What does 'ramp' mean?

[SanGage]

Ramp, also known as an approach, refers to the section of road that connects the upper and lower roads of an overpass or elevated road, as well as the section that connects the highway with adjacent auxiliary roads. Below are definitions of various types of ramps: 1. Entrance and exit ramps: These are auxiliary connecting sections for entering and exiting the main road, also known as approaches. In engineering terms, they typically refer to a short section that provides vehicles with access to the main road and adjacent auxiliary roads, or other main roads via bridges/slopes/connecting roads, as well as collector-distributor roads. They are a major component of road interchange construction. 2. Up and down ramps: These are auxiliary connecting slopes for entering and exiting elevated roads, moving upwards or downwards, usually referred to as 'interchange ramps.' Note: The above two types (items 1 and 2) often incorporate the design of collector-distributor roads. 3. Direct ramp: Places the left-turn lane on the left side. 4. Indirect ramp: Places the left-turn lane on the right side, using a loop to connect with other highways. 5. Semi-direct ramp: Similar to an indirect ramp but does not use a loop; instead, it uses a longer, more undulating elevated road as the connecting ramp.
