Traffic is a kind of dynamic nonlinear time series affected by various factors; the traditional predication methods can’t achieve higher accuracy, In order to improve its forecasting accuracy, In this paper, analyzing chaotic characteristics and predictability of traffic based on the data of daily rush-hour by collecting, and reconstructing the phase space, propose a method of building predication model by using weighed one-step local-region prediction method, and use the model to one-step forecast, the experimental results show that this method can better fit the change of traffic and has higher accuracy . It can provide an effective way for forecasting of traffic.
