What does ramp mean?

Ramp usually refers to a short auxiliary lane that provides vehicles with access to and from main lines (such as highways, elevated roads, bridges, and vehicular tunnels), or connecting roads like overpasses, ramps, approach roads, and collector-distributor roads of other main lines. It is a key transportation infrastructure that constitutes road interchanges and an indispensable component of grade-separated interchanges, serving intersecting roads for entry and exit. Whether the ramp is designed reasonably directly affects the performance of the grade-separated interchange, the safety and smoothness of traffic, operational economy, and engineering investment. Therefore, it should be arranged and designed with appropriate alignment based on key design principles.
I remember when I was first learning to drive, I often heard people talk about ramps but didn’t understand what they meant. Later, after driving more on highways, I realized they’re those sloped or curved small roads specifically designed to connect regular roads to the entrances and exits of highways. Like the first time I got on the highway, I saw a sign that said 'Entrance' and drove up the slope—that was the ramp. The key is to accelerate to the speed of the main road while on the ramp to avoid being rear-ended by vehicles behind. During peak hours, it’s especially easy to get stuck on the ramp, with cars lining up and unable to merge because too many people are rushing to cut in. Safety is crucial—engineers design ramps with appropriate curves to reduce risks. I often remind my friends to check their rearview mirrors more often on unfamiliar ramps and stay focused to avoid missing signals or taking the wrong lane. Over time, I’ve developed a habit: when passing through a ramp, I slow down mentally, avoid competing for space with others, and prioritize the safety of my vehicle and smooth traffic flow around me.
