Improvement Of Fatal Crash Analysis And Follow-Up, William Nicholas Staats, Jerry G. Pigman, Kenneth R. Agent, Paul A. Ross

Kentucky Transportation Center Research Report

Executive Summary

Fatalities resulting from traffic crashes in Kentucky increased from a low of 638 in 2013 to 834 in 2016 (a 31% increase), and there is not a full understanding of the underlying causes for this trend. This study analyzes fatal crashes using data from both Kentucky’s crash reports and the National Highway Traffic Safety Administration’s (NHTSA) Fatal Accident Reporting System (FARS) to identify countermeasures to combat increasing fatal crash rates. In addition, this study compares Kentucky’s crash reports to the fatal crash data in FARS to identify data inconsistencies and recommend procedures to eliminate these inconsistencies.

Kentucky Transportation Center Research Report

Executive Summary

This report documents an analysis of traffic crash data in Kentucky for the years of 2013-2017. A primary objective of this study was to determine average crash statistics for Kentucky highways. Rates were calculated for various types of highways and for counties and cities. Difference criteria were used for exposure.

Average and critical numbers and rates of crashes were calculated for various types of highways in rural and urban areas. These rates used crashes identified on highways where traffic volumes were available. Improved methods of identifying crash locations have resulted in higher rates for the last couple of …

Us 31w Jefferson County Pavement Surface Treatment Evaluation, Tim C. Scully Jr.

Kentucky Transportation Center Research Report

Reflective cracking inevitably occurs when asphaltic concrete (AC) is placed over an existing unfractured Portland cement concrete (PCC) pavement. However, manufacturers state their products will mitigate reflective cracking, therefore extending the pavement life cycle.

To evaluate the performance of each manufacturer’s product, an experimental test section consisting of a southbound and northbound segment was established on US 31W in Louisville, Kentucky. The funding for this project will help track the performance of each product from the construction phase through the long-term monitoring phase. Hall Construction performed all work.

Developing Knowledge Management Strategies, Bryan Gibson, Candice Y. Wallace, Steven Douglas Kreis

Kentucky Transportation Center Research Report

Retirements and other staff changes have led to a loss of institutional knowledge across public agencies. These changing workforce dynamics have highlighted the study of knowledge management, and how organizations can best retain their core knowledge bases. Key to understanding knowledge management is how organizations have approached the issue and the most effective methods and processes they have used to retain, store, and disseminate knowledge. Part of the knowledge management discussion includes core competencies, or what basic knowledge and skills are essential to an organization’s mission. Also, considering the impacts of outsourcing on public employment, is another key to understanding …
