Optimization of Public Traffic Network Based on Power Function

Power function was applied to studying the optimization of urban public traffic network.An optimized algorithm was presented.The urban public traffic network optimization principle and the factors of urban transport network were presented,the principal objective function of public traffic line network optimization was put forward by using principal components analysis.The criteria for appraising every optimized target were designed according to their powers.Then,the evaluation function was constructed based on the power function,which was solved.The application results show that the model not only meet the transport demands,but also implement the environment protection objective.
