Download or read book Verification Refinement and Applicability of Long term Pavement Performance Vehicle Classification Rules written by Mark E. Hallenbeck and published by . This book was released on 2014 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Long-Term Pavement Performance (LTPP) project has developed and deployed a set of rules for converting axle spacing and weight data into estimates of a vehicle's classification. These rules are being used at Transportation Pooled Fund Study (TPF) weigh-in-motion (WIM) sites across the country. This report examines the performance of those rules and the implications of their use for the development and application of default values for use within the Mechanistic-Empirical Pavement Design Guide. The report is divided into three parts. In part I, the report examines 1) how the LTPP rules differ from classification rules used by many States, 2) the performance of the LTPP rules in terms of their accuracy across truck types and at different LTPP WIM sites across the country, and 3) the size of the error that can be introduced into the estimation of traffic loading inputs for pavement design when load spectra developed from the LTPP TPF sites using these rules are combined with truck volume data collected using State-specific classification rule sets. Part II of this report examines the sensitivity of the pavement design models to the errors introduced by the use of these traffic loading inputs. Based on the results of these sensitivity tests, recommendations are made about the use of load spectra computed using Specific Pavement Studies TPF WIM data. Part III of this report describes minor changes to the LTPP classification rules recommended to improve their performance. Finally, the results of field tests of the recommended revised classification rules are presented.

Download or read book Energy Efficient and Semi automated Truck Platooning written by Alexander Schirrer and published by Springer Nature. This book was released on 2022-05-27 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents research and evaluation results of the Austrian flagship project “Connecting Austria,” illustrating the wide range of research needs and questions that arise when semi-automated truck platooning is deployed in Austria. The work presented is introduced in the context of work in similar research areas around the world. This interdisciplinary research effort considers aspects of engineering, road-vehicle and infrastructure technologies, traffic management and optimization, traffic safety, and psychology, as well as potential economic effects. The book’s broad perspective means that readers interested in current and state-of-the-art methods and techniques for the realization of semi-automated driving and with either an engineering background or with a less technical background gain a comprehensive picture of this important subject. The contributors address many questions such as: Which maneuvers does a platoon typically have to carry out, and how? How can platoons be integrated seamlessly in the traffic flow without becoming an obstacle to individual road users? What trade-offs between system information (sensors, communication effort, etc.) and efficiency are realistic? How can intersections be passed by a platoon in an intelligent fashion? Consideration of diverse disciplines and highlighting their meaning for semi-automated truck platooning, together with the highlighting of necessary research and evaluation patterns to address such a broad task scientifically, makes Energy-Efficient and Semi-automated Truck Platooning a unique contribution with methods that can be extended and adapted beyond the geographical area of the research reported.
Download or read book The Palgrave Handbook of the Anthropology of Technology written by Maja Hojer Bruun and published by Springer Nature. This book was released on 2022-03-23 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Handbook offers an overview of the thriving and diverse field of anthropological studies of technology. It features 39 original chapters, each reviewing the state of the art of current research and enlivening the field of study through ethnographic analysis of human-technology interfaces, forms of social organisation, technological practices and/or systems of belief and meaning in different parts of the world. The Handbook is organised around some of the most important characteristics of anthropological studies of technology today: the diverse knowledge practices that technologies involve and on which they depend; the communities, collectives, and categories that emerge around technologies; anthropology’s contribution to proliferating debates on ethics, values, and morality in relation to technology; and infrastructures that highlight how all technologies are embedded in broader political economies and socio-historical processes that shape and often reinforce inequality and discrimination while also generating diversity. All chapters share a commitment to human experiences, embodiments, practices, and materialities in the daily lives of those people and institutions involved in the development, manufacturing, deployment, and/or use of particular technologies. Chapters 11 and 31 are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Download or read book Adaptive Video based Vehicle Classification Technique for Monitoring Traffic written by and published by . This book was released on 2015 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a methodology for extracting two vehicle features, vehicle length and number of axles in order to classify the vehicles from video, based on Federal Highway Administration's (FHWA's) recommended vehicle classification scheme. There are two stages regarding this classification. The first stage is the general classification that basically classifies vehicles into 4 categories or bins based on the vehicle length (i.e., 4-Bin length-based vehicle classification). The second stage is the axle-based group classification that classifies vehicles in more detailed classes of vehicles such as car, van, buses, based on the number of axles. The Rapid Video-based Vehicle Identification System (RVIS) model is developed based on image processing technique to enable identifying the number of vehicle axles. Also, it is capable of tackling group classification of vehicles that are defined by axles and vehicle length based on the FHWA's vehicle classification scheme and standard lengths of 13 categorized vehicles. The RVIS model is tested with sample video data obtained on a segment of I-275 in the Cincinnati area, Ohio. The evaluation result shows a better 4-Bin length-based classification than the axle-based group classification. There may be two reasons. First, when a vehicle gets misclassified in 4-Bin classification, it will definitely be misclassified in axle-based group classification. The error of the 4-Bin classification will propagate to the axle-based group classification. Second, there may be some noises in the process of finding the tires and number of tires. The project result provides solid basis for integrating the RVIS that is particularly applicable to light traffic condition and the Vehicle Video-Capture Data Collector (VEVID), a semi-automatic tool to be particularly applicable to heavy traffic conditions, into a "hybrid" system in the future. Detailed framework and operation scheme for such an integration effort is provided in the project report.
