### Solved - Vertical parabolic curve - PVI, PVC and PVT and Elevations at different stations along Curve

Hi,
Here is the example which shows you how to solve for the vertical transition curve elevation.

Problem: A 3% grade intersects a -2% grade at station 4+350m with an elevation of 190.5m. Given that a 250m symmetrical parabolic curve highway is utilized, determine: elevation in meters at station 4+240

elevation in meters at station 4+260

elevation in meters at station 4+280

elevation in meters at station 4+300

Solution: Please refer the images below.

thanks!
