Available in PDF, EPUB and Kindle. Book excerpt: This study focused on developing and analyzing various concepts of operation that would link advanced onboard vehicle and driver monitoring technologies with a means of wirelessly communicating such information to local enforcement agencies in order to improve the quality, efficiency, and effectiveness of the North American Standard (NAS) roadside safety inspection program. The hypothesis which prompted the study was that wireless inspection technology could be widely deployed at both traditional and virtual inspection sites to dramatically increase the number of inspections completed, and to improve pre-screening of vehicles for more detailed manual inspections. Information about the condition of the vehicle and the driver would be assembled electronically in a standard safety data message set and then transmitted to the infrastructure, using dedicated short-range communication (DSRC) technology. Concepts developed were differentiated from current electronic pre-screening programs in that real-time information about the vehicle and driver would be conveyed. Based on a review of inspection and crash data, as well as discussions with the commercial motor vehicle (CMV) industry, the high-level requirements for a wireless commercial vehicle inspection concept should focus on gathering data related to the brakes, tires, lighting systems, Hours-of-Service (HOS), commercial drivers license (CDL) information, carrier identity, and vehicle identification number (VIN). All of this information already exists on the vehicle (via discrete sensor systems or electronic control modules) and, by using conventional technologies, could be electronically linked to the serial databus for subsequent transmission to the infrastructure access points. This information, when combined with the historical information already available on carriers and drivers accessible via Motor Carrier Management Information System (MCMIS) and/or State CMV databaseswould provide the enforcement community with a very powerful decision support tool for screening vehicles and/or implementing virtual, automated, wireless inspection sites.

Download or read book Improving Motor Carrier Safety Measurement written by National Academies of Sciences, Engineering, and Medicine. This book was released on 2017-10-01. Available in PDF, EPUB and Kindle. Book excerpt: Every year roughly 100,000 fatal and injury crashes occur in the United States involving large trucks and buses. The Federal Motor Carrier Safety Administration (FMCSA) in the U.S. Department of Transportation works to reduce crashes, injuries, and fatalities involving large trucks and buses. FMCSA uses information that is collected on the frequency of approximately 900 different violations of safety regulations discovered during (mainly) roadside inspections to assess motor carriers' compliance with Federal Motor Carrier Safety Regulations, as well as to evaluate their compliance in comparison with their peers. Through use of this information, FMCSA's Safety Measurement System (SMS) identifies carriers to receive its available interventions in order to reduce the risk of crashes across all carriers. Improving Motor Carrier Safety Measurement examines the effectiveness of the use of the percentile ranks produced by SMS for identifying high-risk carriers, and if not, what alternatives might be preferred. In addition, this report evaluates the accuracy and sufficiency of the data used by SMS, to assess whether other approaches to identifying unsafe carriers would identify high-risk carriers more effectively, and to reflect on how members of the public use the SMS and what effect making the SMS information public has had on reducing crashes.

Download or read book Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles written by National Research Council. This book was released on 2010-07-30. 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.
