Sitraffic control centers from Siemens ensure smooth data flow and fail-free communication, whether between heterogeneous systems or when field devices from different suppliers are connected – because our outstations and instations offer maximum integration capabilities.
Outstations and Instations
Seamless data exchange in urban traffic engineering requires full compliance with the relevant standards. Interfaces and standards from Siemens offer tailor-made solutions for your traffic management facilities. Outstations ensure smooth communication between field devices; instations enable communication between different control centers.
OCIT (Open Communication Interface for Traffic) is an open standard for road traffic control systems. Siemens is actively involved in the OCIT initiative. All Sitraffic control center systems and controllers support this open standard.
The VDV standard is used by public transport vehicles to sign on and off at intersections in the scope of PT prioritization schemes. This standard allows wireless communication between the vehicle and the intersection controller. The data are used to give priority to public transport.
The TLS communication standard describes the technical terms for the supply of outstations, especially for use on interurban highways. The TLS interface can also serve to supply urban traffic control systems with traffic information and data on current VMS contents and environmental conditions.
OCPI is a comprehensive interface that allows fast and cost-efficient integration of other systems. In addition, interface converters enable communication via other standards such as WanCom, TLS, DAV, DATEX II, VDV etc.
These interfaces cover virtually all interface applications within traffic management systems. The standardized interfaces OCIT-C for communication between components and systems at the control center replace the previous interface generation, i.e. OCIT-I process data and OCIT-I supply data.
TMC is a standard for the transmission of location-specific, digital traffic reports. Our control centers can receive and generate, edit and forward digitalized traffic reports in the TMC format.
DATEX II is a European standardization initiative for different applications in the area of traffic data and traffic information. The Siemens center supports communication via this standard, in line with project requirements.
The new Sitraffic Canto communication system offers the most advanced communication technology currently available for traffic control applications. Canto is short for “Communication in advanced new technology in outstations”. The system allows you to continue using your existing traffic controllers, including legacy systems designed to BEFA 5 standard, while providing the basis for the use of modern technologies such as DSL, OTN, fiber optics etc.

Growing traffic volumes, increasing air pollution, rising costs: A mobility solution cannot solve all your infrastructure challenges on its own. But it will always contribute to making your city or municipality even more modern, more attractive and more environmentally friendly.
Siemens interfaces and standards ensure maximum ease of integration and seamless communication with field devices and between control centers.
