Equation Directory for the Reconstructionist
Equation Directory for the Reconstructionist
by Daniel J. Parkka
This book puts over 550 crash reconstruction formulas right at your fingertips! With the Equation Directory for the Reconstructionist, you can quickly and easily locate a formula that solves for a needed unknown variable when other variables are known.
Here’s how it works. The Table of Contents lists the specific categories used in crash reconstruction. Simply find the category for which you need an equation and turn to the page number indicated. Not only does the author, Daniel Parkka, reveal the possible equations associated with the topic, he explains what value will be returned by that particular equation. In addition, he lists all of the variables used in each formula as well as the unit of measure that should accompany the solution.
Listed below are the categories included in the book:
- Acceleration/Deceleration Factor and Rate
- Braking Efficiency
- Center of Mass
- Collinear Avoidance
- Collinear Collision Damage
- Distance
- Energy
- Force
- Grade and Superevelation
- Gravity
- Heavy Truck Impact
- Lane Change
- Mass
- Momentum
- Motorcycle Impact
In addition to the formulas, Mr. Parkka includes tables to help you understand the different variables that may be used in an equation, depending on the traffic crash situation. For example, in the Pedestrian Impact chapter, you will find the following tables: Pedestrian Walking Velocities, Pedestrian Velocity as a Function of Approaching Vehicle Proximity, Pedestrian Accelerations and Sliding Pedestrian Deceleration Factors.
The directory is not intended to be an instructional text; rather, it simply groups equations generally used by reconstructionists and puts them in one location. The directory will also be useful when verifying computer program calculations.
Daniel J. Parkka is a traffic crash reconstructionist who has received state-of-the-art training in his profession. He currently manages his own crash consulting business.
