Help with Traffic System Unity

Hello, i have a problem with traffic system in my unity game, i've a game with AI Traffic system. The AI Vehicles and characters follow their path but i need to create new one, in order to do that i need to write a new TextAssets File with serialized data {Position (x,y,z)} as the AI Vehicles can follow the path. can you do that?
Note: All scripts for serialization and deserialization are already integrated in the project.
