Intelligent traffic system(ITS) is a development trend for urban modern traffic.Active guidance control for urban traffic can relieve increasing traffic congestion pressure effectively.FCD(floating car data) based dynamic guidance for urban traffic is one of the directions of traffic control research.To meet the real-time demand for massive FCD processing,an FCD parallel computing based dynamic traffic guidance approach is presented and implemented.The FCD properties are analyzed in detail.An FCD parallel computing based dynamic traffic guidance system is developed on KD-50-I-E platform.Experimental results demonstrate the effectiveness and feasibility of the proposed approach.
