}Key features and capabilities
What the Google Maps Traffic Alerts API supports out of the box.
- Get all live traffic incidents in any geographic area worldwide, sourced from Google Maps, with a single request.
- Every incident is returned with its type - accident, construction, road closure, or other incident - so you can filter and prioritize on your side.
- Each incident carries precise latitude and longitude coordinates, ready to plot directly onto a map or feed into routing logic.
- Target any area with a simple bounding box (bottom-left and top-right coordinates) plus an optional zoom level for incident granularity.
- Live traffic conditions on every call - the response reflects the current state of the road, not a stale snapshot.

What is the Google Maps Traffic Alerts API?
The Google Maps Traffic Alerts API returns live traffic incidents for any geographic area, sourced from Google Maps. For a given map area, you get every reported incident - accidents, construction zones, road closures, and other slowdowns - each with its incident type and precise latitude/longitude coordinates, so you can plot and monitor what is happening on the road right now.
How do I subscribe to the Google Maps Traffic Alerts API?
Click "Try for Free" above or subscribe on the developer portal. The free tier includes 50 requests with no credit card required.
What types of traffic incidents does the API return?
Each incident is labelled with a type: accident, construction, road closure, or a general incident covering other slowdowns and hazards. Every incident also comes with precise coordinates, so you know exactly where on the map it is located.
How do I query traffic alerts for a specific area?
You define the area with a bounding box - a bottom-left and a top-right latitude/longitude pair - plus an optional zoom level that controls how granular the returned incidents are. The API returns all traffic incidents inside that box, along with a count, so you can request exactly the area you care about.
How fresh is the traffic data?
Every call reflects the current state of the road as reported on Google Maps. The data is live traffic conditions, not a snapshot from minutes or hours ago, which makes it suitable for real-time monitoring, alerting, and routing decisions.
Can I use the API to cover a large region?
Yes. Query each area with its own bounding box and merge the results on your side to build coverage of a city, a metro area, or a whole region. Adjust the zoom level per area to balance incident granularity against the size of the box you are querying.
What are common use cases for this API?
Traffic monitoring dashboards, fleet and logistics route optimization, smart city and urban mobility platforms, incident detection and alerting systems, navigation and ETA features, and any application where knowing the traffic incidents in the area right now changes the outcome.
