Highway Radar

Application alerting on speed traps

Reference and FAQ

How should I configure police alerts server?

We don't provide a service for aggregating real-time crowd-sourced police alerts; instead, we give an application using existing services for getting data. This means that to use police alerts feature in this application, you need to input an address of a server providing the police location.

The server address can be entered in the settings menu under "Server hostname" field.

NOTE: Despite entering waze.com as a server address will show real-time police alerts directly from Waze, it violates Waze ToS and might be illegal in your country.

How should I configure secondary aircraft server?

Aircraft alerts receive real-time aircraft positions via ADSB-exchange service. Highway radar allows adding a secondary server for aircraft positions. The data from the secondary server are combined with the data from ADSB-exchange to finally get more accurate and complete locations of the aircraft in the sky.

The server address can be entered in the settings menu under "Secondary server hostname" field. Specifying the secondary server isn't required for the aircraft alerts to work since if this field is empty, only ADSB-exchange data are used.

NOTE: Despite entering flightradar24.com as a server address will pick aircraft positions directly from Flightradar24, it violates Flighradar24 ToS and might be illegal in your country.

Can I mute/unmute a single alert?

Yes, just tap on this alert to mute or unmute it.

What is the risk level and how predictions work?

Highway Radar uses an array of historical data for estimating a chance of meeting police at this location. The estimation is solely based on past user reports. This feature is experimental now and might not always be 100% precise.

The estimation is a number from 1 to 10 and a chance of having a police report here and now. For example if it is 2:17 pm now, and the app shows "40-70% in 3mi ±1h" then it means that based on historical data the chance of having at least one police report during the day in a circle around current location with a radius of 3 miles within 1 pm to 4 pm time frame is laying between 40% and 70%.

The application alerts on police that is not on my way / on another street.

Highway Radar doesn't use a map inside yet so it can't know if you and reported police are on the same street or not. Despite there is a map view, Highway Radar treats the map being shown only as a picture and doesn't understand on which street you're driving. This shouldn't be an issue on highways, and it is still important to know there is police operating in the area.

I see an aircraft in the sky but the application is silent.

Highway Radar uses various of techniques to filter out all non-patroling aircraft. For example, the application will check the aircraft model (you'll very unlikely see patrolling A380), check aircraft owner, speed, altitude, and many other parameters. This filtering works really well and filters out >99% of all uninterested aircraft.

You can enable the "Show safe aircraft" option in the settings menu to have all visible aircraft displayed on the screen (has no effect in the map view though). You still won't get any alerts on safe planes (e.g., on passenger aircraft) but will see them on the screen among inactive (gray) alerts.
