Transportational is the adjectival form of transportation, a real word used rarely enough to be available. It describes anything relating to the movement of people and goods.
On the .org the policy and advocacy readings come forward, and that’s a substantial sector. Transit advocacy, road safety organisations, active travel campaigns, and the research institutes working on mobility policy are all nonprofits, and there are a great many of them in every country.
The adjective form has an advantage over the noun. Transportation names a sector; transportational describes a quality, which lets one name cover research, advocacy, data, and design work without committing to any single one. For an organisation with several programmes, that flexibility is useful.
Sixteen letters, entirely phonetic, one spelling, no hyphen. It’s long, and what you get for it is a genuine English word with no competing owner and a clean trademark path.
