Book Synopsis WIM Data Collection and Analysis by : Jerry G. Pigman
Download or read book WIM Data Collection and Analysis written by Jerry G. Pigman and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to review and analyze current procedures in order to implement a process for collecting and analyzing weigh-in-motion (WIM) data to insure an adequate and accurate representation of weights of vehicles using Kentucky's roadways. A literature review of WIM data collection equipment, practices and procedures indicated that a range of options are available and used by other agencies. Piezoelectric cable detection systems were most frequently used and provided adequate accuracy, if attention is given to monitoring and calibration. An overall assessment of Kentucky's WIM data collection program resulted in recommendations for: 1) increased use of cell modems for more efficient data download, 2) attention to quality control of data with a routine program of polling sites and monitoring consistency of front-axle weights, 3) expansion of WIM data collection program to capture a wider range of functional class coverage of truck traffic, 4) attention to weight data collection on coal-hauling routes, 5) consideration of using static weigh station data to increase coverage of truck weight monitoring, 6) initiation of a data collection plan to capture sufficient data to develop length-based classification factors, 7) continued review and evaluation of new software that has the capability of increasing the efficiency and accuracy of WIM data processing, and 8) evaluation of the cost-effectiveness of expanded and accurate WIM data collection and the impact on pavement thickness designs.

Book Synopsis Traffic Data Collection and Analysis by : Alexander French
Download or read book Traffic Data Collection and Analysis written by Alexander French and published by Transportation Research Board National Research. This book was released on 1986 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to traffic engineers, highway planners, and others concerned with the collection of traffic data for traffic engineering studies, for long-range planning, and for evaluation of traffic law enforcement. Information is presented on current practice in traffic data collection and analysis. Although types of highway traffic data collected over the past 50 years have not changed significantly, the quantities, analysis procedure, and presentations of these data have changed as a result of changing policies, operational concerns, and capabilities resulting from new technologies. This report of the Transportation Research Board describes the technology (both hardware and software) that is being used for traffic data collection, and discusses technological advances that have not yet been applied to the acquisition and presentation of traffic data.

Book Synopsis Using WIM Systems and Tube Counters to Collect and Generate ME Traffic Data for Pavement Design and Analysis by : Lubinda F. Walubita
Download or read book Using WIM Systems and Tube Counters to Collect and Generate ME Traffic Data for Pavement Design and Analysis written by Lubinda F. Walubita and published by . This book was released on 2019 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Axle load spectra data, typically from permanent weigh-in-motion (WIM) stations, constitute the primary mechanistic-empirical (ME) traffic data input for accurate and optimal pavement design and analysis. However, due to the limited number of available permanent WIM stations (mostly located on interstate highways), most ME pavement designs rely on antiquated estimates, even for the 18-kip equivalent single axle loads (ESALs) that often result in un-optimized and costly designs and/or poor-performing pavement structures with increased maintenance costs or high construction costs due to overdesigning -- with high overall life-cycle costs. As a means to address these challenges, this study was initiated, among others, to (a) review the current state-of-the-art methodologies used for estimating ME traffic data inputs, (b) develop clustering algorithms for estimating site-specific ME traffic data, (c) explore the portable WIM as a supplement to the permanent WIM station data, and (d) develop and manage a Microsoft Access ME traffic data storage system (T-DSS). The scope of work included traffic data collection from numerous WIM stations and development of traffic data analysis macros and clustering algorithms. Key findings from the study indicated the following: (a) portable WIM is a cost-effective supplement for site-specific traffic data collection -- with proper installation and calibration, quality traffic data with an accuracy of up to 90% is attainable; (b) the developed WIM data analysis macros are satisfactorily able to compute and generate ME traffic inputs for both flexible and rigid (concrete) pavements; and (c) the developed clustering algorithms and macros constitute an ideal and rapid methodology for predicting and estimating ME traffic data inputs. Key recommendations are continued portable WIM data collection, particularly in West Texas and on farm-to-market (FM) roads, for population of the T-DSS and improved prediction accuracy of the clustering algorithms.
Download or read book Weigh in Motion Data Analysis written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At hundreds of Weigh in Motion (WIM) stations, State Departments of Transportation collect traffic data every year to support pavement design, to enforce weight restrictions on highways and bridges, and to provide planning data for highway improvements. Reliable WIM data is particularly important to support the procedures in the FHWA Mechanistic Empirical Pavement Design Guide (MEPDG). The purpose of the research is to identify and resolve four related but relatively stand-alone problems associated with WIM data collected by NCDOT. Quality Control: After the NCDOT collects WIM data and converts it from proprietary vendor format to an ASCII text format, the quality of the data must be checked. During the quality control (QC) procedures, tests identify incomplete datasets, out of range values for individual vehicle classes, and other possible data problems. Vehicle class and weight checks generate 0.97% and 6.42% anomalies, respectively thus confirming that NCDOT equipment captured reliable WIM measurements. NC Urban and Rural Truck Traffic Profiles: Knowing the type of traffic by vehicle class by highway functional classification is critical to designing, maintaining and paying for North Carolina highway pavements. Thus, GVW plots by vehicle class and highway functional class are very important. The results indicate that in general, the class 5 and 9 GVW plots for all categories of WIM stations show expected trends. These results may be used by highway planners and pavement designers to quickly determine typical truck traffic profiles in the various NC regions and provide insight into NC truck transportation flows. NC vs. University Of Arkansas WIM QC Analysis: Most highway agencies have the data collection and design groups in different units. While a single software solution is not practical, it is recommended to perform two separate processes where the output of data QC meets the needs and standards of the design process. A comparative analysis between the QC meth.

Download or read book A Synthesis of Safety Implications of Oversize/overweight Commercial Vehicles written by and published by AASHTO. This book was released on 2009 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this report is to identify known relationships between commercial vehicle safety and crash causation factors and to prepare a synthesis of safety implications of oversize/overweight (OS/OW) commercial vehicles. This information can be used to support commercial vehicle enforcement and permitting practices and justify expenditures and investments on size and weight enforcement to enhance safety. In producing this report, insight was gained into the impacts of truck size and weight (TSW) regulations through three case studies. The state of practice in estimating large truck crash rates is complicated because of the many configurations and the wide range of possible weights for any particular configuration. This report highlights four primary findings regarding the contributions of OS/OW to commercial vehicle crashes found by its researchers.
