ID: 321 It is believed that increasing truck volumes contribute to traffic congestion, pavement deterioration and crashes due to differences in the physical and operational characteristics of trucks and passenger cars. A 2002 US DOT report showed that the number of crashes involving commercial trucks had increased by 40.3% over the last two decades. Based on Insurance Institute for Highway Safe...

Effects of intermodal attention AND of cross-modal links in spatial attention on visual and auditory event-related potentials (ERPs) were investigated in two experiments where participants had to attend to one stimulus modality (audition or vision) to respond to infrequently presented targets whenever these were presented at a relevant location (indicated by a cue). The ERP effects of intermoda...

In this paper, some results concerning the k-truck problem are produced. First, the algorithms and their complexity concerning the off-line k-truck problem are discussed. Following that, a lower bound of competitive ratio for the on-line k-truck problem is given. Based on the Position Maintaining Strategy (PMS), we get some new results which are slightly better than those of [1] for general cas...

Capacity uncertainty is a common issue in the transportation planning field. However, few studies discuss the intermodal routing problem with service capacity uncertainty. Based on our previous study on the intermodal routing under deterministic capacity consideration, we systematically explore how service capacity uncertainty influences the intermodal routing decision. First of all, we adopt t...

Inland transportation of containers contributes significantly to the total cost container intermodal transportation. For this reason, it has received a lot attention in last few decades. While there are many reports attempts solve problem out there, variants considered all simpler than form addressed paper. Here, we consider where pick-up and delivery orders, empty loaded containers, Discharge ...

BACKGROUND HIV prevention programmes for truck drivers form part of the HIV control efforts, but systematic data on the outputs and cost of providing such services in India are not readily available for further planning and use of resources. METHODS Detailed cost and output data were collected from written records and interviews for 2005-2006 fiscal year using standardized methods at six samp...

The 21st century will see a renewed focus on intermodal freight transportation driven by the changing requirements of global supply chains. Each of the transportation modes (air, inland water, ocean, pipeline, rail, and road) has gone through technological evolution and has functioned separately under a modally based regulatory structure for most of the 20th century. With the development of con...

The present study focuses on the question of whether inter- and intramodal forms of attention are reflected in activation of the same or different brain areas. ERPs were recorded while subjects were presented a random sequence of visual and auditory stimuli. They were instructed to attend to nonspatial attributes of either auditory or visual stimuli and to detect occasional target stimuli withi...
