Abstract:

Assuming that the car’s speed is constant along the road segment, the traffic platoon dispersion model was developed from the perspective of flow. The parameter of peak range of variation coefficient of the predicted and actual arriving traffic flow distribution was chosen for model evaluation. Besides, the influence of data collector location, link segment length, traffic volume and flow direction on the predicted results was analyzed. Comparing with the static average speed model, the results show that the data collector location and the link segment length have a trivial effect on the prediction model. The trend of the model performance was summarized for different volume levels and different flow directions. It can be concluded that the proposed model is effective and available for predicting the distribution of traffic flow arriving at downstream intersection based on the simulation experiment and field investigation.

Key words:intelligent transportation; vehicle infrastructure communication; feedforward control; coefficient of variation; traffic platoon dispersion model
