In the realm of intelligent transportation systems, ensuring the safety of vulnerable road users (VRU) has always been a critical concern. To further enhance the safety of VRU, this paper proposes a bi-directional collaborative perception method for VRU and vehicles, which utilizes Road Side Units (RSU) as intermediaries to transmit intention information between them. By sharing intention information that represents future behavioral intentions of objects, network members calculate the intention conflicts between vehicles and VRUs. While vehicles actively avoid conflicts by utilizing intention information, RSUs transmit conflict warning messages to VRUs to assist them in actively avoiding conflicts, thus protecting the safety of VRU. Finally, the proposed scheme is implemented and evaluated on a real dataset, and finds that the proposed scheme has improved the VRU perception rate, perception efficiency, and safety protection by 44%, 19%, and 37%, respectively, compared to traditional schemes.
