The Use Of Cell Phone Network Data In Traffic Data Collection And Long-Haul Truckshed (Geographic Extent) Tracking, Ming-Heng Wang, Steven D. Schrock, Nate Vander Broek, Thomas Mulinazzi
Mid-America Transportation Center: Final Reports and Technical Briefs
This study analyzed the potential of cell phone positioning techniques in freight truck data collection and long-haul truckshed (geographic extent) tracking. Freight truck identification and tracking algorithms were developed by means of cell phone network data and the established freight truck analysis GIS, to recognize freight trucks and determine their geographic extent (trucksheds). A case study was conducted to illustrate the truckshed tracking process and verify the tracking results from the cell phone network. Cell phones leaving from the test logistics distribution center were tracked and classified based on the developed tracking algorithms. The case study also demonstrated the processes …

Structural Topology Optimization: Moving Beyond Linear Elastic Design Objectives, James K. Guest, Reza Lotfi, Andrew T. Gaynor, Mehdi Jalalpour
Civil and Environmental Engineering Faculty Publications
Topology optimization is a systematic, free-form approach to the design of structures. It simultaneously optimizes material quantities and system connectivity, enabling the discovery of new, high-performance structural concepts. While powerful, this design freedom has a tendency to produce solutions that are unrealizable or impractical from a structural engineering perspective. Examples include overly complex topologies that are expensive to construct and ultra-slender subsystems that may be overly susceptible to imperfections. This paper summarizes recent tools developed by the authors capable of mitigating these shortcomings through consideration of (1) constructability, (2) nonlinear mechanics, and (3) uncertainties.

2012 Nebraska Groundwater Quality Monitoring Report
2012 Nebraska Groundwater Quality Monitoring Report
Nebraska Department of Environmental Quality: Reports
The 2001 Nebraska Legislature passed LB329 (Neb. Rev. Stat. §46-1304) which, in part, directed the Nebraska Department of Environmental Quality (NDEQ) to report on groundwater quality monitoring in Nebraska. Reports have been issued annually since December 2001. The text of the statute applicable to this report follows: “The Department of Environmental Quality shall prepare a report outlining the extent of ground water quality monitoring conducted by natural resources districts during the preceding calendar year. The department shall analyze the data collected for the purpose of determining whether or not ground water quality is degrading or improving and shall present the …

Onsite Use Of Recycled Asphalt Pavement Materials And Geocells To Reconstruct Pavements Damaged By Heavy Trucks, Jie Han Ph.D., P.E., Bhagaban Acharya, Jitendra K. Thakur, Robert Parsons Ph.D., P.E.
Onsite Use Of Recycled Asphalt Pavement Materials And Geocells To Reconstruct Pavements Damaged By Heavy Trucks, Jie Han Ph.D., P.E., Bhagaban Acharya, Jitendra K. Thakur, Robert Parsons Ph.D., P.E.
Mid-America Transportation Center: Final Reports and Technical Briefs
Asphalt pavements deteriorate with traffic (especially heavy trucks) and time. Maintenance and overlaying may solve minor to medium pavement distress problems. When the condition of a pavement becomes badly deteriorated, reconstruction of the pavement may become an economic and feasible solution. Reconstruction of a pavement requires removal of pavement surfaces. On-site use of recycled asphalt pavement materials has obvious benefits from economic, to environmental, to sustainability points of view. One attractive option is to use recycled asphalt pavement (RAP) materials as base courses with a thin new overlay. However, RAP has its limitations; for example, it creeps under a sustained …

Mid-America Transportation Center: Final Reports and Technical Briefs
For this study, a novel optical fiber sensing system was developed and tested for the monitoring of corrosion in transportation systems. The optical fiber sensing system consists of a reference long period fiber gratings (LPFG) sensor for corrosive environmental monitoring and a LPFG sensor coated with a thin film of nano iron and silica particles for steel corrosion monitoring. The environmental effects (such as pH and temperature) are compensated by the use of the reference LPFG sensor. The sensor design, simulation, and experimental validation were performed in this study to investigate the feasibility of the proposed sensing system for corrosion …
Offset Right-Turn Lanes For Improved Intersection Sight Distance Final Report, Karen Schurr P.E., Timothy J. Foss Jr.
Offset Right-Turn Lanes For Improved Intersection Sight Distance Final Report, Karen Schurr P.E., Timothy J. Foss Jr.
Mid-America Transportation Center: Final Reports and Technical Briefs
Many transportation agencies have started using offset right-turn lanes (ORTLs) at two-way stop-controlled intersections in the hope of improving driver safety by providing intersection departure sight distance triangles that eliminate through roadway right-turning vehicle obstructions. Currently, there are no specific geometric guidelines for key three-dimensional characteristics to allow drivers the optimal use of laterally-shifted right-turn lanes. Results of driver behavior studies at existing locations of offset right-turns lanes indicate that drivers are not performing as expected at parallel-type ORTLs, rendering its presence useless. Tapered-type ORTLs appear to be much more intuitive to driver expectancy and appropriate for the three-dimensional characteristics …
