Evaluation Of Recovery In A Polluted Creek After Installation Of New Sewage Treatment Procedures, Robert A. Kuehne

KWRRI Research Reports

Response of Hickman Creek near Lexington, Kentucky to alleviation from serious sewage pollution was studied from January, 1973 through July, 1974. Wastes are now handled from an efficient secondary treatment facility and four sequential polishing lagoons before chlorination and discharge to West Hickman branch.

Physico-chemical tests gave no strong indication of residual pollution effects at the start of the study, approximately six months after the treatment facility opened. At low flow a slight oxygen sag, probably associated with algal growth in the lagoons, persists downstream from the outfall. Mean values for turbidity, nitrates and COD are somewhat higher at the …

Accidents Associated With Highway Bridges, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objective of this study was to identify those principal features of bridges which may be related to accident frequency and severity and to provide some further insights toward highway safety. Accident data from interstate and parkway (toll) routes and from primary and secondary systems were compiled and summarized. The major findings were:

1. Bridge-related accidents, particularly involving severe accidents, were significant percentages of the total accident experience on interstates and parkways.
2. There were fewer bridges per mile on the primary and secondary highway system and a lower percentage of bridge related accidents than on interstates and parkways.
3. The severity of …

First-Year Effects Of The Energy Crisis On Traffic In Kentucky (Rural Highways) [May 1975], Kenneth R. Agent, Donald R. Herd, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The Arab oil embargo in mid-October 1973 curtailed availability of gasoline. Fuel conservation measures resulted in reduced travel and decreased traffic speeds. On March 1, 1974, posted speed was set at 55 mph (24.6 m/s) on rural highways in Kentucky. Traffic volumes, speeds, and accidents for the rural highway during the period known as the "energy crisis" and its after effects were compared to the corresponding period a year earlier.

Traffic volumes began to decline in December 1973 and continued through September 1974. Total travel in the 12 months through November 1974 decreased by 2.3 percent; traffic increased by five …

Evaluation Of Raised Pavement Markers, Jerry G. Pigman, Kenneth R. Agent, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The purpose of this study was to evaluate the operational applicability of raised pavement markers and to determine their effectiveness with respect to brightness and durability. Seven different types of markers were evaluated. The primary application of markers in this study was as a supplement to lane lines. They were also used as a traffic control measure at lane drops, as delineation for hazardous curves, and as directional arrows.

Luminosity and durability were monitored for approximately one year. It was found that raised pavement markers can be a very effective method of roadway delineation. Markers evaluated had varying levels of …

Vehicle Noise Survey In Kentucky, Kenneth R. Agent, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

Individual noise measurements were obtained on 10,500 motor vehicles operating on Kentucky highways. The roadways were selected to represent varied geometric and environmental conditions and posted speed limits. Percentages of automobiles and trucks exceeding a given level of noise were determined. As expected, noise levels of trucks were significantly higher than for automobiles, and larger trucks produced higher noise levels than smaller trucks. For any vehicle type, noise increased with an increase in speed limit.

At-Grade Intersections Versus Grade-Separated Interchanges (An Economic Analysis Of Several Bypasses), Kenneth R. Agent

Kentucky Transportation Center Research Report

In an effort to reduce traffic in central business districts, bypasses have been built to provide through traffic a circumferential route and also to ease the burden of traffic in downtown areas. In many cases, though, bypasses have created a serious accident potential because they were built with at-grade intersections and no access control. This has led to commercial developments along the bypass and congestion at major intersections. When congestion increases at an intersection, traffic signals must be installed; this increases vehicle operating and time costs and creates a rear-end collision potential. In some cases, the bypass circumvents a relatively …

Engineering Data System For Bedrock Occurrences And Properties, D. J. Hagerty, Robert C. Deen, M. W. Palmer, C. D. Tockstein

Kentucky Transportation Center Research Report

The initial work plan included the development of a classification system based on index tests. An investigation of previous works in classification of rock on the basis of index tests showed that a variety of classification systems utilizing many different index tests had been developed. However, this survey showed that no generally applicable system had been developed and that little communication had been established between field investigators, facility designers, and those in charge of construction and maintenance of facilities. Therefore, the initial plan for work was modified to include the development of a comprehensive methodology for evaluation of rock. The …

Temperature Distributions In Asphaltic Concrete Pavements, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

The straight-line relationship between temperatures at a given depth and the surface temperatures combined with 5-day average air temperatures appears to be as valid for upper New York state and Arizona as for Maryland. The main differences were in the annual ranges and annual mean temperatures. The concept for estimating pavement temperature distributions appears to be valid and may be used with confidence for estimating pavement temperatures at all latitudes and longitudes.

Pedestrian Accidents In Kentucky: 1972-1973, Charles V. Zegeer

Kentucky Transportation Center Research Report

Pedestrian accident data in Kentucky were analyzed for 1972 and 1973 on a rural, urban, and statewide basis. Results showed that about 1500 pedestrian accidents occur in Kentucky each year and cost over $11 million. About 30 percent of pedestrian accidents in rural areas and 4 percent in urban areas are fatal. Although about 78 percent of Kentucky's pedestrian accidents occur in urban areas, over 62 percent of the pedestrian fatalities occur in rural areas.

Specific characteristics of pedestrian accidents were identified and related to human, environmental, and time factors. Highway and street improvements and safety programs generally considered to …

The co-ordinated evaluation system detailed herein provides guidelines for implementation of an extensive system of data storage and retrieval to …

Effect Of Pavement Texture On Traffic Noise, Kenneth R. Agent, Charles V. Zegeer

Kentucky Transportation Center Research Report

Tire noise is one of the primary sources of highway noise, particularly at high speeds. Different types of road surfaces generate different noise levels. Noise data were collected on eight different surface types found in Kentucky. Noise measurements were made using a reference car, and noise recordings were obtained from the traffic stream. A reference truck was used for one test. It was found that portland cement concrete; Class I, Type A and A(Modified) bituminous concrete; chip seals; and open-graded, plant-mix seals were more or less "normal" surfaces in regard to generated noise. Sand-asphalt and Kentucky rock asphalt surfaces were …

Process Control Of Activated Sludge Treatment, Phase Ii, Richard I. Kermode, Robert W. J. Brett, Joseph D. Pault Jr.

KWRRI Research Reports

Material balances on substrate and microorganisms were derived in conjunction with various mixing configurations thought to accurately describe the activated sludge process. These models include the completely mixed with bypass, plug flow, and plug flow with bypass. Two sets of kinetic mechanisms for substrate utilization and bacterial growth were employed.

A feed forward controller was designed from linear approximations of the material balances derived in the completely mixed with bypass mixing model. Utilizing frequency response methods, the controller was found essentially identical to a completely mixed modeled controller developed in a prior investigation.

Through computer simulation the controller's effectiveness was …

Stochastic Simulation Of Daily Rainfall, David M. Allen, C. T. Haan, Don Linton, Jim Street, David Jordan

KWRRI Research Reports

The design of many water resources projects requires knowledge of possible long-term rainfall patterns. In this project a stochastic model based on a first order Markov chain was developed to simulate daily rainfall at a point. The model is applicable to any point in Kentucky (and other areas with similar rainfall patterns).

The model in its present form is useful in providing rainfall inputs into hydrologic models for designing water supply facilities and other water resources systems. The model uses historical rainfall data to estimate the Markov transitional probabilities. A separate matrix is estimated for each month of the year. …

Deflection Behavior Of Asphaltic Concrete Pavements, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Deflection responses of a series of experimental test sections were obtained layer by layer during construction, upon completion of construction, and subsequent to construction. Deflections were obtained by use of Benkelman beams, the Road Rater, and the Dynaflect. Test results from one location within each test section were analyzed to determine which relationships were, or were not, meaningful. This was done as a pilot study and as a preliminary step toward final analysis of the data bank. The analyses are presented in this report.

It is intended to test the utility of anthropological method and concept in evaluating and explicating sociocultural impact, and in addition to check hypotheses concerning importance of impact on social and economic areas of culture of the persons to be displaced, on their emigration patterns, and their …

The Use And Legal Significance Of The Mean High Water Line In Coastal Boundary Mapping, Richard C. Ausness, Frank E. Maloney

Law Faculty Scholarly Articles

The effect of unplanned and ill-conceived land use development on the coastal ecology has been well documented in recent years. Recognizing the need for more effective governmental control in this area, a number of state legislatures have enacted statutes to protect the coastal environment and encourage the orderly development of coastal resources. These efforts have received the support of the federal government as well.

Determination of coastal boundaries is essential to the development of an effective coastal zone management program. In general such boundaries represent the intersection of the shore with a particular tidal elevation. However, the demarcation of coastal …

Hydraulic And Flow Studies Related To Sediment Transport, Kentucky River, Kentucky, Bruce R. Moore, Michael R. Short, Thomas Wachs

KWRRI Research Reports

This study related the conditions of flow and channel shape to distribution of sediment types in the Kentucky River. Seven distinct types of sediment association were delineated and these have a regular pattern of distribution influenced by the presence of navigation locks and dams. The most suitable locations for commercial extraction of bed material were clearly indicated and the variations of sand size delineated by the study. The irregular discharge pattern of the stream indicates potential problems in the disposal of solid waste pollutants.

A remeasurement of the dredge hole in the Ohio River indicated a continuation of the same …

Optimal Highway Safety Improvement Investments By Dynamic Programming [Dec. 1974], Jerry G. Pigman, Kenneth R. Agent, Jesse G. Mayes, Charles V. Zegeer

Kentucky Transportation Center Research Report

The process of determining which projects to implement under a given budget, and which to defer until later, is central to the planning and management of highway systems. With a limited budget for construction, maintenance, and safety improvements, investments which will produce the optimal benefits must be chosen. This is often impossible to accomplish without the aid of a computer because of the complexity of the problem. Dynamic programming has been tested and verified as an efficient method for selecting priority projects to derive maximum benefits. The applicability of dynamic programming to the safety improvement program is demonstrated in this …

Voidless Concrete Mixtures For Bridge Decks, Assaf S. Rahal

Kentucky Transportation Center Research Report

The purpose of this study was to modify concrete mix-design formulas to supplant all water over and above that needed for hydration with a non-evaporable material -- thus producing a no-void concrete. It was adjudged that a water-cement ratio of 0.244 would be practical for hydration of the cement. Several polymeric materials, asphalts, and oils were used to replace the excess mixing water. Success was achieved using two latexes and one epoxy. The use of these materials in concrete resulted in improved strength, reduction of air voids and permeability, and enhancement of resistance to corrosive chloride salts.
