The practice of urban transportation at home and abroad , the fundamental way to solve the urban traffic congestion problem today is : give priority to the development of public transport . In this paper , by reading a large number of domestic and foreign literature , drawing on existing research results , combined with the actual situation of Ningbo , find out the weak areas with lines in Ningbo City public transportation network that suit the status of Ningbo public transportation network optimization method , to improve the status quo of Ningbo city bus . Public transportation network optimization studies do support requires a lot of basic data , this paper uses a combination of methods of the bus investigation and the IC card data analysis , access to the research needs of residents travel data to ensure the accuracy and applicability of the research results . Through the the urban trips structure survey combined the Ningbo city bus statistical data, analysis of the development and reform of the status quo in Ningbo city bus and bus technology , performance, service level status , so as to arrive in Ningbo city bus . Based on GIS technology , Ningbo city bus network into traffic area , transport cluster analysis, diagnosis Transportation District bus network service levels in order to find the services are weak in the area of Ningbo City public transportation network . The same time, the weak areas for various types of wire mesh corresponding optimization of ideas , improved line of traffic within the network service levels . Select a line length of this article , the non-linear coefficient , day trip visitors to the clustering factor , through cluster analysis , the diagnosis of the technical performance of the Ningbo City bus lines , on line each category analysis , the status quo bus lines in line . Line for all types of problems , optimization program, to enhance the technical performance of the line . Taking into account the complexity of the bus lines , specially selected representative Ningbo City bus lines 809 as an example, to do a single line optimization study . Traffic analysis, the passenger flow analysis , benefit analysis , to determine the optimization program , ideas and methods for the optimization of Ningbo City bus lines .
