This paper analyzes the routing of agricultural freight from the fields to the elevators. A number of optimization models are built to analyze the effects of truck type restrictions in the truck mix on the overall system cost of delivering from fields to elevators. The models account for both the selection of truck type and load type for deliveries while respecting the load restrictions imposed...

Transport networks vary and change over time. This paper aims to contribute to raising the level of safety in the road transport industry (trucking industry), by assessing the current state of truck accidents, drivers, and regulations which control the land transport in Saudi Arabia. This has been conducted through surveys and field interviews with specialized authorities. Moreover, to evaluate...

A modern text is seldom a stand-alone product consisting merely of writing, but a multimodal body of signs from different meaning-making systems. The multimodal context and the new forms of translation, in which the concept of ‘text’ goes beyond language, have become increasingly relevant in contemporary translation research and practice. In order to study multimodal context and intermodal form...

The concept of flow has become particularly important in logistics and freight distribution. From a simple question of capacity, the issues of timing, frequency and punctuality are now of significant relevance in freight movements since they are part of supply chain management strategies. In particular, transport terminals and freight distribution centers have been the major elements permitting...

The goal of this study was to compare the performance of a chimpanzee and humans on auditory-visual intermodal matching of conspecifics and non-conspecifics. The task consisted of matching vocal samples to facial images of the corresponding vocalizers. We tested the chimpanzee and human subjects with both chimpanzee and human stimuli to assess the involvement of species-specificity in the recog...

Ever since public transit agencies have found their way to the Web, they inform travelers using route planning software made available on their website. These travelers also need to be informed about other modes of transport, for which they have to consult other websites, or for which they have to ask the transit agency’s server maintainer to implement new functionalities. In this demo, we intr...

15. Supplementary Notes Supported by a grant from the U.S. Department of Transportation, University Transportation Centers Program 16. Abstract The objective of this research is to characterize large truck safety levels in Texas on the basis of driver, vehicle, cargo, and carrier traits while controlling for the effects of crash and operating environment conditions. Data to support this investi...

Seaport terminals recognise the need to change current practices in order to improve regional air quality while enhancing their terminals’ competitiveness. One area that terminals can do better at is to improve their yard crane operations and in turn reduce the trucks in-terminal delay. This study examines various container rehandling strategies by the yard cranes with the goal of improving the...

The nonlinear behavior of soils can significantly modify the wavelet radiated from vibrator trucks. In this paper, we describe a field experiment designed to measure the nonlinear response of a natural soil formation in the near-field of a vibrator truck. A 267-kN (30-ton) vibrator truck performed a step-sweep through a set of 201 discrete frequencies from 50-Hz to 10-Hz, which was repeated at ...

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...
