Roads are intended to provide a specific network of pavement intended for vehicular transit. This will include the definition of the street names, and the role every type of road will be. There will be a number of different road types – all designed to meet a particular role. This is important to designate as if there were no rules in naming the streets, then things will be more chaotic. And since there are distinct definitions, all roads in the nation will have the same definition and qualifications as opposed to streets.
In reality, I would have rather included Solar Roadways in the code standards, but as much as I will wish to include that, it would seem to be vaporware. With that being said, it would not be able to be a standard part of code in the fictional country. However, the concept of Solar Roadways would have been an excellent idea indeed.
