A type of plane curve. It is also called the Cornu spiral. It can be expressed as follows, using a parameter s: For a car traveling at a constant speed on this curve, the rate of change in direction is constant, so the driver only needs to turn the steering wheel at a constant angular velocity. For this reason, this curve is often used as a curve on a highway.
