In essence what you are trying to say with this:
"Due to [the simplicity] and [intuitivity of] Road Map, everyone seems to love it."
"Due to [the quality or condition of being plain or natural] and [the quality or condition of being easy to use and understand] Road Map, everyone seems to love it."
The word simplicity is a noun, but there is no equivalent word that is derived from intuition (intuitivity) to go with it in that context. The only matching derivative of intuition that will be found in a dictionary, is also a noun, and is widely accepted and understood is intuitiveness.
Your options are to either use the accepted word (intuitiveness) or use intuitivity, but place quote marks around it:
"Due to the simplicity and "intuitivity" of Road Map, everyone seems to love it."
