The invention discloses a spatio-temporal big data trajectory analysis platform and method, a server and a storage medium. The method includes: searching for spatio-temporal large data, displaying station location distribution and traffic information, predicting station traffic based on neural network algorithm, searching and displaying relevant trajectory information of measured object in presettime period according to space-time big data, searching and displaying station information whose access frequency of measured object exceeds preset frequency threshold in preset time period accordingto space-time big data; according to the spatio-temporal big data and the association relationship between each object, according to the preset rules, searching the other objects related to the measured object; searching the object and the related location information accompanying the measured object according to the spatio-temporal big data; according to the preset trajectory similarity rules, searching the object similar to the measured object trajectory in the spatio-temporal large data. The invention can effectively improve the reliability of the spatio-temporal big data analysis, and caneffectively improve the social security risk analysis and prediction ability.
