Effectiveness of Real-Time Information Strategies in Situations of Non-Recurrent Congestion
The effect of real-time information on the performance of a traffic commuting corridor in situations of non-recurrent congestion is studied using a dynamic simulation model. Non-recurrent...

Contact-Free IC Cards for New Railway Ticket Systems
Two types of smart cards which can communicate with an automatic gate machine without contact are developed. The first one uses medium wave radio as communication media. The microprocessor...

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...

Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....

Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...

Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...

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...

Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...

The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...

Economic Considerations of Marina Design
The planning and design of a marina involves decision making to optimize the economic return of the entire project. Decisions relating to land-use, water-use, and construction require...

Physical Model Testing of Barbers Point Harbor and Marina Complex
A three-dimensional, physical model study of the Barbers Point, Hawaii harbor and marina complex is being conducted at the US Army Engineer Waterways Experiment Station, Coastal Engineering...

Simplified Tidal-Flushing Model for Small Marinas
This paper describes the development and application of a new water quality screening model - STEAM (Simplified Tidal Embayment Assessment Model). This model simulates the first-order...

Predictive Techniques for Marina Water Quality Assessment
The construction of new marinas in coastal areas requires as assessment of potential impacts on water quality as a part of the permit process. This paper summarizes a study sponsored by...

Application of a Numerical Model to Develop Marina Concepts
A numerical model is presented to evaluate wave conditions in a marina basin for development and analysis of marina concepts. This model is based on the boundary integral equation method...

Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...

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...

Pavement Design by Elastic Layer Theory
The U. S. Army Engineer Waterways Experiment Station has been developing methodology by which airport/airfield pavements can be designed based on elastic layered analysis for the Federal...

The Effects of Runway Roughness on Aircraft Fatigue Life
A computer code developed within the Flight Dynamics Directorate of the Wright Laboratory was used to simulate the dynamic response of heavy aircraft operating on runways with various...

DFW Pavement Management System Implementation
Dallas/Fort Worth International Airport is implementing a comprehensive pavement management program to assist them in identifying and prioritizing maintenance, rehabilitation and reconstruction...
