I'm not sure if it has been looked into yet, but once EVs are abundant it would make sense to look into ways of reducing pollution from road wear. Right now it's not worth it as much, since pollution from the cars themselves dominate. But once road wear is the dominant source it'll make sense to look into it.

Automated cleaning trucks which sweep the road for dust every day maybe? New materials for roads and tyres?

New materials might be tricky. Roads are very abundant, and in some places of the world they're a convenient way of disposing of the leftovers of incinerated waste.
