| Research projects are conducted under an
overall plan to meet Agency goals. To enable tracking the status of on-going
research projects, summaries are provided here and will be updated quarterly. The project summaries are being added as they become available and most are expected in the near future. Each summary contains the name of project leader(s) and appropriate e-mail address and/or phone number, if you wish to contact someone for further information. It's planned that at some point the summaries will be searchable. General questions regarding this page should be directed via Internet e-mail. |

CRASH AVOIDANCE |
| Intelligent Transportation System (ITS) Program |
| Over the past five years a substantial effort has been accomplished to lay the foundation for continuing research and development of collision avoidance systems. Extensive analysis of accident data was performed to define collision problem areas and causal factors. Based upon these, and other considerations such as related human factors research activities, projects were initiated to develop performance specifications for countermeasure systems and progress has been made in the development of new research tools. In the next five-year period NHTSA will continue research to increase the understanding of system performance levels for collision avoidance products and systems; the degree to which these products can be successfully used by drivers, users' perception of usefulness in improving their driving safety; and the potential for market acceptance, considering factors such as performance, usability, and product cost. Finally the overall benefits to be derived from introduction of CA products will be estimated and refined based upon the above factors. Each of the projects in the program provide specific input to improving the overall knowledge base and understanding of systems that address one or more problem areas. The program areas being addressed in the program are: |
| Intersections are among the most dangerous locations on U.S. roads. Approximately 1.95 million crashes occurred at intersections in 1994 (30 percent of total crashes), causing over 6,700 fatalities and significant numbers of serious injuries. There are more intersection collisions than any other crash type. However, it is also more technically challenging to prevent this type of crash with detection and warning technology than other crash situations. Because of these technical challenges, this is viewed as a longer term program area, but one with potentially large safety benefits. |

CRASHWORTHINESS |
| Vehicle Safety |
| Research program to develop one or more test procedures which evaluate door latch integrity. |

| To provide the technical foundation for an upgrade of existing FMVSS No. 301, Fuel System Integrity. |
| To insure a minimum level of integrity for the fuel containers and systems of vehicles powered by compressed natural gas (CNG), liquefied petroleum gas (LPG or propane),liquefied natural gas (LNG), hydrogen, and other alternative fuels, excluding electric. |
| To explore the potential for reducing injuries by eliminating incompatibilities, both structural and geometric, between passenger vehicles and their potential collision partners. |

| Occupant Protection |
| At the current time integrated seats are tested with both FMVSS NoS. 207 and 210 static loads, but a strut is added to support the seat back. This test procedure only tests the seat attachment points to the vehicle and the seat belt anchorage attachment point, but not the seat back itself. A petition was received asking NHTSA to modify the current regulations to incorporate a more realistic test procedure for integrated seats. This document contains the details of the research planned to investigate the need and modifications that may be necessary to address this concern. |
| To provide support for the potential upgrade of FMVSS No. 213, in an effort to increase safety for children in child restraint systems, thereby reducing the number of children killed or injured in motor vehicle crashes. |
| To provide near term support to the Office of Safety Performance Standards (SPS) for responding to petitions received by the agency regarding seat back strength. |
| Provide the basis for the development of improved occupant protection devices beyond the scope of those currently used in motor vehicles today. |
