Available in PDF, EPUB and Kindle. Book excerpt: "This report is a deliverable of Task 2 of FHWA's Truck Size and Weight Enforcement Technology Project. The primary project objective was to recommend strategies to encourage the deployment of roadside technologies to improve truck size and weight enforcement in the United States. The objective of Task 2 was to evaluate the state of the practice for using roadside technologies in enforcement activities. Task 2 was supported by an expanded data collection effort designed to capture the "best practices" of states with differing approaches to utilizing technologies. Emphasis was placed on weigh-in-motion (WIM) activities during State site visits and phone interviews. Information about other technologies used by states for enforcement, especially technologies used in association with WIM, also was captured. A list of participating states is included toward the end of the report. Summarized information about their usage of technologies is provided in template format at the end of the report"--Technical report documentation page.

Book excerpt: "The purpose of this Implementation Plan is to recommend strategies to encourage the deployment of roadside technologies to improve truck size and weight enforcement in the United States. The plan includes strategies that State practitioners can use to overcome typical challenges confronting the deployment of virtual weigh stations and other roadside enforcement operations (Section 3.0) and overall program support that FHWA needs to provide to jurisdictions looking to deploy virtual weigh stations and other operations (Section 4.0). The plan is the final deliverable in FHWA's Truck Size and Weight Enforcement Technology project. The goal of the project was to encourage and facilitate states' technology deployments as a means to improve the efficiency and effectiveness of roadside enforcement"--Technical report documentation page.

This book was released on 2010-07-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

This book was released on 2007 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deteriorating roadway conditions have drawn attention to the need to develop an accurate and practical system to control increasing excessive traffic volumes and traffic loads. In practice, traffic volumes often exceed predicted volumes, and truck overloading occurs frequently. Overloading pavements can result in premature deterioration, early or mistimed maintenance activities and eventually higher life cycle costs. As a part of an Intelligent Transportation Systems (ITS), especially in the area of Commercial Vehicle Operations (CVO), Weigh-In-Motion (WIM) has been focused on using state-of-the-art sensing technology to continuously collect vehicle weights, speeds, vehicle classes, and various types of traffic data as vehicles travel over a set of sensors (embedded or portable), without interruption of traffic flows. It is the process of measuring the dynamic tire forces of a moving vehicle and estimating the corresponding tire loads of the static vehicles. WIM technology is imperative for weight enforcement, road network design and management, as well as road safety. The overall purpose of this thesis is to examine the feasibility of using WIM in northern environments such as Canada's. In response, one contribution of the thesis is to develop an economic model for WIM values that include costs due to premature pavement deterioration, benefits of weight enforcement and traffic data collection, benefits of WIM compared to conventional static weigh stations, and benefit-cost ratios of WIM values from road users and non-road users' perspectives. Another contribution is to examine the technical performance (accuracy) of a particular WIM system. Results of field data collection and analysis are presented in this examination. This thesis also compares the advantages and disadvantages of different WIM systems, with respect to cost, accuracy, applicability, reliability, and sensitivity. Future trends and research potential of WIM are also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Weigh stations are the primary weight compliance checkpoints for commercial trucks. In the past several decades, states have used weigh-in-motion (WIM) technology to reduce delay and increase enforcement on overweight vehicles. This study offers a detailed analysis of weigh station systems and presents floating-threshold algorithms to improve the efficiency of WIM equipped weigh stations. This research evaluates weigh station design and operational parameters using queueing theory and found that WIM technology not only enhances the effectiveness and efficiency of weigh station operations but also largely reduces travel delay for trucking companies. The effects of truck demand, truck weight distribution, static scale service time, WIM accuracy, and sorting threshold on weigh station operations have been analyzed. The author shows the importance of transponders in a WIM mainline weigh station operation. The author also proves that the increase of storage spaces within a weigh station may largely increase truck travel delay and does not significantly improve weigh station operations. This research focuses on the development of floating-threshold algorithms. Since the number of trucks, particularly heavy trucks, has increased rapidly in recent decades, many weigh stations cannot meet the demand even when equipped with WIM systems. This problem is complicated by the fact that truck demands, truck weight distribution, and static scale service time vary by time of day and day of week. The author designed floating-threshold algorithms to automatically adapt to high truck demand and the varying of truck demand, truck weight distribution, and static scale service time, over time. When the queue at the weigh station is long, the threshold value is increased so as to avoid the closure of the weigh station while still catching the worst weight limit offenders. When the queue is short, the threshold value is lowered to increase the number of trucks inspected. Both the traditional fixed-threshold strategy and two floating-threshold strategies were modeled and tested using a microscopic simulation model. The results show that floating-threshold strategies are both more effective in weight enforcement and more efficient for heavy traffic flow and high-variance environments. The finding that different floating-threshold strategies have different effects indicates that it is necessary to make a further study on floating-threshold algorithms.
