It's a fundament feature of the next generation dynamic navigation system to support Real-Time Traffic Information(RTTI).Based on the existing hierarchal road model of navigation electronical map, this paper proposes an uniform method for multilayer road coding and a Dynamic Hierarchal Road Model(DyHiRD) to improve the efficiency and correctness of RTTI storage.Experimental results show that this model can satisfy the requirements of dynamic navigation application in large cities.
