Basically, the right of way is a crossing right that is not yours. While the general public access is a global right that can be enjoyed by the public, a private right-of-way is limited to specific people (or teams). For those that can use it, a personal access is not personal. Instead, it links to itself to property or land with which these people belong. For example, the landowner that deserves to travel will just make use of the right to travel as long as he is the landowner. This passes to the brand-new proprietor once he buys the land.
