In 1999, National Highway Traffic Safety Administration (NHTSA) researchers theorized that substantial improvements could be made in the braking performance of medium and heavy trucks. Therefore, NHTSA initiated a multi-year research program to learn what improvements in stopping performance could be achieved using advanced, but currently available, brake technology for medium and heavy trucks....

Purpose. The most common type of technological transport in open pit mines is automobile, which uses dump trucks with a capacity 45 to 220 tons. rock mass transportation volume the use motor at iron ore industry more than 350 million tons per year, or 27% total industry. Most Ukraine’s high-capacity are forced work conditions intensification mining operations, constant deepening and complicatio...

Recent U.S. Environmental Protection Agency emissions regulations have resulted in lower emissions of particulate matter and oxides of nitrogen from heavy-duty diesel trucks. To accelerate fleet turnover the State of California in 2008 along with the Ports of Los Angeles and Long Beach (San Pedro Bay Ports) in 2006 passed regulations establishing timelines forcing the retirement of older diese...

Survey data on large trucks involved in fatal accidents and on the travel of large trucks provide estimates of fatal accident involvement rates by driver age. The analysis is focused on the implications of lowering the minimum age for drivers of commercial trucks operating interstate from 21 to 19 years. Fatal accident involvement rates for drivers of large trucks are found to increase with dec...

In container terminal operations, the delay of containers delivery is a common problem that confronts both the terminal operator and the customers represented by the trucking companies. One source of this delay is due to the long waiting time of the transporting trucks at container terminals (CTs). In this paper, the problem of long turn time for external trucks is studied. An extensive review ...

Gasand particle-phase pollutants were measured separately for (a) light-duty (LD) vehicles and (b) medium-duty (MD) and heavy-duty (HD) diesel trucks. Measurements were made during summer 2006 at the Caldecott Tunnel in the San Francisco Bay area as part of a continuing campaign to track changes in vehicle emissions over time. When normalized to fuel consumption, NOx emission factors were found...

A wide variety of heavy vehicle types—including single-unit trucks, combination trucks with one, two, or three trailers, and buses—operate on U.S. highways. These heavy vehicle types each have unique physical and performance characteristics that interact with highway features. This chapter summarizes the physical and performance characteristics of heavy vehicles. The issues addressed in this ch...

As the flagship of Hutchison Port Holdings (HPH), Hongkong International Terminals (HIT) is the busiest container terminal on the planet. HIT receives over 10,000 trucks and 15 vessels a day, about six million twenty-foot equivalent units (TEUs) a year. HIT makes hundreds of operational decisions a minute. HIT’s terminal management system, the productivity plus program (3P), optimizes resources...

In a container trucking company, the construction of a schedule of reservations is to assign to each reservation, optimally, one or more container while meeting the deadlines proposed by the customers, the employment regulations and the availability of trucks. In this paper, we deal this problem of assignment which consists of minimizing the total distance traveled by trucks while satisfying al...
