Travel time of vehicles on a highway is usually estimated from the data collected by loop detectors installed in the highway's pavement. Recently, other technologies, such as cell phone tracking, license plate matching, automatic vehicle identifications (AVI) and probe vehicles that communicate their location via global positioning system (GPS), are employed. This paper presents a methodology for evaluating the data collection technologies in estimating travel time. The methodology was applied to a case study of I-287 in northern New Jersey. The travel time estimates were done using the data collected by TRANSMIT readers, Bluetooth sensors, and INRIX against the “ground truth” travel time of probe vehicles. The accuracy of travel time and speed estimated by various technologies is assessed.
