Planning method of bus main artery network based on point-area match

In order to improve the accuracy and efficiency of bus network planning, a planning method was proposed based on point-area match theory, the boundary area equation of sensible searching range was determined, and the optimization model of bus lines was set up based on considering the match between area location and passenger flow. A "from left" algorithm was applied to get the enumeration of effective bus lines within sensible searching area, the optimal line was gained by using multi-objective decision, finally the new planning method was tested with an example. Analysis result shows that the line network scheme obtained by new planning method is consistent with the real line network scheme, the accuracy and efficiency are greatly improved because the searching process is greatly simplified by giving the key controlling point and effective area, so the method has practicability.
