What does the red road surface on the highway indicate?
1 Answers
Highway navigation red sections indicate road congestion. Roads displayed with green lines generally indicate that the current traffic conditions are smooth and unobstructed. Generally, navigation maps use colors to differentiate traffic flow and road condition information for sections. Yellow sections indicate slow-moving traffic conditions, red sections represent severe congestion, yellow sections denote slow-moving traffic, green indicates smooth and unobstructed roads ahead, and gray sections indicate that the road is under construction, so please detour in time. Car navigation systems feature GPS global satellite positioning functionality, allowing drivers to know their exact location anytime while driving. Car navigation systems include automatic voice navigation, optimal path search, and other functions. They can provide driving navigation, route recommendations, information queries, AV/TV playback, and more. The field of navigation includes four general categories: land navigation, marine navigation, aeronautical navigation, and space navigation. This is also the art term used by navigators to perform navigation tasks with professional knowledge. All navigation techniques involve locating the navigator's position in comparison to known positions or patterns.
