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...
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...
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...
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...
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...
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...
Summary of Highway Product Evaluation Practices and HITEC Needs Survey
This report (CERF No. 94-5012) contains the results from a survey conducted by the Civil Engineering Research Foundation (CERF), the research affiliate of the American Society of Civil...
Poland Gets Moving
Poland's transportation network is a victim of two world wars, foreign domination, and neglected maintenance, but there are ambitious plans to rebuild the road and rail systems....
Chicago Automates Expressway Lanes
Chicago motorists will soon reclaim another rebuilt expressway in October with substantial completion of a $450 million, 7.5 mi portion of I90/94, the John F. Kennedy Expressway. The two...
