Abstract:The Advanced Pavement Evaluation (APE) prototype system combines multiple sensors to detect, measure, and assess the condition of sub-surface features, including in-pavement traffic sensors, pavement structures, and defects or deterioration of such structures. In phase II, the research and… more
Abstract:To properly simulate nighttime visibility conditions for driving simulation, one must first consider visibility issues in human vision. From a safety point of view, the driver must see road markings to maintain lane position and navigate complex intersections. The driver must also be able to… more
Abstract:TRI proposes to develop reliable methodology and protocols for in-service inspection,recertifying and retiring DOT COPVs to maximize service life while ensuring personnel safety. This method must be sufficiently robust to prevent in-service failures, while being straightforward and affordable enough… more
Abstract:Various methods for increasing seat belt usage have been investigated over the last several years including visual and audible warnings currently installed in today’s vehicles. In spite of these attempts, FMCSA research has shown that drivers of about 59% of commercial motor vehicles (those… more
Abstract:Current inspection, maintenance and lifetime estimation practices for composite cylinders have been adopted from earlier NASA research. WavesinSolids LLC are proposing a technological based on an acoustic emission (AE) technique for the in-service testing of composite cylinders. The approach will… more
Abstract:As stated in the solicitation, the pavement infrastructure in the US covers a large surface area and requires intensive energy and natural resources. In addition, the surface of the pavement is typically impermeable, causing negative consequences. Vehicles that travel over these pavements are also… more
Abstract:We propose a Smartphone based system that can integrate information commonly available on a mobile phone and real time traffic signal phasing data to provide assistance to pedestrians and cyclists for safer intersection crossing. GPS accelerometer and digital compass information from a smart phone… more
Abstract:A nondestructive tool will be developed to quatitatively assess residual stress in pipelines from the exterior and through coatings. Residual stress is a critical factor that determines the cracking susceptibility of pipeline steels, but existing methods for measuring mechanical damage in pipeline… more
Abstract:Mechanical damage (typically from third party excavations) is the most frequent cause of leaks and ruptures in pipelines. Surface corrosion is also a threat to pipeline integrity. Currently used techniques for assessing damage by means of in-line inspectin and in-ditch tools are not accurate… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
