RF Viper is a novel next generation system to stop wrong-way drivers (WWD) on ramps. It is the “vehicle-to- infrastructure” missing component of the current Alert & Warning systems installed in many states. Like a true viper that uses its fangs to inject venom and incapacitate its prey, the RF Viper emits energy that interrupts vehicle engine electronics, stops the engine, incapacitating the v ...

Most research on scour assessment has traditionally focused on developing best-fit or envelope equations to estimate the maximum scour depths from physical experiments in a laboratory environment. However, obtaining an accurate estimate is always a challenge due to numerous uncertainties in the actual riverine or coastal environment. With advances in new surveying technologies and growing computat ...

A newly proposed combination of high-strength weathering steel sheet with Ultra-High Performance Concrete (UHPC) to leverage the benefits of both emerging technologies. The combined system offers benefits over traditional orthotropic steel decks and existing concrete or UHPC deck solutions, both of which offer high up-front costs in fabrication or forming. The resulting composite structure provide ...

This Small Business Innovation Research (SBIR) Phase I project will investigate the value of a quantitative risk assessment tool for management of geohazard threats to pipelines.Phase I will determine data sources for quantitative risk assessment to support management and decision-making needs of pipeline industry stakeholders; identify the potential market for such a tool; identify a study locati ...

In-line inspection (ILI) is a cornerstone for pipeline integrity. Advances to ILI tools are essential to maintaining pipeline safety. Gaps exist for the detection of circumferential cracking (at and away from welds and dents) and bending stresses. Few technologies exist that can make reputable claims for stress measurement that are non-destructive, reliable, and appropriate for integration onto an ...

PHMSA reports a total of 5,745 pipeline incidents with 282 deaths and 1,193 injuries in the 20-year period from 2000 through 2019. Moreover, these incidents cost $10,419,311,449 in damages. Most oil and gas (O&G) transmission pipes are repaired externally by excavating around a damaged or leak site, preparing the pipe surface, and mechanically installing a repair product such as a clamp or wrap on ...

Crushed aggregates play an important role in the safe and reliable operation of our nation’s railroad infrastructure.Over time, aggregates become fouled by finer particles, and if not monitored and remedied, this fouling can lead to catastrophic accidents such as train derailments.A handheld inspection system that can accurately perform a quantitative measure of aggregate gradation and degree of ...

The objective of the proposed Phase I Department of Transportation/Federal Highway Administration SBIR program is to develop a sprayable highway paint to communicate vehicle-to-everything (V2X) safety messages between infrastructure, vehicles and pedestrians. During Phase I, NanoSonic will work with Virginia Tech antenna designers and the Virginia Tech Transportation Institute (VTTI) to design and ...
