Task 1 - Develop NASS Analysis Tool for Fire and Fuel Leakage Cases

The following summary files have been generated from the NASS summary tool under development.  In each file, a summary has been provided, with relevant crash variables, for all cases of fire and/or fuel leakage occurrence from NASS/CDS.  Due to the size of the files, cases have been divided by NASS reporting year.

1997 NASS Case Summaries [31.3 MB]

1998 NASS Case Summaries [28.4 MB]

1999 NASS Case Summaries [27.5 MB]

2000 NASS Case Summaries [27.2 MB]

2001 NASS Case Summaries [25.6 MB]

2002 NASS Case Summaries [32.8 MB]

A crash query and case summary reporting tool is currently under development to help researchers review historical crash cases collected through NASS/CDS. The web based query page will allow a user to select a specific subset of crashes from the database based on desired crash conditions. Further work is required to enhance the capabilities and usability of this tool as it pertains to fire/fuel leakage variables. In general, a user will perform a query based on a series of limiting conditions. Based on this selection, two information types will be returned. First, data relating to the generated subset of crashes will be available for download to the user in tabular form. Since a large set of crash variables may be returned, a user will then be able to perform sorting and scanning on the data to look for trends and relationships between variables not evident during the initial query. The second piece of information to be returned is a list of all cases that meet the query criteria. A user may then select a case for further investigation. Following case selection, an automated summary sheet(s) will be generated with significant crash variables presented along with applicable pictures and scene diagram. An advance query option will be developed tallow users to select more specific crash descriptors, which will include all fire-related descriptors under this research project. Additionally, the returned information does not include all variables available from NASS/CDS. An interface will be developed tallow the web user to tailor the returned information to suit their application. A graphical representation of the damage and intrusion profiles based on CDC will be generated as well.
