Abstract

PURPOSE: To provide an acoustic method for monitoring residual distance, intended for use in operation of snow removing vehicles, according to which the driver of the vehicle is informed, with progressively changing sound, of the travelling distance after passing through a given point located a predetermined distance apart from snow-removing operation interrupting regions such as tunnel or railway crossing, whereby snow-removing blades of the rotary or Rassel snow-plow can be retracted immediately before the operation interrupting regions.
