Level of Service in Bridge Management Systems
The Federal Highway Administration's Sufficiency Rating is not adequate for evaluating bridges. It ignores fundamental bridge characteristics and is far too subjective. The Level of Service...
Bridge Management System Implemented in Thailand
The latest ten years' economic growth in Thailand and the associated increase in roadway and railway traffic has exposed the existing bridge structures as bottlenecks of these transportation...
Development and Application of a GIS-Based FTIMS
This paper presents the development of a GIS-based freeway traffic information management system (FTIMS) for the Sun Yat-Sen National Freeway of Taiwan. A two-stage analytical hierarchy...
Using a Geographical Information System to Facilitate Implementation of a Pavement Management System
One of the challenges facing local government is the management of its infrastructure. An important part of this process is the development of a pavement management systems to protect...
A GIS-Based Rail Infrastructure Management System
Computer-based models and analytical techniques are powerful components of infrastructure management systems. However, the availability of data sets significantly affects the usefulness...
Innovative Contracting Practices in Developing an Advanced Freeway Management System
Throughout the nation, many public agencies have determined to incorporate time saving and cost effective project innovations while maintaining and upgrading project quality. One possible...
Programme Management in Highway Region
In the beginning of the 1990's FinnRA suggested decreasing resources for the Lapland highway district whereas the district felt that such a policy would have very harmful long term effects....
Coordination of ISTEA?1991 Management Systems
Following the successful development and implementation of pavement management concepts, the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains the provision that...
The Transrapid EMS Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application. The maglev system uses contactless electromagnetic suspension and three...
Development of a Superconducting Maglev System

Long-Term Pavement Performance Program for Years 1992-1997: A Strategic Plan
The Federal Highway Administration (FHWA) began operational management of the Strategic Highway Research Program's (SHRP) Long-Term Pavement Performance (LTPP) program on July 1, 1992....
Equipment Systems for the Commercial Production of Modified Asphalt
A considerable amount of research has been centered on various asphalt modifiers and their effect on rheological properties. As the paving industry is now focusing on high performance...
Validation of SHRP Performance Graded Binder Specifications Using Field Simulation Testing Equipment
The Strategic Highway Research Program (SHRP) was initiated to improve the effectiveness of laboratory test methods in predicting field performance. European highway agencies are using...
How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...
Pavement Repair Automation
Faced with aging and decaying road systems, continual downsizing of government staffs and increasing budget shortfalls, roadway maintenance needs some help. That help is on the way. It's...
Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...
Future Improvements for Design of Flexible Pavement Structures
The first set of data analyses on the National Pavement Data Base (NPDB) derived from the Long-Term Pavement Performance (LTPP) activities have been completed. The results from sensitivity...
Long-Term Pavement Performance (LTPP) Program in Japan
Japan's `Manual for Design and Construction of Asphalt Pavement' is based on technical results from the AASHO Road Test in 1960's. Strategic Highway Research Program (SHRP) is a much bigger...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
Managing Maintenance from a Business Viewpoint
