  • In order to investigate the spatial-temporal relationships of discrete spatial-temporal data, spatio-temporal trajectory was taken as a link, and an analysis method for spatio-temporal meeting of vehicles based on FCD (floating car data) was proposed. The map matching method was used to spatially interpolate FCD to attain the continuous trajectories of vehicles. A linear interpolation method based on the timestamp and trajectory of two adjacent sample points was proposed to acquire the timestamp of any point in the trajectory. The spatial meeting relationship of vehicles in different temporal relationships was discussed using the Allen's interval based temporal logic and the spatial relationship theory. Experiments on spatio-temporal trajectory acquirement and spatio-temporal meeting analysis were conducted, and the spatio-temporal meeting relationships of vehicles were discussed. The experiment results show that the proposed spatio-temporal analysis method can solve the spatial-temporal relationships analysis problem of discrete spatial-temporal data.
