The NHTSA NVS R&D is pleased to announce the release of the Signal Analysis Software installers. We look forward to your feedback.


There are two MSI installers for downloading and installing NHTSA NVS R&D software: VSRsofware.msi and VSR_RDDBsoftware.msi. Each installer can automatically install software applications, libraries and relative system files to your computer system, as well as generate a folder containing application shortcuts on desktop. The installer is also an uninstaller, however, installation and uninstallation must use the same installer.

Operating system: 32-bit Microsoft Window 7 professional and up; 32-bit Window 7 Enterprise is the most favorite.


Download Engineering analysis software, VSRsoftware (v5.15.3.31), using local UDS files for impact tests. This installer will install 17 applications:

(1) 208Neck – 208 Neck Shear analysis
(2) AcebulumIlliac – Acebulum-Illiac signal analysis
(3) BwFilt – Filter signal forward and backward with a second order Butterworth algorithm
(4) Clip3ms – Clip 3 ms analysis
(5) CombinedThoracicInjury – Combined thoracic Injury computations and analysis
(6) CompareSignals – Estimate signal similarities
(7) Fir100 – Computations for 100 Hz finite impulse response filtering of digitized time-series signals
(8) HIC – Head injury criteria computations
(9) Intrusion – Intrusion analysis
(10) MadyPlot – Mady signal plotting
(11) Merts – Merts force shear criteria computations and analysis
(12) Nij – Neck injury criteria computations
(13) PlotBrowser – Plot, resample and analyze UDS signals
(14) Resultant – Resultant computations of a set of two or three dimension signals
(15) TibiaIndex -- Tibia moment, force and index computations and analysis
(16) TTL – TTI (Thoracic Trauma Index) computations and analysis
(17) VC – Viscous criterion computations and analysis

Download Engineering analysis software, VSR_RDDBsoftware (v5.15.3.31), remotely accessing data/information from NHTAS R&D database for a single test. Note that the remote-accessing feature of applications with versions earlier than v2.14.6.23 or applications deployed by installers with versions earlier than v14.6.19 has been disable due to a security issue. This installer will install 15 applications:

(1) AnkleRotation – Ankle rotation analysis
(2) AutoInjuryCriteria – Vehicle injury criteria value computations and analysis
(3) CompareTestSignal – Estimate similarities of a set of signals by referencing a signal
(4) CompatibilityEvaluation – Signal compatibility evaluation
(5) FiveStarRating_old – Vehicle five star rating with the old guide.
(6) InjuryAssessmentValue – IAV (Injury Assessment Value) computations for a test.
(7) LoadCellAnalysis – Loadcell analysis for an impact test
(8) MHDFilter – MHD Filtering computations and analysis.
(9) RearImpactInjury – Rear impact injury analysis
(10) ReportGenerator – Generate impact test reports
(11) RoofCrush – Vehicle roof crush analysis
(12) SignalBrowser – IAV computations and analysis for signals in an impact test
(13) SubmarineIndicator – Submarine indicator value computations
(14) ToePanIntrusion – Toe-pan intrusion analysis
(15) VehicleChecker – Check the brief information for vehicle test
