Abstract

A traffic-light-free overpass at intersections has roads arranged as follows: arranging from west to east a straight lane for ground-level motor vehicles, a straight lane for ground-level non-motor vehicles and pedestrians, a left-turn lane for ground-level motor vehicles, a right-turn lane for elevated motor vehicles; arranging from east to west a straight lane for elevated motor vehicles, a straight lane for elevated non-motor vehicles and pedestrians, a left-turn lane for elevated motor vehicles, a right-turn lane for ground-level motor vehicles; arranging from south to north a straight lane for underground motor vehicles, a straight lane for underground non-motor vehicles and pedestrians, a right-turn lane for elevated motor vehicles, a left-turn lane for elevated motor vehicles, a section of straight lane for elevated motor vehicles, a left-U-turn lane for underground motor vehicles; arranging from north to south a straight lane for underground motor vehicles, a straight lane for underground non-motor vehicles and pedestrians, a left-turn lane for ground-level motor vehicles, a right-turn lane for ground-level motor vehicles, and a left-U-turn lane for underground motor vehicles. The traffic-light-free overpass at intersections of this functional invention is built on the established roads rather than the new lands, which saves the capital investment, and has a complete function, where this overpass has exclusive lanes in each direction without crossings. The scale of the overpass is 5 times less than those in the market, which is beneficial to the rational use of the metropolitan tracks and traffic resources.
