Streetlights seem to be either on, or off (if we forget about any warming up period).
It’s usually hard to make a case for lighting some streets more brightly than others.
It seems, however, that New York has now made available data which map where road accidents occur.
Today’s invention is to use this information to vary the light emitted from individual streetlights.
An area with a high incidence of traffic accidents would automatically get their lights set to brighter-than-normal. Other, less accident-prone streets would be less brightly illuminated.
This would result in an easing of accident blackspots, as well as a net reduction in the lighting costs for hard-pressed city administrators.
