Implementation of Knowledge-Based GIS: A Case Study
This paper describes work almost complete at North Carolina A&T State University, whose primary purpose was to use the increased capabilities offered by geographic information...

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...

A Symbol-form Mapping Framework for Conceptual Design Support
Engineering design involves a strong notion of the geometric structure of design artifacts. Research efforts to support the geometric aspects of design have concentrated on the representation...

Pen Computers in Civil Engineering
Multnomah County, Oregon has developed 'field-to-office' automation systems incorporating pen computers as a data collection tool. This technology was integrated into civil engineering...

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...

Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...

An Object Oriented Highway Information System in the Client-Server Environment
This paper discusses issues required for the development of an object-oriented (OO) highway information system in a client-server environment based on the System Object Model (SOM) in...

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...

Settlements of Highway Embankments on Soft Lacustrine Deposits
This paper presents the settlement study that was conducted in conjunction with the major freeway expansion project planned through Salt Lake City in which existing embankments will be...

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...

The Control of Settlement Using Geogrids
The applicability of geogrids in reducing settlements has been investigated in the laboratory in two separate studies, in unpaved roads under cycled load applications, and as overlays...

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...

Demonstration Project for Scour Instrumentation
A Federal Highway Administration (FHWA) Demonstration Project was developed to facilitate technology transfer of instrumentation related research to the highway industry. The objective...

Velocity and Turbulence Measurement from the Illinois and Mississippi Rivers
This paper presents a data measurement program that was used for collecting the velocity data associated with barge-tow traffic on the Illinois and Mississippi Rivers and includes a discussion...

Sediment Measurement Instrumentation A Personal Perspective
The development of the suspended sediment samplers in the 1940s was a major contribution to the science of sedimentation and provided for the proper development of dams, reservoirs, and...

Calibration of Movable Bed Model for Armant Area
The morphology of the Nile River, in Egypt, is undergoing continuous changes which causes navigation bottle-necks in some local reaches. About 200 km downstream Aswan, at Armant area,...
