The following new research studies reported by the Federal Highway Administration's (FHWA) Office of Research and Development are sponsored in whole or in part with federal highway funds. For further details on a particular study, please contact Richard Richter, (703) 285-2134.
NCP Category A -- Highway Safety
A.5: Highway Safety Design Practices and Criteria
Title: Implement, Test, and Evaluate DYNA3D/ NIKE3D Model for Safety Analysis
Objective: This contract is an interagency agreement with the Lawrence Livermore National Laboratory to develop and/or modify vehicle, dummy, and barrier models and to validate their performance against crash data. Existing crash data will be used where possible, and a limited number of new crash tests will be conducted. At the present time, four agencies are collaborating on this effort to modify the DYNA3D/NIKE3D finite element model developed at LLNL to accurately simulate vehicle crash impacts. The participating organizations are the: (1) Federal Highway Administration, (2) National Highway Traffic Safety Administration, (3) Transportation Research Board, an agency of the National Academy of Sciences, and (4) LLNL, a national defense laboratory. LLNL will apply a computer technology, previously used to simulate nuclear explosions and to simulate intercontinental ballistic missiles impacting hardened missile silos, to simulate vehicle crashes into other vehicles/roadside objects and to simulate occupants impacting vehicle interiors/belts/air bags.
The improvements in motor vehicle safety over the past few years have largely been obtained through advancements in resolving the more straightforward engineering problems associated with motor vehicle and roadway design. The safety issues remaining are far more complex and require the application of state-of-the science computer simulation technology and tools. It is envisioned that ultimately this effort will lead to broader collaboration of government, industry, and private organizations including the state DOT research agencies, the U.S. motor vehicle manufacturers, and national and local safety groups with engineering competence.

B.2: Advanced Traveler Information Systems
Title: Electromagnetic Compatibility Testing for IVHS Systems
Objective: The objective is to establish a resource to conduct evaluations of the electromagnetic compatibility of various proposed IVHS communications components, operating singly and in combination. Many of the issues to be investigated will be drawn from the IVHS system architecture development effort. Sophisticated simulations, anechoic chambers, and antenna test ranges will be employed to perform this testing. Testing will be performed on a task order basis.

Expected Completion Date: May 1994
Estimated Cost: $36,500
Title: Development of a National Automatic Vehicle Identification Standard
Objective: This study will first determine the services to be provided by automatic vehicle identification and the requirements of a system to provide those services. Existing systems and standards will then be reviewed to determine how they meet these requirements. Based on this review, a proposed national standard will then be developed. Finally, a prototype system will be developed to demonstrate the feasibility of the proposed standard.
Contractor: National Institute of Standards and Technology Expected
Completion Date: December 1993
Estimated Cost: $266,964
NCP Category C -- Pavements
C.6: Long-Term Pavement Performance Evaluation
Title: Electrochemical Bridge Protection
Objective: This work continues Strategy Highway Research Program study C102. Florida will purchase/fabricate a solar-powered, intermittent cathodic protection system and will install it on the Howard Franklin Bridge on I-175 over Tampa Bay. Texas will purchase/fabricate the necessary null probes to be installed on Port Isabel Causeway on Queen Isabella PR100 on Padre Island. Virginia will purchase/fabricate the necessary null probes to be installed at structures #2900 and #2901 on I-95 over the Rappahannock River in Stafford County.
Contractor: States of Florida, Texas, and Virginia
Expected Completion Date: March 1994

NCP Category D -- Structures
D.1: Bridge Design
Title: Advanced Composite Cable-Stayed Bridge Systems Development
Objective: The objective of this project is to develop alternative bridge systems for a cable-stayed freeway crossing over I-5 at the University of California at San Diego. This detailed bridge systems development is an independent and necessary step to provide a detailed technical plan for any first application of advanced composite materials and technologies in a cable-stayed bridge structure.
Contractor: University of California

Estimated Cost: $1,600,000
D.3: Hydraulics and Hydrology
Title: Scour Performance of Bridges During Floods
Objective: This project extends the existing agreement with the U.S. Geological Survey to collect field data on bridge scour. Work includes planning and coordinating field data collection by state district personnel, assembling field crews to collect data during floods for areas that do not have cooperative studies, maintaining a repository of field data, and developing prediction equations from a national perspective.
Contractor: U.S. Geological Survey

NCP Category E -- Materials and Operations
E.3: Geotechnology
Title: Solid Waste Processing for Engineering Use in Infrastructure Construction Materials
Objective: This study will determine the feasibility of using recycled plastic in highway construction. Environmental agencies are establishing policy to eliminate the current practice of waste disposal. At this time, municipal authorities are unable to cost-effectively reduce the amount of landfill waste. During the last several years, state highway agencies (SHAs) successfully used some waste materials in highway construction. Many SHAs are now proposing to use recycled plastics. This investigation is part of an overall effort to develop innovative highway construction materials.
Contractor: Polytechnic University, Brooklyn, New York
Expected Completion Date: December 1993
Estimated Cost: $25,000
Title: Development of Piezocone for Use in Centrifuge Testing and Validation of Methods for Interpreting Cone Penetration
Objective: In recent years, the Cone Penetrometer Test has proven to be extremely useful in determining in situ soil profiles and properties. However, there is a need to develop a sound theoretical model to validate empirical relations currently being used to interpret field data. This investigation will conduct the CPT in the centrifuge on soil samples and compare the results to soil properties measured by conventional laboratory tests. An experimental data base will be developed to formulate a theoretical CPT model to evaluate existing CPT interpretation methods
