Intersection Safety, Aemal Khattak
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). …

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 …

Nu-Deck Precast Deck Panels And Innovative Bridge Research And Construction, Maher K. Tadros, Charles J. Vranek
Nu-Deck Precast Deck Panels And Innovative Bridge Research And Construction, Maher K. Tadros, Charles J. Vranek
Nebraska Department of Transportation: Research Reports
Most of the deficiency in existing stringer-type bridges lie in deterioration of the bridge deck. Cast-in-place reinforced concrete decks experience cracking shortly after construction due to large differential creep and shrinkage with the supporting beams, and due to the temperature drop experienced during the hydration cycle. The NUDECK (Nebraska University) system is a full-depth precast/prestressed concrete bridge deck panel system. The combination of high performance precast concrete, where little creep and shrinkage occur after the deck is made composite with the beams, and two-way prestressing assure continued pre-compression of the deck during its life. With this system, construction time and …

Application Of Freeway Video Surveillance For Accident Investigation, Aemal Khattak, Yu Liu, Geza Pesti
Nebraska Department of Transportation: Research Reports
This report presents information on Research Project Number Z820 (UNL Ref. No. 26-1118- 0057-001) titled “Application of Freeway Video Surveillance for Accident Investigation.” Traffic accident investigation requires detailed documentation of the accident scene, vehicles, and persons involved in the collision. To adequately document an accident scene, investigating officers accurately record various measurements (e.g., skid marks, dimensions of different highway geometric elements, etc.). Typically, a measuring tape and/or a total station (theodolite) are used to obtain the needed measurements. Advances in digital imaging and computer technology make it possible to develop cost-effective traffic accident investigation system alternatives that provide sufficient accuracy, …

Winter Operations, Abrasives And Salt Brine, Geza Pesti, Yu Liu
Nebraska Department of Transportation: Research Reports
The primary objective of winter maintenance operations is to improve traffic safety and efficiency during winter storm periods. Abrasives and salt brines have been successfully applied to increase traction and prevent snow and ice from bonding to road surface. However, because of some undesired side effects, such as corrosion and damage to the environment, salt and abrasives may need to be supplemented by other substances in some areas. Powerful non-corrosive acetate-based chemicals have been considered by several agencies, but their high price has limited their use. Recent research has focused on the use of new, less corrosive, and highly effective …
