What does the blue section in navigation mean?
2 Answers
Navigation blue sections indicate areas without real-time traffic information. Navigation maps use four color codes for traffic conditions: 1. Green means the road is currently clear; 2. Yellow indicates slow-moving traffic; 3. Red signifies severe congestion; 4. Gray with construction markers shows the road is under maintenance, suggesting detours. Navigation systems utilize GPS satellite positioning to keep drivers informed of their exact location at all times. Features like voice-guided navigation and optimal route calculation help drivers find shortcuts for unimpeded travel, while integrated office and entertainment functions ensure comfortable and efficient journeys.
I've been driving for ten years, and I can instantly understand the meaning of the blue sections on the navigation—traffic is exceptionally smooth, with cars flowing freely like a river, completely unobstructed. Every day during my commute, I rely on the navigation colors to judge: blue represents the best condition, with fast flow and no delays; green is second best, with minor traffic obstacles; yellow is a bit slower, possibly indicating congestion; and red is disaster mode, completely jam-packed. These colors are updated based on real-time GPS data, with the navigation system dividing the road into segments and analyzing vehicle speeds to provide alerts. For example, in Google Maps or Baidu, blue consistently signifies a blessing during rush hour. Once, I was rushing to catch a flight and took a highway with many blue sections, speeding all the way and boarding the plane on time. The color-coding design of navigation is intended for safe driving, avoiding the risks of sudden braking in heavy traffic. Blue is the optimal choice, saving fuel, time, and peace of mind.
