交通信号控制机与上位机间的数据通信协议
Application Summary AI generated
This standard specifies the data communication protocol between traffic signal controllers and upper-level control centers, defining message formats, data encoding rules, and transmission procedures. It is applied in urban traffic management systems to ensure interoperability between signal controllers from different manufacturers and central control software. The standard is used during system integration, testing, and daily operations of intelligent transportation systems (ITS) for coordinated traffic signal control.
