Additional passenger fatalities and injuries can occur in rollover-type derailment accidents due to failures of glazing retention mechanisms on passenger railcars. In recent accidents, a key failure mode is shearing off the external rubber gasket that secures the glazing panes as the side of the railcar drags along the ground. Once the gasket fails, the glazing pane is pushed inside, leaving an op ...

NDT Corp. will take the currently developed ACTT system, which can accurately assess the internal condition of concrete crossties and increase its speed.FRA 23-FR1 requests a system that at high speeds can assess both the internal and external condition of concrete crossties.Currently there are systems that can perform the external assessment at the required speeds.However, there is no system that ...

First responders to hazardous material (HAZMAT) incidents face many safety risks daily, such as exposure to hazardous chemicals and toxic gases, which can be difficult to detect. Although there have been advancements in wearable sensors for hazardous gases, sensor technology for HAZMAT incident response lags behind sensor technology advancement in biomedical fields. There is a need to integrate se ...

This research proposes a data-driven and multi-perspective solution to reduce injuries and fatalities due to bus collisions with other vehicles. It goes beyond reviewing historical bus crash reports by collecting field LiDAR data for better understanding a variety of factors that may contribute to bus collisions and injuries/fatalities. It also recognizes that collision avoidance technologies (whi ...

According to a survey completed by NCAT in 2019, as part of the NCHRP 20‐07 project, 36 DOTs (out of 43 responded) consider fatigue cracking as the most common failure mode that the agency wants to address. However, in the same survey, 34 of the DOTs also indicated that fatigue cracking test is not required in their mix design specifications. This is primarily because a simple, practical, and ro ...

While purchase of e-buses has accelerated in recent years, its adoption is still in its infancy, and transit agencies face technological, financial and institutional challenges. Amongst the range of technical challenges, charging infrastructure and power limitations create major barriers for evaluation of the appropriate model and type of e-bus. A significant challenge is the relatively low energy ...

In-place resurfacing of asphalt-based wear layers is an increasingly common method of roadway rehabilitation. With the addition of waste microplastics to bitumen binders as performance improvers, the grinding of asphalt during in-place resurfacing potentially brings microplastic particulate pollution to every community in the US. In addition, the wear of roadway surfaces is a known major source of ...

This project intends to develop a sensor system that allows in-situ measurement of concrete’s pore solution resistivity, to supplement existing procedures for durability assessment. The innovation includes one or more sensors that are embedded inside concrete and a mobile measuring device to interrogate the sensor.Phase I project will explore candidate body materials for the sensor, manufacturin ...
