What does P.C. stand for in roadway terminology?

In roadway terminology, P.C. stands for Point on Curve. This is an important concept in roadway design and engineering, as it refers to a specific point where a curve begins. Understanding the point on curve is crucial for determining how vehicles will navigate through curved sections of the road, influencing factors like sight distance, alignment, and safety.

This terminology is part of the geometric design of roadways, where precise measurements and definitions are necessary for creating efficient and safe transportation systems. By identifying the point on curve, engineers can accurately calculate the radii of curves, transitions, and other critical elements that affect vehicle dynamics and roadway performance.
