Smooth type cross road in cities

Abstract

The invention discloses a smooth type cross road in cities. The smooth type cross road is characterized in that a left curved side lane is arranged on the outer side of a left curved lane on the ground of a straight high-level bridge, and the front end of the left curved side lane is connected with a left curved lane along the road; the entrance end and the exit end of a motor-vehicle left curved high-level bridge in the opposite directions of the arc shape and an arc opening of a bridge main body are respectively provided with an inner branch bridge section and an outer branch bridge section, and the tail ends of all branch bridge sections are respectively set as slope openings which are connected with the corresponding ground roads in sequence; an inner branch bridge section slope opening in the entrance direction of the left curved high-level bridge is connected with the left curved lane in the cross road section, and an outer branch bridge section slope opening is connected with an arc of a left curved lane in the adjacent direction in the cross road section; and a slope opening of the inner branch bridge section in the exit direction of the left curved high-level bridge is connected with the left curved side lane in the cross road section and passes through under the entrance branch bridge section of the opposite left curved bridge, and an outer branch bridge section slope opening is connected with an arc of the left curved lane in the adjacent direction in the cross road section. According to the smooth type cross road in the cities, the structure is simple and the passing route is intuitive and clear.

Description

technical field [0001] The invention relates to a road structure and a traffic route arrangement for releasing the control of traffic lights for smooth and unimpeded traffic in urban traffic, in particular to an urban smooth cross road structure. Background technique [0002] Cross road traffic in urban areas of various countries in the world generally uses traffic light signals to guide vehicles and pedestrians. With the development of society, the improvement of people's living standards, and the popularization of private cars have caused a surge in numbers. However, due to infrastructure construction such as traffic roads Failure to keep pace with the times has led to traffic congestion, especially at intersections, and congestion is a common occurrence. Traffic accidents caused by cars and people competing for lanes, and cars and cars grabbing lanes occur frequently. For this reason, people have managed to build viaducts, multi-layer overpasses and other measures at the ...

Take a crowded intersection in a city as an example. In this intersection: the two-way roads on the ground in all directions of the original road are arranged from the center to the outside for motor vehicles, with left curves, straight lanes, and right curves, non-motorized lanes, and sidewalks. , passing vehicles and pedestrians in all directions are controlled by traffic lights; although the traffic light control has commanded the traffic order, due to the centralized scheduling of traffic lights, the diversion of each road is not smooth, and the time for vehicles to pass is too long, resulting in a lot of valuable traffic. Time flies by waiting for cars, so high-speed cars and their high-speed development and backward facilities of urban roads form a huge modern contrast! Moreover, the slowdown or frequent starting of vehicles due to waiting for vehicles not only wastes fuel resources, but also seriously pollutes the air quality in the area due to exhaust emissions.
