Abstract

With the development and perfection of AIS system, AIS data with high timeliness, strong stability and wide coverage provide a strong data base for traffic flow statistical analysis. This paper use Java with full consideration of JVM performance, to achieve rapid AIS data decode, then put forward a new method to improve the efficiency of spatial and temporal data query. The main contents of this paper as follows: (1) This paper use reflection, multi-threaded mechanism to simplify the program structure to ensure thread independence and the atomic nature of the abnormal isolation, the use of random non-blocking IO storage technique to speed up data storage, reduce memory usage. (2)extending Geohash and Base32 encoding applications, propose a method to compressed search space, thus improving the query efficiency.
