The Architecture Model and Application of SignalML

摘要

The development of traffic signal hardware and software technology creates the incompatibleproblem among many kinds of traffic signal controllers. To realize the information exchangeamong traffic signal controllers and the traffic control systems, this paper gives outSignalML(signal markup language). SignalML is built on the bases of NTCIP applicationlevel and the XML development. It can be used to identically describe and pack and store andconvey traffic signal control data. The traffic signal control information can be exchanged andshared based on this standard among the traffic signal controllers and traffic signal controlsystems. The paper builds the architecture model of SignalML and applies the model in thetraffic signal control test platform project of Beijing city.
