Bluetooth Sensor Data and Ground Truth Testing of Reported Travel Times

摘要: Travel time information is a valuable statistic in transportation systems. This supports wide body of decision makers, from passengers seeking to minimize trip times authorities who rely on these data for monitoring and planning purposes as well emergency responses. Collecting accurate travel pivotal task. In recent years, the I-95 Corridor Coalition has provided extensive real-time several freeway segments arterials surrounding East Coast under Coalition's Vehicle Probe Project. As partner this collaborative effort, University Maryland been responsible verification validation. process involves comparing reported speeds with observations recorded by Bluetooth sensors evaluate accuracy data. paper discusses comparison method specified project documentation explores some alternative approaches their merits limitations.
