• AADT analyses now use the oz_sets to define a zone set; the az_sets parameter has been removed.
• AADT analyses must now set travel_mode_type to All_Vehicles_AGPS
• Data months are now available in the Network Performance analysis type for Canadian accounts.

With the Network Performance analysis type, you can now select to get spot metrics or segment metrics. For more information, see Setting up Nework Performance analyses.

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.

Data months for Canada

New data months are available for Canadian geographies for January 2019 through April 2022. For details on metrics you can get, see Available Metrics.

• You can now run Network Performance and Network Origin-Destination analyses using the StreetLight InSight® API.
  • To set up these analysis types, you must specify zones using the osm_ids parameter in Create a zone set, and select the All_Vehicles_AGPS travel mode for your analysis.
  • For more information, see Setting up Nework Performance analyses and Setting up Nework Origin-Destination analyses.
• You can use OpenStreetMap (OSM) segment IDs to specify line segment zones in the Create a zone set endpoint with the new osm_ids parameter. The new Search OSM IDs endpoint lets you get OSM IDs for a geometry that you specify. For more information, see Defining Zones > Specifying Zones with OSM IDs.

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.

• The new Edit an analysis endpoint lets you edit the name and description of an existing analysis.
• The new Cancel an analysis endpoint lets you cancel an analysis that is running or queued to run.
• The Delete an analysis endpoint lets you delete an existing analysis.

• You can analyze month over month or year over year time trends in one API call by setting multiple date_range parameters when requesting metrics and comparing data between data periods. For more information, see Analyzing Time Trends
• The nearest geometry type allows you to query the segments nearest to a supplied point.

• Vehicle data for U.S. geographies for months in 2019 is now available from the metrics endpoint. To check available data months, use the Check available data periods endpoint.

• The new Download shapefile endpoints let you download a shapefile of the zones used in an analysis you have run.
• The new Get zones endpoint lets you query information from zones or zone sets that have been created from the API or StreetLight InSight® web app.
• Each API key can have up to 250 analyses running and waiting to run at a time.
• The new in_queue parameter in the Search analyses endpoint lets you search analyses that are currently in the analyses queue.

The geom_mode property is available for endpoints where you define a geography. You can set geom_mode to determine whether your query includes only segments within your defined area, or segments within and intersecting with your defined area.
