Railroad hazardous materials transportation route risk analysis is receiving considerable new attention from industry and government. Such analyses are necessary for effective public policy and development of rational risk management strategies. However, route risk analysis is complex and generates results that can be difficult to properly interpret. Risk analyses are intended to provide risk m...

Based on cellular automaton and multi-agent model, we propose a novel hybrid model for distributed simulation of train-group in the railway traffic. An improved cellular automaton model is designed for simulating the underlying structure of the railroad and a multi-agent model is used for dynamic scheduling of the train-group. The combination of both models answers for the distributed simulatio...

From a safety point of view different transportation systems share many properties and requirements. They are all supposed to function correctly, to be failure tolerant and to be associated with only minimal risk. To ensure these requirements formal methods are a great help. The ForMoSA approach provides an integrated methodology for formally analyzing safety-critical transportation systems. On...

Kent State had its beginning nearly a century ago. William S. Kent, a person of vision, donated 53 acres of farmland located on a hill overlooking a small town on the Cuyahoga River. He did so to establish a teacher education school in his community. When I visit various communities in my travels, I always ask, Why does this community or city exist? What is its reason for being? Kent exists bec...

a r t i c l e i n f o Railroads and roads are ubiquitous features in the river corridors of the United States. However, their impact on hydrologic, geomorphic, and ecological processes in fluvial and riparian landscapes has not been systematically explored at regional or continental extents. This study documents the geographic distribution of roads and railroads in the alluvial floodplains of t...

An aircraft livery design comprises comprehensive insignia that include colour, visual, and typographic identifiers. Stagecoaches, railroad trains, steamships all appeared, the term "livery" came to refer interior of these vehicles. Parts airline liveries have become increasingly intertwined with ground transportation, advertising, exclusive airport furnishings, promotional materials, aircrew u...

Abstract In this paper, we examine multiple segments, conventionally analyzed from the perspective of business diversification, perspectives in a multifaceted market. Specifically, based on segmental financial data, conduct an empirical analysis whether increased sales transportation increase profit margin real estate railroad company. The results show that there are two types sidedness among m...

The object of this study is the processes occurrence, exposure to, and redistribution loads in supporting structure a removable module for transportation long cargoes. To adapt platform cars to loads, it proposed introduce with elastic-friction connections structure. In order select optimal profiles module, terms minimal material consumption, calculation was carried out Lira software package. B...
