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...
improper transportation of agricultural materials causes mechanical damage to them. the damage isdepended to the physical and mechanical properties of the product and properties of the appliedforce. vibration generated by vehicles during road transportation causes shake the product, contactit with carrier bin and other components, tissues deformation and damage to product. this researchwas cond...
Based on the acceptability index for comparison of any two imprecise values, efficient algorithms have been proposed in literature solving shortest path (SP) problem when weights connected arcs a transportation network are represented as interval numbers. In this study, generalized Dijkstra algorithm is to handle SP with weights. Here it shown that once chosen, converted into crisp one, which e...
Globalization is a word that probably heard and used by everyone in all regions of the world. The developments communication, telecommunication, transportation logistics opportunities brought information age technology geographical boundaries can easily be crossed. world has almost turned into “global village” this transformation caused positive negative effects economic, social, cultural, poli...
Urban mobility is a massive issue in the current century, being widely promoted need of adopting sustainable solutions regarding transportation within large urban centres. The evolution technologies has democratised smart cities to better plan and manage their solutions, without compromising social, economic, environmental impacts. Pursuing carbon neutrality climate agreement goals, soft one mo...
The objectives of the paper is to review the conflicting requirements and needs of existing telecommunication network testing approaches, services and equipment, in order to provide a simple but powerful solution that allows automated and standardized testing activities. We present in the paper a progressive transition from the current proprietary practices, to a distributed and fully TMN compl...
We describe our unifying architecture for multipoint-to-multipoint communications in ATM networks which meets the diverse requirement of group communications and permit a large degree of control on the multicast group. With an integrated use of a name space, the scheme allows scalable extension to large scale wide area multicast communications. We also enable exible control on routeing architec...
The existence of a series of problems in transportation management of public and personal vehicles causes to consider intelligent transportation systems. Hence, here we investigate to introduce and the performance of intelligent transportation system ITS which is among new technologies in information technology and at last the importance and necessity of lack of delay in data and informat...
