Complexity analysis of function modules for traffic portals in Beijing

Considering the large number of industries and data information provided by the traffic portal, the setting up of the functional modules has a certain complexity. Based on the survey of traffic portals´ functional modules in Beijing and the comparison of the traffic portals, this paper discusses the complexity of functional modules of traffic portals and gives some proposals on how to design the functional modules. From the analysis of four different aspects, come to the conclusion that to regulate different functional modules´ settings, as well as different portals´ settings.It will help to improve the quality of its services.
