Energy Absorption Devices, James H. Havens

Kentucky Transportation Center Research Report

An ironic consequence of modern highways has been the emergence of new types of accidents. Recent investigations (1) have shown that "running off the road" may be the largest, single cause of fatalities on limited access, multilane roads. According to the 1967 Report of the Special AASHO Traffic Safety Committee ("Yellow Book") (2) the rate of accidents in gore areas is approximately four times that of ran-off-the-road accidents at other locations. Gore areas which are not or cannot be modified to provide favorable terrain and unobstructed recovery zones have been recognized as misfits in the environs of the highway. Crash …

The Relation Between Soil Characteristics, Water Movement And Nitrate Contamination Of Ground Water, Grant W. Thomas, Matthew Mcmahon

KWRRI Research Reports

Soils from several areas in Kentucky were placed in columns and leached with Ca(NO₃)₂. Subsoils high in iron oxide were found to retard the leaching of nitrate very significantly. In other soils, the nitrate moved through as fast as or slightly faster than the water.

Field application of nitrogen to corn was most efficient when done in the spring or summer near the time that the corn takes it up. The one exception to this was a red soil, where fall application of nitrogen resulted in little loss due to the retarding effect mentioned in the …

Accident And Economic Analyses Of Access Control On Several Bypasses, Kenneth R. Agent

Kentucky Transportation Center Research Report

In an effort to relieve congestion on urban streets, bypasses have been built to provide through traffic a route by which the downtown areas can be avoided.

In many cases, though, bypasses have created a serious accident potential because they were built with at-grade intersections and no access control. This leads to commercial developments along the bypass and congestion at major intersections. Bypasses were constructed in this manner because of the high initial cost involved in building a bypass with access control and grade-separated interchanges. There is, therefore, a need to determine if the accident cost savings, along with time …

Accidents On Rural Interstate And Parkway Roads And Their Relation To Pavement Friction, Cass T. Napier

Kentucky Transportation Center Research Report

Friction measurements were made with a skid trailer at 70 mph on 820 miles of rural, four-lane, controlled-access routes on the interstate and parkway systems in Kentucky. These facilities were subdivided into test sections and half-mile sites. Accident experience, friction measurements and traffic volumes were obtained for each subdivision.

The expression of accident occurrence which correlated best with skid resistance was wet-surface accidents per 100 million vehicle miles. There was a definite trend exhibiting a rapid decrease of accidents with increasing Skid Number (70 mph) to 26 ± 1; thereafter, with increasing Skid Numbers, the rate of decrease was considerably …

Skid Resistance Of Pavements [Sept. 1972], Rolands L. Rizenbergs, James L. Burchett, Cass T. Napier

Kentucky Transportation Center Research Report

Standard pavement types and experimental surfaces on roads throughout Kentucky were evaluated in terms of skid resistance and effects of traffic, wear, and polishing. Friction-vs-speed gradients and the relationships between locked-wheel and incipient friction were determined. Asphaltic concrete pavements on high-speed, four-lane roads were found to be significantly more skid resistant than on two-lane highways and somewhat more skid resistant than concrete surfaces (especially those containing calcareous gravel aggregates). Sand-asphalt surfaces containing significant proportions of limestone sands showed inadequate level of friction for the traffic sustained. Several experimental sand asphalts without limestone sands exhibited greater skid resistance; Kentucky rock asphalt …

Application Of Gravity And Intervening Opportunities Models To Recreational Travel In Kentucky, Kenneth D. Kaltenbach

Kentucky Transportation Center Research Report

Weekend outdoor recreational travel has a major impact on the highway network in Kentucky. Data from a previous study (1) indicate that the number of people visiting 42 typical Kentucky outdoor recreation areas on an average summer Sunday in 1970 was approximately 260,000. Most of these 42 areas, by virtue of their outdoor nature, are located in rural settings. Most have access to major arterial highways only by means of narrow, low standard rural roads. Traffic generated by the recreation areas and their associated developments severely strains these secondary access highways and places a significant additional load on the rural …

Hydraulic And Sediment Transport Studies In Relation To River Sediment Control And Solid Waste Pollution And Economic Use Of The By-Products, Bruce R. Moore, Michael R. Short

KWRRI Research Reports

The distribution of sediments and conditions of transport were studied in the Kentucky, Big Sandy and Ohio Rivers. The sand and coal were in transport at different flow velocities for the rivers and the deposition of these sediments was a direct function of the flow conditions at a particular locality.

The flow conditions of transport of the sediments were studied in flumes as were the hydraulic conditions in model dredge holes to determine the feasibility of trapping sediment. The conditions of scour and fill were also established and compared with known conditions in a dredge hole in the Ohio River. …

Impact Of A Proposed Reservoir On Local Land Values, Philip Drucker, Charles R. Smith, Allen C. Turner

KWRRI Research Reports

This project was designed to study the impact of private preconstruction land acquisition in a Central Kentucky area in which a flood-control dam and reservoir impoundment is planned. The research design was built around use of anthropological concepts and research techniques. By these means it was possible to analyze the perceived values of land to traditionalist residents, among which social and economic security concepts are paramount. Recent land purchases, locally believed to have been made chiefly by "outsiders," (urbanites from nearby Louisville), at prices out of line in terms of local agricultural worth, has been extremely unsettling contributing to the …

Skid Resistance Of Pavements [July 1972], Rolands L. Rizenbergs, James L. Burchett, Cass T. Napier

Kentucky Transportation Center Research Report

Standard pavement types and experimental surfaces on roads throughout Kentucky were evaluated in terms of skid resistance and effects of traffic, wear, and polishing. Friction-vs-speed gradients and the relationships between locked-wheel and incipient friction were determined. Class I bituminous pavements on high-speed, four-lane roads were found to be significantly more skid resistant than on two-lane highways and somewhat more skid resistant than concrete surfaces (especially those containing calcareous gravel aggregates). Sand-asphalt surfaces containing significant proportions of limestone sands showed inadequate level of friction for the traffic sustained. Several experimental sand asphalts without limestone sands exhibited greater skid resistance; Kentucky rock …

High-Intensity Reflective Materials For Signs, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The intuitive need for improved sign legibility has increased through the years as traffic volumes, speeds and roadway designs have advanced. Because of increased traffic volumes, low-beam headlight illumination at night has become more imperative. Signs are being located farther from the travelled lanes; higher speeds are requiring messages to be more legible at greater distances (for driver decision and response). Recent studies have indicated that even Engineering Grade (2200 and 3200 Series) Scotchlite or materials designated as Type I, Class A in S.P. No. 89-A, may be inadequate for some signing situations. Signs may be made larger and(or) incorporate …

Digital Computer Modeling Of Limestone Groundwater Systems, John Thrailkill, David P. Beiter

KWRRI Research Reports

Because limestone groundwater flows mainly In discrete openings, limestone aquifers are fundamentally different from aquifers In granular rocks. A digital computer program which simulates flow in a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west-central Kentucky.

A reasonably good fit between observed parameters of the aquifer and those calculated were obtained under assumed conditions of both laminar and turbulent now In the aquifer. The Indicated gross permeablllty of the aquifer is 5600 melnzers with an assumed aquifer thickness of 100 feet. The location and discharge of springs along the streams bounding …

From Caveat Emptor To Strict Liability: A Review Of Products Liability In Florida, Richard C. Ausness

Law Faculty Scholarly Articles

Since the doctrine of caveat emptor gave way to a more enlightened response, the courts have struggled to place the law of products liability on a proper doctrinal foundation. Negligence, implied warranty, and strict liability have been used, but as yet no universally accepted theory has emerged. In light of this problem this article will trace the development of seller's liability in Florida. Special emphasis will be placed upon implied warranty; in addition, the relationship between existing Florida case law, strict liability under the Restatement of Torts and the warranty provisions of the Uniform Commercial Code will be examined.

KWRRI Research Reports

The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring …
