Abstract
A method and system for controlling a speed of a vehicle. Acceleration data comprising acceleration samples of the vehicle on a segment of the road is captured. Jerk energy values associated with the vehicle on the segment is computed based upon the acceleration samples. Median jerk energy of the vehicle on the segment may be determined based upon the jerk energy values. Predictive median jerk energy of the vehicle on the segment is computed using a statistical equation. A score associated with the segment is calculated based upon the median jerk energy, the predictive median jerk energy, and a standard deviation (σ). The segment is classified into one of a first set of categories and a second set of categories based upon the score. A feedback signal indicative of controlling the speed of the vehicle is transmitted to a controller based upon the classification.
