Study on Key Links of Data Release in Chinese TMC

The government and enterprises, in China, set out to cope with the congestion problem using effective solutions about intelligent transportation systems. Not only do they slow down transportation pressure but also make response to green travel, energy conservation and emission reduction. This is a new digital ecological engineering. Traffic Message Channel is regarded as a complete set of Intelligent Transportation System in releasing the dynamic information in real-time manner. It is currently the most popular solutions about transportation congestion. It makes great contribution for digital ecological engineering. This paper will analyze the process of data release. It is crucial to think about new contents of key links of data release in a complex environment of Chinese special transportation infrastructure construction and the uncertain collecting way. There are three main aspects such as data fusion, data matching, data releasing. We put forward reasonable approaches to deal with problems that we encountered by in-depth research on three main aspects. The experiments verified the feasibility of schemes which can improve the accuracy and efficiency about TMC traffic information releasing and provide the technical reference.
