Traffic adaptive safety handover control method and system, computer device and medium

Abstract

The application discloses a traffic adaptive safety switching control method and system, computer equipment and a medium, and belongs to the technical field of intelligent traffic, comprising the following steps: constructing a lattice fluid dynamics model, performing linear stability analysis to obtain a critical condition; periodically judging whether the current traffic flow state tends to be unstable based on the critical condition; when the current traffic flow state does not satisfy the critical condition or the traffic oscillation amplitude in the current traffic flow state exceeds a preset threshold, generating an adaptive safety switching controller enabling instruction; activating and running an adaptive safety switching controller based on road network geometric characteristics according to the adaptive safety switching controller enabling instruction; and feeding back the control signal as an additional adjustment term to the flow evolution equation of the lattice fluid dynamics model, so as to obtain a closed-loop control optimized lattice fluid dynamics model. The method improves the anti-interference ability, overall stability and driving smoothness of intelligent networked vehicle traffic flow in a mixed geometric road network environment.
