Safety is a principal focus of government agencies and private-sector organizations concerned with transportation. The Federal Motor Carrier Safety Administration (FMCSA) was established within the Department of Transportation on January 1, 2000, pursuant to the Motor Carrier Safety Improvement Act of 1999. Formerly a part of the Federal Highway Administration, the FMCSA's primary mission is to...

High-performance networking requires attention to operating system support at the device driver level. Existing driver models, such as those of Unix, are not necessarily well-suited to supporting high-speed network interfaces. In fact, current drivers may represent a significant obstacle between applications and the high-speed network adapters they seek to exploit. Yet existing models cannot si...

reviews in many countries indicate that drivers often talk on mobile (cell) phones. studies have been done on possible effects of concurrent mobile phone use on driving performance. previous studies have found that phone talking could impairs performance on simulated or instrumented driving tasks, using such measures as reaction time, following distance, and situational awareness. most of these...

Ridesharing is undoubtedly appealing from a sustainability perspective; however, profit optimization is very important for commercial providers. As such, ridesharing offers a valuable opportunity to garner profit by reducing the number of driver-miles that need to be paid for in order to serve the same set of passengers. In this paper, we study profit optimization for commercial ridesharing ser...

Current commercial tractor guidance systems present to the driver information to perform agricultural tasks in the best way. This information generally includes a treated zones map referenced to the tractor's position. Unlike actual guidance systems where the tractor driver must mentally associate treated zone maps and the plot layout, this paper presents a guidance system that using Augmented ...

We report on methods for widening modulation bandwidths of commercial laser diode drivers Inexpensive commercial laser diode drivers have many important characteristics but unfortunately their modulation bandwidths are often restricted to below kHz Here techniques involving p channel and n channel JFETs have been tested to enhance the modulation bandwidth of drivers suitable for common laser an...

We investigated the phenomenon of sustained health-supportive behaviors among long-haul commercial truck drivers, who belong to an occupational segment with extreme health disparities. With a focus on setting-level factors, this study sought to discover ways in which individuals exhibit resiliency while immersed in endemically obesogenic environments, as well as understand setting-level barrier...
