What does a variable lane mean?

[GarrettLynn]

Variable lane refers to a lane with multiple diagonal lines drawn on the inner side, somewhat resembling a lying-down 'non' character, which can change its direction indication at any time according to traffic flow. It is mainly designed for road sections where traffic is concentrated during peak hours but lanes are relatively few, or where there is a significant difference in traffic flow between morning and evening peak hours. When encountering such a lane, simply follow the direction indicated by the variable lane. Variable direction lanes are primarily set up at intersections, allowing flexible adjustment of traffic flow direction based on the characteristics of vehicle flow during different periods, thereby changing the driving direction of the lane to alleviate traffic pressure. They are particularly suitable for intersections that require time-based traffic management measures. The purpose of setting up such lanes is to address the vehicle flow direction at intersections with severe tidal traffic phenomena.
