Suggestion to include a notification of road works. Due to the reduced speed limits and traffic congestion this would be great to avoid.
You can report construction as a road hazard from the phone. Is there something more that you are suggesting?
Probably what has been asked for many times, the ability to report construction activities with reports that will affect routing and most of all not fade in 30 min or less. Something short of disconnecting the road and hoping map updates cycle frequently enough to semi-match the closure and re-opening dates.
