road transportation by way of automobiles is a very convenient means of transportation. today, the most detrimental consequence of developing transportation systems in a country is traffic accident that places a huge financial burden on society. this paper investigates the role of information systems in transportation safety that leads to improved planning and operation of the transportation sy...

One of the major obstacles in the process of national development, is the disruption in regional balance construct. As has been noted in some studies the existence of regional inequity leads to domination of some regions to surrounding regions and causing political and economic challenges in developing countries. And given that transportation is one of the components of region, undoubtedly equi...

In ordinary transportation problems, it is always supposed that the mileage from every source to every destination is a definite number. But in special conditions, such as transporting emergency materials when natural calamity occurs or transporting military supplies during wartime, carrying network may be destroyed, mileage from some sources to some destinations are no longer definite. It is u...

Recently the rapid development of Internet of Thing (IoT) brings new opportunity to Intelligent Transportation System (ITS). The key problem is how to process the huge events generated by IoT to support ITS. In this paper a proactive complex event processing method is proposed for congestion control in ITS. Based on complex event processing, this method predicts the traffic flow using a multi-l...

Travel time prediction is an indispensable for numerous intelligent transportation systems (ITS) including advanced traveler information systems. The main purpose of this research is to develop a dynamic travel time prediction model for road networks. In this study we proposed a new method to predict travel times using Artificial Neural Network model because artificial neural network has exhibi...

This paper presents a branching method for the solution of the fixed charge transportation problem. Starting with a linear formulation of the problem, we develop the method which converges to the optimal solution. The method is based on the computation of a lower bound and an upper bound embedded within a branching process. We present a detailed numerical example to illustrate the proposed meth...

Traditional approaches for some applications of Intelligent Transportation System(ITS), such as license plate tilt correction and vehicle speed estimation generally require feature extraction, however, feature extraction is a difficult task in complex traffic environment, and it is prone to be affected by the moving status of object and dynamic environment. In this paper, we tried a new analysi...

In recent years, the value-added created in the transportation industry is about 8 percent of GDP of Iran. Due to the high-induced effect of transportation sector on the whole economy, analyzing transportation production function and its determinant is of great value for policymakers. The objective of the present research is to estimate the transportation production for the case of Iran and to ...

Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems...

New algorithm named, Modified Vogel’s Approximation Method (MVAM) is proposed for solving fuzzy transportation problem. This algorithm is more efficient than other existing algorithms. The procedure for the solution is illustrated with a numerical example. Further, comparative study among the new algorithm and the other existing algorithms is established by means of sample problem.
