About The Station

A counting station represents how and where a count was taken. A station could describe how a machine or a person has performed the count.

A station will have at least one channel. Each count tally record or observation is related to a channel.

For motorized traffic, a channel is typically a roadway lane. For non-motorized vehicles (bicycles and pedestrians), a channel can be a sidewalk, a crossing or similar.

There are three main header record types that help to define the station:
  • SC: The channel definition record is used to declare channel IDs, direction of travel, and what the counted objects are moving on. Each count tally or observation is related to a channel.
  • SL: The station label is used to provide additional descriptive information about the station, for use in charts and tables.
  • SE: The equipment label is used to provide additional information about the machine performing a count.
Several other "S" header records are available.
