Construction for the city taxi trajectory data analysis system by Hadoop platform

To analysis the taxi trajectory data, an unified intelligent transportation platform which is based on Hadoop and massively parallel processing technology is constructed. In the intelligent transportation platform, the design model, function modules, technical scheme and SGD algorithm are proposed. Combining with the operation of the vehicle data, the platform realizes data analysis for vehicle trajectory, empty car, and passengers. The platform also can allocate the resources of taxi effectively and help government to planning and analysis of the hot taxi route.
