Developing A Sustainable Freight Transportation Framework With The Consideration Of Improving Safety And Minimizing Carbon Emissions, Margaret Rita Neff, Yong Bai, Steven Schrock, Thomas E. Mulinazzi Jan 2010

Developing A Sustainable Freight Transportation Framework With The Consideration Of Improving Safety And Minimizing Carbon Emissions, Margaret Rita Neff, Yong Bai, Steven Schrock, Thomas E. Mulinazzi

Mid-America Transportation Center: Final Reports and Technical Briefs

Despite the difficulties of the American economy in recent years the transportation sector continues to expand. Freight transportation alone has been projected to increase enormously even if the economy as a whole only manages a very moderate growth. Not only does freight transportation use a large percentage of resources but it contributes significantly to America’s share of carbon emissions and affects the safety of the transportation system and all its users. These problems are only expected to increase as the volume of freight transportation is already reaching the limit of the American transportation infrastructure’s capacity and demand continues to increase. …


Centerline Curbing Treatment At Railroad Crossings For Improved Safety, Aemal Khattak, Dwight L. Mosby Jr., Gregory Mcknight, Brian Gardner Mar 2007

Centerline Curbing Treatment At Railroad Crossings For Improved Safety, Aemal Khattak, Dwight L. Mosby Jr., Gregory Mcknight, Brian Gardner

Nebraska Department of Transportation: Research Reports

The objectives of this research were to study unsafe actions of motor vehicle drivers at railroadhighway grade crossings, to evaluate centerline barriers in reducing those unsafe driver actions, and to note any maintenance or other issues with the barriers. Driver actions were observed at two railroad crossings before and after installation of centerline barriers. A comparison of observed driver actions in the pre- and post-barrier periods provided information on the effectiveness of the barriers in reducing unsafe driver actions while periodic inspection of the centerline barriers provided information on maintenance needs. A major concern of the Nebraska Department of Roads …


Intersection Safety, Aemal Khattak Mar 2006

Intersection Safety, Aemal Khattak

Nebraska Department of Transportation: Research Reports

The objectives of this project included a study to determine the safety effects of intersection type (unsignalized, signalized, and interchange) on Nebraska expressway intersections, quantification of the safety effects of a Collision Countermeasure System (CCS), and update of the Nebraska Department of Roads (NDOR) expressway intersection guidelines. The CCS is an Intelligent Transportation Systems (ITS) traffic control device to warn drivers of conflicting cross-traffic at rural, non-signalized intersections. The goal was that if found effective, the CCS will become part of the intersection designer’s options for expressway intersection design (other options being an interchange, traffic signals, and traffic control signs). …


Stochastic Algorithm For Improved Operations At Isolated High Speed Intersections, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta Jan 2006

Stochastic Algorithm For Improved Operations At Isolated High Speed Intersections, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta

Department of Civil and Environmental Engineering: Faculty Publications

The current practice of specifying simultaneous gap out logic at isolated high speed signalized intersections places constraints on the signal controller logic that cannot be satisfied under high congestion level. Further, it often results in degraded signal efficiency and dilemma zone protection. A stochastic approach is proposed in this paper with the objective of increasing safety and efficiency at these intersections.


Safety Evaluation Of Left Turn Lane Line Width At Intersections With Opposing Left Turn Lanes, Aemal Khattak, Bhaven Naik, Vijay Kannan Dec 2004

Safety Evaluation Of Left Turn Lane Line Width At Intersections With Opposing Left Turn Lanes, Aemal Khattak, Bhaven Naik, Vijay Kannan

Nebraska Department of Transportation: Research Reports

The objective of this research project was to evaluate the effectiveness of offset opposing left-turn lanes at signalized intersections in reducing the frequency and severity of left-turn related accidents. The Cities of Lincoln and Omaha offset opposing left-turns by widening leftturn lane lines in June 1999 at six intersections. The research team investigated traffic accident patterns between January 1994 and December 2002 at those six intersections by making comparisons with two control intersections (i.e. intersections at which left-turns were not offset by lane line widening) using a four-step research methodology. First, existing literature was reviewed to determine the extent and …

Zoonotic Diseases Of Carnivores And Occupational Safety Issues For Predator Control Employees, Michele T. Jay Jan 1996

Zoonotic Diseases Of Carnivores And Occupational Safety Issues For Predator Control Employees, Michele T. Jay

Proceedings of the Seventeenth Vertebrate Pest Conference 1996

The paper highlights some important zoonotic infections of carnivores in North America. The etiologic agents, routes of transmission, reservoirs, and methods for prevention are emphasized. Occupational safety issues for people working in predator control are discussed.


An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar Mar 1942

An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

During the past few years inquiries have been received regarding the cost of operation, efficiency, and performance of pressure gasoline and pressure kerosene stoves. Because of the method of operation and the use of gasoline as fuel, safety from fire and carbon monoxide has been frequently questioned. Not only is it necessary to have technical information about this type of appliance in order to compare it with other types but it is further important to know whether one type of burner is superior to another; whether one type of oven construction will give better results than another and in general …
