Book Description
Most vehicle detection today relies on inductive loop detectors (ILDs). However, problems with installation and maintenance of these detectors have necessitated evaluation of alternative detection systems. Replacing ILDs with better detectors requires a thorough evaluation of the alternatives. This evaluation included examination of the functional quality, reliability, and cost of these technologies as well as development of recommendations for application. Primary detection technologies included in this study are video image detection systems (VIDS), passive infrared, active infrared, passive magnetic, radar, Doppler microwave, passive acoustic, and ILDs. Results of new detector testing clearly indicate promising alternatives to ILDs, but the limitations of these new detectors must also be accepted. Researchers found that some technologies performed quite well while, in some cases, offering features that are more flexible than ILDs. These technologies include VIDS, passive infrared, active infrared, radar, Doppler microwave, and pulse ultrasonic.

Book Description
Under sponsorship from the Federal Railroad Administration (FRA), the Transportation Technology Center, Inc. (TTCI) and the John A. Volpe National Transportation Systems Center (Volpe Center) evaluated five technologies for their ability to detect trains and/or highway vehicles approaching and occupying highway railroad intersections (HRI). TTCI conducted tests on the performance of these technologies during October and November 1999 at the FRA's Transportation Technology Center in Pueblo, Colorado, USA.

Evaluation of Overhead and In-Ground Vehicle Detector Technologies for Traffic Flow Measurement

ISBN:
Category : Automobiles
Languages : en
Pages : 10
Book Description
As part of the U.S. FHWA-sponsored Detection Technology for IVHS program, ultrasonic, microwave radar, infrared laser radar, nonimaging passive infrared, video image processing with visible and infrared spectrum imagery, acoustic array, high sampling rate inductive loop, conventional inductive loop, microloop, and magnetometer detector technologies were evaluated at freeway and surface street arterial sites in Minnesota, Florida, and Arizona. These states were chosen because they exhibited a wide range of climatic conditions. The criteria for selecting the detector evaluation sites included searching for roadways with high traffic density and suitable structures for mounting the overhead detectors. Approximately 5.9 Gbytes of digital and analog vehicle detection and signature data and more than 300 video tapes of the corresponding traffic flow were recorded.
