A traffic flow hierarchy induction algorithm based on VANET

The centralized traffic flow induction algorithm has the disadvantages of high computational complexity and large information delay. The distributed traffic flow induction algorithm has the disadvantage of local optimization. For the above two characteristics, this algorithm proposes a traffic flow layered induction algorithm (TFLIA). Firstly, "stratification" means that the algorithm sets up a two-layer control center. The first layer is at the level of the independent scheduling area. This center plans the travel path of the vehicle nodes. At the entire city level, this center controls the transit path of the traffic flow. Two levels of synergy induce traffic flow. Secondly, this paper proposes a short-term prediction and data decision analysis algorithm to induce the vehicle nodes to enter the planned path. Finally, the algorithm carries out the traffic flow induced simulation experiment. The experimental results show that the algorithm can balance the global flow of traffic flow, reasonably induce traffic flow and alleviate traffic congestion.
