In this report, the autors applied the N-th power traffic flow model, U=U_f〔1-(K/K_j)^N〕 to the traffic flow data. The parameter in the model was estimated by the mean free speed, U^* and mean free density, K^*. U^* and K^* were estimated by the critical time headway, t_c and we adopt 4.5sec. and 9.0sec. as t_c. The traffic flow data were gathered according to three difference time intervals 1min., 3min. and 5min. The three traffic flow data showed similar tendency.
