What does the red color on the navigation mean?

Navigation uses red to indicate traffic flow conditions on the road. Red represents congestion, while green indicates smooth and unobstructed traffic on the current route. The red color serves as a reminder for drivers to consider alternative routes. Car navigation systems utilize the GPS (Global Positioning System), typically featuring automatic voice navigation and route search functions to ensure efficient and stress-free driving. A car navigation system mainly consists of two parts: a GPS receiver and display device installed in the vehicle, and a computer control center. The navigation system also supports one-touch Bluetooth hands-free functionality, with a built-in Bluetooth hands-free device enabling drivers to make calls with a single button press while driving.
Using navigation while driving is quite common nowadays, and I’ve noticed that the red areas usually indicate severe traffic congestion. For example, when I commute in the city, a red section on the screen means the traffic ahead is almost at a standstill, likely due to rush hour or an accident. The navigation system uses different shades of red to show the severity of congestion—from light red to dark red, indicating slow-moving traffic to a complete halt. This relies on real-time traffic data integration, such as speed reports from other vehicles. I usually tap to reroute when I see a red zone to avoid traffic jams, saving a lot of time. It’s also helpful for weekend trips to predict and avoid long delays on highways. Overall, the experience is good and improves travel efficiency, though occasionally the system data may lag, so it’s advisable to refresh for the latest updates.
