This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...

The restoration of historical transport routes and the creation new ones is a strategic objective most states in modern times. Located at intersection North–South East–West routes, Azerbaijan currently recognised as an important logistics hub. Successful cooperation with European Union countries this field taking place. international passing through territory are very convenient for cargo trans...

The combination of plant cell culture methodology with synthetic chemistry affords an attractive route to the synthesis of complex natural products and related compounds of industrial importance. Plant cell cultures which often provide "unique" enzyme systems can be employed effectively as "reagents" in the biotransformation of synthetic substrates to desired end products. Such conversions are ...

New approaches are required to analyse very large land-use transportation systems in which millions of people make millions of trips each day. New computer technology has enabled packages that model very large transportation systems. Some of these models are reviewed and it is concluded that the TRANSIMS system developed at Los Alamos National Laboratory has the best combination of desirable ch...

We propose a new method to perform urban routing efficiently under capacity constraints. This new method helps with evacuation routing as well as other urban transportation challenges. Traditionally, simulation software or shortest path routing combined with zonal scheduling have been used to solve routing problems. Our method utilizes a state-of-the-art algorithm to connect each source node to...

In 2022 in the Russian Federation, most of urban citizens use services public passenger transport. Moreover, main share logistics falls on bus fleet. According to leading economic experts, this circumstance is primarily due fact that largest cities Russia, large influx private cars, big problems began appear form traffic jams and parking spaces. And there was no alternative personal transport e...

Robustness, or the resilience of a system to failures and attacks without changing its mode operation, is an increasingly important characteristic networks. Even though there are several measures network robustness, they not applicable networks with links between same pair nodes (multiline networks), such as transportation systems. A local index set global indexes introduced capture robustness ...

Road transportation is one of the most important needs of villagers, which is considered as one of the important infrastructures in the development of a region. Undoubtedly villages are better equipped with the development of communication routes, especially highways, and their problems and problems are reduced. In this research, the most important consequences and factors affecting the Khoramz...

OpenTripPlanner was identified as the most promising open source multimodal trip planning software. OpenStreetMap, which provides mapping data to OpenTripPlanner, is one of the most well-known open source international repository of geographic data. General Transit Feed Specification, which provides transportation data to OpenTripPlanner, has been the standard for describing transit systems and...
