What does the blue section in navigation mean?
2 Answers
Navigation's blue sections indicate areas without real-time traffic information. Below are relevant introductions about navigation: 1. Introduction: Navigation is a research field focusing on monitoring and controlling the movement of processes or vehicles from one place to another. All navigation technologies involve locating the navigator's position by comparing it with known locations or patterns. In a broader sense, navigation can refer to any skill or study involving determining position and direction. In this sense, navigation includes orienteering and pedestrian navigation. 2. Categories: The field of navigation includes four general categories: land navigation, marine navigation, aeronautical navigation, and space navigation. 3. Color meanings: Blue sections on navigation represent areas without real-time traffic information, red indicates severe congestion, yellow shows congestion, and green means smooth traffic flow.
I've been driving for over a decade and often rely on in-car navigation or mobile maps like AutoNavi or Baidu Maps to plan my routes. The blue sections on the navigation typically indicate smooth, unimpeded traffic conditions, meaning the road is currently free of congestion, allowing vehicles to move smoothly. In contrast, red represents severe traffic jams, while yellow indicates slow-moving traffic—blue is the best option and is often recommended by the system as the optimal path. However, it's important to note that color meanings may vary slightly depending on the app. For example, on Google Maps, blue usually represents bodies of water rather than traffic conditions, whereas in apps like Waze or professional car navigation systems, blue is a common signal for clear passage. I believe new drivers should develop the habit of checking these colors and promptly switching to blue routes to save fuel and time, especially during peak hours when avoiding red and yellow zones is crucial. It's also wise to regularly update maps to prevent system errors from leading to misjudgments—after all, navigation is just an aid, and drivers should still pay attention to real-time road signs and signals. In short, blue lines signify efficient travel, and utilizing them can make trips much easier.
