Trafi

Could you clarify what you mean by "trafi"? The term can refer to multiple, distinct topics (for example, a transit-related app or company often stylized as TRAFI, a word related to traffic in several languages, or a different subject altogether). If you specify the intended referent or region, I can write a concise, neutral wiki-style article under 300 words. If you want, I can also produce a disambiguation-style entry covering the main possible meanings.
