Impact Evaluation Of The Traffic Alcohol Program In Lexington, Kentucky, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

This report is an evaluation of increased police enforcement to reduce alcohol-related accidents in Lexington-Fayette County, Kentucky. Three types of data were coIlected as a means of evaluating the Traffic Alcohol Program; accident data, arrest and adjudication data, and cost-effectiveness data.

Results from before-and-after comparisons and time-series analysis show alcohol related accidents decreased significantly during the study period. When comparing two years before with three years during the increased enforcement, the percent reduction in alcohol-related accidents was 28.1 percent using standard before and after analysis and 29.1 percent using time-series analysis. During the same time period, alcohol related fatal or …

Randomized Routing On Fat-Trees, Ronald I. Greenberg

Computer Science: Faculty Publications and Other Works

Fat-trees are a class of routing networks for hardware-efficient parallel computation. This paper presents a randomized algorithm for routing messages on a fat-tree. The quality of the algorithm is measured in terms of the load factor of a set of messages to be routed, which is a lower bound on the time required to deliver the messages. We show that if a set of messages has load factor lambda on a fat-tree with n processors, the number of delivery cycles (routing attempts) that the algorithm requires is O(lambda+lgnlglgn) with probability 1-O(1/ …

Air Force Problems With Birds In Hangars, Timothy J. Will

Eastern Wildlife Damage Control Conference: 2nd (1985)

The Air Force's Bird-Aircraft Strike Hazard (BASH) Team has been dealing with bird hazards to aircraft for over ten years, primarily through awareness programs, direct assistance to military bases, and through R&D aimed at world-wide BASH reduction. As with any problem where a biological system (in this case, birds) is involved, diversification is important in developing solutions. The BASH Team has recommended a variety of methods for working with hazards from birds. One area of particular concern is the nuisance of pest birds in hangars. These structures are extremely alluring to birds, which seek the roof-supporting I-beams and bars for …

Vibration Coupling In Continuous Belt And Band Systems, C. D. Mote, W-Z Ben Wu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Small transverse oscillation of an endless band supported by wheels couples the response of the free spans of the band to oscillation of the wheels. The coupling arises from the finite curvature of the free spans of the band when its bending stiffness is finite. Significant modeling error can occur if a single span of the band is modeled as a simply supported, axially moving beam. The coupling provides an opportunity to dissipate vibration energy. Experiments and finite element analyses support the coupling discussion presented. © 1985 Academic Press Inc.

Load And Resistance Factor Design Of Cold Formed Steel Comparative Study Of Design Methods For Cold Formed Steel, Lan-Cheng Pan, Wei-Wen Yu, Brian K. Snyder

CCFSS Library (1939 - present)

Allowable Stress Design is the current method used to design cold-formed steel structural members and connections. In this design approach, factors of safety are used to compute the allowable design stresses which are compared to the actual maximum stresses that will occur in the member during the life of the structure. In recent years, the Load and Resistance Factor Design (LRFD) method has been developed for the design of hot-rolled steel shapes and the design of cold-formed steel structural members. This method is based on probabilistic and statistical techniques to account for the many uncertainties involved with the actual design. …

Design Of Automotive Structural Components Using High Strength Sheet Steels - Results And Evaluation Of Stub Column Tests For Unstiffened Curved Elements, Wei-Wen Yu, M. Brad Parks

CCFSS Library (1939 - present)

I. INTRODUCTION A. GENERAL In the past few years, a dramatic increase in the use of high strength sheet steels in automobiles has been brought about by the demand for improved fuel economy and safety of motor vehicles. Many of the automotive structural components, which are made of high strength sheet. steels, consists either partially or totally of curved elements. Therefore, it was decided to include an investigation into the structural behavior of curved elements as a part of a research project entitled, "Structural Design of Automotive Structural Components Using High Strength Sheet Steels." The research project began in early …

Load And Resistance Factor Design Of Cold-Formed Steel Revised Tentative Recommendations - Load And Resistance Factor Design Criteria For Cold-Formed Steel Structural Members With Commentary, Wei-Wen Yu, Theodore V. Galambos

CCFSS Library (1939 - present)

The "Allowable Stress Design Method" has long been used for the design of cold-formed steel structural members. The "Load and Resistance Factor Design Method" has recently been developed from a research project sponsored by American Iron and Steel Institute. In this method, separate load and resistance factors are applied to specified loads and nominal resistance to ensure that the probability of reaching a limit state is acceptably small. These factors reflect. the uncertainties of analysis, design, loading, material properties and fabrication. They are derived on the basis of the first order probabilistic methodology as used for the development of the …

Latex-Concrete Overlays On Bridge Decks (I64, Mp 150 To West Virginia Line), James H. Havens, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

Visual field inspections and soundings were performed on latex concrete overlays on 24 bridges on I 64 between Milepoint 150 and the West Virginia state line. The inspections were conducted in response to a request from the Kentucky Department of Highways to determine if cracking problems in the overlays were related to workmanship or materials.

The field inspections revealed that most of the overlay crack problems were related to 1) reflection cracking caused by pre-existing fractures in underlying concrete bridge decks and 2) “pull-in” cracks in the overlay, caused by belated tyning of the bridge deck.

1985 Safety Belt And Child Safety Seat Usage Rates In Kentucky And Evaluation Of A Public Information Campaign, Kenneth R. Agent

Kentucky Transportation Center Research Report

Two objectives of the survey are summarized in this report. One was to establish 1985 safety belt and child safety seat usage rates in Kentucky and compare those to 1982, 1983, and 1984 rates. The other was to evaluate the effectiveness of public information campaigns as a means of increasing safety belt and safety seat usage rates.

Statewide usage rates in the 19 cities previously surveyed in 1982, 1983, and 1984 indicated that driver safety belt usage had increased to 9.2 percent in 1985 while the child safety seat and belt usage rate of 29.1 percent remained at the 1984 …

Traffic Trends And Their Relationship To Highway-Use Revenues, Jerry G. Pigman, Manouchehr Vaziri

Kentucky Transportation Center Research Report

With increasing concerns about the present level of highway funding, this study was initiated to investigate historical trends and to develop predictive methodologies for considering alternatives available for increasing highway revenues. Emphasis was placed on historical trends, and a data base of highway-related and socio-economic variables were prepared to document the relationship between these variables and highway-user revenues. A historical file of 37 variables was prepared for the period 1964 through 1984.

As a means of investigating future alternatives that will affect highway-user revenues, a series of nine equations or models were developed that represented historical data. Input data necessary …
