This paper describes part of the results of the ongoing CEDR-funded 'FALCON' project, which aims to introduce a step improvement in road freight transport efficiency in Europe through the definition of a new performance-oriented legislative framework, and thus ensuring a proper match between vehicles and the infrastructure. A Smart Infrastructure Access Policy (SIAP) is being developed as the primary method of regulation, in which policy explicitly specifies the performance level required from the road freight vehicle with respect to safety, maneuverability, infrastructure loading, and environmental impact, while considering national topologies and operational conditions. The vehicle combinations, which are expected to operate within SIAP are in this paper validated against the number of criteria being, the infrastructure damage and deterioration, congestions, safety, and the effect on the modal split on national and cross border basis.
