Technology Transfer Burkan Isgor (OSU) Several OSU researchers are leading the efforts to establish a formation factor of concrete as a rapid performance index. The OSU team is part of a pooled-fund study that involves several state DOTs and FHWA to establish standard protocols for the determination and specification of formation factor for durable concrete. Dr. Isgor's technology transfer activities are designed to overcome challenges surround inadequate training for practicing engineers with regard to the benefits and applications of these new developments. He is, through the following coordinated efforts: (1) developing and deploying of online calculators, (2) developing of online training modules, and (3) organizing educational webinars. David Hurwitz (OSU) Dr. Hurwitz has a state-of-the-art bicycle simulator in his laboratory, from which a significant portion of the research is driven. This work expands current calibration procedures to include latency, the time delay between an input stimulus and an observable system response. High latency can contribute to simulator sickness, as there is too much delay between a user's input and the system response compared to a real world system where physics provides extremely responsive feedback. This procedure will be designed to include a sensitivity analysis of a variety of input variables. The latency calibration findings will be combined with the previously prepared speed calibration framework in a technical guide that will be shared with bicycle simulator labs around the world. Jeff Ban (UW) Mobile sensing represents monitoring and data collection technologies that use sensors moving with the flow, as opposed to, from traditional fixed-location sensors, such as, loop detectors. The original research efforts investigated fundamental questions related to the wide deployment of mobile sensing in transportation, such as, how this may transform the way urban traffic modeling may change the way we study human mobility patterns on urban transportation networks. The success story efforts include: developing outreach materials, such as, video clips and presentations for detailed introductions of mobile sensing and the PI team's research work and accomplishments, and a redesign of the web pages related to mobile sensing research at the PI's Lab website. Chris Parrish (OSU) Unmanned aircraft systems (UAS) are proving increasingly valuable for a wide range of transportation applications. To fully leverage the successes of several recent PacTrans funded UAS projects and facilitate transition of the results to operational use within transportation agencies, Dr. Parrish hosted a UAS in Transportation Expo. Key topics included: 1) regulatory aspects of UAS in transportation, including FAA, state and local regulations; 2) safety planning; 3) UAS for structural inspections; 4) aircraft types (e.g., multirotor and fixed-wing) and characteristics (e.g., flight endurance, payload); 5) sensor selection (cameras, lidar systems, and direct georeferencing systems); and 6) IT infrastructure needs for operational UAS programs. A final report containing recommendations, best practices, and procedures was compiled from the Expo and shared with the participating DOTs and partners. Joe Louis (OSU) Dr. Louis has been applying the internet of things (IoT) paradigm of connected sensors to improve worker safety in work zones by delivering timely warnings of visibility and proximity related hazards. His system augments the use of location tracking with tracking of the worker's gaze to detect situations wherein the worker is unaware of their proximity to hazards. He has previously created a prototype for mounting on hardhats to detect potentially hazardous situation to implement the framework. This technology requires the setting up of anchors in the field, which presents a significant barrier to its widespread adoption on dynamically changing construction sites. Therefore, success story funds are being utilized to implement the developed framework in a commercially available "smart-helmet" produced by Daqri® that is engineered for use in rugged environments and is equipped with its own localization system. Yinhai Wang (UW) The Smart Road Node is a cost-effective, solar energy-driven, small, and lightweight communication node device, which can be used to formulate a V2X communication system for enhancing vehicle, bicyclist, and pedestrian safety. It can communicate with connected vehicles via LoRa and dedicated short range communications (DSRC), and with bicyclists, pedestrians, and unconnected vehicles through cell phones and other mobile devices via Bluetooth. This technology can be transferred to safety related public agencies or private companies. Outreach activities, like Smart Road Node demo workshops or webinars, are being carried out with success story funding. PACTRANS SUCCESS STORIES Once a sufficient pool of projects have been completed, PacTrans solicits submissions for "success stories." Success stories are just that, research that merits the added funding and effort to make sure that the findings and conclusions of the project are disseminated to the appropriate entities. Thus PIs submit proposals on how they would further disseminate and/or apply their findings in thoughtful and useful ways. The PacTrans board of directors and the advisory committee select a handful of projects to receive sufficient funding to execute the proposed activity(s). Here are brief summaries of the success stories that have been funded this year: 25 2017 – 2018 Annual Report
