Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...
Managing the Russian River Aggregate Resources
As a result of analyzing the Russian River and its capacity to provide gravel, and through a sound examination of the geomorphology, hydrology, and groundwater conditions, the Sonoma County...
Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
MPOS Become VIPS
The 1991 Intermodal Surface Transportation Efficiency Act made metropolitan planning organizations very important players in transportation decisionmaking. MPOs have been around since...
Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
Uncertain Reasoning in a Pavement Management System
A major objective of a Pavement Management System (PMS) is to assist highway engineers and managers in making consistent and cost effective decisions related to maintenance and rehabilitation...
The Safety Advisor: An Interactive Object-Oriented Program for Assessing the Safeness of Roadway and Roadside Designs
This paper describes an object-oriented software tool for performing safety assessments of roadway designs. Safety assessments are used to estimate the effect of changes in roadway characteristics...
FEM in a Design Code Environment
The results obtained from the use of finite element based analysis tools have created a new problem for designer: Which numbers do we use to check against Code limits? Most of the commonly...
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...
Analysis of I-Girder Highway Bridges
Analysis of a bridge superstructure is complicated by the general geometric and loading conditions. Presented in this paper are three dimensional finite element modeling techniques used...
Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...
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...
A Speed Prediction Model for New Zealand Highways
This paper outlines a limiting speed model using probabilistic techniques to simulate the different types of vehicles and their performance along a two-lane rural highway. The road to...
ESPADD.BR: Expert System Producing Automated Designs and Drawings for Bridges
This paper presents the logic and methodology used in developing an automated software system for designs and drawings of bridges. Its primary purpose is to design and draw highway bridge...
Automated Design of 3-D Highway Sign Bridge Structures
A PC-based computer analysis/design program for 3-D Sign Bridge Structures including Pre- and Post-processor has been developed. The analysis of thirty different types of sign support...
Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...
Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...
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,...
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...
