Urban (and regional) vehicle access regulations (UVAR), such as low emission zones (LEZ) and limited traffic zones (LTZ), are critical in sustainable urban mobility and freight policy. Panteia together with partners Armis, AustriaTech, CORTE, MAPtm, TRT and  Sadler Consultants, will address several challenges related to their implementation, especially in the context of information provision and enforcement of foreign vehicles or drivers in the UVARExchange project.

Communication to drivers will be improved by addressing the need for EU-wide harmonised physical signs and variable message signs for selected UVARs, as well as by demonstrating the provision of information to the vehicle via Cooperative Intelligent Transport System (C-ITS) messages. Further, the project will address the cross-border sharing of vehicle and driver information, which will on one hand, allow the automatic compliance check of foreign vehicles and drivers, reducing the need for pre-registration (and related fines). On the other hand, with access to driver information, cities will be able to effectively enforce traffic fines on non-compliant vehicles.

The project is a European Parliament Preparatory Action, funded by the European Parliament and contracted by DG MOVE. The outcome of the project, which involves both desk research and four demonstrators in multiple EU cities, will feed into legislation and support cities in their initiatives to implement UVARs in their mobility planning.

First workshop: Cities and Stakeholder Workshop, 13 December 2021


Last Monday 13th of December, we had our first “UVAR Exchange Cities and Stakeholder Workshop”. The online event addressed two key informational challenges in the effective implementation of UVARs, namely:

  • Drivers need timely information about the terms and procedures for compliance as they approach the UVARs.
  • Cities and enforcement agencies need information about the compliance of vehicles and information about the vehicle holder/owner/driver to effectively enforce the UVAR.

The workshop focused on three main topics to address design, engineering, legal and administrative aspects of the challenges: 

  • Session 1: Physical signs for UVARs
  • Session 2: C-ITS messages with UVAR information
  • Session 3: Cross-border exchange of vehicle technical and owner data, supporting the enforcement of UVARs 

If you wish to check again the discussions that were held during the workshop, you can find here all the links to the recordings of the sessions:

Survey on enforcement of UVARs against Foreign Vehicles

UVARExchange is gathering information about how cities are currently ensuring UVAR compliance of foreign vehicles and how they are able to effective enforce them. In the former, this primarily involves getting information about the vehicle, for instance whether it meets the emissions standard requirement of the LEZ. In the latter, it is about ensuring that enforcement agencies can obtain information about the vehicle driver, owner or holder, when an UVAR infringement occurs.

The responses will be used to develop solutions to the issues and revise legislation to enable the use of the solutions.


UVARExchange participates in the CIVITAS Forum 2021

An UVAR-dedicated session was organised, where four projects were presented and discussed.  ReVeAL  Dynaxibility4CE project UVARBox and UVARExchange were present in the session. Lucy Sadler representing UVARExchange presented the project.

The presentations of the session can be viewed here.
