      <title>A Review of 3D Pavement Automatic Measurement System</title>
      <link>https://trid.trb.org/View/2000536</link>
      <description><![CDATA[In recent years, advances in sensor technology have made three-dimensional (3D) pavement automated measurement systems practical for collecting accurate road distresses. However, until now, there has been no information showing that there is an algorithm or software that can be adapted to collect data and achieve automatic recognition rates of more than 90%. The main impetus for this paper is derived from the lack of information on the mainstream methods that have been widely used in commercial applications, among them including laser triangulation, 3D laser scanner, and 3D PIXA based on stereo and fast line scan sensors. In view of the corresponding principle, this paper will focus on the hardware aspect, comparing their respective system specifications in regards to width range, depth range, detection speed, and accuracy. In addition, given the advantages and limitations, the recommended road type and detection range are proposed. Therefore, this paper will be able to serve as a reference for researchers, technical engineers, and managers for the selection of methods, system structures, and the future prospects.]]></description>

      <title>Methods for testing of driver assistance systems</title>
      <link>https://trid.trb.org/View/1814763</link>
      <description><![CDATA[For development and validation of driver assistance systems, appropriate test, measurement and evaluation methods are necessary to evaluate and optimize the system functions under realistic scenarios. However, currently, no appropriate test standards exist. TÜV SÜD Automotive, an innovative development partner for the automotive industry, has developed and applied methodologies to measure, test, analyze and evaluate these systems, based on established standards for driving dynamics. These methodologies are presented in the following excerpts. Sophisticated metrology equipment from GeneSys allows vehicles to be linked together in a “car to multi-car” solution. This approach enables the relative motion state of two vehicles to be dynamically measured and evaluated in all directions; x, y and z.]]></description>

      <title>Testing of In-Service Bridges Using Automated Ultrasonic Testing Methods</title>
      <link>https://trid.trb.org/View/1669378</link>
      <description><![CDATA[This goal of this project was to develop a prototype automated ultrasonic testing (AUT) system for detecting weld defects (flaws) in steel bridge members.  The study sought to investigate the effectiveness of AUT to improve the resolution, accuracy, and reliability of inspections. AUT systems are typically composed of an ultrasonic transducer coupled with an electronically-driven positioning vehicle for moving the transducer in a controlled and trackable manner. In this way the position and orientation of the transducer is controlled, such that scanning critical areas is ensured and test repeatability is increased. AUT systems may employ conventional ultrasonic transducers or phased array transducers. Phased Array Ultrasonic Testing (PAUT) methods can produce better defined and quantified defect indications as compared with conventional UT because of its beam-steering capabilities. This project researched and developed the mechanical and electrical equipment needed for an AUT system that could be applied for in-service bridge inspection. An industry scan of available scanning sensor architectures, data acquisition hardware, and analysis software was completed to inform the selection and design of the final inspection system. Based on this industry scan, a cost-effective prototype system based on a low-cost ($500) X-Y plotting printer system, with its inherent precision movement and programmable software, was developed.   Preliminary testing was completed using the AUT prototype on a steel plate to make initial refinements to the coupling apparatus used to ensure contact between the UT probe and test surface.  Laboratory specimens consisting of steel weld mock-ups with manufactured defects were also fabricated.  ASNT III inspectors performed baseline manual UT inspections with traditional ultrasonic technologies and evaluate results produced by the prototype system. Specific procedures were developed and field tests were conducted on the selected bridge to test and demonstrate the prototype system. The field demonstration of the AUT system was completed under the supervision of an ASNT III inspector who confirmed the quality of the data being generated by the AUT prototype system were consistent with the results of the qualified inspector.  Based on the comparative results and procedures between the AUT system and qualified inspectors, the AUT system showed promise for effective deployment in providing initial survey results of a weld integrity on a bridge in lab or fabrication shop settings, allowing more informed and time-efficient selection of where expert inspectors should perform more detailed scans. In addition, the AUT system was found to be well-suited for use with PAUT probes as the need for a consistent linear probe path for successful testing is met by the fixed rails used by the AUT system. Field testing of the prototype AUT system demonstrated the feasibility of deploying the AUT technology in the field to collect data. It was found that the quality of data collected by the AUT technology was consistent with quality of data that would be gathered by an ASNT Level III UT inspector.]]></description>

      <title>Model-based automatic test case generation for automotive embedded software testing</title>
      <link>https://trid.trb.org/View/1484736</link>
      <description><![CDATA[We propose a method to automatically generate software and hardware test cases from a UML model developed through a model-based development process. Where languages such as source-code languages are used within the model, input and expected values for each test case are generated using a custom parser. As a next step, unit test cases are combined to generate integration test cases using a bottom-up approach. Then these cases are converted into hardware test cases for approval testing of embedded systems, using XQuery and hardware mapping tables. We demonstrate this process by applying it to the power window switch module of a Hyundai Santa Fe vehicle. Our approach provides an automatic testing procedure for embedded systems developed by model-based methods, and generates test cases efficiently using a recombination of signals. In conclusion, our proposed method could help reduce the resources needed for test case generation from software to hardware.]]></description>

      <title>Advanced Technologies and Methodology for Automated Ultrasonic Testing Systems Quantification</title>
      <link>https://trid.trb.org/View/1475727</link>
      <description><![CDATA[For automated ultrasonic testing (AUT) detection and sizing accuracy, this program developed a methodology for quantification of AUT systems, advancing and quantifying AUT systems image-capture capabilities, quantifying the performance of multiple AUT systems, establishing a guidance document, conducting field tests, and delivering a guidance document for future inclusion in reliability-based design and assessment (RBDA) standards. Improvements for AUT of pipeline girth welds were identified by investigating: imaging techniques for AUT data, modeling and simulation tools for AUT technique development and validation, and quantification methodologies for measuring the performance of AUT systems. Throughout the course of the project, many AUT scans were conducted using both zonal and non-zonal inspection techniques. The quantification methodology provides guidance for quantifying the performance of AUT systems with respect to probability of detection (POD) and accuracy of flaw sizing. Field trials and lab trials demonstrated that a sector sweep of beam angles provides alternative imaging capabilities that may enhance current zonal techniques. Current methodologies used for quantifying detection and sizing limits for AUT systems vary and produce great variability in detection and sizing results. Consequently, a standardized quantification approach is recommended to reduce this variability. This investigation evaluated six AUT systems; flaw heights were detected between 2 and 4 mm with a 90% probability and a confidence level of 95% (a90/95). The use of ultrasonic modeling and inspection simulation software provided a good tool for developing and evaluating AUT procedures; and can be used to evaluate changes in essential variables.]]></description>

      <title>Hamburg Wheel-Track Test Equipment Requirements and Improvements to AASHTO T 324</title>
      <link>https://trid.trb.org/View/1403029</link>
      <description><![CDATA[In this study, a comprehensive experimental program was conducted to evaluate the capability of five commercially available Hamburg Wheel Tracking (HWT) equipment as well as their ability to accurately measure, control, and maintain the desired test conditions as specified in AASHTO T 324. Based on the results of this study, researchers were tasked to provide proposed revisions with commentary to AASHTO T 324 to enable the use of a performance type specification for Hamburg test equipment.  Modifications are proposed to address equipment capabilities, components, or design feature in order  to ensure proper testing and accurate, reproducible results.  Proposed modifications are discussed in this  report  to  ensure  repeatable  measurements  and that  the  results  from  different manufacturers  are  comparable.    These  modifications  include  change  to  temperature measurement and range, impression measurement system, data collection, and data analysis and  reporting.    In  addition  to  the  proposed  modifications  to  the  AASHTO  T  324 specifications, the vendors may need to modify their equipment to meet the new  specification requirements.]]></description>

      <title>Vision-Based Automated Crack Detection for Bridge Inspection</title>
      <link>https://trid.trb.org/View/1368507</link>
      <description><![CDATA[The visual inspection of bridges demands long inspection time and also makes it difficult to access all areas of the bridge. This paper presents a visual-based crack detection technique for the automatic inspection of bridges. The technique collects images from an aerial camera to identify the presence of damage to the structure. The images are captured without controlling angles or positioning of cameras so there is no need for calibration. This allows the extracting of images of damage sensitive areas from different angles to increase detection of damage and decrease false-positive errors. The images can detect cracks regardless of the size or the possibility of not being visible. The effectiveness  of this technique can be used to successfully detect cracks near bolts.]]></description>

      <title>Development of a Standardized Method for Making Characteristic Radar Measurements of Example Vehicles and Surrogate Targets</title>
      <link>https://trid.trb.org/View/1358483</link>
      <description><![CDATA[Testing of Advanced Driver Assistance Systems (ADAS) often requires the use of a surrogate vehicle to represent a real vehicle in conflict scenarios. Use of a surrogate vehicle is required if there is a potential for a collision during testing. In order to ensure that the test results are representative of what will occur on the road, the surrogate vehicle should appear to the test vehicle as a real car. This paper describes a method and equipment developed for measuring and analyzing the radar signature of typical vehicles and surrogate targets. The method was then applied to eight small passenger cars to better understand what the radar signature of representative passenger vehicles are. A special-purpose trolley was designed to serve as a portable, self-contained measurement, data acquisition and power platform. It consists of a wheeled trolley base and a vertical structure to which the various equipment are attached. The sensor trolley has 3 retractable feet that are used to make it a stationary device during measurements. The front two feet can be used for fine roll adjustment and the rear foot can be used for fine pitch adjustment. Mounted to the trolley are a commercial production 6-77 GHz RADAR sensor, a sensor bracket with roll angle level and scope sight, a data acquisition system, a laptop computer, a 12 volt battery and a power distribution box. Eight small passenger cars were measured, three sedans, three hatchbacks, and two microcars. Small passenger cars may represent a worst case in terms of vehicle visibility. The representative vehicle radar measurements were made taken from five viewing angles and at three distances for each angle. The data from these measurements are presented.]]></description>

      <title>A Novel Active Seafloor Pressure-Retained Multitube Sediment Corer</title>
      <link>https://trid.trb.org/View/1317663</link>
      <description><![CDATA[A novel minimally disturbed seafloor pressure-retained sediment corer driven by a self-served underwater fluid power system is presented. It features multiple independent two-stage cylinders with a piston rod to mount a core liner that can be penetrated into sediment and pulled back at a controllable speed. Each core tube is equipped with two ball valves to retain the in situ pressure of the seafloor sediment. The corer can be monitored in real time and controlled from the deck via a coaxial cable, such that operators onboard can choose the proper coring location, control the coring speed, and collect multitube pressure-retained cores in different sites during one deployment. The test prototype is equipped with only two tubes and deployed at a depth of 1,035 m in the South China Sea by the R/V Dayang No. 1 of China. Two tubes of sediment cores with in situ pressure retained have been successfully obtained.]]></description>
