Download or read book Evaluation of Overhead and In Ground Vehicle Detector Technologies for Traffic Flow Measurement written by LA. Klein and published by . This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This report covers the Phase A and B activities of Research Project SPR 627 for the Arizona Department of Transportation (ADOT). Phase C is planned as a separate research activity and is anticipated to begin in the near term, following the completion of Phases A and B. The need for a better valuation program for new traffic detection systems came in part from a lack of confidence in existing detectors, as well as the need for non-intrusive detectors to replace failing embedded inductive loops. The primary objectives of this research were to identify the most promising vehicle detection technologies to meet ADOT needs, to identify candidate test sites, to develop a field test evaluation plan, and to develop and deliver a detailed design of the detection testbed on the selected segment of freeway. The Texas Transportation Institute (TTI) met these objectives through an Internet and literature search, a state-of-the-practice review, a search of relevant new detector systems, and through meetings with the Technical Advisory Committee (TAC). Relying on TAC input, TTI developed first a conceptual design, followed by a detailed design and budget for a proposed test facility located on I-10 in Phoenix just west of the 16th Street interchange. Detectors selected for test in the initial period of 12-plus months during Phase C (and the technology used) are as follows: Wavetronix SS-125 (microwave radar), Sensys Networks (magnetic), Global Traffic Technologies microloops (magnetic) and Autoscope Solo Pro (video imaging). The baseline system selected for providing ground truth data is the Peek ADR-6000 using inductive signatures as its basis of detection. It is anticipated that this Phase C testing will include two summer seasons to expose selected detectors to the extreme heat and related environmental conditions found in the Phoenix. The initial cost of the testbed will include detectors sufficient to ultimately cover eight lanes in the westbound direction (currently seven lanes) and six lanes in the eastbound direction. Besides the detectors, the total cost estimate includes a 12 ft by 12 ft node building, three equipment cabinets, inductive loops for the baseline system, conduit, and boring. The total cost of the facility is estimated to be approximately $566,000.

This book was released on 1997 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the activities and results of a test of non- intrusive traffic detection technologies. Seventeen devices representing eight different technologies were evaluated in varying environmental and traffic conditions. The following technologies were tested: passive infrared, active infrared, magnetic, radar, doppler microwave, pulse ultrasonic, passive acoustic, and video. Testing was done at both freeway and intersection locations. Emphasis was placed on urban traffic conditions and locations that typify temporary counting locations. The evaluation also focused on the ease of system setup and use, general system reliability, and system flexibility.

Download or read book Vehicle Detector Evaluation written by Dan Middleton and published by . This book was released on 2002 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most vehicle detection today relies on inductive loop detectors. However, problems with installation and maintenance of these detectors have necessitated evaluation of alternative detection systems. Replacing loops with better detectors requires a thorough evaluation of the alternatives. This research included examination of the performance characteristics, reliability, and cost of these technologies. The detection technologies included in this study were: video image detection, radar, Doppler microwave, passive acoustic, and a system based on inductive loops. Research results clearly indicate promising non-intrusive alternatives to loops, but their limitations must be understood. This research solicited information from a variety of agencies pertaining to installation and use of non-intrusive technologies and conducted field tests on a high volume freeway to determine their suitability for implementation. Findings indicate that non-intrusive detectors have improved since recent detector research sponsored by the Texas Department of Transportation. Count accuracies of 95% and speed accuracies within 5 mph of true values are common during free-flow conditions. During slower congested flow traffic, all non-intrusive device count accuracies degraded to the range of 70 to 90%, and most speed accuracies worsened as well--differing by 10 to 30 mph from the baseline system.
