You can now query analyses tags with the new tags query endpoint. You can also query device and sample trip counts for an analysis. For more information, see List available tags.

You can now set the travel_mode_type parameter to All_Vehicles_By_Weight when running an AADT analysis.

You no longer need to request metrics for truck weight segments with the vehicle_weight parameter, as truck metrics are now automatically segmented by medium-duty and heavy-duty weight classes.

Welcome to the developer hub and documentation for StreetLight Data!

Analyses with Traveler Attributes and a date period starting in January 2019 or later now require that you request metrics for individual Traveler Attributes when you query the analysis status. Traveler Attributes after January 2019 are based on 2020 US Census data and 2019 ACS.
