The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...
Different Methods to Compute Pollutant Dispersion Around Buildings
Different methods to approximate the advection terms currently in use are reviewed. Holly-Preismann (HP) cubic interpolation using method of characteristics, Chapeau function (CF) method...
Intelligent Tutoring Systems to Aid Water Treatment Plant Operators
Training for water treatment plant operators exists primarily through short courses at colleges or technical schools, self-study manuals, and on-the-job training. Intelligent tutoring...
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
Global Network Optimization for Pavement Management
In a state-wide pavement management system, the highway network can be divided into a number of road categories based on traffic level and geographical region. Network optimization analysis...
Calibration of a Highway Traffic Assignment Model for the Manhattan Central Business District
This paper describes the application of a traffic assignment model, specifically the TRANPLAN model, in New York City together with the methodologies and the satellite programs that were...
Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...
DETMOD: A Desktop Estuarine Transport MODel
A microcomputer based numerical model designed to simulate the transport of substances within an estuary is presented. The Desktop Estuarine Transport MODel (DETMOD) features a Graphical...
Electronic Yellow Pages for Pre-trip Planning Systems
An attempt has been made to introduce Electronic pages or Electronic yellow pages which work similarly to Yellow Pages. The overall system is divided into user interface, network building,...
Data Fusion for an ATIS Operational Test: Description and Computational Issues
The ADVANCE project in the Chicago Metropolitan area is the largest operational test of Advanced Traveler Information System (ATIS) technologies in the U.S. This paper focuses on the process...
Pavement Treatment in Ohio Transportation System
This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those...
A Computerized Methodology for Conducting Pedestrian Gap Studies
this paper will detail recent improvements with the procedure the New York City Department of Transportation utilizes when conducting Pedestrian Gap Studies. These improvements were made...
Contemporaneous Development of Field Data: Transportation Construction Claim Defense
This paper addresses the continuing development of a construction field database system documenting resources applied on the jobsite by Contractors. The paper focuses on the case study...
Dynamic Compaction of Landfill Beneath Embankment
This paper presents the results of a highway project where dynamic compaction was used to densify a closed landfill prior to constructing highway embankments over the landfill. The purpose...
Quantification of the Mechanisms Controlling the Removal Rate of Volatile Contaminants by Air Sparging
Air sparging is a technology for removing dissolved and volatile phase chemicals (VOCs) from the saturated zone. It is used in conjunction with soil vapor extraction (SVE) and sometimes...
Contribution of Waterborne Radon to Home Air Quality
A controlled experiment was performed to explore the contribution of waterborne radon to home air quality and the effect of radon removal from a centralized water system on indoor radon...
New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...
Flood Propagation on Mobile Beds under Mountainous Flow Conditions
An implicit finite-volume scheme is used to solve the shallow water equations under mountainous flow conditions. The algorithm is stable for sub- and supercritical flows and moving internal...
Reliability and Validity of Modeling Sedimentation and Debris Flow Hazards Over Initially Dry Areas
Extreme floods may inundate populated areas of a river valley that are normally dry. Two-dimensional flow analysis is a useful method for predicting the spatial and temporal behavior of...
