Improved Strategies For Deploying Vehicle-Actuated Control At Isolated Signalized Intersections, Michael J. Cassidy, Yu-Hao Chuang, Jeffrey Dunn Vitale

JTRP Technical Reports

This research has sought to demonstrate potential benefits from deploying enhanced vehicle actuation strategies at isolated signalized intersections. The work has exploited microscopic, stochastic simulation to evaluate impacts of enhanced vehicle-actuated (VA) control schemes for an array of operating conditions. Simulated outcomes (i.e. average vehicle delays) generated under the enhanced strategies were compared with outcomes resulting from more “conventional VA control policies. Findings from this work suggest that substantial delay reduction generally occurs by exploiting VA strategies which seek to 1) facilitate the use of the clearance interval by discharging vehicles, 2) shorten the duration of the required clearance interval …

New Treatment Combinations For Control Of Brush And Vegetation Management Along Indiana Roadsides, D. James Morré

JTRP Technical Reports

Also discovered and developed was a new, environmentally safe and effective TR series of additives that enhance the action of the auxin herbicides (trichlopyr, 2,4-D, picloram) for inclusion in both the brush control mixtures and control of milkweed, Canada thistle, bindweed, ground cherry and other perennial, herbicide-resistant …

A Decision Support System For Real-Time Snow And Ice Control, Hjalmar James Miedema, J. R. Wright

JTRP Technical Reports

Effective real-time snow and ice control operations require a timely initial call-out. A timely initial call-out is one that mobilizes the workforce slightly prior to the onset of hazardous road conditions. In order to estimate the onset of hazardous road conditions, the snow and ice control decision makers use available physical and meteorological information. New technologies are developed that could provide better information, thereby improving the ability to make timely initial call-outs. A systematic methodology for evaluating the benefit of additional information used in snow and ice control initiation is presented. The purposed methodology compares reduction in the direct and …

Predicting Traffic Impacts At Two-Lane Highway Work Zones, Michael J. Cassidy, Youngtae Son

JTRP Technical Reports

Maintenance or reconstruction activity on a two-lane highway often requires a lane closure. The implementation of “one-way traffic control,” required to maintain traffic flow throughout the work zone, typically produces significant motorist delay. This report describes the adaptation and application of queuing models, originally derived for intersections controlled by vehicle-actuated traffic signals, to estimate delay at two-lane highway work zones. The models estimate expected delay as a function of directional traffic demand rates, work zone physical length and observed traffic measures. Validation efforts using simulation suggest that the models accurately predict the impacts of two-lane highway lane closures.

Effects Of Salt And Trace Minerals For Bituminous Pavement Literature Review, Information Gathering, And Research Plan Development, Robert Allan Pittenger, Terry R. West

JTRP Technical Reports

A review of current literature on the effects of deicing salt and trace minerals, such as sulfate, on aggregate deterioration was conducted. Such deterioration in both Portland cement concrete, and bituminous pavements was reviewed. For Portland cement concrete, it was determined that current research on the effects of moisture and deicing salt on aggregates concrete matrix durability, with little discussion on the effects on aggregates. The effects of trace minerals in deicing salt are also rarely discussed. Pore size distribution, insoluble residue, absorption, and susceptibility to alkali-silica reaction all appear to affect aggregate durability in the presence of moisture of …

It primarily focuses on American Indian groups that used the NIMI region for various purposes in past historical times. The discussion of American Indian peoples emphasizes the three Federally-recognized tribes that reside in the NIMI region today, the Poncas, Santee Sioux, and Yankton sioux. Other groups that used the NIMI …

Solid Waste Disposal Site Characterization Using Non-Intrusive Electromagnetic Survey Techniques And Geostatistics, Gary N. Kuhn, Wayne E. Woldt, David D. Jones, Dennis D. Schulte

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Prior to the research reported in this paper, a site-specific hydrogeologic investigation was developed for a closed solid waste facility in Eastern Nebraska using phased subsurface characterizations. Based on the findings of this prior investigation, a surface based geoelectric survey using electromagnetic induction to measure subsurface conductivity was implemented to delineate the vertical and horizontal extent of buffed waste and subsurface contamination. This technique proved to be a key non-intrusive, cost-effective element in the refinement of the second phase of the hydrogeologic investigation.

Three-dimensional ordinary kriging was used to estimate conductivity values at unsampled locations. These estimates were utilized to …

Simplex Algorithm For Optimizing Drainage Design, Majid Ehteshami, Lyman S. Willardson, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A methodology and computer model is developed to determine economically optimum closed subsurface drainage systems in irrigated areas. The model maximizes net benefits, by comparing profit driven by crop yield to drain system cost and selects an optimum drain layout. The optimization methodology used, is the SIMPLEX method, Neider and Mead. The SIMPLEX model was linked to the subsurface drainage model DRAINMOD Skaggs [10], and to the surface hydraulic model KINE, Walker and Skogerboe[14]. The selected optimum drainage system maximizes the difference between total revenue, and the total cost of installation, operation and management of a particular drainage system. The …

Optimal Perennial Groundwater Yield Planning For Complex Nonlinear Aquifers: Methods And Examples, Shu Takahashi, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

Optimal perennial groundwater yield pumping strategies were computed for a complex multilayer aquifer with: (i) confined and unconfined flow, and (ii) many flows typically described by piecewise-linear (nonsmooth) equations. The latter flows account for over 50% of the aquifer discharge from the test area, the eastern shore of the Great Salt Lake in Utah. Normally utilized response matrix (RM) and embedding (EM) simulation/optimization modelling procedures did not converge to optimal solutions for this area; they diverged or oscillated. However, the newly presented linear RM and EM approaches satisfactorily addressed the nonlinearities posed by over 2000 piecewise-linear constraints for evapotranspiration, discharge …

Stepwise Pumping Approach To Improve Free Phase Light Hydrocarbon Recovery From Unconfined Aquifers, Grant Cooper, Richard C. Peralta, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

A stepwise, time-varying pumping approach is developed to improve free phase oil recovery of light non-aqueous phase liquids {LNAPL) from a homogeneous, unconfined aquifer. Stepwise pumping is used to contain the floating oil plume and obtain efficient free oil recovery. The pumping approach is developed using detailed simulations, multiple linear regression and graphical plots. The approach uses ARMOS©, an areal two-dimensional multiphase flow, finite-element simulation model. Systematic simulations of f~ oil area changes to pumping rates are analyzed. Pumping rates are determined that achieve LNAPL plume containment at different times (i.e. 90, 180 and 360 days) for a planning period …

Maximizing Conjunctive Use Of Surface And Ground Water Under Surface Water Quality Constraints, Muhammad Shafqat Ejaz, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A simulation/optimization (s/o) model is presented to address the increasingly common conflicts between water quantity and quality objectives. The model can assist water resources analysts in selecting compromise strategies for stream/aquifer systems in which the stream gains water from the aquifer. The water quantity objective is to maximize steady conjunctive use of groundwater and surface water resources. The water quality objective is to maximize waste loading from a sewage treatment plant {STP) to the stream without violating downstream water quality beyond acceptable limits. The STP discharge is proportional to human population. The two objectives conflict because an increase in groundwater …
