Entree is a data entry and validation application, for the Microsoft Windows 7 platforms, developed for the express purpose of assembling data-rich crash test data sets. The NHTSA Office of Crashworthiness Research is making this software available to its contractors, test sites, and the public in order to facilitate the receipt, processing and exchange of this data.

Entree for Windows version 5 (V5.15.4.15) is released to the public!

This update adds new features below:

Add a button named "Check Curve Related Error' and a read-only message box in the bottom of 'Instrumentation' page to check errors of curve data and curve-related fields: 'First Point' (NFP), 'Last Point' (NLP) and 'Time Step' (DELT). If errors are found, error-related fields will be highlighted and a suggestion will be displayed in the message box. Once hitting button named "Check Curve Related Error', all curve data and their related fields will be scanned and identified; a table recording related possible errors will be generated; the button named "Check Curve Related Error' will be changed to "View Curve Related Data" for displaying possible errors. The error message in the pop-up view of curve related error will be updated after every correction. This new feature is optional. Therefore, users can run the software as ever to complete editions and validations in all pages without concerning about the curve-related errors and leave the corrections and validations for curves in the final step.
  1. Add new test configurations (TSTCFN) whose code names are 'FCW', 'LDW' and 'ROL' for collision warnings in forward, lane departure and rollover performance tests. Once a collision warning code is selected in the 'Test Configuration' of "General Test" page, the code contents in other pages, especially in the "instrumentation" page, will be narrowed for the collision warning tests only.

An individual download of version of the Microsoft Access Database, Ncodes.mdb, is now available. Many new models are available in this update. This database includes all the code tables used in EntréeV5 and must be placed in the same folder together with EntréeV5.exe. When EntréeV5.msi is downloaded from this web page and installed in a local computer, the latest version of Ncodes.mdb is also installed. On default, the folder is C:\Program Files\NHTSA\EntreeV5. Replacing with the latest version requires system admin privilege.
