Abstract

The invention relates to a traffic information inquiry and VOD system and method that faces the Smartphone, the system comprises a background traffic information grid, a Smartphone client terminal and a wireless communication network. The system provides local service which organizes, requests, transfers and stores the vector map data at the Smartphone terminal, so as to realize local service request; the system further provides background service that the Smartphone terminal realizes real-time communication with the background server terminal via the wireless communication network and requests dynamic traffic information; the background traffic information grid server responses to the request, processes and sends data; the Smartphone terminal receives the dynamic road condition data, draws a map reflecting the variation of the dynamic road condition according to the road condition data, and finishes the background service VOD such as dynamic (static) shortest path, dynamic road condition exhibition and parking lots inquiry. The beneficial effects of the invention are that rich real-time, dynamic traffic information inquiry and VOD service are provided for the users on the Smartphone, favorable man-machine interface is realized and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a system and method for Smartphone-oriented traffic information query and on-demand broadcasting. Background technique [0002] With the development of today's cities, traffic information plays an increasingly important role in people's lives, and powerful and convenient traffic information query and on-demand methods have become an urgent need. Grid technology provides background technical support for the complex calculation of traffic information, while the application of mobile devices such as PDA, Smartphone and vehicle embedded system provides a convenient query platform, so that people can know traffic information well anytime and anywhere. [0003] Smartphone is a new generation of mobile embedded platform proposed by Microsoft. It is based on Windows CE 3.0 operating system, integrates the functions of PDA and mobile phone, and provides friendly human-computer interaction and powerful data processing capabilities. Howe...
