Depends on the project and shift timings also.

If you are asked to come in a shift other than 0830 - 1830 then you can ask for a cab, respective of which project you work for.

As far as I know, free transportation is part of employee benefit and it should also be mentioned in your CTC agreement.

Cab facility is depend upon project
