Ideal decision-making method of urban public traffic line network optimization

On the basis of considering each factor of urban public traffic line network, the optimization function expression and the restricted conditions of urban public traffic line network were presented. Based on ideal scheme's definition, the schemes were arranged in simple order according to the distance between each scheme and ideal scheme, so the decision-making model for the optimization of urban public traffic line network was presented. Applied results indicate that the method improve the used ratio of urban public traffic line network, optimization results accord to the real situation, the method is feasible.
