Split Rules are applied when a Linear Reference System Transaction or Finest Partition process splits a record (e.g., a record is split because a new route is created on the second part of the record). The following are the available Split Rules:

• Don't split: Any value that neither varies as road section width varies nor is affected by road section length changing typically would not be split. An example would be average elevation of a road section.
• Split across: Any value that varies as road section width varies, but is not affected by road section length changing typically would be split across. An example would be pavement width pertinent to this record.
• Split along: Any value that varies as road section length varies, but is not affected by road section width changing typically would be split along. An example would be roadway length.
• Split along and across: Any value that varies as road section area varies typically would be split along and across. An example would be cost to maintain a road section.
