Zonal

I like zonal constructed languages.

Interslavic is an example of a zonal auxiliary language.

Each commission has representatives at the zonal, provincial and district levels.

Decisions made at the DfT inevitably reflect a London-centric experience, with a comparison being made with the closure of ticket offices throughout the London Underground network. This is not judged to have been detrimental, but there is a simple zonal fares system that is hardly comparable with the range of ticket types used on the national rail network.
