Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....
The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....
Wharf Stands on Stone Columns
A wharf was constructed in New Orleans on very weak soils. To prevent lateral and vertical movement of the soil, normally the entire wharf and adjacent structure would be founded on steel...
CPM Harnesses Mammoth Powerplant Job
One of the largest air quality control retrofit projects in the U. S. is at the Sammis Plant of Ohio Edison Co., along the Ohio River 40 miles west of Pittsburgh. The coal-fired plant's...
Maintaining Our Goals
Setting goals is easier than achieving them and, once achieved, they must not be viewed as final accomplishments to put behind us - they must be sustained. Although goals are essentially...
On-Line Computerized Maintenance Management
Maintenance is the last cost saving frontier of scientific management. Top management has concentrated on production for generations, largely ignoring maintenance. The attitude of 'fix...
An Infrastructure-Based Strategy for Guiding Reconstruction, Development and Reconciliation in Lebanon
In 1979 an agreement was entered into between the CDR, U. S. A. I. D. , and the American University of Beirut (AUB) whereby an interdisciplinary team of AUB researchers would develop a...
Rehabilitation of the CNW and ICG Railroads
The railroad industry is an indispensable part of the American economy. However, the railroad infrastructure was allowed to deteriorate to the extent of having 5. 4 billion in deferred...
Earth Retention & Noise Absorption Using Evergreen Planted Walls
There is a new concept in wall design used for retaining walls, free standing noise absorbing walls and rock revetments. The Evergreen System is comprised of large prefabricated concrete...
Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Learning From Failure
Innovative engineering design involves assumptions about the future use and behavior of a structure. By understanding and learning from the infrequent but spectacular large failures, engineers...
Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
Molikpaq Deployment at Tarsuit P-45
An overview is provided of the engineering considerations and approach to deployment of the Molikpaq. Topics addressed include site investigation, foundation preparation, berm construction,...
Overview of Artificial Island Design and Construction in the Arctic
An overview is provided of the design and construction of artificial islands in the Arctic. Since the early seventies more than 20 islands have been constructed in the Alaskan and Canadian...
Geotechnical Features of Fur Seal Island Design
In summer 1983, Texaco made plans to construct an artificial island in Harrison Bay of the Beaufort Sea to serve as a platform for exploratory drilling. Fur Seal Island is to be located...
Arctic Island Construction
The history of island building in the Beaufort Sea of Canada and the United States is reviewed. Construction methods are discussed. These include hauling material from onshore in both...
The OCEANWHEEL Artificial Island
The compression rim and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
Modular Construction Technology for Arctic Islands
In order to investigate the possibilities for application in the Arctic of new generation construction vessels, a conceptual design of a production island retained by crane-installed concrete...
Porewater Pressure in Clays Below Caisson Islands
Unfrozen lightly overconsolidated clays are a significant factor in the design and performance of exploration caisson retained islands in the Canadian Beaufort Sea. At two sites (Tarsiut...
