Finding a safe route for a person with a disability
A person with a disability, whether it is visually impaired or disability to walk, has no way of knowing in advance which route will be safer for him.
Possible solution: Add another layer to google maps so that it will offer the most accessible route based on existing information or based on information from users.
No sound crossing for the blind
A vehicle or obstacle that blocks the passage on the sidewalk
Narrow sidewalk or dangerous path
