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 ...

Williams-Pyro is developing an AccuTag Miniature Surveillance and Tracking System (Accu-MiSTS). Accu-MiSTS employs cluster management techniques and ad-hoc networking to provide a readily scalable architecture with which to perform comprehensive surveillance. A cluster comprises one supernode and up to 65,536 nodes, all of which are within the communication range of at least one other node. The Ac ...

A novel third rail insulator cleaner and novel cleaning tool - the Spin Wedge, will be developed. The novel cleaner is a skate that rides directly on the third rail and is attached to a service vehicle. Four Spin Wedges, attached to the skate, direct a very rapid series of high pressure water jets arcs, like hammer blows, only on the surface to be cleaned. As the skate moves forward at high spe ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

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 ...

DUE TO THE DOWNSIZING OF AUTOMOBILES ON U.S. HIGHWAYS, MINI-CARS HAVE BECOME A MAJOR PART OF THE AUTO POPULATION. THE LIGHT WEIGHT AND HIGH CRUSH RATE OF THESE VEHICLES CAN CAUSEHIGH VELOCITY CHANGE LEVELS WHEN IMPACTING MOST EXISTING BREAKAWAY LUMINAIRE SUPPORTS. THIS INCREASES THE PROBABILI-TY OF INJURY TO OCCUPANTSOF MINI-CARS WHEN IMPACTING LUMI- NAIRE SUPPORTS. CONCEPTS HAVE BEEN DEVELOPED WH ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

This research is designed to develop a methodology that will identify unsafe traffic conditions such as rear-end, angle and left-turn crashes at individual signalized intersections, and in arterial and grid signalized networks. This research project will have a final product in the form of an algorithms, that would be developed to alleviate such safety risks by adjusting controller timing and ope ...

AN IBM PC-COMPATIBLE AIR TRAFFIC CONTROL SIMULATOR WITH VOICE I/O, AN EXTENSIVE DATABASE OF GEOGRAPHICAL FIXES, AND CONFLICT RESOLUTION VIA AN EXPERT SYSTEM IS PROPOSED. THIS SIMULATOR WILL BE DESIGNED TO FACILITATE AIRSPACE DESIGN ANDPROCEDURE DEVELOPMENT. CAPABLE OF DISPLAYING A REALTIME RADARSCOPE PICTURE OF ANY GEOGRAPHICAL AREA, ITS SECTORS MAYBE CREATED VIA A SIMPLE USER INTERFACE BY FIELD P ...
