Outline
To address the issue that static path planning methods struggle to respond to dynamic traffic conditiond and easily cause local congestion in underground parking lot guifance, this paper proposes a parking space guidance method tailored for Intelligent Connected Vehicles (ICV). The proposed method leverages Vehicle-to-Everything (V2X) communication technology to acquire real-time information on parking space availability and traffic flow. It employs a time window model to predict potential spatiotemporal conflicts during vehicle movement and coordinates vehicle passage according to predefined priority rules. To mitigate congestion arising from these conflicts, the estimated waiting time due to conflicts is quantified as a dynamic increment to the edge weights of the affected road sections. On this basis, the D*Lite algorithm is integrated to perform path re-planning, achieving spatiotemporal cooperative optimization. Based on a model replicating a real parking structure, Simulation tests demonstrate that compared to traditional methods, the proposed approach significantly reduces the average parking search time across various scenarios with different occupancy levels within the facility, thereby effectively enhancing the overall parking efficiency.
