Data Collection of Freeway Travel Time Ground Truth with Bluetooth Sensors

摘要: Accurate travel time information is essential to the effective management of traffic conditions. Traditionally, floating car data have been used as primary source ground truth for measuring quality real-time provided by surveillance systems. This paper introduces Bluetooth sensors a new and means collection freeway time. The concept vehicle identification using signatures estimation along section explained. Issues related error analysis, filtering raw matched data, accuracy resulting compared with are discussed. Data from loop detectors on several segments approximate report average sampling rate sensors. Results show that technology promising method collecting high-quality can be evaluating other sources intellige...
