Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to evaluate low cost weigh-in-motion systems. The three systems evaluated were (1) a capacitance weigh mat system, (2) a bridge weighing system, and (3) a piezoelectric cable sensor system. All three systems have a two-lane capability. An evaluation was made of (1) the quality of the data, (2) the performance of the equipment, (3) the applications of the equipment and its ease ofuse, and (4) the format of the data and its usefulness. Although objective data were used when possible, the majority of the evaluation is subjective. The quality of the data from each of the three systems is about the same. The piezoelectric cable system provides slightly lower quality data than the other two systems. The equipment of the capacitance weigh mat performed well; that of the bridge system was adequate; and there was concern about the durability of the piezoelectric cable system. Because of the tradeoffs between the capacitance weigh mat system and the bridge system, it is difficult to rank them. The piezoelectric cable system's sensors are permanently installed; therefore, it is not as portable as the other two systems. With regard to the format of the data and its usefulness (which are dependent mostly on the software and not the sensors), the capacitance weigh mat system is flexible and provides individual truck records in two formats, the bridge system provides the most comprehensive tables, and the piezoelectric cable system is limited and depends on other software to generate additional tables. Suggestions are made about how to use the systems and how to improve their performance.

Book excerpt: The Minnesota Local Road Research Board, MnDOT, and SRF performed an evaluation of a portable weigh-inmotion (WIM) system at several locations throughout Minnesota. The system was developed at the University of Minnesota-Duluth and offers roadway designers a low-cost method for obtaining vehicle load distribution data across the state's road network. To deploy the system, the weigh pads of the system were temporarily affixed sensors across the roadway lanes. As vehicles passed over the weigh pads, pressure sensors within the pads detected the weight of vehicles and the system recorded the data for later analysis. Traditional methods for travel monitoring generate traffic volume and classification data, but weigh-in-motion systems give designers a more accurate idea of current and projected traffic loading demands. SRF's testing provided implementation refinements that were incorporated into the system. During the two-year deployment process, the portable WIM system was installed under a wide array of environmental conditions to demonstrate the system's capabilities. Data generated by the system was analyzed. The Final Report details system deployment, calibration, and system accuracy.

Download or read book LTBP Program's Literature Review on Weigh-in-motion Systems written by Imad Al-Qadi and published by . This book was released on 2016 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Truck size and weight are regulated using Federal and State legislation and policies to ensure safety and preserve bridge and high infrastructure. Weigh-in-motion (WIM) systems can capture the weight and other defining characteristics of the vehicles actually using the Nation's highways, providing important loading-related data that is essential for evaluating the performance of transportation infrastructure. As part of the Federal Highway Administration's (FHWA) Long-Term Bridge Performance (LTBP) Program's Technical Assistance Contract, a literature review of the state of the practice was performed for WIM systems installed in pavements and on bridges. This literature review focused on the development of WIM systems, concepts for measuring axle loads, the applications of WIM sensors for pavements, and recent advancements in bridge WIM system. This review covers the types, installation, calibration, operations, accuracy, efficiency, effectiveness, and durability of WIM systems, in addition to current Federal and State truck load regulations. This review facilitates selection of the appropriate WIM technology systems for consideration and use to address LTBP Program needs. This literature review serves as a reference document for Pooled Fund Project Number TPF-5(283), The Influence of Vehicular Live Loads on Bridge Performance, which targets the impact of vehicle live loads on bridge component durability.

Download or read book Advanced Weigh-in-motion System for Weighing Vehicles at High Speed written by and published by . This book was released on 1998 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art, Advanced Weigh-In-Motion (WIM) system has been designed, installed, and tested on the west bound side of Interstate I-75/I-40 near the Knox County Weigh Station. The project is a Cooperative Research and Development Agreement (CRADA) between Oak Ridge National Laboratory (ORNL) and International Road Dynamics, Inc. (IRD) sponsored by the Office of Uranium Programs, Facility and Technology Management Division of the Department of Energy under CRADA No. ORNL95-0364. ORNL, IRD, the Federal Highway Administration, the Tennessee Department of Safety and the Tennessee Department of Transportation have developed a National High Speed WIM Test Facility for test and evaluation of high-speed WIM systems. The WIM system under evaluation includes a Single Load Cell WIM scale system supplied and installed by IRD. ORNL developed a stand-alone, custom data acquisition system, which acquires the raw signals from IRD's in-ground single load cell transducers. Under a separate contract with the Federal Highway Administration, ORNL designed and constructed a laboratory scale house for data collection, analysis and algorithm development. An initial advanced weight-determining algorithm has been developed. The new advanced WIM system provides improved accuracy and can reduce overall system variability by up to 30% over the existing high accuracy commercial WIM system.

Download or read book Drivers Assessment of High Speed AVI/WIM System at a Weigh Station in Illinois written by and published by . This book was released on 2000 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study analyzed truck drivers' opinions about application of intelligent transportation systems (ITS) technologies to commercial vehicle operations (CVO). As part of the evaluation of Automatic Vehicle Identification (A VI) and Weigh-In-Motion (WIM) systems at the Williamsville weigh station in Illinois, a survey of the participating truck drivers was conducted. The survey consisted of 37 questions inquiring about the driver's professional background, weigh station experience, and opinions about the AVI/WIM system. The majority of the drivers (86%) had schedules where time was important, and delays greater than 30 minutes were intolerable. For three-quarters of the drivers, time was "critical" or "very important." Eighty four percent of drivers said the AVI/WIM system benefits them by reducing trip delay. !n addition, about 91% of drivers thought the AVI transponder system reduces the hazards of merging and diverging at weigh stations. The hazard level at weigh station entrances and exits were not significantly different than the hazard level at regular exit or entrance ramps. Some of the participating drivers experienced some frustration in using the system because they felt that the system simply did not work for them all the time. Although the drivers generally favored the adoption of the AVI system, slightly less than half were willing to pay up to one dollar. Eighty-eight percent of the drivers advocated the installation of AVI transponder systems at all Illinois weigh stations, and 88% wished to continue using the AVI transponder system.
