Traffic Signals In School Zones, Kevin S. Lee, Darcy M. Bullock
Darcy M Bullock
Traffic signals are used to control the right of way at intersections. Strict engineering guidelines are published in the Manual on Uniform Traffic Control Devices (MUTCD) that engineers use to determine if a traffic signal is “warranted”. The warrants provide consistent national balance between mobility, safety, efficiency, and costs. However, signalized intersections are often viewed by the general public as safer then unsignalized intersections. This belief is often heightened when there are personal injuries and even higher when children are involved. Parents, city officials, and local interest groups often vigorously request the installation of a traffic signal. After these requests …
Stochastic Algorithm For Improved Operations At Isolated High Speed Intersections, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta
Stochastic Algorithm For Improved Operations At Isolated High Speed Intersections, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta
Darcy M Bullock
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.

Assessing The Structural, Driver And Economic Impacts Of Traffic Pole Mounted Wind Power Generator And Solar Panel Hybrid System, Anuj Sharma Ph.D., Justice Appiah Ph.D., Scott K. Rosenbaugh
Assessing The Structural, Driver And Economic Impacts Of Traffic Pole Mounted Wind Power Generator And Solar Panel Hybrid System, Anuj Sharma Ph.D., Justice Appiah Ph.D., Scott K. Rosenbaugh
Mid-America Transportation Center: Final Reports and Technical Briefs
This project evaluates the physical and economic feasibility of using existing traffic infrastructure to mount wind power generators. Some possible places to mount a light weight wind generator and solar panel hybrid system are: i) Traffic signal pole and ii) Street Light pole. Traffic signal poles can themselves have multiple designs depending on type of mount (mast arm vs. span wire) and the width of the intersection (load carried) etc. The close proximity of street light poles and traffic signal poles to the traffic cabinets, which can be used for storing the battery banks, make them good candidates to mount …
Truck Safety At Highway-Rail Grade Crossings, Aemal Khattak, Miao Gao
Truck Safety At Highway-Rail Grade Crossings, Aemal Khattak, Miao Gao
Mid-America Transportation Center: Final Reports and Technical Briefs
Safety at highway-rail grade crossings (HRGC) is a major concern for different agencies because increasing highway and rail traffic presents a greater risk of crashes at these locations. In 2008, there were 2,391 crashes and 523 fatalities reported at grade crossings across the U.S. Of these, 187 crashes were reported in Nebraska, including 35 involving trucks with trailers and 10 involving trucks only. At gated crossings, gate-related violations by truck drivers are a primary cause of collisions between trains and trucks. The objectives of this research were to report on the frequency and type of gate violations by truck drivers …
Evaluation Of A Prototype Desktop Virtual Reality Model Developed To Enhance Electrical Safety And Design In The Built Environment, Martin Barrett, Jonathan Blackledge
Evaluation Of A Prototype Desktop Virtual Reality Model Developed To Enhance Electrical Safety And Design In The Built Environment, Martin Barrett, Jonathan Blackledge
Articles
The use of Desktop Virtual Reality (VR) systems for enhancing electrical safety and engineering design is a novel prospect for both practicing and student electrical services engineers. This innovative approach, which can be readily accessed via the World Wide Web, constitutes a marked shift in conventional learning and design techniques to a more immersive, interactive and intuitive working and learning environment. This paper initially identifies the unique characteristics of desktop web based VR technologies and highlights the educational affordances offered by working in such an environment. Subsequently, using a prototype model titled ‘Virtual Electrical Services’, a case study is carried …
Head Ejection During Barrier Impacts, Scott K. Rosenbaugh, Ronald K. Faller, Dean L. Sicking
Head Ejection During Barrier Impacts, Scott K. Rosenbaugh, Ronald K. Faller, Dean L. Sicking
Department of Civil and Environmental Engineering: Faculty Publications
During oblique vehicular impacts with longitudinal barriers, an occupant’s head is often ejected out of a side window. When this occurs, the occupant’s head can contact the barrier or an object attached thereto. This impact event, often termed head slap, normally produces a serious injury or fatality. Roadside barriers and any attached hardware should be designed with sufficient offset at the top to preclude head slap for most impact conditions. The goal of this study was to identify the extent of head ejection that can be expected during high-speed crashes with longitudinal barriers. High-speed videos of full-scale vehicle crash tests …

Kentucky Transportation Center Research Report
KENTUCKY’S TRAFFIC COLLISION FACTS report for 2012 is based on collision reports submitted to the Kentucky State Police Records Branch. As required by Kentucky Revised Statutes 189.635, “every law enforcement agency whose officers investigate a vehicle accident of which a report must be made...shall file a report of the accident...within ten days after investigation of the accident upon forms supplied by the bureau.” The stated purpose of this requirement is to utilize data on traffic collisions for such purposes as will improve the traffic safety program in the Commonwealth. Data contained in this report are based solely on the observations …
