Rail vehicle distance traveled measurements don't currently meet the precision requirement of 5ft./mile.  An innovative microwave technique is proposed using two X band transceiver assemblies separated by a known distance.  Reflected energy from metal objects such as tie-plates or dielectric contrast between ties and rail bed are used as replicate pairs to measure the time passage betwee ...

Research is proposed to develop a locking mechanism for intercity (Amtrak) rotating seats that can be retro-fit to existing seats. Current intercity rail seats, according to the National Transportation Safety Board (NTSB), present a safety hazard to the riding public. Post accident investigations show that passenger rail seats were found to have been uncontrollably rotated even though current se ...

The TEXAS Model for Intersection Traffic is a high-quality single-intersection microscopic traffic simulation model developed at The University of Texas at Austin. It analyzes in sub microscopic detail the behavior of driver-vehicle units as they go through an intersection and intermix with other traffic flows. It has detailed intersection geometry, path following, microscopic car following, lan ...

During Phase 1 of the project, Sharma & Associates, Inc. developed a concept for high speed freight truck intended for 70-ton, regular freight and bi-modal operation, at speeds up to 150 mph. The truck uses a rigid frame and an indpendent, compliant, primary suspension for its basic architecture. Constant contact side-bearings and yaw dampers were also added to improve dynamic performance. Vehi ...

The Advanced Traffic Controller (ATC) goal of a standard open architecture for traffic engineering applications will be more fully realized by the transition from proprietary operating system to open source Linux. In Phase I of this project, Precision Traffic Systems (PTS) demonstrated that a real time Linux OS could support an existing traffic signal control application, and perform to 2070 task ...

The goal of this project will be to develop a prototype voice-activated cockpit (VAC) that will allow a pilot operating in marginal VMC to manipulate controls via voice commands and receive voice feedback for verification of settings. In so doing, we strive to create a system where tasks usually accomplished by looking at an item and manually entering data, turning knobs,, or pushing buttons will ...

As the OPS performs audits of the pipeline operators, pursuant to the Pipeline Safety Improvement Act of 2002 and Sub-part O of the newly released 49 CFR 192, the focus is no longer on the existence of a plan, rather, it is on the existence of a process, the completion of tasks defined within those processes and the documentation that supports and/or defines the decisions associated with said acti ...

The goal of the Advanced Traffic Controller (ATC) program to create an open-architecture general computation platform for traffic engineering applications will be more fully realized by the transition from proprietary operating systems to open source Linux. The use of hard real-time Linux will maintain current levels of operational performance while enabling the use of newer and more powerful har ...
