How safe does this street "look" to a Human?

NOT

How safe is this street?

Very important distinction - I would suggest changing the name of the project to "PerceivedStreetScore".

What is now needed is actually part 2 of this project - one that pull records from City/County/Federal crime stats, overlays them with a Map and then actually produces a "ActualCrimeScore" for each of these highlighted streets.

Then compare the two scores and write an (excellent) definitive paper titled "Factors that influence Human perceptions of safety - Lessons for City Planners"
