    Abstract
  • A new iteration framework of estimating OD trips is established by a stochastic shortest path multi path assignment model to calculate the probability matrix P based on the two improved definitions of effective path and effective link.Meanwhile a hypothesis argumentation is put forward to examine the feasibility and rationality of the iteration method.Then the factors of influencing result of estimation are discussed.Finally two important conclusions resulted from P are obtained.
