With the rapid development of intelligent transportation technology, traffic infrastructure has become increasingly automated and is widely distributed across urban areas, requiring 24/7 operation. One of the most significant threats to these systems is lightning-induced surges, making lightning protection for traffic control systems critically important.
Traffic control systems primarily consist of power distribution systems, control systems, display systems, video surveillance systems, sensing systems, and communication networks. Key equipment requiring protection includes traffic signal controllers, power distribution cabinets, LED displays, traffic lights, network cameras, industrial switches, and radar systems. To protect these electrical devices effectively, beyond installing lightning rods on poles and establishing proper grounding systems, the most crucial measure is defending against induced lightning surges. This involves identifying the surge intrusion pathways for these devices, which primarily occur through power lines and signal cables. Therefore, protection efforts must focus on these two channels.
For power line protection, primary surge protective devices (SPDs) are typically employed, with the maximum continuous operating voltage (Uc) matched to the local grid conditions at the project site. For signal lines, SPDs compatible with specific interface types—such as RJ45 and RS485—should be selected based on the signal protocols. Additionally, power and signal lines in traffic control systems must be routed separately and shielded. By integrating shielding, grounding, and multi-stage SPD protection, the risk of lightning surge damage can be minimized to less than 1%, ensuring robust protection for the entire traffic control system.
