The paper is here, but unfortunately this government funded research is not open access.

I guess an open question (at least for me) is whether, in an urban setting, it's better to install a dozen fast chargers, or hundreds of slower chargers – like two for all 100 street lamps in an area.
What's more useful? Particularly in areas where people do drive a bit (the school run, shopping, whatever) but don't drive that much (they use transit, no huge daily commutes).
For me (apartment, shared garage, hard to adapt) I guess a more easily available but slower charger that replenishes the few kms that I drive every other day during a night seems more useful than scheduling a couple hours on fast charger on the supermarket… just to get there and find it's unavailable.
But they only installed 30 chargers, so it'll be hard to draw conclusions.
