Overview

This Function shall be capable of providing the following facilities:

(1) A HMI that enables the Travel Information Operator to have access to the contents of the stores of Road Trip Planning Data and PT Trip Planning Data.
(2) The ability for the Operator to review and update the data in the stores including the provision of static data for the urban and inter-urban road networks car parks and service areas, where this is not available from the Manage Traffic Functional Area.
(3) The ability for the Operator to obtain reports on the current contents of the stores, including in particular details of any active events or incidents that are affecting Travellers trip plans.
