Yes, it does export the model of the city, but it doesn't export the roads and fields... Or at least I am not able to find them importing the obj in Blender.
Ah, right. Now I remember that I don't export them to OBJ because they are flat :) I will probably add them to exported data later. For now you can try to import them from JSON. Please note, that even in JSON there is information about "large" roads only - no alleys.
