Relocating overhead utilities to the subsurface can effectively reduce safety hazards on national highways and other aboveground living spaces. A typical underground space is, however, congested with buried utilities especially in an urban environment. The recordings of those underground utilities are, furthermore, often inaccurate, incomplete, out of date, or even entirely missing as a result of ...

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 ...

Traffic congestion on our nation’s transportation network poses a major threat to economic prosperity and our citizens’ quality of life. When dealing with traffic congestion, especially the congestion caused by nonrecurring events, proactively managing the traffic signals in the network can be critical in accommodating the drastically varying traffic demands caused by the non-recurrent event, ...

This proposal suggests research on developing the next generation of consumer experience for Usage Based Insurance (UBI) in an increasingly socially connected world while addressing the need to protect privacy. It also proposes research on methodologies to address this from the perspective of insurance actuarial science. It will enhance Agnik’s current consumer and UBI products through the follo ...

Planned or unplanned traffic events, such as work zones, collision accidents, sporting games and stormy/snowy weather, arise along our roadway systems and affect normal traffic operations. These anomaly events cause various magnitude of traffic congestion and safety impact to road users. Thus, local or regional Traffic Management Centers (TMCs) have spent tremendous amount of resources responding ...

Today, urban underground spaces are shared by multiple utility companies for laying power lines, gas lines, water supply/sewage pipes, fiber-optic cables, etc. The recordings of such buried utilities are often erroneous, inadequate, or outdated (if they ever exist) due to insufficient surveying methodologies and as-built recording practices. Ability to accurately locate and provide awareness of bu ...

The Advanced Pavement Evaluation (APE) prototype system combines multiple sensors to detect, measure, and assess the condition of sub-surface features, including in-pavement traffic sensors, pavement structures, and defects or deterioration of such structures. In phase II, the research and development efforts produced two distinct prototypes solutions: a step-frequency ground penetrating radar (SF ...

The ability to monitor the integrity of a bridge structure and detect damage or condition changes at early stages is of significant importance for bridge operation safety. Currently, the most widely used damage detection methods rely on subjective, incremental visual assessments or localized testing techniques. In this proposal, we propose to develop and test a low cost and efficient bridge stru ...

This research focuses on the development of a real-time signal timing methodology and algorithms that balance safety and efficiency. This research consists of two phases: Phase I was completed in December 2009; it examined the relationships between signal timing and surrogate measures of safety, namely the frequency of rear-end, angle and lane-change conflicts. The FHWA Surrogate Safety Assessm ...

Our approach to aircraft wiring inspection is to inject a special type of low level probe signal into the cable to be tested. The system response to this special input can be used to give the complete transfer function of the cable. Incipient failures in the cable will be detectable as subtle changes in that transfer function, or cross-correlation between probe input signal and response, includi ...
