Pioneer Highway
The 1993 Outstanding Civil Engineering Achievement Award goes to the $490 million I-70 Glenwood Canyon in Colorado. The final link in Interstate 70 from Baltimore, Md. to Cove Fort, Utah,...
Hydraulic Performance of Culvert End Sections Designed for Collision Safety
A type of end section for pipe culverts that was designed for collision safety has some favorable hydraulic characteristics. These safety end sections are long and narrow with large steel...
Predicting Critical Scour Stage at Bridges
After an initial level I screening process, most level II bridge scour studies result in recommendations for costly scour countermeasures. Typically, existing transportation budgets cannot...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
The Rokko Island Line of the Kobe New Transit System
Because Rokko Island was planned to be a mini-city with all the typical urban functions, it was essential to provide a means of transportation connecting it with the existing urban center...
Compare: Hampton Roads Congestion Management Program
COMPARE is an acronym given to a traffic congestion management program that has been formulated through the cooperative efforts of all the major Cities and Transportation Agencies in the...
Identifying Transportation Control Measures: a Straighforward Approach to Identifying Transportation Control Measures to Address Concerns with Air Quality
The 1990 Clean Air Act Amendments (CAAA) exemplify society's increasing environmental concern. Regions not attaining the CAAA requirements must develop methods to reduce the pollution....
Trip Rates Adjustments for Impact Assessment and Congestion Management
Evidence that all urban trips are not equal and that trip rates need to be adjusted to reflect the differential contribution of trips to traffic loads and congestion is presented. Adjustments...
Congestion Pricing with Tolls and Subsidies
Though economists have promoted congestion pricing for many years it has, in general, met with public opposition. It is usually argued that congestion pricing is unfair, discriminatory,...
Congestion Management: Right Price
Congested city centers have become a nightmare of traffic planners. They propose a variety of measures to overcome the problem: more funds to road construction, tighter parking controls,...
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...
New Road Safety Initiatives in New Zealand
A considerable number of initiatives have been taken in New Zealand recently to keep pressure on the downward trend in road crashes and casualties. These have included government legislation...
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 Railways and Development in Japan
There is a need to develop an environmentally friendly railway in response to society's needs, implement high-speed operations on existing tracks, and develop a high-quality, high-speed...
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...
