An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Location and Development of Safety Projects
Projects to be considered for inclusion in the Highway Safety Improvement Program (HSIP) must be part of a prioritized listing in which each project is based on accident experience or...
Evaluation?A Key to Safer Design Standards
Public highways are designed and constructed in accordance with established standards which have been developed over the years as a result of research studies or developed by committees...
Back on a Full Speed Track
A $30 million rehabilitation project is transforming a Massachusetts rail line that shows its age and poor maintenance history. Rehabilitating the line from Bristol County, Mass. to Hyannis...
Explosion Hazards to Urban Structures
Manufacture, storage and transportation of chemicals capable of exploding at energy levels comparable to TNT has increased in recent years. Land areas adjoining such facilities and transportation...
Active Control of Distributed Parameters Structures by Pointwise Control Actions
Several methods have been offered to control a structure. These methods are the optimal control, the pole assignment, the independent modal space control, and the direct velocity feedback....
Optimal Control of Seismic Structures
This paper presents the algorithm for optimal design of structural systems with active tendon controllers and/or active mass dampers. The structure is subjected to earthquake excitation...
Application of Modern Control Theory for Building Structures
Active control systems can be used to reduce the effect of strong-motion earthquakes. During the past two decades, various approaches have been applied to find the optimal control law....
Constrained Viscoelastic Layers for Passive Vibration Control of Structures
Infills with constrained viscoelastic layers for increasing the energy absorption capacity of structures are examined. The infills are expected to 'work' in the...
Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...
An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...
Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...
Port Master Plans and Feasibility Studies
Port projects are cost-intensive long-life irreversible assets, and developing countries particularly limping with resource constraints could not afford the luxury of short-sighted defective...
The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
This paper describes a software package which simulates the operations of marine terminals. The computer programs were designed to assess the effectiveness of the available design alternatives...
Construction Materials for Civil Engineering Projects
The materials of construction in use today have grown in number, increased in complexity, expanded in application and multiplied in utilization over those in use just a short time ago....
Forensic Engineering
Learning from Failures
The activities and qualifications of the Forensic Engineer are summarized in the nine papers published in this book. Procedures for failure investigation are discussed along with failure...
Effectiveness of Highway Safety Improvements
This book contains the thirty papers presented at the third Highway Safety Specialty Conference sponsored by the Committee on Traffic and Safety of the Highway Division of the American...
Highway Quality Level Program
This article describes three versions of BASIC programs for microcomputers, prepared for the Federal Highway Administration, to calculate a statistical measure of highway quality. Using...
CPT/DMT QC of Ground Modification at a Power Plant
The use of 908 static cone penetration test (CPT) and 33 Marchetti dilatometer test (DMT) soundings provided the quality control (QC) needed to improve a power plant site by the use of...
Taming Lively Buildings
Mechanical damping systems are increasingly being used for controlling dynamic responses of tall buildings. Several types of dampers are described, and compared, beginning with the three...
