As per IRC:73 1980, clause no 9.1.8, a ratio of 1.5:1 should be considered as a limiting value.

Yes, you are correct, thanks@Harsh verma.

Right @Harsh Verma.
If the sharper curve has a very less radius than the ratio will be >1.5, thus a vehicle moving from a flatter curve to a much sharper curve will cause discomfort to the passengers.

To ensure a safe and smooth transition from curve to curve the radius of the flatter curve should not be disproportional to the radius of the sharper curve.
A ratio of 2:1 or preferably 1.5:1 should be adopted.
