Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...

recent years have brought a great deal of expansion to the economic systems of developing countries. although they serve as vital link of economic activities, the transportation network of these countries have not grown proportionally. since transportation investments is a a substantial portion of the national budget, a good knowledge of each mode's various characteristics is essential, wh...

Since completing a " Trend-Delphi " based regional forecast and transportation plan in 1996, Metro has developed an integrated transportation and land use model (Metroscope). We are presently using the model to explore several regional growth management options as well as produce a new regional forecast and transportation plan. Comparing our Metroscope results to our previous forecast reveals t...

Five major sources for the ambient aerosol in Gainesville, FL were sampled by using a MicroOrifice Uniform Deposit Impactor (MOUDI) and a University of Washington Mark III Cascade Impactor. The samples were analyzed for carbons and ions. Soil dust, unpaved road dust, cement dust particles and marine aerosols were mainly in the coarse mode, while particles from transportation showed a bi-modal o...

The National Transportation System (NTS), an outgrowth of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), is proposed in this research as an analytical tool to guide national transportation policy-making. The NTS must be based upon measures of transportation performance that are intermodal, user-oriented,. and suitable for tracking the environmental, social, and economic o...

Given the impact of transportation costs on both supplier selection and inventory replenishment decisions in today’s enterprises, this article addresses both problems simultaneously by proposing a mixed integer nonlinear programming model to properly allocate order quantities to the selected set of suppliers while taking into account the purchasing, holding and transportation costs under suppli...

As the automotive industry has been striving to enhance its efficiency, competitiveness, and sustainability, great focus is often placed on opportunities for improving its supply chain operations. We study the effect of introducing multiple modes of transportation in an industry-motivated production and transportation problem involving short-term automotive supply chain planning.
