【Abstract】 With the increase in the number of personal vehicles,traffic congestion in the cities become more and more severe,development of public transport to ease traffic problems is one effective way.In order to optimize the public transportation network in existence,effectively use the traffic source and solve the city traffic problems,through the analysis of principle and objective of optimizing of public transportation network,it was established several linear optimization models for public transportation network.Also,the writer establish a direct traveler density model for the problems which was existed in public traffic of Luoyang.更多还原
