The authors present a procedure for resource allocation among transit agencies for transit fleet management, specifically focusing on the purchase of new buses and rebuilding of existing buses. The model is formulated as a non-linear optimization problem of maximizing the total weighted average remaining life of the fleet subject to budgetary, policy and other constraints. The problem is solved...

This thesis extends the previous literature on urban subcenter formation by introducing congestion cost of transportation. A new model is constructed to analyze the efficiency of private decision about firm decentralization with the presence of unpriced transportation congestion. The model features a linear city with provision of transportation infrastructure oriented toward carrying workers to...

[Motivation:] Environmental sustainability is an important concern. Information and communication technology (ICT) innovation is ambivalently positioned with regard to our rapid development and shortening innovation cycles. On one hand, information technology facilitates the (excessive) usage of resources. On the other hand, ICT can also help to significantly reduce human impact on the environm...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

Effective management of the vehicles plays an important role in transportation sector. There are some novel approaches in software engineering which can be used to dynamically control the trucks. One of the example technologies is multi-agent systems. Multi-agent-based technologies could be used for truck dispatching in real time. The trucks in such systems have their own transportation plan an...

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...
