DUE TO THE DETERIORATION OF THE U.S. HIGHWAY SYSTEM'S PAVEMENTS AND BRIDGES, CONSTRUCTION REHABILITATION HAS BECOME A LARGE SCALE EFFORT. ONE OF THE SAFEST AND MOST EFFICIENT TECHNIQUES FOR TRAFFIC CONTROL DURING REHABILITATION OF DIVIDED HIGHWAYS IS TWO-LANE TWO-WAY OPERATION (TLTWO). IN THIS TECHNIQUE, ONE SIDE OF THE HIGHWAY IS CLOSED OFF FOR REPAIR WHILE THE OTHER IS PUT INTO TLTWO WITH CHANNE ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

THE HYDRODYNAMICS AND FLOW-STRUCTURE INTERACTION ASSOCIATED WITH SCOURING AROUND BRIDGE PIERS IS A COMPLEX AND CHALLEN- LENGING PROBLEM FOR HIGHWAY ENGINEERS. THE HYDRAULIC LABOR-ATORY MODEL STUDY IS A PRACTICAL AND RATIONAL WAY TO BETTER UNDERSTAND THE COMPLEXPHENOMENA AND TO HELP SOLVING THE DESIGN PROBLEM IN CONNECTION WITH SCOURING . THE MAIN OB JECTIVE OF PHASE I WORK IS TO DESIGN AND FABRICA ...

INTEGRATED DAMAGE CONTROL SYSTEMS (IDCS) HAVE THE POTENTIAL TO IMPROVE MONITORING, DECISION-MAKING, AND RESPONSE TO SHIPBOARD EMERGENCIES. ULTIMATELY, IMPLIMENTATION OF THESE SYSTEMS MAY REDUCE MANPOWER. THE TECHNICAL OBJECTIVE OF PHASE I WILL BE TO PROVIDE THE USCG WITH SEVERAL DESIGN CONCEPTS FOR INSTALLING IDCS ON USCG SHIPS. THIS WILL INCLUDE ALTERNATIVES FOR HARDWARE AND SOFTWARE AS A FUNCTIO ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

THE PURPOSE OF THIS STUDY IS TO PROVIDE A SYNTHESIS OF RE- CENT EXPERIENCE WITH TRANSPORTATION SYSTEM MANAGEMENT (TMS) AND PARKING MANAGEMENT STRATEGIES, AND ENABLING POLICY IN- STRUMENTS SUCH AAS TRIP REDUCTION ORDINANCES AND DEVELOPER AGREEMENTS IN SUBURBAN CONTEXTS. BASED ON LITERATURE REVIEWSAND FOCUSSED INTERVIEWS OF KEY PROGRAM OFFICIALS AT SITES RESEARCHERS, EVALUATORS AND PRIVATE INTEREST ...

SIGNIFICANT IMPROVEMENTS HAVE BEEN MADE TO TRAIN ALERTER DEVICES SINCE THE INCEPTION OF THE "DEAD-MAN PEDAL." THERE CONTINUES TO BE ROOM FOR ADDITIONAL ENHANCEMENTS, PARTICULARLY IN LIGHT OF TECHNOLOGICAL ADVANCES IN THE FIELD OF ERGONOMICS AND HUMAN FACTORS. ONE AREA OF POSSIBLE IMPROVEMENT LIES IN THE RESPONSE THAT THE DEVICE REQUIRES FROM THE LOCOMOTIVE ENGINEER. DEVICES CURRENTLY IN USE HAVE B ...
