Abstract
Various methods and systems are provided for predicting crossing times. In one embodiment, a method comprises determining a vehicle position of a vehicle from sensed data, filtering the vehicle position, determining vehicle velocity based on the filtered vehicle position, filtering the vehicle velocity to a greater extent than vehicle position is filtered, at least above a threshold frequency, and determining a time-to-crossing based on the filtered vehicle position and filtered velocity.
