    "Monte Carlo with Excel for Crash Analysis", 2 hours with Wade Bartlett

    DATE: Friday, 15 December 2023
    TIME: 12 noon - 2 pm EDT (GMT-4)
    COST: Free for NAPARS member;  $5 for non-members
    LOCATION: Worldwide Via Zoom

    ACTAR: This event has been approved by ACTAR for 2 CEUs (signing in with i-Attend during the show will be required, so get the new version on your phone in advance)

    Registered attendees will be able to request an  attendance certificate.

    SUMMARY: A review of the technique's background in crash analysis, and a practical step-by-step demonstration of how it's done, including conditional sampling to accommodate data known through EDR or other means.

    The foundations of this discussion will primarily be these four sources:

    1. "Conducting Monte Carlo Analysis with Spreadsheet Programs", SAE Paper 2003-01-0487 

    2. "Monte Carlo Analysis for Accident Reconstruction", Accident Investigation Quarterly, Issue #49, Winter 2008, pg 19-23

    3. "Monte Carlo Analysis of Motorcycle/Automobile Crash", ARJ 18(6), Nov/Dec 2008

    4. November NAPARS Zoom show on Probability and Statistics (The video and ppt handout for which are in the Reference Library)

    ·         What kind of problems can we attack with this tool?

    ·         Why is Monte Carlo different from other ranging techniques?

    ·         How does conditional sampling work?

    ·         Combining Monte Carlo results with other data: EDR, Video, Scene

    ·         Evaluating interactions between variables.
