Divide a given road into equally divided kilometers and assign a class value for each record in it

I have a given road on QGIS map, and data is plotted along the road, I want to do the following:

1. Split the road into equally divided segment (each 1 km).

2. For each record in each segment, assign a class value to it.

For example, if my road is 10km, I want to divide it into 10 segements, each one is 1km. Then for each record in my dataset, i want to give a class name like : (A) to all records in the 1st km, (B) to all records exsist in the 2nd km, and so on. See the attached pic for reference.
