The project links to and follows the European Parliament funded UVARBox project. It has a number of aims on the exchange of information.

Firstly, to enhance the experience of road users by improving the communication of information to drivers in the vicinity of UVARs through different road signs. By communication to drivers on different UVARs, UVARExchange works to enable EU-wide harmonised physical signs working with EU organisations responsible for road sign coordination, as well as variable message signs (VMS) , as well as by demonstrating the provision of information directly to a connected vehicle via Cooperative Intelligent Transport System (C-ITS) messages.

Secondly, UVAR Exchange will address the cross-border sharing of vehicle and driver information. Enabling this would avoid the need for foreign drivers and vehicle operators to pre-register for separate LEZ cities and countries. The only reason this is currently needed is when cities cannot get cross-border information sharing of the vehicle technical information from other countries. Enabling this cross-border sharing would at the same time make compliance checks and enforcement of foreign vehicles and drivers by the UVAR authorities easier, cheaper and quicker.
