AS 1742 is the Manual Of Uniform Traffic Control Devices. Part 5 specifies requirements for the design and use of street name and community facility name signs on all types of roads except expressway type roads. It contains an Appendix D with a list of "Street Types" and the associated abbreviations. It contains a Note: "These abbreviations for street types are for use on street name signs, displayed on streets. When abbreviating street types in any digital exchange or storage system, the abbreviations in AS/NZS 4189 and AS 4590 shall be adhered to." Thus, AS4819 is the appropriate standard for Waze mapping to use. | AS 1742 is the Manual Of Uniform Traffic Control Devices.

We may not need to have official abbreviations for every conceivable road suffix. The current list contains about 170 abbreviations. Based on SA road names, the 10 suffixes Road, Street, Avenue, Highway, Drive, Terrace, Track, Court, Lane and Crescent cover 95.3% of all segments. Adding another 10 (Way, Place, Parade, Grove, Circuit, Close, Boulevard, Freeway, Walk and Expressway) brings the total to 99.2%. If we provided a rule saying "suffixes not appearing in the table should be spelled out in full", we could cut the table down from 170 entries to 18. ("Walk" and "Lane" don't have abbreviations.) If editors followed that rule, we would cut down the incidents of people making up non-standard abbreviations but still get 99% of the benefit of shortened names | We may not need to have official abbreviations for every conceivable road suffix.

Relevant Standards
AS/NZS 4819:2011 covers naming of roads and localities, and recording and mapping the related information. It contains an Appendix A with a list of "Road Types" and the associated abbreviations.
AS 1742 is the Manual Of Uniform Traffic Control Devices. Part 5 specifies requirements for the design and use of street name and community facility name signs on all types of roads except expressway type roads. It contains an Appendix D with a list of "Street Types" and the associated abbreviations. It contains a Note: "These abbreviations for street types are for use on street name signs, displayed on streets. When abbreviating street types in any digital exchange or storage system, the abbreviations in AS/NZS 4189 and AS 4590 shall be adhered to." Thus, AS4819 is the appropriate standard for Waze mapping to use.
The AS4819 entries for LANE, LOOP, MALL, MEWS, PATH, RAMP, RISE, VIEW, WALK, and WAY have been omitted from the table of abbreviations, as their "abbreviation" is the same as the full word, and they are covered by the advice "If no abbreviation is given in this table, then spell out the word in full".
On the frequency of road suffixes:
We may not need to have official abbreviations for every conceivable road suffix. The current list contains about 170 abbreviations. Based on SA road names, the 10 suffixes Road, Street, Avenue, Highway, Drive, Terrace, Track, Court, Lane and Crescent cover 95.3% of all segments. Adding another 10 (Way, Place, Parade, Grove, Circuit, Close, Boulevard, Freeway, Walk and Expressway) brings the total to 99.2%. If we provided a rule saying "suffixes not appearing in the table should be spelled out in full", we could cut the table down from 170 entries to 18. ("Walk" and "Lane" don't have abbreviations.) If editors followed that rule, we would cut down the incidents of people making up non-standard abbreviations but still get 99% of the benefit of shortened names
