Monitoring a Freeway Network in Real Time Using Single-Loop Detectors

The present-day ability to monitor traffic and convey traffic information in real-time has been dramatically advanced by the widespread adoption of automated traffic sensors, the increase of computer processing power, and the evolution and growth of the global Internet. Most of the current traffic information systems primarily provide general traffic flow information. This article describes the design and implementation of a traffic monitoring and information system recently developed at the University of Washington that visually conveys speed and vehicle classification information, obtained by processing real-time single-loop measurements, to the general public via the computer. This system can provide vehicle classification data, such as truck volumes, that can and should be key inputs for good transportation planning, freight mobility analysis, roadway geometric and structural design and traffic control and operation. The authors conclude that the development of this system makes real-time monitoring of truck volume data on a freeway network possible.
