One example is timed traffic lights, which are inefficient. Traffic lights should be modified to anticipate traffic (e.g. through image recognition), and direct traffic with greater intelligence. Over time, standards could be developed for communications between cars and traffic lights. This could improve safety by warning cars when they are not slowing for a light that is turning red. It could reduce both traffic and pollution.
The IParty should use a deliberative process to find the most promising candidate technologies, and vote on the best ones.
