Based on the analysis of shortcomings of traditional statistics research methods, the characteristics of geostatistics and its applied fields and application principles are proposed to solve the traditional research method of statistics on the floating car speed without considering its spatial structure. Meanwhile, the spatial analysis model and the solving algorithm are presented. The spatial structure and the interpolation of floating car speeds are analyzed by exact floating car speed data of the study area in Beijing in May 2005. The results show that the geostatistics as a new spatial analysis method can solve the spatial variability problems which the traditional statistics methods cannot attained. The geostatistics provide a novel idea to study spatial transportation objects, which has important reference value to macro-level transportation planning and meso-level operating characteristics of transportation system and has good application prospects.
