Dated versions never change. ## Query The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/vic-traffic-volume-aadt-2019/rows. Counts and sums: https://publicdata.au/api/v1/datasets/vic-traffic-volume-aadt-2019/aggregate. - Rows: https://publicdata.au/api/v1/datasets/vic-traffic-volume-aadt-2019/rows?limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/vic-traffic-volume-aadt-2019/aggregate?group=road_name&metric=max.aadt_all_vehicles Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`. - `select`: Fields to return, comma-separated. Every field when absent. - `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent. - `limit`: Rows per page, 1 to 10,000. 100 when absent. - `offset`: Rows to skip. The `next` URL in each answer sets it for you. - `group`: On `aggregate`, fields to group by, comma-separated. - `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent. - `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers. Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions//` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets//versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

Open https://publicdata.au/d/vic-traffic-volume-aadt-2019/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/vic-traffic-volume-aadt-2019/v/2025-06-24/data.csv today. The same path serves Excel, JSON, GeoJSON, Parquet, SQLite, DuckDB, GeoPackage, PMTiles, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same. ### Can I open Annual average daily traffic volume on declared roads, 2019 in Excel? Yes. https://publicdata.au/d/vic-traffic-volume-aadt-2019/v/2025-06-24/data.xlsx is a workbook with the 14,662 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/vic-traffic-volume-aadt-2019/v/2025-06-24/data.csv.gz is the CSV at about a tenth of the size. ### What years does Annual average daily traffic volume on declared roads, 2019 cover? The current version covers the years since 2019. Each release from Transport and Planning becomes a new dated version here, and earlier versions stay online. ### How often is Annual average daily traffic volume on declared roads, 2019 updated? Transport and Planning no longer updates it. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Annual average daily traffic volume on declared roads, 2019 commercially? Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file. ### Is this the official source for Annual average daily traffic volume on declared roads, 2019? No. The publisher is Department of Transport and Planning, and its page is https://discover.data.vic.gov.au/dataset/historical-annual-average-daily-traffic-volume. This site republishes the publisher's file without changing its content. The original sits beside every version as source.geojson with its SHA-256, so the two can be compared. ### What coordinate system does Annual average daily traffic volume on declared roads, 2019 use? The publisher's GeoJSON names no datum, so it is read as WGS84 (EPSG:4326) as the GeoJSON standard sets, and moved to GDA2020 for publication. The GeoJSON file uses GDA2020 as well, which differs from the WGS84 GeoJSON expects by well under a metre. ### What does each row hold? One road segment of the Victorian declared road network in one direction of travel, with the average number of vehicles and of heavy vehicles that used it each day in 2019, as a line in the GeoParquet, GeoJSON, GeoPackage and PMTiles files. ### Are the volumes counted or estimated? Both. The publisher marks each row Actual where the volume comes from a traffic count and Estimated where it was worked out by its own data processes. About one row in six is Actual. ### Why only 2019? The publisher's historical series has one file for each year from 2001 to 2019. This entry holds the 2019 file, the newest in the series. Local roads that councils manage are not in the network it covers. ### What is the percentage of heavy vehicles? The publisher's own share of the daily volume that is heavy vehicles, as a fraction, so 0.07 is 7 per cent. It is published as given. ## What this site did to the data Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.geojson`. ## Improve this dataset This page is built from [register/vic-traffic-volume-aadt-2019.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/vic-traffic-volume-aadt-2019.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
