November 28, 2023 - StreetLight Advanced Traffic Counts API

New data source for U.S. geographies: Connected Vehicle Data (CVD). This allows you to analyze 2022 data months, as well as attributes that describe vehicles in the sample. To use this new data source, set the new source parameter in your Metrics request to cvd_plus.


The new source parameter defaults to lbs_plus, which was previously the only data source. You only need to specify the source parameter if you want to analyze the data months or metrics above; you do not need to edit your existing requests unless you want to use the new CVD data source.

To check the latest data months available for the CVD data source, see Date Ranges.

You can query new fleet attribute metrics when using the CVD data source. For more information, see Available Metrics: Vehicle Attributes.
