Abstract

Combining fluid mechanics and traffic flow theory, this paper proposes a new macro-micro integrated simulation method, which regards vehicles driving in the city as fluid, and calculates the density and speed of traffic flow in real time through the conservation of mass and momentum of fluid mechanics. A density field, and a speed field, are formed in urban roads; When observing at a close distance, vehicles are generated in real time through the density field and speed field for microscopic simulation. When observing from a long distance, the destroyed vehicle presents a macroscopic traffic simulation. The results show that this simulation method can perform simulations very smoothly, more realistically reflecting the road status, vehicle status, and road congestion.
