The over representation of teenage drivers in traffic collisions has been a cause of concern and the basis for the recent graduated license legislation. A subcommittee of the Safety Management System has the objective of improving teenage driver safety through development and implementation of education and training programs. The objective of this study was to obtain information on current and desired traffic safety related programs for high schools. A survey was sent to all high schools. Information was obtained from 189 of 432 schools. Current activity in the area of traffic safety was summarized. The activity with the most participation …

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

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 …

Traffic Flow And Safety Evaluation Of Fayette County Schools, Samantha S. Jones, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

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 …

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, …

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.
