These surveys are used by the airport to analyze when action is needed to avoid or remediate impingements on airspace (e.g., reduce the height of trees near runways); by airlines to analyze flight paths for their aircraft; and by the Federal Aviation Administration (FAA) to analyze and design new instrument approaches, including global positioning system (GPS) approaches. Airports also use these surveys to update airport layout plan (ALP) drawings that may become the basis for restricting the heights of structures that could impinge on airspace and to note locations of temporary potential obstructions (e.g., construction cranes). The National Oceanic and Atmospheric Administration’s (NOAA) National Geodetic Survey (NGS), operating under a series of interagency agreements with the FAA, is responsible for certifying that information developed from obstructions surveys meet the requirements for operation of the National Airspace System. Obstructions data collected and information derived from those data for ALP development may go beyond NGS-administered requirements. Most obstructions-survey data are obtained using field-survey and photogrammetric methods. A traditional NOAA-certified obstruction survey takes approximately 6 months, and a backlog of demand for such surveys far exceeds the funding available under federal programs, so that some airports must operate with obsolete and possibly inaccurate obstructions information. In addition, introduction of new GPS approaches at airports has increased demand for obstructions-survey data and lack of resources for obstructions surveys impedes FAA’s ability to support this new technology. Seeking to reduce costs and enhance accuracy of obstructions surveys, the FAA and NOAA have been conducting research on the use of airborne LIDAR technology. This research has proven that airborne LIDAR data can be used effectively in analysis and mapping of obstructions, including treetops and poles, accurately. Now that use of airborne LIDAR data has been proven technically effective for obstruction analysis, further research is needed to establish a cost-effective methodology that airports and their consultants can adopt to procure, process, and use these new data. The objectives of this research are (a) to describe requirements that must be met to use LIDAR data in aeronautical obstructions surveys and airport layout plan (ALP) elevation surveys; (b) to recommend procurement specifications and procedures that could be used by airports or other agencies for procuring and using LIDAR data; and (c) to describe the technical bases that could justify acceptance of LIDAR-based obstructions surveys by the NGS, FAA, airports, and airlines./p FAA , USD350,000.00 , Completed Increased Understanding of Driver Visibility Requirements This research project will develop a hybrid human/computer model of the quantity and quality of visual information needed to navigate certain curves in the roadway safely and effectively at night. FHWA , USD1,309,272.00 , Completed Ramp Incident Data from Selected Large and Medium Hub Airports FAA , Completed Flexural Fatigue Performance of an Ultra-High Performance Concrete Recent advances in concrete materials have led to a new generation of cementitious materials, namely ultra-high performance concrete (UHPC). This concrete possesses advanced properties in terms of compressive behavior, durability, and tensile load carrying capacity. UHPC attains these behaviors via an optimized gradation of cementitious materials, chemical admixtures, and steel fiber reinforcement. The current project aims to investigate the tensile fatigue behavior of this type of concrete through the flexural testing of 18 medium scale prestressed rectangular beams. In this test program, the cyclic load levels will focus on the cracking strength of the UHPC so as to allow for the determination of the steel fiber reinforcement behaviors under fatigue loading. FHWA , Completed Foundation Health Monitoring Systems A series of field investigations are underway to demonstrate foundation monitoring systems and utilize data for enhanced engineering assessment of structural performance. The new I-35W bridge in Minneapolis and the Woodrow Wilson Bridge in Virginia are current test sites. FHWA , Completed NDGPS Reference Station Modernization This project involves research to define existing global positioning system capability area. FHWA , Completed Evaluation of Preventive Maintenance Treatments Preventive maintenance is the planned treatment of pavements that provides protection, decreases the rate of deterioration and adds 5 to 10 years to the service life of the pavement. Agencies must determine which of the many treatments that are available provides the most benefit for the various stages of a pavements life. In this study an evaluation will be performed of two seal treatments to provide cost/benefit data and assist in the updating of Mississippi DOT?s ?decision trees? that are utilized to determine which preventive maintenance treatment provides the most benefit for each pavement condition. FHWA , USD90,000.00 , Completed Countermeasures to Reduce Big-Rig Crashes The Arizona Department of Transportation’s (ADOT?s) Motor Vehicle Division reported that trucks (large and small) constitute 27% of vehicles involved in crashes and 30% of fatal crashes. Although big-rig crashes are less frequent than those involving passenger cars, their impact on fatality and traffic congestion are far greater than passenger car related crashes. Hence, countermeasures to reduce big-rig crashes are crucial from the safety and congestion management standpoint. The objectives of this research are to identify freeway segments in Arizona with high frequencies of big-rig crashes and to develop countermeasures to reduce the probability of incident occurrence.
