Curing concrete properly is essential for strength gain and durability. While the importance of curing is widely known, all too often curing is not properly executed in practice. This proposal outlines a sensing system that will have three functions: · to record the weather conditions during the concrete placement. · to document how the implemented curing impacts a known concrete system. · to p ...

Innovative and low cost methods for concrete bridge deck assessment are sought to implement in the Long-Term Infrastructure Performance (LTIP) programs. The new evaluation tools and methods to be used especially in field data collection must exhibit certain features such as elimination of traffic lane closures, assessment of bare concrete bridge decks as well as decks with overlay, reduced number ...

Design Interactive, Inc. (DI) proposes development of Greenlight, a readiness assessment technology designed to objectively measure drivers’ alertness before operating a commercial motor vehicle (CMV). Greenlight also provides tools for improving readiness by mitigating fatigue via monitoring and managing stress. This capability will contribute to an overall reduction in crashes due to drowsy dr ...

Connected automated vehicle (CAV) technology has significant implications in terms of transportation system safety and efficiency. However, building and maintaining a wireless communication infrastructure (e.g. roadside units (RSUs), power, fiber optic lines etc.) across the U.S. is a challenging task. In urban areas, where vehicle population and vehicle-miles-traveled (VMT) are high, building suc ...

New developments in tools for exploitation of stereo aerial photography now enable desktop Windows applications capable of interfacing with existing GIS databases. One area of potential use for these tools is in the area of Highway Access Management especially as it relates to improvement in the process for Highway Driveways. Research is proposed to determine system requirements for using a digi ...

Lack of transportation access affects approximately 30% of people with functional limitations. In fact, people with functional limitations experience transportation access barriers four times more than those without limitations. With the emerging market of low cost augmented and virtual reality technology, perceptual user interfaces (PUI) that interact more naturalistically with end-users are prov ...

The Surface Transportation and Uniform Relocation Assistance Act requires the use of native grasses and wildflowers within highway corridors. A major problem for the revegetation industry has been the ability to predictably establish native vegetation from seed. The production of native sods would allow for the most sensitive period of establishment-germination and initial seedling growth-to be ...

During the Phase I SBIR Effort, Mainstream demonstrated a unique vehicle monitoring system (VMS) for tractor trailer applications. The development was driven by the need to easily store, retrieve, and transfer key trailer parameters to the tractor and the need to electronically transfer key driver, tractor, and trailer information to roadside inspectors and maintenance personnel. In Phase I, we ...

This project will use an ultrasonic beam traveling logitudinally along the rail rather than the complex normal and angle-beams transducer assemblies in current systems. Detectio of transverse defects becomes a simple pulse-echo application and resolves many inherent speed, inspectin reliability and robustness problems in current rail inspection systems. The simplified procedure will increase the r ...

According to a recent survey, 178 million trips are taken across U.S.’s 46,000 structurally deficient bridges every day. Due to concerns over their actual load-carrying capacity, some of these bridges have posted weight and speed restrictions. The lack of enforcement of these load postings is an issue nationwide and presents risks for human lives and costly failures. To address this issue, this ...
