Real-time slowdowns: how Triq spots traffic jams

Road safety Published on October 23, 2026

By TIAKI Sofien, publisher of Triq

Triq spots unusual slowdowns using anonymous speed samples sent by drivers who agree to share them. You see a banner, hear an announcement, the section is coloured on the map and a detour is suggested. Sharing is optional and off by default.

A road that suddenly slows down isn't always a visible accident. Triq tries to tell you before you get stuck in it. This feature arrived with version 0.11.0.

What you see and hear

When an unusual slowdown builds up on your route:

• a banner lets you know;
• the voice warns you;
• the affected section is coloured on the map;
• Triq suggests a detour.

It's up to you whether to take it.

Where does the information come from?

From drivers like you, who chose to help. Their phone sends small anonymous speed samples. The server only draws a conclusion when several batches agree: a single phone isn't enough to trigger an alert.

Sharing is optional

Speed sample sharing is off by default. Triq offers it to you only once, with an invitation. You can accept, decline, and change your mind in Settings with the "Help spot slowdowns" option.

By sharing, you help other drivers get warned in time.

What is sent

According to Triq's privacy policy:

• one sample per section of about 300 m: rounded area, direction, average speed, limit, time rounded to 5 minutes;
• never near your home or your work, nor at the start or end of a trip;
• sent in batches, then stored without a device identifier;
• deleted after 2 hours;
• no trip is recorded.

For everything else Triq keeps, read No account, your data stays with you.

A complement to reports

Slowdowns add to the alerts on your route, which rely on what drivers report by hand. Together, the two give a more complete picture of the road ahead.

An honest limit

A slowdown alert tells you where traffic is getting heavier, not why. It's up to you to judge on the spot. Triq only sees what drivers share. On a quiet road, it may detect nothing. Don't rely on the app instead of your own eyes.

In practice, picture a section that gets jammed at the end of the day. The phones that agreed to share report an average speed much lower than usual. Once several batches say the same thing, Triq warns you and suggests a way around the section.
