Use Of Audible Pedestrian Signals, Kenneth R. Agent
Use Of Audible Pedestrian Signals, Kenneth R. Agent
Kentucky Transportation Center Research Report
Audible pedestrian signals are a device used to provide additional traffic control at signalized intersections to aid visually impaired pedestrians. An objective of this study was to determine the status of the use of this device and investigate possible guidelines for possible future installations of audible pedestrian signals in Kentucky. Another specific objective was to investigate the need for such signals at a number of intersections at the University of Kentucky.
The study showed that audible pedestrian signals can be used to supplement the standard pedestrian signals. However, their use must be limited to intersections with a demonstrated need and …
Visual Inspection Of New Ramp Pavement At Bluegrass Airport Lexington, Kentucky, David L. Allen
Visual Inspection Of New Ramp Pavement At Bluegrass Airport Lexington, Kentucky, David L. Allen
Kentucky Transportation Center Research Report
Personnel from the Kentucky Transportation Center performed a visual inspection of newly constructed ramp pavement at the Bluegrass Airport in Lexington, Kentucky. The inspection was conducted in May, 1996 at the request of airport engineers. The inspection revealed a number of concrete apron slabs that had cracked. Attempts had been made (apparently by the contractor) to seal the cracks by epoxy injection. The visual inspection indicated that the epoxy may not have been performing as hoped, and that some of the cracks did not appear to be sealed. As a result, it was decided to obtain cores of the cracked …

Analysis Of Traffic Accident Data In Kentucky (1991-1995), Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
This report includes an analysis of traffic accident data in Kentucky for the years of 1991 through 1995. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical numbers and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.
The other primary objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety …

In cooperation with Fayette County Schools, an evaluation of traffic flow and safety was conducted at school sites in Fayette County. The purpose of this evaluation was to eliminate potential safety risks currently existing at a number of schools and to reduce traffic congestion in and around school properties.
The evaluation was completed in two main phases. First, each school in the district was asked to respond to a survey questionnaire. Second, six schools were identified by Fayette County Schools as having traffic flow or safety problems that could benefit from detailed evaluation. The responses to the survey questionnaire were …
Evaluation Of Portable Retroreflectometers, Kentucky Transportation Center
Evaluation Of Portable Retroreflectometers, Kentucky Transportation Center
Kentucky Transportation Center Research Report
Portable retroreflectometers have been used to compare the reflectivity of the various pavement marking materials. The Mirolux 12 has been used to collect reflectivity data for the products tested for the National Transportation Product Evaluation Program (NTPEP). The Mirolux 12 docs not have a 30 meter geometry, and there has been a desire to explore the possibility of using a retroreflectometer which has a 30 meter geometry which may better simulate the view of a driver. The objective of this report is to compare data taken with the Mirolux 12 and two other portable retroflectometers having the 30 meter geometry.

1996 Safety Belt Usage Survey And Evaluation Of Effectiveness In Kentucky, Kenneth R. Agent
Kentucky Transportation Center Research Report
The objective of this study was to establish 1996 safety belt and child safety seat usage rates in Kentucky. The 1996 survey documents the continuing results from enacting a statewide mandatory safety belt law in 1994. Data were collected at 100 sites and combined based on vehicle miles travelled for a given type of highway, rural or urban location, and county population category. Also included in the report is an analysis of accident records evaluating the effectiveness of safety belts.
The data show that the decrease in the usage rate which occurred in 1995 after the dramatic increase in 1994, …

Kentucky Transportation Center Research Report
This report summarizes the results of data collected as part of the 1995 field and laboratory evaluations of pavement marking materials for the National Transportation Product Evaluation Program (NTPEP). The purpose of the NTPEP is to pool the professional and physical resources of the individual participating AASHTO member departments and to focus those resources to test materials of common interest in order to improve cost-effectiveness.
The type of testing performed under the NTPEP provides information that will be used to evaluate the acceptability of materials and to compare the performance of similar materials. The NTPEP also provides industry with a …
Evaluation Of Edge Drains On Interstate 64 Fayette, Scott, And Woodford Counties, L. John Fleckenstein, David L. Allen, Brad W. Rister
Evaluation Of Edge Drains On Interstate 64 Fayette, Scott, And Woodford Counties, L. John Fleckenstein, David L. Allen, Brad W. Rister
Kentucky Transportation Center Research Report
This report documents findings of the investigation of edge drains and their associated outlets on Interstate 64 from Milepost 65 to Milepost 75.6 in Fayette, Scott, and Woodford Counties. The study was initiated due to significant amounts of water and fines coming up through the AC surface. State and Federal Officials were concerned that possible failures in the edge drains were causing pumping and staining which will ultimately lead to premature pavement failure. Several factors appear to be contributing to the staining and pumping at the surface. These factors are discussed in the report.

The basis of the accident reduction factors developed in this study is a survey of states and a review of literature. The recommended reduction factors are presented in a table which lists the percent reduction in all accidents or specific types of accidents for given types of improvements.
Evaluation Of Edge Drains On I-81, In Roanoke, Virginia, L. John Fleckenstein, David L. Allen
Evaluation Of Edge Drains On I-81, In Roanoke, Virginia, L. John Fleckenstein, David L. Allen
Kentucky Transportation Center Research Report
This report documents findings of the investigation of five different brands of panel edge drains installed in a test section along Interstate 81 in Roanoke, Virginia, from Milepost 154.148 to Milepost 156.11. Findings from this study indicated that closed core edge drains (Multi-Flow, Advanedge) are less likely to become damaged or distressed than the more open core drains (Contech, Akwadrain, Hydraway). Typical distress found in the more open cores was rolling over of the top row of support columns, fabric intrusion between support columns, and rolling up of the bottom row of support columns.

Evaluation Of Edge Drains On Pennyrile Parkway Webster County, L. John Fleckenstein, David L. Allen
Kentucky Transportation Center Research Report
This report documents findings of the investigation of pipe edge drains and outlets on the Pennyrile Parkway from Milepost 60.476 to Milepost 65.305 in Webster County. The study was initiated due to concerns from District 2 personnel that possible failures in the edge drains were causing pavement distress along the right wheel path. Findings from this study indicated that approximately 40 percent of the 123 edge drain outlets were less than 50 to 60 percent open. The round perforated pipe edge drain appeared to be in excellent condition, including the integrity of the pipe and the filter material. The sand …
