Traffic (TsFile)

Apache TsFile version of the traffic long-term-forecasting subset of thuml/Time-Series-Library.

Overview

Hourly road-occupancy rates from 862 sensors on San Francisco Bay Area freeways.

• Rows: 17,544 time steps.
• Channels: 862 numeric variables.
• A single multivariate series; no TAG/device dimension.

Schema (TsFile structure)

• Time (INT64, milliseconds) — parsed from the source date column.
• FIELD (862 columns, FLOAT) — the measured channels. Channel names are made schema-safe (e.g. %→pct, spaces→_, leading digits prefixed c_).

The source date string is dropped (losslessly encoded into Time). No rows or numeric columns are dropped.

Usage

Read the .tsfile files with the Apache TsFile Java or Python SDK.
