Abstract
I intend to account for that the roads in community area are classified into five categories. (1) roads for pedestrians; main routes for pedestrions. (2) roads for vehicles; not concerned with community; main vehicular routes and not concered with pedestrians and playing children They are not Community Roads. (3) semi-private roads; is no through traffic and the place for playing children, concerned with the only dwellers who face the roads. (4) pedestrian roads with vehicle access; there are conflicts between pedestrians and vehicles, and in general they are classified into collector roads. (5) vehicular roads with pedestrian; heavey trafficis on them, which are unpreferable for pedestrians, dwellers and playing children. In general they are classified into structural roade in town.
