Long term demand for freight movements in North America is expected to increase dramatically in the coming decades. The railroads are poised to take on this additional traffic assuming the capacity is available. Measuring the capacity of these rail lines is complicated by the interrelationships between asset utilization, reliability, and throughput. There is not a single metric that captures th...

This paper presents a multi-agent system for planning, plan optimization and plan executionmonitoring in a real-time railroad transportation scenario. The planning process is implemented as incremental anytime algorithm that is capable of integrating new task specifications in the ongoing planning and planexecutionprocess. An initial solution is obtained by executing thecontractnet protocol for...

Multi-agent system technology has been proposed to model any systems who's resources are distributed (systems that can be found everywhere in the real world). Through system modeling using this technology the system's flexibility and capacity to resolve unpredicted situations that appear inside it, have been improved. In this article multi-agent systems technology advantages and applications ar...

Railroad-related accidents are more dangerous than other transportation accidents in terms of severity and death rate etc. Therefore more efforts are necessary for improving safety. In the mean time, Korean national railroad has researched and invested continuously such as intelligent safety equipments and level crossing between railroad and highway for decreasing railroad-related accident and ...

The Commander, Eighth Coast Guard District, issued a temporary deviation from the regulation governing the operation of the CSX Railroad Swing Span Bridge across Chickasaw Creek, mile 0.0, in Mobile, Alabama. The deviation is necessary to replace railroad ties on the bridge. This deviation allows the bridge to remain closed for eight hours on March 8, 2011. DATES: This deviation is effective fr...

Railway grade crossing is become the major headache for the transportation system. This paper describes an intelligent railway crossing control system for multiple tracks that features a controller which receives messages from incoming and outgoing trains by sensors. These messages contain detail information including the direction and identity of a train. Depending on those messages the contro...

Since the mid-1990s, the U.S. Department of Transportation (U.S. DOT) Federal Railroad Administration (FRA) has sponsored research, conducted by the John A. Volpe National Transportation Systems Center of the U.S. DOT Research and Innovative Technology Administration (RITA), aimed at integrating Positive Train Control (PTC) and Intelligent Transportation System (ITS) technologies. The objective...

The logistical efficiency and viability of the algorithms in comparison with linear programrural transportation system is a growing conming for solution of models with a network cern of agricultural producers, transportation structure. Fuller et al. [4] used a network flow regulators, and policy makers. Railroad facility model in combination with implicit enumeralimitations, abandonment of rail...
