Optimization of highway profile based on genetic algorithms

This paper put forward a new optimization method for highway profile with genetic algorithm, which could be used to search the optimal solution in a feasible zone. It built a feasible zone according to the vertical section initial solution, and use genetic algorithms to choose the optimal solution in the feasible zone by developing chromosome concerns with the real one after another correspondence designed between the variables, to evaluae the probably solution in the feasible zone with an evaluation function(degree of suiting). The application shows that this method is capable of searching the entire solution space in order to find the global optimum; it is effective and feasible to road optimization design.
