High-Level Context Diagram

Personas

end users

Our end users include 3 main groups in NYC:

• People with visual impairments(low vision or blind) who rely on signal poles with audio when crossing the street
• People with mobility issues in wheelchairs(injured, disabled, or elderly) who use curb cuts/ramps on the street
• Friends, family, or care-takers who have to frequently travel with the disabled individuals that need assistance

End users can input the destination for their commute and locate nearby signal poles that support audio walk signals, accessible ramps for their wheelchairs, or raised sidewalks that they should avoid. When logged in, users can add their frequently searched destinations to a list of favorites, as well as report any temporarily inaccessible streets for other users to see.

admin

Admin is another user group that helps moderate the database. They can view new reports and help flag or resolve ongoing issues displayed on the map to make sure information is constantly updated for our end users to see. Our admin will have their own login credentials. (note: admin features are MLP and might not be implemented.)
