Delineation Effectiveness for Alcohol Involved Accidents
The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented...
Sighting Safety
This paper examines the interrelation between drivers' visual needs and the road environment. Specific elements of visual limitation and drivers at greatest risk are identified....
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...
Vibration Tests of Reservoir Structures Outlet Tower and Footbridge
This paper presents a field test procedure used in determining the dynamic properties of an outlet tower and footbridge for a major reservoir. Such factors as virtual water mass, soil-structure...
Some Aspects of Bridge Instrumentation
This paper provides some guidelines about the proper arrangement of strong motion instruments for the proper assessment of some particular phenomena that have been either observed in past...
Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...
Response of the San Juan Bautista 156/101 Bridge to the 1979 Coyote Lake Earthquake
Strong-motion accelerograms are used to examine the response of a multiple-span highway bridge to earthquake loading. Estimates of modal frequencies and damping values for the first two...
Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...
Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...
Changes in Bridge Deck Flutter Derivatives Caused by Turbulence
This paper discusses some of the results of a wind tunnel study that tested the aeroelastic stability of section models in smooth and gusting flow. Wind gusts several times longer than...
A Discrete Model for the Estimation of the Elastic Abutment Stiffness
The purpose of this paper is the presentation of a simple method for the estimation of the abutment stiffness. In this method, the abutment is represented as a uniform rigid plate with...
Dynamic Response of Highway Guardrail Post Foundations
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...
Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...
Reshaping Providence
By moving railroad tracks, river banks and several roadways, Providence, Rhode Island is reclaiming some 45 acres in its downtown and capital districts. This public works package is the...
Monitoring a Bridge's Pulse
The Sunshine Skyway Bridge, which collapsed in 1980, is being replaced by the Florida Department of Transportation. The new Sunshine Skyway Bridge, which spans Tampa Bay between Bradenton...
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...
Salvaging the Zilwaukee
In 1982, construction of the Zilwaukee Bridge in Michigan was disrupted when the launching truss failed to hold a precast concrete segment near Pier 11N, severely deflecting the cantilever...
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...
Bridge Management: Computer Aided Priorities
