Road Safety Audit: Prevention is Better Than Cure
Over the past two decades, the emphasis in road safety engineering has been on crash reduction through the development of remedial measures at high frequency sites. Road and traffic authorities...
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...
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...
High Speed Rail Initiatives in Korea
The purpose of constructing a high speed rail on the Seoul-Pusan corridor is many fold: to solve intercity traffic congestions, to save energy, to reduce air pollution, and to make possible...
New Work Zone Safety Devices
Highway maintenance work is one of the most hazardous occupations throughout the world. The growing necessity to repair existing pavements and structures facilities while maintaining traffic...
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...
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...
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....
Traffic Accident Analysis System
While statistical data on traffic accidents are invaluable in devising effective traffic safety measures, the number of data items and samples are vast and they must be processed and edited...
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,...
Early Field Experience with SUPERPAVE
Specific pavement studies of newly constructed, reconstructed or rehabilitated (resurfaced) pavement sections were used to provide an estimate of the relative influence of key pavement...
Real Time Public Transport Information Systems in
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...
Bonded Concrete Overlays for Rehabilitation of Continuously Reinforced Concrete Pavement
As a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA), significant funding is now available for the rehabilitation of the nation's Interstate highway system....
Machine Vision Based Traffic-Adjusted Intersection Signal Control
This paper describes some of the available machine vision systems and how they can be effectively used for traffic control at an intersection. A set of rules have been defined which make...
ICAO's ACN-PCN Method and Aircraft-Pavement Interaction
Multi-wheel gear assemblies of future aircraft are not compatible with pavements rated in the ACN-PCN system given by the International Civil Aviation Organization (ICAO). The Aircraft...
Pavement Design Considerations for Heavy Aircraft Loading at BAA Airports
BAA operates seven airports in the United Kingdom. Two of them, Heathrow and Gatwick, handled 61 million passengers in 1991 with 543,000 air transport movements, 25% by wide-bodied aircraft....
Densification of Asphalt Pavements by Traffic
Since asphalt pavements rut when the voids are filled with asphalt (and voids can become filled by traffic densification) the voids that develop under traffic are vital to any mix design...
Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...
The Fundamental Gap in Urban Transportation
This is not a technical paper. It is perspective paper, designed to detail the failure of current urban transportation strategies and call for new thinking and action responsive to the...
