It contains concepts, guidelines, and computational procedures for computing the capacity and quality of service of various highway facilities, including freeways, highways, arterial roads, roundabouts, signalized and unsignalized intersections, interchanges, rural highways, and the effects of mass transit, pedestrians, and bicycles on the ...
Because of this, some planners recommend increasing population density in towns, narrowing streets, managing car use in some areas, providing sidewalks and safe pedestrian and bicycle facilities, and making the scenery interesting for pedestrians.
