C-Roads Belgium (Wallonia)


The main objectives of the C-Roads Wallonia pilot is to operate and assess the deployment of a cloud based solution for co-operative ITS services, to connect road users with Traffic management centres (TMC) and allowing TMC to directly interact with the end users. The pilot will bring the opportunity to expand or upgrade Traffic Information Services and Traffic Management Services offered today, building on a digital ‘virtual infrastructure’, feed and support a discussion on the future role of the public road operator.

The SOFICO is financing an extensive ITS strategy from 2017 onward to renovate and increase C-ITS systems along its highway and road network. A new traffic management centre has been recently equipped with a new traffic management system. Wallonia wishes to modernize its traffic management based on the newest technologies through different interfaces for data collection, data management and for road user information.

As member state of the C-Roads platform, Wallonia is participating in the testing and implementing of harmonised and interoperable C-ITS services. Through a Partnership in between SOFICO, Tractebel and ITS Belgium, two pilot projects for C-ITS use cases deployment will be implemented on part of the Wallonia highway network.

  • For the first one, the focus has been placed on the ITS - G5 technology : 5 RSU’s have been installed on the A602 junction as well as a C-ITS messages server. The A602 junction hosts important traffic volumes and features major security issues since it consists in an urban environment highway featuring a succession of tunnels and bridges through the city of Liège.
  • For the part based on cellular communication (4G) technology, after having considered the development of a specific own application, it has been decided to work with Coyote, a service provider already active on the Belgian market.The pilot will be deployed along approximately 427 km of Walloon motorways via the Coyote community.
