Method for automobile crossless passing at same level of city road and its construction

Abstract

The invention relates to a method for autombile crossless passing at same level of city road, setting a turn disc on two sides of main road cross or branch cross the main road car flow cross straighly, the car need to turn left will turn on the left after reaching the steering wheel, then turn on the right when backing to the cross; the branch road car need to turn left or cross the main road first go with the main road car to the same direction to the steering wheel, then turn on the left, get into the main road car flow to go ahead or turn on the right to the cross. The turn disc is comprised of carrying backbone and two panels, brake bar and seesaw or roller, the '+'-shapled beam of carrying backbone has its center link to the seat, with its four points linking to idler wheel or ball by a circular track, the two panels are arranged cornerwise, with the radial and circular arc bevel edge being dome. The invention has solved the problem of turning on the left, making the cross smoothy.

Description

technical field [0001] The invention relates to the field of urban traffic, in particular to a method and facilities for urban road network vehicle flow plane non-crossing intercommunication. Background technique [0002] The increasingly congested traffic has become more and more difficult to adapt to urban development: intersections with mixed flow of people and vehicles, more traffic lights, and less effective passing time (the time spent going straight and turning left is 1 / 4 running, 3 / 4 stopping, etc.), The frequency of vehicle braking (stopping, starting) is high and the speed is slow (the US road capacity manual refers to the unstable traffic flow on urban arterial roads with a speed of less than 22km / h as congested traffic flow, while the average operating speed in major cities in my country is only 12- 18km / h), increased fuel consumption and exhaust emissions; it is inconvenient for people to get up and down on overpasses and underground passages; people and vehicles...

Problems solved by technology

[0002] The increasingly congested traffic has become more and more difficult to adapt to urban development: intersections with mixed flow of people and vehicles, more traffic lights, and less effective passing time (the time spent going straight and turning left is 1 / 4 running, 3 / 4 stopping, etc.), The frequency of vehicle braking (stopping, starting) is high and the speed is slow (the US road capacity manual refers to the unstable traffic flow on urban arterial roads with a speed of less than 22km / h as congested traffic flow, while the average operating speed in major cities in my country is only 12- 18km / h), increased fuel consumption and exhaust emissions; it is inconvenient for people to get up and down on overpasses and underground passages; people and vehicles on the "zebra crossing" compete for the road, and traffic accidents occur frequently; from the point of view of the entire city node, parking and passing time are equivalent, In addition, some "clearing losses" such as yellow lights that cannot be used will waste more than half of the passing time every day; red lights on pedestrian crossings will cause 5-5% of the road surface to be vacant every minute; overpasses are expensive, occupy a large area, and only The location of the block has been shifted

[0003] The continuous construction, repair, and expansion of overpasses, ring roads, and road widths in Beijing have only led to "increasing" traffic jams; the Xidan level overpass has not gotten rid of traffic signal control and special local environmental requirements...
