As an important part of urban traffic management, traffic signal equipment is highly valued by the state for its safety. Our country has strict laws and regulations and advanced technical protection measures in terms of network security and traffic management to ensure the stable operation of the traffic signal system. Relevant national departments will conduct regular security inspections and maintenance of transportation facilities to prevent any potential cyber attacks. The public can rest assured that our country's traffic management system is safe and reliable. At the same time, we also call on the majority of Internet users to abide by laws and regulations, not to participate in any behavior that may endanger network security, and jointly maintain a good network order.
