    PacTrans Hosts Region 10 Transportation Safety Workshop

    The PacTrans Region 10 Transportation Safety Workshop on May 5 drew representatives from universities, public agencies, and private companies across the Pacific Northwest to discuss important regional transportation safety issues. This workshop was jointly organized by PacTrans, ITE Washington, ITE Oregon, ITE Idaho, and ITE Alaska. Open only to invited participants, more than 70 attendees, both in-person and online, joined the workshop at the Talaris Conference Center to identify critical regional transportation safety issues for PacTrans to study. Regional transportation experts representing industry, agency, and university perspectives contributed to PacTrans’ research agenda, shared ongoing efforts in addressing critical safety problems, and solidified partnerships in transportation safety research and practice.

    The morning sessions included keynote talks on transportation safety priorities at federal and state levels from Kenneth Feldman, Federal Transit Administration (FTA), and Chris Madill, Washington Traffic Safety Commission (WTSC), respectively. From a national standpoint, Feldman explained the FTA’s vision to make safe transportation safer and to see safety management systems (SMS) embedded in every transit agency. As executive director of WTSC, Madill outlined Target Zero, which aims for zero deaths and serious injuries on roadways by 2030, and highlighted key issues including motorcycles and pedestrians.

    The transportation agency panel, moderated by Dongho Chang, City of Seattle, was comprised of representatives from Washington State Department of Transportation, Idaho Transportation Department, City of Portland, and Alaska Department of Transportation. Common threads throughout the panel included prioritization of decreasing vehicle run off the road crashes, communicating effective safety messages with the public, and the importance of enforcement.

    Carlos Ortiz, ITE Western District President, moderated the ITE panel with representatives from the City of Seattle, Toole Design Group, and Leidos. While covering a range of topics, conversational themes emerged on more and better data for vulnerable users, such as bicyclists and pedestrians, and regulatory and societal trends with safety implications.

    To address specific research and education needs, the final session placed participants into several working groups to concentrate separately on safe infrastructure, safe users, and safe operations. The safe operations group identified pedestrian risk locations and behaviors as a top priority, as well as acquiring data on speed, research on bicycle improvements, and collision data. Among the priorities outlined by the safe infrastructure group, effectiveness of measures to reduce collisions, a template for collection and analysis of collisions, implications of measures on all users, and high-tech solutions for managing risk to lifelines ranked in the top four. Finally, the safe users group cited defining the tipping point of bicycle usage, data acquisition, changing user demographics in transportation, and the notion of designing transportation facilities to elicit safer operating speeds as vital issues for research in the region.

    With this information and support, PacTrans is equipped to continue investing in high-impact transportation safety research for the Pacific Northwest.

    Imad Al-Qadi Speaks on Uses of Ground Penetrating Radar

    Dr. Imad Al-Qadi, an internationally renowned professor in pavement materials and engineering, visited the University of Washington on April 28 to speak at the Spring PacTrans Regional Transportation Seminar. Dr. Al-Qadi, Founder Professor at the University of Illinois at Urbana-Champaign, delivered his talk entitled “Transportation Infrastructure Assessment Techniques Using Ground Penetrating Radar.” (Watch the recorded lecture).

    Continuous monitoring of transportation infrastructure allows for the maintenance of durable and safe systems. Ground penetrating radar (GPR) technology, based on electromagnetic waves, is an important non-destructive evaluation method, and yet GPR works better in some situations than in others. Bridge and pavement assessment, primarily for estimating layer thickness and localizing moisture accumulation within structure layers, has successfully used GPR.

    PacTrans, Imad Al-Qadi

    However, the “images” obtained from GPR-reflected signals are dependent on the priori unknown dielectric properties of structural materials, which can make GPR data interpretation difficult. It can also prove difficult to detect layer interfaces, but signal and data processing techniques have been developed to estimate the dielectric properties of surveyed structures from GPR reflected signals. These techniques have improved GPR data interpretation and the quality of the GPR signal.

    GPR provides quick and reliable information about subsurface characteristics when appropriately used. Pavement layer thickness can be accurately predicted, for example, as well as the location of rebar.

    Dr. Al-Qadi has been working on GPR research for more than two decades, among his other diverse research interests. He is the Director of the Advanced Transportation Research and Engineering Laboratory (ATREL) and the founding Director of the Illinois Center for Transportation (ICT). A registered professional engineer, Dr. Al-Qadi has authored/co-authored more than 550 publications and has delivered more than 550 presentations, including numerous keynote lectures.

    Presentation Title

    Transportation Infrastructure Assessment Techniques Using Ground Penetrating Radar

    Abstract

    The continuous monitoring of transportation infrastructure is necessary to maintain a durable and safe system. Many noninvasive techniques have been used including instrumentation, acoustic emission, infrared, and electromagnetic waves.  Ground penetrating radar (GPR) technology based on electromagnetic waves has been used to assess the performance of transportation facilities for the past three decades. After all this time, the main question remains: “How well does GPR work and under what conditions?” Results show that while GPR works well for some situations, it is not appropriate for others. GPR has been successfully used for bridge and pavement assessment, primarily for estimating layer thickness and localizing moisture accumulation within structure layers. However, GPR data interpretation is often difficult because the “images” obtained from GPR-reflected signals are dependent on the priori unknown dielectric properties of structural materials. In addition, GPR cannot detect layer interfaces unless a significant contrast in the dielectric constants exists between the two considered materials. GPR data analysis can also be cumbersome and unreliable due to the large amount of data collected during the surveys. Various signal and data processing techniques have been developed to estimate the dielectric properties of surveyed structures from GPR reflected signals. These processing techniques have been successfully used to enhance the accuracy of GPR data interpretation results and to improve the quality of the GPR signal. Among his diverse research interests, Dr. Al-Qadi has been working on GPR research for more than two decades. He is currently working on utilizing GPR data to predict in-situ real-time asphaltic material density. Dr. Al-Qadi will discuss the recently developed techniques and their field application for quality control/quality assurance, predicting the layer thicknesses of pavement systems, detecting flaws, and predicting density of asphalt concrete.

    PacTrans Student Leadership Training: Marsha Anderson Bomar and the Language of Leadership

    Marsha Anderson Bomar is a transportation entrepreneur, leader, and trailblazer for women in transportation engineering with a list of awards and recognitions that rivals the length of a term paper. To get to where she is today, Anderson Bomar recognizes the importance of developing strong communication skills for career and leadership success. For the PacTrans Student Leadership Training on April 20, Anderson Bomar critically examined the way language can work for and against us, the communication differences between men and women, and what students can do now to build skills to grow as strong leaders.

    Of particular focus were the challenges faced by women in light of different communication styles. For instance, Anderson Bomar explained that women “often start off with words that weaken what we say, even if we’re sure.” I think, I believe, I guess all become disclaimers in the way women introduce ideas.

    “If the idea is even worthy of being spoken, don’t undermine it,” said Anderson Bomar. She offered a more confident way of posing an idea: “I have an idea I would like to run by you. It may need some refining, but it’s good.”

    In addition to gender, generational differences offer an opportunity to bridge the language style divide. Anderson Bomar cited sports as a galvanizing force of the baby boomer generation. By using sports-oriented terms such as “game plan,” one can appeal to and incite action in this age group, particularly with men.

    Anderson Bomar also offered suggestions for how students can prepare for leadership now, including practicing public speaking. Also, when the opportunity for volunteering to participate on a project arises, say yes. Eventually, volunteer to lead a project and in the process, Anderson Bomar explained, students will simultaneously learn and build confidence.
