Last calendar month Google reported on MIT's StreetScore. StreetScore rates the perceived security of locations inwards New York, Boston, Chicago as well as Detroit based on crowd-sourced reactions to Street View images. The ratings are based on MIT's citizen scientific discipline projection Place Pulse.
StreetScore gives a grade to each Street View place to charge per unit of measurement how rubber people perceive that place based on the overall responses to its Street View image. Over the concluding calendar month I've been thinking a piddling virtually how the StreetScore information could hold out used inwards a routing application to suggest routes based on perceived safety. It turns out that similar all my peachy ideas person has already beaten me to it.
UrbanGems has been running a similar citizen scientific discipline projection every bit MIT's Place Pulse. Urbangems shows users 2 Street View images side-by-side as well as and thus asks them to vote on which ane is to a greater extent than beautiful (or tranquillity or happy). UrbanGems is as well as thus able to rank how beautiful (or calm or happy) each place is perceived based on the combined votes of all the participants inwards the project.
UrbanGems has forthwith released a query paper, 'The Shortest Path to Happiness: Recommending Beautiful, Quiet, as well as Happy Routes inwards the City'. In the newspaper the researchers suggest a mapping service that automatically suggests routes that are perceived every bit to a greater extent than beautiful. The routing service would move the ranking scores derived from the UrbanGems projection to suggest routes that may add together a few extra walking minutes to a journeying if it is perceived to hold out to a greater extent than beautiful (or tranquillity or happy).
If yous desire to exercise your ain routing application based on perceived security yous could move the information from MIT's StreetScore project. MIT has released the information of the StreetScores for Boston as well as New York and it is available for download inwards 2 comma separated CSV files.
It is a fairly uncomplicated chore to exercise a ranking for each block department of a street past times combining all the StreetScores betwixt 2 intersections. Once yous accept rankings for each block department of all the streets inwards a metropolis yous could exercise an A* search algorithm to search for routes that are perceived every bit to a greater extent than safe.
