Learning-Based Speed Estimation from Accelerometer-Only Inertial Sensing

Researchers have proposed a model called CarSpeedNet that can estimate the speed of a vehicle using only data from a smartphone's accelerometer without needing any additional sensors. The model was tested on over 13 hours of real-world driving data and achieved an average error rate of around 0.7 meters per second when given a window of 4 seconds of acceleration data. The study also explored how the length of the input window affects the accuracy of the estimates.
