In order to verify the accuracy of the discrete traffic flow model and find out the most suitable statistical method of data for model validation, the discrete traffic flow model proposed by Robertson which was suitable for urban arterial between the intersections was studied. The traffic flow of five roads in Beijing city was investigated by multi-spot photography. The traffic flow data were collected at different time intervals according to 1–6 s and verify the discrete traffic flow model proposed by Robertson at different statistical intervals. Finally, the error of the model in different statistical interval of 1–36 s was obtained. The mean and variance of the error were analyzed and the optimal time interval of the survey data in this model was 1–5 s. This conclusion was verified by T test.
