Public bus plays an important role in resolving urban traffic congestions.The study has selected such indexes as: line length,network density,repetition coefficient,non-linear coefficient,stop density,average distance between stops and stop coverage for the evaluation of public bus in Beijing with the support of GIS technology.It has been found that there are still some problems in the bus network,although public bus in Beijing has been greatly developing,especially in recent years.The problems revealed in the study are that the length of the line is too long on the whole and the network density is low relatively.Both the repetition coefficient and its difference in spatial distribution are large,and the indexes of non-linear coefficient,stop density and stop coverage are not consistent with the standard values.The results can help to present reasonable countermeasures and optimized projects for improving public bus efficiency.
