Vehicle Braking Performance: Stopping Distance Fast Track

I.D.# PD230826ON
Access Period: 90 days
Duration: 1 Hours

Stopping Distance is one of the most common metrics of a vehicle's braking performance and one of the most critical attributes of accident prevention and minimization. The measurements are used within the development of the vehicle and are a critical aspect of accident prevention, accident reconstruction, and overall occupant and pedestrian safety management. While the results of this metric are published in a variety of sources, the factors that differentiate vehicle performance, vehicle dynamics, and calculation of the braking performance required to achieve desired performance are not widely available.

In this one-hour online short course, instructor Tom Hall reviews the methods used to measure and report stopping distance. He also analyzes the associated formulations to determine the braking forces created by a wheel brake and necessary to achieve a desired distance. Vehicle and driver contributions to the overall stopping event are examined.

Is this Fast Track for You?
The Vehicle Braking Performance: Stopping Distance Fast Track would be of value to anyone involved in the validation of a braking system, either in the development of the validation plan or the execution of the validation plan. Those involved in accident reconstruction and accident prevention would benefit from an understanding of the techniques, principles, contributing factors and limitations of stopping performance to improved vehicle and road system design. This course would also be of value to those involved in vehicle marketing -- a detailed understanding of the metric's generation and contributing effects will insure that promotion and comparison is done in a qualified manner.
