What does acceleration lane mean?

[Orlando]

Acceleration lane refers to the lane used for vehicles to accelerate before merging into the high-speed traffic flow. Below is relevant knowledge about traffic roads: Basis for road length setting: The merging area of a highway includes ramps, acceleration lanes, and the associated main road section. The traffic capacity of a highway merging area differs from that of regular road sections. Both the main road traffic volume and ramp traffic volume significantly impact the operational characteristics of the merging area. Basis for determining traffic road capacity: Highway capacity refers to the ability of a road to handle traffic flow. Through capacity analysis, traffic flow operation parameters and service level indicators can be estimated and evaluated, allowing for the proposal of improvement plans or measures to address issues on highways.
