Hydroplaning and Accident Reconstruction

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">Automobile hydroplaning speed is affected by both the vehicle load on the tire and its inflation pressure, yet only inflation pressure is used in Horne's (1968) equation. He later (1984) made modifications to include a vehicle's tire footprint characteristics. Dunlap et al.

Accident reconstruction methods

Vehicle System Dynamics, 2009
While reconstructing a car accident, there are several questions that must be answered, such as the movement of all the vehicles involved or of other people involved, or of objects from the point of first visual contact to their rest positions. Time history of velocities, positions as well as crash-related data such as velocity changes, deformation ...

Automated Accident Reconstruction

SAE Technical Paper Series, 1975
<div class="htmlview paragraph">The Simulation Model of Automobile Collisions (SMAC) computer program was developed by Calspan Corporation as an aid with which to accurately reconstruct road accidents. Part of the overall objective of the research has been to make the system “user oriented” so that users without an engineering background can ...

Sensitivity of Accident Reconstruction Calculations

SAE Technical Paper Series, 1998
<div class="htmlview paragraph"><i>A number of simplistic formulae, based on particle dynamics, energy, and momentum methods are routinely employed by accident reconstructionists to calculate vehicle speeds immediately prior to impact. It is almost always the case that scene evidence and other information regarding important variables ...

Accident Reconstruction in Urban Areas

SAE Technical Paper Series, 1978
<div class="htmlview paragraph">An urban area is an excellent laboratory to conduct vehicle accident investigations. The central city of Los Angeles, California and the entire city of Miami, Florida, will be the geographical areas discussed. These areas experience a large number of accidents in a relatively small geographical region and contain ...

Presentation Tools for Accident Reconstruction

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">A graphic artist with training in engineering and the sciences can be an essential member of the accident reconstruction team. With his general technical knowledge and his experience with visual presentations, he can provide the reconstructionist with valuable support in preparing presentations for lay or technical

The Application of Photogrammetry to Accident Reconstruction

SAE Technical Paper Series, 1986
<div class="htmlview paragraph">Accident investigation involves the collection of relevant data from many sources. Frequently, information exists in the form of accident photographs of objects that are no longer available for examination or direct measurement.

Structural reliability of road accidents reconstruction

Forensic Science International, 2013
Reconstruction of road accidents combines objective and subjective action. The former concerns science, the latter assessment of human behavior in the context of objective findings. It is not uncommon for experts equipped with an arsenal of tools to obtain similar results of calculations, but to present radically different conclusions about the cause ...

Calculation reliability in vehicle accident reconstruction

Forensic Science International, 2016
The reconstruction of vehicle accidents is subject to assessment in terms of the reliability of a specific system of engineering and technical operations. In the article [26] a formalized concept of the reliability of vehicle accident reconstruction, defined using Bayesian networks, was proposed.

Crash Phase Accident Reconstruction

SAE Technical Paper Series, 1986
<div class="htmlview paragraph">Two algorithms, CRASH and IMPAC, used to calculate crash delta-V and impact velocity are compared. Each is observed to have common features but important differences. Error sources from restitution and intervehicle friction are discussed.
