Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...

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...

Selecting Precast Concrete Building Systems
The development of an integrated computer system to assist in the selection of precast concrete (PC) building systems is described. StructNet, a neural network program, identifies possible...

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...

The Application of Artificial Neural Networks to Civil Engineering
Recently, there has been much interest in the application of artificial neural networks (ANNs) to civil engineering problems. Most applications, however, have been limited to the use of...

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...

An Artificial Neural Network Approach to Pavement Maintenance Decision Support System
An important component of any Pavement Maintenance Decision Support System (PMDSS) is the condition survey and rating procedures. Data obtained from these procedures are the primary basis...

An Artificial Neural Network Approach to Allocating Construction Resources
This paper presents an approach to alleviate the problem of depending upon human expert in allocating construction resources. This approach is using artificial neural networks to capture...

Conceptual Models of Product, Project and Document Data; Essential Ingredients of CIC
A number of current on-going national and international standardization efforts which develop standards for information structures in construction are reviewed in the paper. These concern...

Refinement of Cost Estimates with Artificial Neural Nets
An estimate should be refined for undefined items. Usually, contingency is added to cover any inadequacies in estimate basis definition and inadequacies in estimating methods and data....

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,...

Integrating Computer Application for Pavement Management: A Case Study
This paper presents a case study of the process through which a relational database management system and stand-alone application programs are developed and integrated to form a comprehensive...

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...

Conceptual Design Using Evolutive-Cognitive Computing Techniques
The paper concerns the development of a computer-based capability for conducting conceptual design using emergent(self-organizing) computing paradigms that arrive at a solution through...

Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...

Computer Software for Risk Analysis
The seventh session was directed toward computer software that is designed for use in various aspects of risk analysis. The papers presented discussed the following: application of user-friendly...

In Situ Treatment of VOCs by Recirculation Technologies
Confronted with contaminated land from the world wars and the postwar industrialization period, German researchers and practicing professionals have worked to develop processes for effective...

Impact of GOES Data on Surface Heat Flux Predictions
Surface heat flux is the required input for the Great Lakes Forecasting System (GLFS) in order to predict three dimensional temperature structure of the Great Lakes. Since the flux is...

Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...
