Cohda Wireless V2X-Locate demonstrated in Bjørnegård Tunnel Norway


March 2018, A successful trial of a vehicle positioning system was carried out in the Bjørnegård tunnel in the municipality of Bærum by Norwegian tunnel technology company Aventi, in partnership with Cohda Wireless.   The purpose of the trial was to demonstrate the efficacy of Cohda Wireless’s world-leading vehicle positioning solution, V2X-Locate, in the newly-built 2.2km tunnel.

V2X-Locate was developed by Cohda to solve the problem of accurate vehicle positioning where GNSS (GPS) systems usually perform poorly, for example in urban canyons, underground carparks and tunnels.   Four of Cohda’s Road-Side Units (RSU’s) were positioned at intervals inside the tunnel and following a range of tests, Cohda’s V2X-Locate solution was proven to be able to locate a vehicle moving through the tunnel with a high degree of accuracy, as captured in this video.

The trial paves the way for the introduction of reliable Cooperative Connected Automated & Automated Mobility (CCAM) and Cooperative Intelligent Transport System (C-ITS) technology services in tunnels which make up 1400 kilometres of Norway’s roads.
