More Information

Although the Unsafe Route network is not used in the Tribal School Admissions System, and is currently only a referece file, there are several networks used in the school admissions process:

  • The Designated Route - used for allocating school places.
    Designated route distances are stored against the preferences.
  • Safe route network - used for 'normal' transport measurements.
    This network is derived from our designated route network, with all parts of the designated route network marked as 'unsafe' removed.
    Safe route network distances are stored against the preference > transport eligibility tab > safe walking distance
  • ITN_Admissions - used for low income transport.
    ITN distances are stored against the preference > transport eligibility tab > road distance
