Research on Highway Short-term Traffic Simulation Based on Measured Data Fitting

In this paper, we analysis a short-term probability distribution of steady-state traffic flow that are based on field observations and establish a cellular traffic simulation model conforming to the reality, propose a model based on measured data fitting and the model is suitable for the short section traffic of microscopic traffic simulation. simulating with the traditional method and comparing with the measured data ,the model obtains a good effect.
