- Development of Hazardous Materials (HM) Shipper Prioritization Program: Technical BriefMarinik, Andrew; Schaudt, William A.; Daily, Brian; Bowman, Darrell Scott; Hanowski, Richard J. (Virginia Tech Transportation Institute, 2009-02)The Federal Motor Carrier Safety Administration (FMCSA) developed the Hazardous Materials Package Inspection Program (HMPIP) to focus on inspecting individual shipments at the roadside or on carriers’ docks. One output of this program is a resulting dataset that can be used to develop a performance-based prioritization of HM shippers for inspection. The Virginia Tech Transportation Institute (VTTI) was tasked to review, document, and recommend improvements to the HM Shipper Prioritization Program. As part of that effort, VTTI developed software titled the HM Shipper Prioritization Application (HMSPA) that was beta tested in a sample of states with existing shipper programs. The purpose of this report is to provide documentation on the development process and the final HMSPA design that was completed by VTTI.
- Draft Final Report: Development of Hazardous Materials (HM) Shipper Prioritization ProgramSchaudt, William A.; Bowman, Darrell Scott; Marinik, Andrew; Baker, Stephanie Ann; Trimble, Tammy E.; Hanowski, Richard J. (Virginia Tech Transportation Institute, 2009-02-28)In the mid-1990s, an attempt was made to develop a performance-based prioritization for Hazardous Materials (HM) shippers. During this attempt it became apparent that there was insufficient performance data to develop such a system. In response, FMCSA developed the HM Package Inspection Program (HMPIP) to focus on inspecting individual shipments of HM at the roadside or on carriers’ docks. Due to the improvements made over the years to the package inspection data collected during HMPIP inspections, HM incident data, and improved departmental data identifying companies involved in shipping HM, FMCSA has begun a second effort to develop a performance-based prioritization of HM shippers. The purpose of the current project was for the Virginia Tech Transportation Institute (VTTI) to review, document, and recommend improvements to FMCSA’s HM Shipper Prioritization Program. This project consisted of six major tasks, all of which were successfully executed by VTTI. After the kick-off meeting and the successful completion of a detailed work plan, a peer review committee was formed. Members of the peer review committee were to participate in two peer review meetings during the course of the project. The purpose of the first peer review meeting was to have the study methodology and data collection techniques reviewed by the committee. The purpose of the second peer review meeting was to review the study findings and conclusions. Another major step in this project was to review and examine the current Hazardous Materials (HM) Shipper Prioritization Program, which included two distinct prioritization algorithms, and to develop software titled the HM Shipper Prioritization Application (HMSPA). HMSPA was then beta tested in states with existing shipper programs. The focus of these onsite tests was usability testing with potential end users. Both subjective and objective data were collected by way of questionnaires and performance tasks. All results were very positive indicating that the beta version, with minor modifications based on user recommendations, should move forward into a fully functioning application for FMCSA.
- Enhanced Rear Signaling (ERS) for Heavy Trucks: Phase III – Development of Field Operational TestSchaudt, William A.; Bowman, Darrell Scott; Trimble, Tammy E.; Medina, Alejandra; Bocanegra, Joseph L.; Baker, Stephanie Ann; Marinik, Andrew; Wierwille, Walter W.; Hanowski, Richard J. (Virginia Tech Transportation Institute, 2010-09)The Enhanced Rear Signaling (ERS) for Heavy Trucks project was directed at investigating methods to reduce or mitigate those crashes where a heavy truck has been struck in the rear by another vehicle. Prior to the current effort, two phases of work had been completed on this project. The purpose of the current effort, Phase III, focused on exploring the benefits of the countermeasures developed in previous phases, and to develop a plan for a large scale Field Operational Test (FOT). During crash database analyses in the current project it was found that, in 2006, there were approximately 23,500 rear-end crashes involving heavy trucks which resulted in 135 fatalities and 1603 incapacitating injuries. Many different types of ERSs were investigated in this study across both the auditory and visual modalities. Visual warning signals were found to be the most beneficial at signaling following-vehicle drivers (more specifically rear warning-light configurations). The research team recommended that one specific configuration be selected for real-world data collection based on its high performance and the potential success of future design implementation. Overall, the final radar-based cautionary ERS system was robust in real-world driving conditions and is recommended for an FOT.
- Guidelines for the Operation, Assembly, Repair, Testing and Inspection of Hazardous Material Cargo TanksBowman, Darrell Scott; Marinik, Andrew; Trimble, Tammy E.; Baker, Stephanie Ann; Selz, Allen (Virginia Tech Transportation Institute, 2009-06-30)This document consists of guidelines and recommendations related to operations, assembly, repair, testing and inspection of cargo tanks hauling hazardous materials. This document is the result of research findings from the project titled: Research to Identify the Factors that Affect the Service Life of Cargo Tanks [VTRC # 08-0669-10, FMCSA # TMC75-07-H-00008 Task Order # 2].
- Human Factors Evaluation of Level 2 and Level 3 Automated Driving Concepts: Concepts of OperationMarinik, Andrew; Bishop, Richard; Fitchett, Vikki L.; Morgan, Justin F.; Trimble, Tammy E.; Blanco, Myra (United States. National Highway Traffic Safety Administration, 2014-07)The Concepts of Operation document evaluates the functional framework of operations for Level 2 and Level 3 automated vehicle systems. This is done by defining the varying levels of automation, the operator vehicle interactions, and system components; and further, by assessing the automation relevant parameters from a scenario-based analysis stand-point. Specific to the “Human Factors Evaluation of Level 2 and Level 3 Automated Driving Concepts" research effort, scenarios and literature are used to identify the range of near- to mid-term production-intent systems such that follow-on research topics with highest impact potential can be identified through commonalities in operational concepts.
- Vehicle-width Measurement Technology Development: Phase I Technical MemorandumMarinik, Andrew; Trimble, Tammy E.; Baker, Stephanie Ann; Bryson, Jared; Schaudt, William A.; Bowman, Darrell Scott (Virginia Center for Transportation Innovation and Research, 2011-08)The Virginia Tech Transportation Institute (VTTI) was tasked with investigating the feasibility of developing a vehicle-width measurement and alert system to reduce over-width violations in Virginia Department of Transportation’s (VDOT) work zones. A two-phase approach was developed to investigate the measurement system feasibility. During Phase I, the focus of the current report, VTTI first generated design criteria with support from stakeholders (i.e., the Virginia Center for Transportation Innovation and Research [VCTIR] and VDOT). Next, researchers and engineers assessed existing vehicle-width measurement systems against these criteria to determine design gaps, and then explored solutions (e.g., new technologies) to these design gaps. Identified potential solutions were then tested on the Virginia Smart Road. In the end, VTTI developed a preliminary system architecture for a vehicle-width measurement system. Based on the findings of this research effort three recommendations are offered to guide future development of a vehicle-width measurement system.
