Inland Waterway Operational Model & Simulation Along The Ohio River, Doug Kreis, Roy E. Sturgill, Brian K. Howell, Christopher W. Van Dyke, D. Stephen Voss
Inland Waterway Operational Model & Simulation Along The Ohio River, Doug Kreis, Roy E. Sturgill, Brian K. Howell, Christopher W. Van Dyke, D. Stephen Voss
Kentucky Transportation Center Research Report
The inland waterway system of the U.S. is a vital network for transporting key goods and commodities from the point of production to manufacturers and consumers. Shipping materials via the inland waterways is arguably the most economical and environmentally friendly option (compared to hauling freight by trains or railways). Despite the advantages the inland waterways enjoys over competing modes, key infrastructure – such as locks and dams, which help to control water levels on a number of rivers and make navigation possible – is declining. Limited funds have been allocated to make the necessary repairs to lock and dam facilities. …
Multi-Barge Flotilla Impact Forces On Bridges, Peng Yuan, Issam E. Harik, Michael T. Davidson
Multi-Barge Flotilla Impact Forces On Bridges, Peng Yuan, Issam E. Harik, Michael T. Davidson
Kentucky Transportation Center Research Report
The current AASHTO equations for barge impact loads are based on scale models of barges, and may not accurately predict impact loads on bridge piers. The results of this study produce more realistic flotilla impact design loads, potentially leading to a reduction in construction costs of bridges over navigable waterways. The objectives of this study are: (1) To conduct theoretical finite element analysis on various types of flotillas impacting bridge piers. The flotillas and the respective barges will be of the type commonly traversing Kentucky’s waterways; and (2) To generate design equations for barge/flotilla impact loads. The study concludes the …
Equivalent Barge And Flotilla Impact Forces On Bridge Piers, Peng Yuan, Issam E. Harik
Equivalent Barge And Flotilla Impact Forces On Bridge Piers, Peng Yuan, Issam E. Harik
Kentucky Transportation Center Research Report
Bridge piers located in navigable inland waterways are designed to resist impact forces from barges and flotillas in addition to other design considerations (e.g., scour, dead and live loads, etc.). The primary design tool for estimating these forces is the AASHTO Guide Specification which provides a simple hand calculation method for determining an “equivalent impact force”. The simplicity comes at a cost of excluding the effect of the pier shape, impact duration, and interaction between barges in a flotilla. The objective of this report is to present a hand calculation method for determining barge or flotilla equivalent static impact forces …
The Dayton Its Demonstration Project: Simulating Existing Conditions, Jill A. Swaynos, Nikiforos Stamatiadis
The Dayton Its Demonstration Project: Simulating Existing Conditions, Jill A. Swaynos, Nikiforos Stamatiadis
Kentucky Transportation Center Research Report
The Miami Valley Regional Planning Commission is incorporating an Advanced Traveler Information System to alleviate real-time traffic problems associated with special events at the Ervin J. Nutter Center of the Wright State University. This study of the existing conditions is part of the evaluation plan and addresses two tasks: 1) documentation of the existing conditions; and 2) definition of measures of effectiveness. The existing conditions were depicted with the use of a computer simulation software package, Traffic Software Integrated System and separate scenarios were modeled for three existing conditions: ingress and egress for a special event and a major shopping …
Conversion Of New Circle Road To A Limited Access Highway, Steven M. Henderson, Nikiforos Stamatiadis
Conversion Of New Circle Road To A Limited Access Highway, Steven M. Henderson, Nikiforos Stamatiadis
Kentucky Transportation Center Research Report
The objectives of this study were to first evaluate the existing traffic conditions along the NE part of New Circle Road and investigate the use of unconventional left turn treatments, as well as other access restrictions to improve the operating conditions of New Circle Road. The alternatives examined include a do-nothing alternative, the addition of one through lane per direction, the use of median U-turns at various locations, and combinations of them. Restrictive left turn strategies proved to be a more successful tool for traffic management on New Circle Road than simply adding a lane in each direction. Using median …
