Description
Technical field
The present invention relates to grade separation technical field, specific field is multiple exit tolerance grade separation.
Background technique
This reality is with the improvement of living standards, resident trip becomes more diverse, in terms of the trip quality such as comfortable, quick
It is required that also higher and higher.Super expressway (such as highway, city expressway) and other roads carry out crossings on different level, not by traffic
Signal interference is driven a vehicle continuously along victory, is favored by traveler.Grade separation is as the essential element of super expressway, and vehicle is vertical
Bank of Communications is sailed can encounter this problem often: being unfamiliar with due to the carelessness of driver or to road conditions, lead to miss outlet, vehicle must not
Without long-distance detour return correct road, or do not stint it is illegal drive in the wrong direction return to former outlet.This single exit design is to friendship
Logical participant brings the inconvenience of extreme, on the one hand, the detour of long range increases travel time cost, and to a certain degree
On increase the traffic pressure in other sections, on the other hand, on super expressway driving in the wrong direction, there are major safety risks, to lives and properties
Safety causes larger threat." reasonable " demand for considering traffic participant, for this purpose, it is proposed that multiple exit tolerance grade separation.
