Embodiment Construction

[0029] figure 1 Among them, A is the original lane, B is the original pedestrian walkway, C is the road and bridge, D is the ramp on the upper platform layer, E is the ramp on the lower shallow tunnel layer, and F is the ramp leading to the deep tunnel layer.

[0030] figure 2In the middle, there is an isosceles triangular front and rear distance-measuring courtesy line pattern, and the line with arrows is the running line of left-turning vehicles (when it is difficult to distinguish front and rear, proceed from the kinematics principle—vehicles decelerating when turning uphill should give way to vehicles running in a straight line at an even speed ).

[0031] The best way to realize the present invention is as follows: at first make the peripheral subgrade expansion at the crossroads, encircle and excavate the deep tunnel downhill lead and a small section of tunnel as the building area on a road, excavate after laying maintenance piles, the earthwork is removed, Build the ...

Abstract

These invented traffic facilities and their construction solve the problem of vehicle congestion at road crossing caused by traffic ligths and thus keep crossings expeidite. Four construction layers i.e. road-bridge layer, up-slope platform layer, down-slope shallow tunnel layer and down-slope deep tunnel layer are extended from the original road for pedestrians and vehicles to pass through. The shallow tunnel layer is provided for non-motor vehicles and pedestrians. The platform layer gives motor vehicles ways to turn left or right or turn back, and markings are painted on this layer for drivers to judge the distance or dodge each other. The road-bridge layer and the down-slope deep tunnel layer are used by straight going vehicles so as to keep the road crossing expedite.

Description

technical field [0001] The invention belongs to traffic facilities and unimpeded engineering. Background technique [0002] Existing traffic light management traffic is roughly like this: first allow the green light of vehicles turning left on one of the roads to let go, then allow the green lights of straight-line vehicles on this road to let go, then let the other road turn into green light, and let go according to the above steps. The bigger the city, the busier the traffic, the more detailed and strict the rules (the more detailed the traffic light allocation time, even pedestrians are within the strict management of traffic lights), such a traffic light cycle takes about 2-3 minutes, which is enough time Many vehicles at the intersection cause accumulation. The current state of traffic at intersections can be summed up with a simple numerical concept. On average, only 1 / 4 of the vehicles and pedestrians can pass; 3 / 4 of the vehicles and pedestrians are stopping and wai...
