Duplicate Keywords - List #30 (Proposals for Permanent Merger and Auto-Conversion) (transportation keywords)

Here is the next installment of my lists of proposed keywords for permanent merger and auto-conversion. 

I am posting this for fellow contributors to review first and raise any objections or questions. I will wait at least seven days before changing this post to a "problem" post and asking IMDb staff to make the proposed changes.

The mergers and auto-conversions should be made in the direction of the arrows.
