Performance Evaluation and Optimization of Transit Operation
This paper discusses the use of a Performance Evaluation Model in evaluating the effect of short term policy changes including fares, service frequencies, route coverage, and route alignment....
Meeting the Infrastructure Challenge of the 1980's
The future of the nation demands a solution to critical infrastructure problem. The public works facilities must be maintained, restored, and added to. The condition of these facilities...
The State's Prospects for Infrastructure Rehabilitation
In November 1982, at Governor Spellman's initiative, Washington State became one of six states participating in the National Infrastructure Analysis, sponsored by the Joint...
Inventorying the System/Inspection Introductory Remarks
A major sewer system evaluation survey is nearing completion in the seven communities which make up Special District No. 1 of the East Bay Municipal Utility District. A major effort has...
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...
Who is Managing the Rebuilding of our Infrastructure
Determining the nationwide infrastructure needs and identifying the organizations responsible for this assessment are complex processes. Yet, if this nation is to have an organized, orderly...
Infrastructure Awareness: Successful Techniques
The need to rehabilitate and upgrade our infrastructure systems, specifically the systems of water supply and distribution, wastewater collection and treatment, bridges, highways and mass...
Getting Started
The need for increased funding for infrastructure maintenance and rehabilitation is a well recognized problem at all levels of government. Obtaining those funds has proven a difficult...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
Probabilistic Description of Ice Forces on an Offshore Arctic Structure
A probabilistic simulation model has been developed to describe the frequency and outcome of multi-year ice floe encounters with a fixed offshore structure located in the Beaufort Sea,...
Selection of Environmental Design Criteria for Arctic Structures
Where data are insufficient for calculation of extremes using probability theory, design criteria may be reasonable defined by combining available data, knowledge of physical processes...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...
Validation of the CICE Code for Ice Ride-Up and Ice Ridge Cone Interaction
The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves...
Deep Water Bering Sea Development Concepts
A brief description of the major environmental factors that a structure used to produce oil and gas in the deep water Bering Sea would have to cope with is presented. In particular, the...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
Multi-Truss Design for Tower
A modified structural steel system of outrigger trusses and belt trusses bolster the 54-story Equitable Tower West. Located in New York City, the building's structural system...
Management Secrets of Top Consultants
Leaders of five consulting civil engineering firms, which are considered among the best managed, discuss management strategies. In all cases, carefully selected personnel is considered...
