## 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/qld-traffic-census/rows. Counts and sums: https://publicdata.au/api/v1/datasets/qld-traffic-census/aggregate.

- Rows: https://publicdata.au/api/v1/datasets/qld-traffic-census/rows?traffic_year=eq.2025&travel_direction=eq.BOTH%20DIRECTIONS&limit=5
- Aggregate: https://publicdata.au/api/v1/datasets/qld-traffic-census/aggregate?group=road_name&metric=max.aadt&traffic_year=eq.2025&travel_direction=eq.BOTH%20DIRECTIONS

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/<date>/` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets/<slug>/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.

## Questions

### How do I download Traffic census of state-controlled roads as a CSV file?

Open https://publicdata.au/d/qld-traffic-census/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/qld-traffic-census/v/2026-08-06/data.csv today. The same path serves Excel, JSON, GeoJSON, Parquet, SQLite, DuckDB, GeoPackage, GeoParquet, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same.

### Can I open Traffic census of state-controlled roads in Excel?

Yes. https://publicdata.au/d/qld-traffic-census/v/2026-08-06/data.xlsx is a workbook with the 74,823 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/qld-traffic-census/v/2026-08-06/data.csv.gz is the CSV at about a tenth of the size.

### What years does Traffic census of state-controlled roads cover?

The current version covers 2015 to 2025. Each release from Transport and Main Roads becomes a new dated version here, and earlier versions stay online.

### How often is Traffic census of state-controlled roads updated?

Transport and Main Roads releases it annually. This site checks the portal every week and adds a dated version when the file changes.

### Can I use Traffic census of state-controlled roads 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 Traffic census of state-controlled roads?

No. The publisher is Department of Transport and Main Roads, and its page is https://www.data.qld.gov.au/dataset/traffic-census-for-the-queensland-state-declared-road-network. This site republishes the publisher's file without changing its content. The original sits beside every version as source.xlsx with its SHA-256, so the two can be compared.

### How do I get only the rows for one traffic year?

Every version has one JSON file per value of traffic_year, 11 files in the current version, listed with row counts at https://publicdata.au/d/qld-traffic-census/v/2026-08-06/by/traffic_year/index.json. For example https://publicdata.au/d/qld-traffic-census/v/2026-08-06/by/traffic_year/2025.json holds the 6,984 rows where traffic_year is 2025. A GeoJSON file sits beside each one.

### What coordinate system does Traffic census of state-controlled roads use?

The publisher names no datum for the site coordinates. They are decimal degrees, read as WGS84 (EPSG:4326), the datum of the publisher's own KML of the same sites, and published as given. The GeoJSON file uses the same coordinates, which is what GeoJSON expects.

### What is in each row?

One traffic count site, year and direction of travel, with the estimated annual average daily traffic, the daily traffic and share in each vehicle class, and growth over one, five and ten years. Each row also gives the road, the segment of road the site represents, the speed limit, the coordinates and the TMR district, TMR region and council area.

### Why do three rows share one site and year?

Each site has a row for traffic with the gazetted direction of the road, a row against it and a row for both directions combined. Add only the rows for one direction, or use the BOTH DIRECTIONS row.

### Is every figure counted in the year it is for?

No. A coverage site is not counted every year, and the publisher then estimates the year's traffic from an earlier count. The year counted column gives when the count was made.

## 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.xlsx`.

## Improve this dataset

This page is built from [register/qld-traffic-census.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/qld-traffic-census.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
