A nondestructive evaluation method is proposed for imaging in-roadway sensors, anticipated to allow them to be located and evaluated in-situ. The techniques uses innovative step frequency GPR hardware together with new data collection and data processing methods to provide high-resolution images of in-roadway sensor features. Recent work by the proposed research team has already demonstrated im ...

To build a climate-smart and resilient nation, we need to foster a climate-literate public that understands its vulnerabilities to a changing climate and makes informed decisions. A core component of this challenge is to develop simple, intuitive and high-impact visualizations of climate data--data that is and will be made available through the President’s Climate Data Initiative--for education ...

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

Highway‐rail grade crossings, at which there is an abrupt change in the level of the road surface as it crosses the tracks, present a severe hang‐up risk to vehicles with low ground clearance. In Phase I, ATR developed a conceptual design for a Low Ground Clearance Vehicle Detection System (LGCVDS) to actively prevent such accidents. The LGCVDS functions by measuring vehicles on approach to th ...

To mitigate the Dilemma Zone (DZ) problem, Intelligent Automation, Inc. (IAI) team proposes an innovative Detection, Control and Warning System (DCWS). In this proposed Phase IIB work, IAI team will deploy and evaluate an enhanced version of DCWS that was designed in earlier phases. DCWS provides vehicle-specific dilemma zone protection based on travel time to the intersection as opposed to more c ...

In phase I, a concept to detect, recognize, compute depth, and map utilities and underground infrastructure was demonstrated at traffic speeds with advances in step-frequency ground penetrating radar (SF-GPR). The description of the proposed non-destructive evaluation method was based on first principles to estimate the extent of penetration of a three-dimensional SF-GPR signal into the roadway fo ...
