Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...

Composite Construction?Recent Past, Present and Near Future
The present paper covers a shorter time span. It is divided into three parts: recent past, present and near future. The remarks regarding the recent past are limited to my personal experiences....

New Developments in Eurocode 4
The European Community has initiated the preparation of a set of harmonized structural codes. Eurocode 4 is the code for the design of composite steel and concrete structures. The first...

New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...

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
