This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigates the feasibility of using a commercially available portable weigh-in-motion (WIM) system to improve the spatial representation of axle load data from trucks operating on secondary highways. The research evaluated the validity of axle load data collected from three on-road installations next to comparison load data sources, as well as considering the validity of raw and post-processed data. Analysis revealed that portable WIM data cannot achieve the accuracy standard required of ASTM E1318 type II WIM data, but proper installation, calibration, and post-processing can allow portable WIM to have 95% of loads within +/-36% of comparison loads for GVW, within +/-57% for tandem axles, within +/-87% for tridem axles, and within +/-63% for individual axles. Additionally, aggregation and post-processing of the data can allow selected vehicle statistics, such as fully loaded vehicles or GVW distributions, to achieve higher accuracies, potentially allowing for various indirect applications of the data.

Available in PDF, EPUB and Kindle. Book excerpt: Minnesota Department of Transportation (Mn/DOT) needs improved traffic monitoring tools to optimally allocate road maintenance and improvement resources. In particular, the department needs a method of including vehicle and axle weights with portable traffic logging equipment. The cost of existing Weigh-in-Motion (WIM) equipment prevents widespread use in locations where only temporary monitoring is needed. This project was a survey of the suppliers of portable WIM systems, allowing a few systems to be moved between locations of interest. There were four candidate systems found and studied, of which two are recommended for further evaluation. Both systems appear to meet the needs Mn/DOT established and local testing will allow a final decision on their suitability.

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.

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.
