The Research And Implement Of Traffic Information Service On Mobile Terminal-oriented

With the rapid development of economy in our country, as well as penetrationincreased significantly, at the same time make traffic road network has become increasinglycomplex. Because of the traffic system pressure is too large, easy to cause traffic congestion,frequent traffic accidents, traffic environment worsening social problems to be solved. Withmodern communication technology, mobile technology, data transmission technology andthe development of embedded technology, intelligent transportation system arises at thehistoric moment, has become a solution has a certain effect.Source of subject of this paper is to "support the car networking connectioninformation and service platform to demonstrate the application of vehicle", is by thenational ministry of cooperation with faw qiming information co., LTD. Iot special funds tosupport the project. Vehicle information terminal is not an independent network inside thecar, the car is no longer an independent individual, through the Internet technology, smartcars can be a social network carrier. So, in order to handheld terminal and vehicleinformation terminal, to be an effective carrier of the social transportation information,through the contribution of the user, so that the real-time accurate real-time trafficinformation; And through the secondary development on the map of a third party, thepublished real-time traffic information.This paper first introduces the background of the project sources, analysis of thecurrent domestic and foreign research trends and the present situation of the social network,which is proposed based on sharing of traffic information service research significance.Introduced the Android system framework and key components, including the Activity,Service, BroadcastReceiver, Intent, has carried on the technology and multi-threadmechanism, concurrent processing system used for solving problems.The function of the system development process, this paper firstly introduces the designfor correlation function of the mobile traffic information service platform of the terminal. Itincludes map chat, traffic information (such as traffic congestion, dangerous), the functionof positioning, communication with design. The design mainly involves the center serverand mobile terminal logic framework selection, communication protocol, communicationformat selection and analysis, Json data format for transmission of database storage design. Secondly, in view of the different design, realizes the main functions of the platformmodule, including multi thread mechanism, communication services including the mainclass, user interface design, GPS positioning function implementation and core businessscheduling process. Finally, complete the relevant functions involved in requirements.
