Simultaneously, pedestrian overcrossing also can be identical with height on motorway with the height on former sidewalk, to eliminate ramp or the step road that is provided with owing to difference in height.
Secondly, on pedestrian overcrossing, can set up ceiling; On the ramp of pedestrian overcrossing, can set up shoe; The spandrel girder that supports pedestrian overcrossing can vertically be provided with, and reduces the height of pedestrian overcrossing.
Once more, the elevator for the upper and lower pedestrian overcrossing of people comprises escalator, vertical lift elevator.
Effect of the present invention is:
(1). needn't tear the roadside buildings thing open, can not construct under the blocked road, should on the existing road of city proper, reconstruct.
(2). former sidewalk is transformed into nonmotorized vehicle lane, and former nonmotorized vehicle lane is transformed into motorway, and has removed the isolation facility of former motorway and nonmotorized vehicle lane, and motorway is widened.
(3). realize the separation fully of motorway and nonmotorized vehicle lane and pavement, and cancelled traffic lights control the pedestrian.
(4). the pedestrian separated fully with motor vehicle, bicycle, eliminated the phenomenon of pedestrian and vehicle contention on the existing road, obviously improved the vehicle pass-through safe condition.
(5). can eliminate the inconvenience that the pedestrian and non motorized vehicle driver takes umbrella or wears raincoat in rain, the trip of snow sky, improve traffic safety.

Among the figure: 1. pedestrian overcrossing, 2. motorway, 3. ramp, 4. former sidewalk, 5. ceiling, 6. local isolated column, 7. step road, 8. shoe, 9. stair, 10. isolated column continuously, 11. guardrails, 12. connect bridges, 13. spandrel girders.
The specific embodiment
Among the figure: pedestrian overcrossing 1 is erected on the former sidewalk 4 of road across motorway 2, the clear height of pedestrian overcrossing 1 on motorway 4 is not less than the height of national standard autos only permission, generally be advisable to be not less than 4.5 meters, the clear height of pedestrian overcrossing 1 on former sidewalk 4 is not less than the height of the current permission of national standard bicycle, generally be advisable not to be higher than 3.5 meters, this difference in height of pedestrian overcrossing 1 connects by ramp 3 or step road 7.Simultaneously, pedestrian overcrossing 1 also can be identical at the height in different highway sections, can cancel ramp 3 or step road 7 like this, it is convenient that people are walked on pedestrian overcrossing 1, but increased the physical demands of the upper and lower pedestrian overcrossinges 1 of people, specifically can according to crossing quantity, stair 9 quantity that should build of reconstruction road, whether can be provided with factor such as elevator come fixed.
Pedestrian overcrossing 1 is being provided with stair 9 or elevator near public area, the main crossroads such as residential district outlet, commercial area, hospital or on the highway section separated by a distance, for the usefulness of the upper and lower pedestrian overcrossing 1 of people.Simultaneously, pedestrian overcrossing 1 is still setting up connection bridge 12 on highway section separated by a distance, crosses over the usefulness that road is gone to the pedestrian overcrossing 1 on opposite for people.
The pedestrian overcrossing Bridge 1 go downstairs 9 or the highway section, access of elevator local isolated column 6 is set, or a highway section under the pedestrian overcrossing Bridge 1 is provided with continuous isolated column 10, the pedestrian overcrossing Bridge 1 is gone downstairs the outer end of 9 accesss by guardrail 11 sealing, stop people to go downstairs and enter former sidewalk 4 suddenly after 9, ensure the traffic safety of bicycle.
Former sidewalk 4 is transformed into nonmotorized vehicle lane, and former nonmotorized vehicle lane is transformed into motorway 2, realizes the separation on motorway, nonmotorized vehicle lane, sidewalk like this.
Ceiling 5 is set up in highway section with good conditionsi on pedestrian overcrossing 1, for the usefulness of people's sunshade, the snow that keeps off the rain.Simultaneously, can set up shoe 8 on the ramp 3 of pedestrian overcrossing 1, shoe 8 comprises facilities such as the sliding muscle of setting up defences, embedding reeding.Secondly, the spandrel girder 13 that supports pedestrian overcrossing 1 is suitable vertically to be set to, and promptly be arranged in parallel with road, can reduce the height of pedestrian overcrossing 1 like this, reduces the physical demands of the upper and lower pedestrian overcrossing 1 of people.
Elevator for the upper and lower pedestrian overcrossing 1 of people comprises escalator, vertical lift elevator, and the highway section is good so that escalator to be set having ready conditions.
Technical scheme of the present invention extremely is suitable for the transformation of urban district existing road, transforms the traffic capacity and the vehicle pass-through security performance that can obviously improve the city existing road after finishing, and also brings convenience for people's daily walking, many benefits such as safety.
