Enhancing the multi-scale capability of the backbone is a crucial technique for designing traffic sign detection, and the multi-scale fusion structure is the key approach to improving the algorithm for small target detection. Therefore, we made enhancements to the existing ResNest backbone by constructing hierarchical residual-like connections within each single radix block. This effectively boosted the multi-scale representation ability of the backbone.
