BACKGROUND Drivers of heavy and tractor-trailer trucks accounted for 56% of all production and nonsupervisory employees in the truck transportation industry in 2011. There are limited data for illness and injury in long-haul truck drivers, which prompted a targeted national survey. METHODS Interviewers collected data during 2010 from 1,670 long-haul truck drivers at 32 truck stops across the ...

In most manufacturing and distribution systems, semi-finished jobs are transferred from one processing facility to another by transporters such as Automated Guided Vehicles, robots and conveyors, and finished jobs are delivered to warehouses or customers by vehicles such as trucks. This paper investigates two-machine flow shop scheduling problems taking transportation into account. The finished...

From a societal perspective, it is desirable for all transportation users to pay their full social (private and external) costs. We estimate four general types of external costs for intercity freight trucking and compare them with the private costs incurred by carriers. Estimated external costs include: accidents (fatalities, injuries, and property damage); emissions (air pollution and greenhou...

Truck and shovel are the most common raw material transportation system used in the cement quarry operations. One of the major challenges associated with the cement quarry operations is the efficient allocation of truck and shovel to the mining faces. In order to minimize the truck and shovel operating cost, subject to quantity and quality constraints, the mixed integer linear programing (MILP)...

There are over 3 million truck drivers employed in the commercial transportation and material moving occupations, one of the largest occupational groups in the United States. Workers in this large and growing occupational segment are at risk for a range of occupational health-induced conditions, including mental health and psychiatric disorders due to high occupational stress, low access and us...

It is often very challenging to plan expedient and cost-effective operations for service trucks under network design constraints, particularly on congested urban roadways. Hence, it is beneficial to simultaneously account for truck facility location design and network expansion decisions to mitigate the additional congestion caused by trucks and facilitate their routing. This paper develops an ...

Once known to be used exclusively in military domain, unmanned aerial vehicles (drones) have stepped up to become a part of new logistic method in commercial sector called "last-mile delivery". In this novel approach, small unmanned aerial vehicles (UAV), also known as drones, are deployed alongside with trucks to deliver goods to customers in order to improve the service quality or reduce the ...

One opportunity to manage the increase of freight transportation and to optimize utilization of motorway capacities is the concept of truck platoons. With the aid of Advanced Driver Assistance Systems, trucks are electronically coupled keeping very short gaps (approx. 10 meters) to form truck platoons on motorways. This contributes to optimisation of traffic flow and reduction of fuel consumpti...

Improving motor carrier and highway safety is a primary focus of many transportation agencies in Canada and the U.S. With the decreased building of new infrastructure, and the rapid growth of trucking activity in the two countries, it is important to develop innovative ways to improve highway safety as it relates to commercial vehicles. Due to the nature of trucking in the Canadian Prairie regi...
