Visual impression of the car weaving within a lane.
The Standard Deviation of Lateral Position (SDLP) is calculated as the standard deviation of the sway around the average position within the lane.

Schematic overview of data removal during a lane switch.
All data between three seconds before until three seconds after a lane switch is removed prior to analysis.
