I think the really cool potential for traffic jam abatement is when basically everyone uses on-line GPS routing (like Google maps), which can dynamically route vehicles based on the traffic density to approach a global minimum. There is actually research about this, like http://papers.ssrn.com/sol3/papers.cfm?abstract_id=577201 http://papers.ssrn.com/sol3/papers.cfm?abstract_id=577201
