Tech Tips: How does Google Maps know there is a police presence ahead? Learn about the technology behind it..

Nowadays, navigation apps like Google Maps and Waze display various details such as traffic, road closures, speed cameras, ongoing roadwork, waterlogging, low visibility, and police presence. But how exactly does Google Maps know if the police are present on a road or if an incident has occurred there? The answer lies primarily with the app's users.

**Real-time information through crowdsourcing**
The core data for police alerts on Google Maps comes directly from the users—the drivers themselves. When a driver spots a police presence along their route, they can report it using the 'Report' option within the app while navigating. This alert then appears on the screens of other drivers passing through the same road.
Other users traveling along the route can also confirm the report. It is this crowdsourcing technique that keeps the real-time data on the maps updated.

**Utilizing data from the Waze app**
Google Maps doesn't just receive real-time alerts from its own user base; it also incorporates reports from Waze, another navigation app owned by Google. Google Maps can identify information that has been reported by Waze users.
Waze rewards users with points for submitting traffic and road reports, which encourages higher user activity on the platform. Accessing Waze's data provides Google Maps with more comprehensive and accurate information regarding road conditions.

Google has long relied on Machine Learning (ML) and AI to accurately estimate live traffic. Additionally, data is collected from all smartphones on the road that have navigation enabled.
However, direct user reports remain the most crucial factor for precise information like speed camera locations and police alerts.

**How ​​can you send police alerts on Google Maps?**

**Start Navigation:** Keep Google Maps in navigation mode on your smartphone, Android Auto, or Apple CarPlay. Tap on 'Report': Click the report (+) icon visible on the screen.
Select Police: Choose 'Police' (or another incident type) from the given options.
Submit Report: Once your report is submitted, a small police icon will appear at your location.
