Application of Inverted Function to Alignment Optimization Design of Interchange Ramp
For adopting to the difficult terrain and restricted conditions, a probability of using the concept of inverted function into interchange linear to optimized design is built, which use the inverted function y=a/x as the interchange right-turn ramp linear. This function can be corresponded to the vehicle trajectory, decrease the area and cut the cost of interchange compared with the ordinary way“spiral-circle-spiral”.By the analysis of how to use this function linear to be ramp, this paper get the way to set the ends of the ramp by circular curve or spiral curve. And this paper also take application example to illustrate the specific solution of how to use the inverted function to set the interchange right-turn ramp.
