In order to improve profitability, freight forwarding companies try to organize their operational transportation planning systematically, considering not only their own fleet but also external resources. Such external resources include vehicles from closely related subcontractors, autonomous common carriers on the transportation market, and cooperating partners in horizontal coalitions. In this...

In this paper we propose a dynamic Stackelberg game-theoretic model for urban freight transportation planning which is able to characterize the interaction between freight and personal transportation in an urban area. The problem is formulated as a bi-level dynamic mathematical program with equilibrium constraints (MPEC) which belongs to a class of computationally challenging problems. The lowe...

This paper offers the description of an integrated information system framework for the assessment of transportation planning and management. After an introductory exposition, in the first part of the paper, a broad overview of international experiences regarding information systems on transportation is given, focusing in particular on the relationship between transportation system's performanc...

The ALPS (Adaptive Learning and Planning System) project is a three-year effort to design and prototype a next-generation adaptive planning architecture as part of the ARPA / Rome Laboratory Planning Initiative (ARPI). ALPS is being used.within the Planning Initiative to perform large-scale military transportation scheduling, taking a Time-Phased Force Deployment Data (TPFDD) file with thousand...

IN T R O D U C T IO N Population forecasters have estimated that the 1970 census when reported will show close to 75 percent of the United States popula­ tion will be classified as urban. Once again one can expect that the greatest percentage change will occur in the urban fringes of central cities of population range of 25,000 to 100,000. Along with the in­ creased population growth and disper...

The use of Intelligent Transportation Systems (ITS) in motor vehicles is anticipated to dramatically enhance both traffic safety and mobility. Successful large-scale implementation these systems depends critically on the enthusiasm potential users accept them. However, market segmentation has gotten surprisingly little attention at current level ITS technology development, despite fact that it ...

Timber transportation is one of the most expensive activities in forest operations. Traditionally, the goal of forest transportation planning has been to find the combination of road development and harvest equipment placement that minimizes total harvesting and transportation costs. However, modern transportation problems are not driven only by economics of timber management, but also by multi...

ITE JOURNAL / DECEMBER 2004 INTRODUCTION AND SCOPE OF PAPER Planning for freight transportation in urban areas is not performed as commonly or as thoroughly as planning for passenger transportation, despite the fact that one of the seven factors for metropolitan planning specified in the federal legislation (the Transportation Equity Act for the 21st Century) mentions freight. Most planners and...

rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. in the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. with traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. four s...

Transportation departments are beginning to recognize that adaptation for climate change must become an integral part of their planning efforts. However, staff members frequently lack adequate local data, training, or guidance to begin adaptation planning assessments. As a result, climate change adaptation planning has remained generally abstract and lacks specificity needed to identify potenti...
