Fault-Tolerant Computing Architecture for MF 88 and MP 89 Rolling Stock
For several years now, the French and the foreign railway industries have witnessed the development of a new generation of on-board computer systems for rolling stock. It mainly features...
Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...
Simulation of a Vehicle Platoon Control System for Automatic Highway Using the Fuzzy Control Concept
This paper discusses the concept of the longitudinal control of vehicle platoons on the highways. The paper discusses the simulation of vehicles with non-linear properties, such as air...
Academic Research Efforts in the GuideStar IVHS Program
The Minnesota Department of Transportation (Mn/DOT) and University of Minnesota officials, realizing that Minnesota was among the leaders in both research and implementation of advanced...
Design Experience Gained Through Physical Modeling of Small-Craft Harbors
A research work unit has been initiated to determine the state-of-knowledge of small boat harbor design. Existing design criteria for small-craft harbor design is based primarily on 'rule-of-thumb'...
Predicting Sedimentation in Shallow Draft Coastal Ports
The U.S. Army Engineer Waterways Experiment Station is conducting a study to develop and improve design guidance for shallow draft coastal ports. As part of this effort and to fill gaps...
A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...
Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...
Landing on Frictionless Surfaces
Who in his right mind would deliberately land an airplane on a frictionless surface? Unfortunately, professional pilots occasionally encounter situations where the friction between rubber...
Alternative Airfield Pavement Quality Control
In recent years, the cost of maintaining quality control during airfield construction projects has concerned airport operators and engineers alike. This paper addresses the possibilities...
Applications of Advanced Technologies in Transportation Engineering
This proceedings,
Riverbank Renewal
In Providence, project teams from the public and private sector worked side-by-side, rerouting two rivers and constructing a new corporate headquarters. What made the task more challenging...
Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
Dynamic Load Computation for Flexible Guideways Under Moving Vehicles Within a Multibody Approach
This paper addresses the problem of the dynamic interaction of vehicles with their supporting guideway. Because of topographical and environmental reasons, modern railways and magnetically...
Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...
The Estimation of Allowable Strength Based on Fatigue Reliability of Welded Part and Base Metal of Rail in Korea
In the allowable stress design, the safety of structures have been ensured by safety factor based on static strength. Under dynamic loading condition, the allowable stress based on allowable...
The Prefab Tunnel
Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...
