CEDA Tunnel Positioning

Navigation using satellites in tunnels does not work reliably because the satellite signal does not reach the required quality.

Incorrect localization and navigation instructions coming at the wrong time can cause many stressful and dangerous situations, including traffic accidents.

In addition, choosing an inefficient route can unnecessarily burden traffic in some locations. In addition to unpleasant waiting, this increases the risk of traffic accidents and produces emissions and noise.

The infrastructure comprises small batterypowered devices that are installed on the tunnel walls. They do not require a connection to the electricity or communication network.

CEDA offers to install and operate the localization infrastructure and make it work directly in well-known navigation apps like Waze and Google Maps.

CEDA also provides the necessary support for the developers with CEDA Open API. It allows implementation of improved localization in other navigation apps and also allows to make C-ITS functionality available in tunnels.

Tunnels are very expensive structures that are meant to ease traffic and reduce congestion.

With CEDA Tunnel Positioning it is possible to use the tunnels more efficiently. Thanks to improved drivers’ navigation it reduces drivers’ stress, minimize unnecessary traffic, additional noise, and emissions.

With this solution, you can avoid situations where drivers make sharp turns, reverse, or even turn around. These situations occur because the drivers didn't have enough time to react to navigation instructions or they didn’t receive any instructions due to localization not working properly.
 

By implementing CEDA Tunnel Positioning in tunnel control systems it is possible to gather information regarding drivers’ positions. This information can be further utilized during emergencies or to be shared with rescue squads.

This communication channel can be used to provide useful information to connected drivers’ apps based on drivers’ actual position. They can receive information about speed limits, lane setups, warnings, evacuation instructions, and much more.
