What does the blue line on the navigation represent?
2 Answers
The blue line displayed on the navigation represents the driving route from the starting point to the destination. Below is relevant information: 1. Color variations indicate road conditions: Most navigation systems use color changes to represent real-time road conditions. Red indicates severe congestion, yellow represents slow traffic, and green means the road ahead is clear. 2. Two types of navigation systems: Navigation systems include mobile phone navigation and car navigation. Car navigation is equipped with GPS (Global Positioning System) functionality, allowing drivers to know their exact location anytime while driving.
I use navigation every day during my commute and have noticed that the blue line represents the currently planned driving route for me. Opening the map clearly shows it marking the entire path from the starting point to the destination. For example, yesterday when I took the elevated highway in the city, the blue line followed the main road and thickened before turns as a reminder. If there are forks in the route, it occasionally splits into blue and green lines, with blue always being the main recommended path. I've tried deliberately deviating from it, and the blue line recalculates in real-time—very smart. Moreover, in night mode, this line becomes even more prominent, preventing me from getting distracted by road signs. When traffic jams turn it red, I take detours in advance. Daily navigation relies entirely on this blue line for direction, saving me a lot of time finding my way.
