Concrete Bridge Protection Repair & Rehabilitation
A methodology for the selection of cost effective solution(s) to the protection, repair, and rehabilitation of concrete bridges in chloride-laden environments is presented. The methodology...

Selecting Bridge Protection and Rehabilitation Options
This paper describes a recently developed procedure for use by bridge engineers making protection or rehabilitation decisions for concrete bridges. The methodology determines the most...

An Evaluation of the Strategic Highway Research Project Packing Handbook
The objective of this paper is to present the use of the November 8, 1991 SHRP C-206 report entitled `Packing Handbook - A Guide to the Optimal Gradation of Concrete Aggregates'. The purpose...

Condition Data Reduction for Pavement Management
A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should...

Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...

Managing Maintenance from a Business Viewpoint
Today's sophisticated maintenance management systems allow supervisors to plan, schedule, monitor and evaluate the maintenance function at a level and speed our predecessors heretofore...

Getting Ahead of Snow and Ice
Winter maintenance is not the same anymore. New weather forecasting technologies are permitting snow and ice fighters to better predict when unsafe winter weather conditions will occur....

Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...

Wetland Conservation Plans as Contexts for Transportation Planning
Construction of major, new roadways, particularly in metropolitan areas, initiates subsidiary affects that impact the environment in a variety of ways and increasingly over time. Not the...

The Pontis Bridge Management System
A committee of the Federal Highway Administration and six of the United States has completed a network-level bridge management system, called Pontis, to optimize budgets and programs for...

SNCF High-Speed Trains: 15 Years of Design, 13 TGV Generations
Less than ten years after the first high-speed revenue service, SNCF has just placed an order for a third generation of TGV rolling stock: the double-deck TGV. Between two generations,...

Real Time Public Transport Information Systems in SCOPE
The objective of this work is to demonstrate the use of Advanced Transport Telematics (ATT) in a multimodal transport environment. The focus of the work is on the integration of ATT methods...

Connecticut I-95 Incident Management System
Strategies for minimizing the impact of freeway incidents on traffic flow/congestion are reffered to as 'incident management'. The incident management process involves the following: reducing...

Issues in GIS-Based Subsurface Data Management
Obstacles and barriers preclude an interagency GIS application for managing spatially-related subsurface data. Such a system would enable geotechnical and earthquake engineers from state...

National Geotechnical Experimentation Sites?Central Data Repository
A central data repository is in the process of development for the recently-established system of U.S. geotechnical experimentation sites. Data which will be available for most of these...

The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...

Some Considerations for the Use of Geographic Information Systems
GIS have become widely used. Geotechnical earthquake engineers need both to understand what distinguishes a GIS form other data base systems and to make clear the purpose, use, and maintenance...

A Geotechnical/Earthquake Engineering Information System?Expanding the GIS Conceptual Framework
Data in a typical geotechnical and earthquake engineering study, encompass a variety of sources of information from site investigations, field instrumentation, dynamic computer simulations,...

Accuracy Requirements for GIS-Based Seismic Risk Assessments
Accurate assessments of potential earthquake damage and casualty risk are essential to the design of seismic hazard mitigation policies and seismically oriented engineering practice. More...

Earthquake Risk GIS Analysis for Ningxia Hui Autonomous Region, China
The Ningxia Hui Autonomous Region is a small autonomous region in the eastern part of northwest China and below Inner Mongolia with an area of 66,400 square meters. Ningxia's population...
