Safety And Driver Behavior Studies At Multiple Lane Approaches To Stop-Controlled Intersections, Karen Schurr, Daniel Sitorius

Nebraska Department of Transportation: Research Reports

Multiple-lane approaches (MLAs) controlled by stop signs are becoming increasingly common in Nebraska. Installation of MLAs occurs when a single approach lane can no longer adequately serve the minor road traffic volume, and a signal is unwarranted because Manual of Uniform Traffic Control Devices (MUTCD) warrants are not satisfied (7, FHWA, 2003). A common example of a location at which MLA stop-controlled intersections can occur in Nebraska is the rural intersection of two state or federal highways. Forty such intersections in Nebraska were available for study in this research. Additionally, such intersections are often located in suburban areas of Nebraska …

Distracted Driving – Preliminary Analysis And Survey, Jerry G. Pigman, Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

This report primarily focuses on an attempt to document the level of driver distraction existing in Kentucky through an analysis of crash data and by conducting an observational survey of drivers. Additional research is cited as a means of comparing other studies with results from Kentucky, as well as establishing a definition of distracted driving. The status of laws related to use of cell phones in other states was summarized, and the recently passed legislation in Kentucky was noted by incorporation of the full text as an appendix.

It was determined from analysis of Kentucky data that if the three …

Analyzing Motorists’ Responses To Temporary Signage In Highway Work Zones, Yong Bai, Kris Finger, Yue Li

Civil and Environmental Engineering Faculty Research and Publications

For decades, the importance of highway work zone safety has increased considerably with the continual increase in the number of highway work zones present on highways for repairs and expansion. Rural work zones on two-lane highways are particularly hazardous and cause a significant safety concern due to the disruption of regular traffic flow. In this study, researchers determined motorists’ responses to warning signs in rural, two-lane highway work zones. The researchers divided vehicles into three classes (passenger car, truck, and semitrailer) and compared the mean change in speed of these classes based on three different sign setups: portable changeable message …

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. …

Kentucky Traffic Collision Facts 2010 Report, Kentucky Transportation Center, Kentucky State Police

Kentucky Transportation Center Research Report

KENTUCKY’S TRAFFIC COLLISION FACTS report for 2010 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 …
