Last calendar month Google reported on MIT's StreetScore. StreetScore rates the perceived security of locations inward New York, Boston, Chicago together with 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 prophylactic 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 almost how the StreetScore information could locomote used inward a routing application to suggest routes based on perceived safety. It turns out that similar all my slap-up ideas somebody 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 ii Street View images side-by-side together with and thence asks them to vote on which i is to a greater extent than beautiful (or tranquillity or happy). UrbanGems is together with thence able to rank how beautiful (or calm or happy) each place is perceived based on the combined votes of all the participants inward the project.
UrbanGems has directly released a enquiry paper, 'The Shortest Path to Happiness: Recommending Beautiful, Quiet, together with Happy Routes inward 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 role 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 locomote to a greater extent than beautiful (or tranquillity or happy).
If y'all desire to practise your ain routing application based on perceived security y'all could role the information from MIT's StreetScore project. MIT has released the information of the StreetScores for Boston together with New York and it is available for download inward ii comma separated CSV files.
It is a fairly uncomplicated work to practise a ranking for each block department of a street past times combining all the StreetScores betwixt ii intersections. Once y'all convey rankings for each block department of all the streets inward a urban center y'all could practise an A* search algorithm to search for routes that are perceived every bit to a greater extent than safe.
