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...

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...

Operation and Maintenance Plan for Marinas
A operation and maintenance (O&M) plan for marinas is presented to describe the process and establish basic parameters that can be used as guidelines to more comprehensive site-specific...

Organisation Structure and Control
With today's rapidly changing world economies and a variety of other pertinent factors, the euphoria of the past few years is fast dwindling and a professional approach in...

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...

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...

Prediction of Airfield Pavement Responses Using Transfer Functions
A methodology is presented which will aid in the evaluation and maintenance of airfield pavements. Predictions of an airfield pavement's behavior to multiple types and magnitudes...

Results of the 1989 ASCE Airfield Pavement Survey
In November of 1989, the American Society of Civil Engineers Airfield Pavement Committee sent out questionnaires to airfield pavement engineers across the country to assess the most recent...

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...

Geotechnical Engineering Congress?1991
This proceedings, Geotechnical Engineering Congress 1991, consists of papers presented at the Geotechnical Congress held in Boulder, Colorado...

Slow Sand Filtration
This report, Slow Sand Filtration, was prepared by the Task Committee on Slow Sand Filtration of the Water Supply Committee of the Environmental...

Reliability Analysis for Offshore Structures
This study presents the reliability analysis of an offshore structure. The mechanical model includes various elasto-plastic diagrams with and without the combination of the normal force...
