Creating Opportunities or Building Barriers

Megan Beach & Karin Ann Lewis
Placement tests are an integral aspect of the first-year experience. As policymakers seek to raise high school standards and ensure that more students graduate prepared for the academic rigor of college, placement tests are being called upon to serve new purposes. Placement tests are touted for their ability to predict college success, but do these tests really measure student attainment of specific college readiness skills? How can they fit with or contribute to institutional initiatives?

Evaluation Plan for the Ticketing Aggressive Cars and Trucks (TACT) Program in Kentucky

Eric R. Green
Kentucky State Police Division of Commercial Vehicle Enforcement in cooperation with Federal Motor Carrier Safety Administration (FMCSA) has started a concentrated education and enforcement campaign in an effort to increase the safety and awareness of drivers around commercial vehicles.

Early Stage Benefit Cost Analysis for Estimating Economic Impacts

Doug Kreis, Brian Howell & Lenahan O'Connell
This study reviewed the various software packages and other methods in use for estimating the economic impacts of proposed transportation projects. A total of 13 economic software packages were examined as potential applications in meeting KYTC’s business needs. It was determined that only the TREDIS model from the Economic Development Research Group, Inc. or the TranSight model from Regional Economic Models, Inc. could potentially meet Kentucky’s needs as defined in the project.

Cross-Sector Partnerships and Public Health

Lee Johnston & Diane Finegood
Over the past few decades, cross-sector partnerships that include the private sector have become an increasingly accepted practice in public health, particularly in efforts to address infectious disease in low and middle income countries. Now they are becoming a popular tool in efforts to reduce and prevent obesity and the epidemic of non-communicable disease. Partnering with business presents a means of acquiring resources, as well as opportunities to influence the private sector toward more healthful...

Performance of Pyrament Cement Concrete in a Highway Bridge Deck

David Q. Hunsucker & Michael D. Stone
Pyrament Blended Cement (PBC) is a high performance cement that was developed by Lone Star Industries. Concrete that is made with PBC is rapid setting, has high strength and low permeability. The Kentucky Transportation Cabinet chose to use PBC concrete in a lull·depth bridge deck. The objectives of this study were to evaluate the construction and performance of a full-depth bridge deck constructed of PBC concrete and to compare the data obtained to historical construction...

Impacts of the Extended-Weight Coal Haul Road System

Jerry G. Pigman, Joseph D. Crabtree, Kenneth R. Agent, R. Clark Graves & John A. Deacon
The Extended-Weight Coal Haul Road System, created by the Kentucky Legislature in 1986, consists of all roads which carry over 50,000 tons of coal in a calendar year. Trucks hauling coal on this system are authorized to exceed normal weight limits through the payment of an annual decal fee. A research study was initiated in July of 1992 to analyze the impacts of the extended-weight system. Analyses in this report are based on the following:...

The objectives of this study were to: a) evaluate and analyze motorcycle crashes and b) identify the causes and potential countermeasures to reduce the number and severity of the crashes. The...

Construction Training for the Current and Next Generation of Technicians

Paul M. Goodrum & Dong Zhai
Technicians are a vital component to the success of any roadway projects. Unfortunately, the Kentucky Transportation Cabinet (KYTC) is experiencing significant shortages of technicians among all aspects of construction and maintenance. Training and developing the adequate numbers of qualified technicians is a substantial endeavor that requires a comprehensive examination of the adequacy of current training program versus the anticipated skill needs of technicians on future projects. Two questionnaires were developed to identify this gap. One...

Development of Performance Measures and Revenue Projections for State Highway Transportation Systems

Dwight V. Denison, Christopher Jepsen, Bryan Gibson, Candice Wallace & Doug Kreis
The purpose of this report is to develop a pilot model that demonstrates how metrics can be identified and reported in a “dashboard” format to be used to monitor the progress of a transportation system in efficiently meeting established priorities. An additional component of this research is to examine the revenue implications of a shift away from the traditional funding mechanism on the financial viability of state transportation systems.
