Local Control Procedure
Modern signaling systems adapt to the traffic situation, for example adjusting the green times to suit the relevant traffic volume. Siemens provides different traffic-actuated local control methods.
Individual and Capable of Growth:
Funtion and User Library PDM e (extended for C940/C900)
The phase-oriented PDMe-control method is the flagship of Siemens control processes. The individual programming option is combined with a variety of functions and user libraries.
Libraries save valuable time with readily programmed and tested functions and solutions for a multitude of applications. Tailored solutions are also available:
In addition, users may archive, name and combine their personally defined components with the PDM components. Sitraffic Office-Language is used to easily link up components. The “individual code” of the relevant user comprises all pre-defined functions: both the PDM libraries as well as the user-defined user libraries. In this way, the component library grows with each completed project, saving a great deal of time in future projects – and thus money.
Parameterizing Instead of Programming:
Control Logic S-L e (Extended for C940/C900)
Standardized and flexible all the same? This is no contradiction. Our strategy: simplification by standardization – with Sitraffic Office-Language and S-L. The single components are already combined here. The user only needs to adapt the components to meet the specific requirements of the relevant intersection – simply via parameterization.
The operation is extremely straightforward: Programming knowledge is not required for any of the process. Even for special cases or large deviations from the standardized components, Office-Language offers tools for an elegant and quick solution.
Controllers and Traffic Computers Finely Tuned to Each Other:
Frame plan calculation supported by M-Xe (extended for C940/C900)
The central adaptive network control, Sitraffic Motion, is increasingly gaining in importance. One component in network control, the local M-Xe module, can also be used for regular planning with PDM e and S-L e and support planners with automatically generated frame plan calculations. In this way, signal control can be optimally prepared for Sitraffic Motion MX.
Standardized Control Procedure VSPe(Extended for C940/C900)
The software package contains a standardized, parameterizable control method. This makes it possible to benefit from traffic-actuated control without the need to develop a conventional user program.
