A method of a sidewalk mapping server comprising:

• determining a start location and an end location of a sidewalk in a neighborhood area;
• determining a transition characteristic of the sidewalk transitioning into a street, wherein the transition characteristic is at least one of a grade-down transition, a grade-up transition, and a gradual transition in at least one of the start location and the end location of the sidewalk in the neighborhood area;
• and
• generating a sidewalk map of a neighborhood based on a slope angle of the sidewalk transitioning into the street and a determination of the transition characteristic of the sidewalk transitioning into the street.
