A method and system for a large-scale real-time traffic index service based on a distributed framework, which provides a more accurate, useful traffic information service for the vast numbers of travelling users. The system is divided into a resource layer, a user service layer, an application scheduling layer, and an information interaction and display layer; the resource layer provides infrastructure resources; an index computing layer invokes a plurality of computing nodes for computing resources in the resource layer, processes traffic index data source data using a distributed framework, and after computing, stores same in an unstructured database; the user service layer invokes the user data stored in the resource layer to complete the corresponding user service content; the application scheduling layer receives various user requests sent by the information interaction and display layer, invokes the index computing layer and the user service layer to complete the user requests, and feeds back the request results to the information interaction and display layer. The method comprises the four steps of traffic index real-time computing, user service interface response, application service request and distribution, and information display service. |
