| Abstract: | Based on the component importance and reliability of public transport network,the node importance and road unit importance are analyzed to improve the operation of public transport network.Using the integrated benefit of the system as optimization objective,and traveling time as restriction,an optimum model of public transport network is built.Then,an example is given to illuminate the network adjustment. It makes a higher public transport system reliability. |
