StreetLight data processes anonymized location records from various sources such as smart phones, navigation devices, and trucks. Additional context is added to this data by layering information from other sources such as parcel data and the roadway network. This data is then analyzed and aggregated into normalized travel patterns. Users can access this data via the StreetLight InSight platform.

StreetLight data primarily helps in analyzing origin-destination, annual average daily traffic (AADT) counts, segments, trip lengths, and route choice. StreetLight AADT counts are typically only used if no other data source is available. It is recommended that any traffic counts collected using the StreetLight platform be validated with permanent count stations or ADT where available. If there are no permanent count locations available, refer to temporary count locations or historical counts. It is important to note major differences between StreetLight counts and those collected from historical data, STARS II, or other resources.
