Understanding And Efficiently Managing Right-To-Take Challenges In Kentucky, Pam Clay-Young, Steve Waddle, Bryan Gibson

Kentucky Transportation Center Research Report

Executive Summary

Kentucky constitutional and statutory law requires that a fair process be in place to let a property owner challenge a condemnor’s right to acquire private property, including a right to appeal the initial decision. Property acquired by a condemnor must be for public use, and property owners have the right to an immediate and expedited hearing on right-to-take. Two of these requirements will remain in place regardless of statutory revisions: the requirement that property must be needed (i.e., not arbitrary) for public use, and the right to one appeal. Only an amendment(s) to the Kentucky Constitution would alter …

Integrated Freight Network Model: A Gis-Based Platform For Transportation Analyses, Ted H. Grossardt, John Ripy, Benjamin L. Blandford, Michael Shouse

Kentucky Transportation Center Research Report

The models currently used to examine the behavior transportation systems are usually modespecific. That is, they focus on a single mode (i.e. railways, highways, or waterways). The lack of integration limits the usefulness of models to analyze the intermodal movement of freight. This project developed a GIS-based model of the three primary surface modes as well as intermodal connections. The resulting Integrated Freight Network Model (IFNM) accommodates highly detailed about shipping costs, transfer costs, traffic volumes (including non-freight auto traffic), and network interconnectivity properties. As a proof of concept, the research team conducted an exploratory analysis that asked what the …

Culture, Justice And The Arnstein Gap: The Impact Of Structured Public Involvement On U.S. Transportation Infrastructure Planning And Design, Keiron Bailey, Ted H. Grossardt

Kentucky Transportation Center Faculty and Researcher Publications

Enormous quantities of public money are spent on transportation infrastructure (TI). According to the Bureau of Transportation Statistics this infrastructure spend in the U.S. amounted to almost $90 billion in 2001. In most political spheres, when public money is spent, the public demands a measure of accountability. The dimensions of this accountability depend on the character of the political system that funds TI. In most participatory democracies, ultimate accountability is exercised through a balloting system that ensures elected officials represent, to some degree, stakeholder views and preferences. However, despite enormous expenditure of public monies on TI, this type of accountability …

Assessment Of The 1997 Commodity Flow Survey For State-Level Freight Transportation Planning, Darren M. Scott

Kentucky Transportation Center Research Report

Urban travel demand modeling in the United States has a rich history in both practice and academic research. The same cannot be said, however, of freight demand modeling despite the intermodel planning requirements of IS TEA and TEA21. In most instances, agencies responsible for state transportation planning (e.g. Kentucky Transportation Cabinet) have applied, in a limited way, the methodology developed for urban travel demand modeling (i.e., Urban Transportation Modeling System or UTMS 1) to the freight arena (see, for example, Black 1997). Obviously, this methodological similarity implies that the fundamental data requirements for both types of demand modeling are also …
