Aggregated GPS data source

New data source for U.S. geographies: Aggregated GPS data. This allows you to analyze the most recent data months. To use this new data source, set the source parameter in your Metrics request to AGPS.

📘

The source parameter defaults to lbs_plus. You only need to specify the source parameter if you want to analyze the data months above; you do not need to edit your existing requests unless you want to use the new Aggregated GPS data source.

To check the latest data months available for the Aggregated GPS data source, use the Date Ranges endpoint.

The Aggregated GPS data source also allows you to analyze the following new metrics:

• free_flow_factor
• free_flow_speed
• speed_percentiles
• speed_count
• seg_travel_time_secs
• max_1hr_speed

For more information, see Available Metrics.
