With the traffic stream data collected in the exit ramp downstream of south Ruijin road locating in the Shanghai inner loop expressway, traffic parameters of traffic speed, density, occupancy and volume are analyzed. The time variation of speed and volume, the difference of traffic volume participating rate in the various lanes of road section downstream, the selection and evaluation of density-speed model and the relationship among traffic density, speed and volume are key-points analyzed. The research can provide data support and scientific basis for the design and planning of urban expressway.
