The issue of truck accidents on urban freeways is a vital concern for both traffic managers and the general public. The passage of the Surface Transportation Assistance Act of 1982 and recently the North American Free Trade Agreement has increased the numbers of large combination vehicles on the highway system. The rise in truck volume (defined as vehicles exceeding 4.5 Mg (10,000 lbs), the int...

This research aims to reduce fuel consumption in transportation systems using vacuum insulation panels (VIPs) for cold storage trucks. The material was Insulation Panels is a custom-made insulator glass fibers pressed at 10 tons per square meter and the thermal conductivity conditions of selected materials ranged between 0.0028 0.007 W/mK has size 12 mm comparative experiment method trucks equi...

Dolphins in a captive environment are exposed to various kinds of stresses. Handling and transportation are stressful events for terrestrial mammals, and such stress may affect immune system function and increase susceptibility to infectious diseases. The same phenomenon could occur in dolphins, however, few studies have reported this in dolphins. The objective of this study was to evaluate the...

Purpose The purpose of this paper is to examine the long-term cointegrating relationship between ocean, rail, truck and air cargo freight rates, as well short-term dynamics these four series. authors also test predictive ability rates on major economic indicators. Design/methodology/approach employ a vector error-correction model using 16 years monthly time series data rate in truck, rail secto...

Title of Dissertation: DYNAMIC DECISION MAKING FOR LESS-THAN-TRUCKLOAD TRUCKING OPERATIONS Behrang Hejazi, Doctor of Philosophy, 2009 Directed By: Professor Ali Haghani Department of Civil and Environmental Engineering On a typical day, more than 53 million tons of goods valued at about $36 million are moved on the US multimodal transportation network. An efficient freight transportation indust...

In the academic and professional literature on freight transportation, computer-based planning methods have a long time ago been identified as a means to achieve cost reduction through enhanced transportation operations efficiency. More recently, inter-firm collaboration in transportation planning has been investigated as a means to provide further gains in efficiency and, in turn, to achieve a...

The purpose of this research project is to study current practices in enhancing visibility and protection of highway maintenance vehicles involved in moving operations such as snow removal and shoulder operations, crack sealing, and pothole patching. The results will enable the maintenance staff to adequately assess the applicability and impact of each strategy to their use and budget. The repo...

In the highly fragmented truckload transportation industry a substantial fraction of truck movements involves empty trucks, i.e., involves moves that reposition trucks. However, reducing the amount of truck repositioning is difficult because the need for a carrier to reposition its trucks depends on the interactions between the shippers the carrier is serving. Through collaboration, shippers ma...
