I think they need to figure out a way for the mapping utilities like RWGPS or Strava to integrate incident reporting. So if on a ride you encounter a problem, you can report it and it would appear as a small icon specific to the type of incident. If multiples happen in the same area, the icon would accrue a little number. I thought the driving app Waze does something like this.

Then overlay this with the already existing DOT data on traffic volume per road color code.

So when planning a route, you can see what you're getting into. Majority of fatal and serious bike accidents in towns sometimes occur in pretty concentrated areas.

So stuff like this:
-tire destroying debris in bike lane
-doorings near hit
-hits/near hits
-high/dangerous traffic
-dogs
-extreme poor road condition worse than expected
-close passes
