Siemens and Cohda Wireless collaborate on C-ITS infrastructure

Siemens AG and Cohda Wireless have announced they will collaborate in the area of Vehicle to Infrastructure (V2I) communications. The objective is to share information between vehicles and roadside infrastructure such as traffic lights, to increases the quality and reliability of information available to drivers about their immediate environment, other vehicles and road users.

RSESiemens AG and Cohda Wireless have announced they will collaborate in the area of Vehicle to Infrastructure (V2I) communications. V2I devices are part of Cooperative Intelligent Transport Systems (C-ITS), which share information between vehicles and roadside infrastructure such as traffic lights. This increases the quality and reliability of information available to drivers about their immediate environment, other vehicles and road users.

Siemens expects to globally deploy transport infrastructure such as overhead sign gantries and traffic lights in its V2I roadside units (RSUs). RSUs are 802.11p WLAN-based radio modules that transmit information such as speed limits, warnings of icy roads or other dangerous situations, traffic jams and construction warnings within a fraction of a second to passing vehicles and traffic control centers. The successful adoption of vehicle to infrastructure technologies is expected to significantly reduce traffic congestion, reduce vehicle accidents and lower auto-related pollution.

Under an agreement signed by the companies, Cohda Wireless will develop and produce RSUs for Siemens, enabling this ‘smart infrastructure’ to communicate with connected vehicles. It will also see Siemens base its Sitraffic ESCoS RSU upon Cohda’s MK5 V2X family, using NXP’s Roadlink chip sets.

Siemens is a provider of mobility solutions and Cohda provides hardware and software of V2I technology. Siemens will deploy Cohda’s technology for various ITS field tests and pilot projects, including the A58 motorway in the Netherlands, A9 motorway in Germany, and the Living Lab in Austria.

Siemens’ Sitraffic platform is a road traffic management platform. The Siemens Sitraffic ESCoS RSU will be able to communicate important information to and from cars and larger vehicles equipped with V2X technology. Cohda Wireless provides hardware and software development services and products for the roadside units, based on Siemens’ ITS knowhow and development specifications.
