If you have been to Boston Logan International Airport (BOS) recently, you know that changes are everywhere. The TRB Airport Cooperative Research Program’s Impacts on Practice: Improving the Airport Experience amid Changing Guest Expectations highlights how ACRP Report 157: Improving the Airport Customer Experience a... http://www.trb.org/Main/Blurbs/183340.aspx e3a2ab53-dd7a-f111-b8bf-20040feec779 Wed, 08 Jul 2026 04:57:24 GMT Regular inspection of wooden railroad bridges is critical to public safety and infrastructure reliability. Traditional inspection methods often require workers to access hard-to-reach areas, making inspections dangerous, time-consuming, and costly. Many bridges are located in remote areas, making them especially difficult to inspect thoroughly using manual techniques.  TRB’s Rail Safety IDEA Final Report for Project RS-57 , Multi-Sensor Drone-Based Imaging Synthetic Aperture Radar System for Railway... http://www.trb.org/Main/Blurbs/183339.aspx 4a26d8cf-d87a-f111-b8bf-20040feec779 Wed, 08 Jul 2026 04:25:05 GMT Rail defects, such as transverse defects and rail foot fatigue cracking, remain a major safety concern for the railway industry. Conventional nondestructive evaluation (NDE) methods often face limitations in sensitivity, accessibility, inspection speed, and dependence on operator experience. These limitations underscore the need for a new inspection paradigm capable of delivering reliable, repeatable, and scalable rail NDE.

Traditional on-the-job (OTJ) and instructor-led training models, while essential, are becoming increasingly difficult to scale because the experts who deliver them are leaving the workforce. In addition, classroom training alone cannot capture the tacit, context-dependent judgment that experienced inspectors rely on every day.

Travelers now spend more time in airport terminals, often carrying additional personal items and expecting higher levels of comfort, convenience, and service. As airports have adopted social media and other real-time feedback tools, terminal restrooms—often the first and last places passengers visit in an airport—have emerged as one of the most consistent factors impacting the passenger experience. The TRB Airp... http://www.trb.org/Main/Blurbs/183335.aspx fb62022a-7bba-f011-b8b7-20040feec779 Wed, 05 Nov 2025 14:19:00 GMT When communities are faced with hurricanes, wildfires, and other natural disasters, airports serve critical response and recovery roles by enabling evacuations and the flow of emergency resources, supplies, and personnel. Yet when these same disasters damage airports and disrupt airport operations, response and recovery times in affected communities can be significantly delayed.  This ACRP Impact on Practice highlights how ACRP Report 73: Airport-to-Airport Mutual Aid Programs —and the tools, strat... http://www.trb.org/Main/Blurbs/183334.aspx b3ba9b08-70ba-f011-b8b7-20040feec779 Wed, 05 Nov 2025 08:01:00 GMT The size and mass of the private vehicle fleet in the United States have increased over time due to many factors, including prioritization of vehicle occupant safety, vehicle standards, and consumer preference. Studies have consistently found that pedestrians are likely to sustain greater injury from an SUV than a car, particularly at higher speeds. While larger, heavier vehicles increase injury risk for people walking, bicycling, and rolling in the event of a crash, there are still unanswered questions... http://www.trb.org/Main/Blurbs/183336.aspx 75cdc85e-81ba-f011-b8b7-20040feec779 Wed, 05 Nov 2025 05:04:10 GMT As the asphalt pavement industry advances toward the use of higher reclaimed asphalt pavement (RAP) contents in asphalt mixtures, it becomes increasingly important to accurately assess the quality and variability of RAP to ensure consistent pavement performance. Final Report for NCHRP IDEA Project 245: Simple and Rapid Tests for Assessing Quality and Consistency of Reclaimed Asphalt Pavement (RAP) for Recycled Asphalt Mixture Applications documents a project that investigated innovative methods for dete... http://www.trb.org/Main/Blurbs/183333.aspx b7b86096-59b6-f011-b8b7-20040feec779 Fri, 31 Oct 2025 04:04:10 GMT Cantilevered traffic signal structures are critical components of urban infrastructure. However, their slender, cantilevered design makes them particularly vulnerable to wind-induced vibrations, which can lead to fatigue failures at the pole-to-mast arm connections—locations where stress concentrations are highest. Despite ongoing research into fatigue-rated joints and passive damping devices, limited attention has been given to the real-world aerodynamic behavior of these structures under natural wind ... http://www.trb.org/Main/Blurbs/183332.aspx d5d85f89-d5a9-f011-b8b5-20040feec779 Wed, 15 Oct 2025 14:04:10 GMT Highway construction workers are regularly exposed to loud and complex noise environments from equipment, tools, and nearby traffic. While hearing protection equipment (HPE) is essential for preventing hearing loss, it often blocks important warning sounds—such as backup alarms or vehicle intrusion alerts—that are vital for worker safety.
