28 km toll section Bangkok, Thailand, was chosen for study. number detectors microwave radar installed collect October 2020. Five steps Based results, during day (50 90 percent) higher than night (20 50 percent). In addition, we found that speed had adverse effects MAC address capability detectors; greater 80 km/h, addresses detected decreased. minimum should be at least 1 percent (or 37 vehicles/h) peak periods 5 49 off-peak period.
