2002 - UNECE - Trans-European Motorway Design Standards

Produced by the United Nations Economic Commission for Europe (UNECE), these standards were elaborated under technical guidance provided by the countries participating in the Trans-European North-South Motorway Project (TEM) and were adopted by the Steering Committee of the Project.

The role of these standards is to ensure that the planning and design of the TEM motorway provide for the adequate traffic flow at minimum operating cost, while ensuring harmonized conditions for motorway users, proper level of service, safety, speed and driver comfort over medium and long distances.

Covers all aspects of motorway design.
