How fast do heavy trucks accelerate? 

Kineticorp Accident Reconstructionist, Sean McDonough, discusses our latest research “Two Phase Heavy Truck Acceleration Model.” Sean presented the findings at SAE International‘s 2019 World Congress Event (WCX). A special thanks to David Danaher for leading the team on this research and Drew Donaldson for his involvement with the project.

Publication Introduction:

There have been several papers published over the past 25 years regarding the acceleration of heavy trucks, including different loading conditions, drivetrain configurations, and driving techniques. The papers provide a large data set that measures the speed, distance, and time of the vehicles during acceleration testing and present the data in tabular or graphical formats. Although the data as presented can be useful, it can be challenging to pore over all the data to determine the correct set for a specific application in accident reconstruction. As of this paper’s date of publication, there are approximately eight relevant papers with a total of 268 acceleration tests performed, spanning many years. This paper reviews all the available published literature and summarizes the relevant data in a comprehensive list of accelerations for different heavy truck configurations, which provides a valuable resource to the accident reconstruction field. …..
