Hydrodynamic traffic flow models and its application to studying traffic control effectiveness

-The present research was motivated by the arising difficulties in rational traffic organization the Moscow Government was faced in the recent years. The decrease of the roads handling capacity in the centre of the city (the Boulevard ring, the Gardens ring) caused by the increase of traffic density brought to necessity of re-organizing the traffic flows and constructing of the third ring road around the centre of the city. The present paper contains the results of investigations on mathematical modeling of essentially unsteady-state traffic flows on ring roads. The developed mathematical model is not limited only by the substance conservation equation and empirical relationships between density and velocity, but contains both the continuity (substance conservation) and momentum equations. It presents a closed form mathematical model and suggests the procedure to develop the model parameters based on technical characteristics of the vehicles. Thus, the available experimental data on the traffic flows observations is used only for validation of the model.
