| Abstract(in English) | Floating car data systems that regard each vehicle as moving sensors and provide traffic, weather information, etc. generated by analyzing floating car data are attracting much attention. In this paper, we propose a high performance floating-car data analyzing technologies for next generation floating-car systems that have an important issue of handling of very large-scale data such as several hundreds of thousands of floating-cars' data on a national basis. To tackle the issues, we apply our data stream processing platform (DSPP) that is based on inbound processing model that data records are processed before they are stored in a repository. The DSPP has following three key technologies: (1) Dataflow architecture and pipe-line processing, (2) Successive analyzing, and (3) On-memory processing. The prototype floating-car system based on the DSPP has successfully worked. The floating-car system estimates traffic jam according to probe data of 1700 floating-taxes in Nagoya. Our experience shows that the performance of our proposal method is excellent since its processing time is only 1/160 of the processing time of a conventional system. |
