vibration generated by vehicles during road transport has an important effect on the agricultural products damage process, particularly vegetable and fruit. modulus of elasticity is one of the most important mechanical properties of fruits and its variation can be described as one of the damage criteria during transportation. this research was conducted to evaluate the effects of vibration para...

Logistics cost, the cost of moving feedstock or products, is a key component of the overall cost of recovering energy from biomass. In this study, we calculate for small- and large-project sizes, the relative cost of transportation by truck, rail, ship, and pipeline for three biomass feedstocks, by truck and pipeline for ethanol, and by transmission line for electrical power. Distance fixed cos...

Freight trucks are an important component of the nation s highway traffic. Due to their physical and operational characteristics, they can significantly impact traffic system performance, safety, and the travel experience of non-truck drivers. Methodological gaps exist in the literature on modeling car–truck interactions that do not result in crashes, especially those resulting from non-truck d...

The purpose of the study was to assess the incidence of alcohol and amphetamine use among long-distance truck drivers. There were studied 91 truck drivers at the gas station in Passos, Southeastern Brazil, in November 2005. Data was collected using a questionnaire comprising 19 multiple choice questions. Descriptive statistics, Chi-square test and Cramér's correlation coefficient were used for ...

This research serves to evaluate the potential use of a system developed by the Oregon Department of Transportation (ODOT) for emission estimates. The data collection system developed by ODOT – Truck Road Use Electronics (TRUE) – includes a smart phone application with a Global Positioning System (GPS) device and microprocessor. Previous research with the TRUE data served to demonstrate its use...

Cross-docking is a relatively new logistic strategy which seeks to make economies in transportation, decrease lead time and reduce inventory. The main principle is to unload, sort, consolidate and transfer delivered packages from inbound trucks to outbound trucks, with a minimum of storage or treatment in between. Two key issues associated to this field are the truck scheduling and the shop-flo...

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...
