Project Background As a core commercial area of Hangzhou, the Wulin commercial district sees over 200,000 visitors daily, with frequent vehicle traffic. In such a high-density environment, traditional management methods face three major challenges: safety hazards from oncoming vehicles at intersections, low efficiency in guiding tourists, and insufficient waste management capabilities. These issues collectively restrict the service quality and development potential of the commercial district, urgently requiring a smart and comprehensive management solution.
