(1) the same grade roads intersect, usually maintain separate longitudinal gradient unchanged, and change the cross slope. Regularly changing longitudinal slope of small cross section of the road switch road Ridge gradually moves toward the larger longitudinal road carriageway line, making it cross section cross slope and larger longitudinal slope longitudinal gradient of the road.
(2) main road and secondary roads intersect, the cross section of the main road were unchanged, while minor roads cross section of double, a gradual transition to the main road and found consistent longitudinal cross section, to ensure that major road transport.
(3) when you design should have at least one longitudinal direction depart from the intersection of the road to facilitate drainage.
(4) the intersection range layout when rain, rain water should not flow through the intersection of the road crossings, or another road gullies should be set before the crosswalk or low areas.
(5) the intersection design elevation should be consistent with the floor height of the surrounding buildings.
