map_data_store_contents

This data store is used by many processes within ITS functions as a source of digitized data on the physical layout of the road and highway network. It will include three types of data, the digitized map data, the details of each link and the gazetteer that details all road and freeway names. This data will be obtained from a specialist supplier and will be accessed in such a way that the choice of supplier will be left open and up to the individual system operators. The link identity data will be updated on a regular basis. The data store consists of the following data items each of which is defined in its own DDE:

map_digitized_data
+ map_link_identity_data
+ map_gazetteer_data
+ map_transit_data
+ map_hri_data
