What is CRASH OLDMISS, the Missing vehicle Algorithm?
Since the late 70’s, NHTSA, as part of their NASS statistical studies of collisions throughout the nation, has done research on trying to reconstruct a collision when there is a missing vehicle. The most recent publication on the topic by NHTSA was called The Missing vehicle Algorithm (OLDMISS]) Ref...

What is the Calspan Driver study?
in 1974 Rice and Del'Amico published a study entitled " An Experimental Study of Automobile Driver Characteristics and Capabilities " Calspan Report No. ZQ-5208-K-1. The study included approximately 100 drivers driving one or two test vehicles in five trails through a continuous course con...

What is RICSAC?
Research performed in the 1970's to “locate, review, decipher and place in useable form available experimental data on the structural crush properties of automobiles, and on the spinout trajectories produced by measured collision conditions” [1] revealed significant limitations in the available docu...

What is Validation for vehicle to vehicle collision models?
For convenience here's a quick link to the latest post in this topic For vehicle to vehicle collisions methods validation, obviously cars are mass produced and so full scale tests can be performed from which validations of computer models can be ascertained ( RICSAC tests, etc). There was a group a...

Validation for Occupant Simulation?
Q: I just happened across a copy of the Declaration of Brian G. McHenry in the Washington v Sipin case on the internet and I wanted to find out more about the proposed Validation Index by the Human Biomechanics and Simulation Standards Committee you mention in item 7-e . Can you steer me to the reco...

How does SMAC determine the DeltaV and PDOF?
As part of our research for SAE paper 97-0961 RICSAC-97-A Reevaluation of the Reference Set of Full Scale Crash Tests, SAE Paper 97-0961" we included documentation of the techniques for determination of the DeltaV and PDOF in SMAC and how that compares to the DeltaV and PDOF measured in full-sc...

What is the SMAC Inter-vehicle friction coefficient?
Q: What range of values should be used in SMAC for inter-vehicle friction? A: From our SAE paper 970947 SMAC-97 : "The Inter-vehicle friction coefficient of the SMAC collision model ( AMU, SMAC input card 13, field 7 ) is based on coulomb friction. Coulomb friction is independent of the sliding...

Center of Turn on projection of the rear axle?
Q: According to Gillespie, the center of the turn must lie on a projection of the rear axle, with the radius of the curve through the center of gravity of the vehicle. The perpendicular of both front wheels also must also pass through the center of the turn. A: In real cars, at low speed the rear wh...
