Transport activity and fleet composition

The transport activity and fleet composition impact area addresses the impacts of CCAM on the total amount of realised travel and transport as well as on the number and types of vehicles used.

Transport activity refers to the total amount of realised travel on a road network over a certain period. It can be expressed in terms of vehicle kilometres travelled (VKT), passenger kilometres travelled (PKT), or tonne-kilometres travelled (TKT). It results from the movements of people and commercial transport of goods  subject to the constraints posed by service supply  and network conditions.

Transport activity covers potential effects of CCAM on the total VKT, PKT or TKT. This includes changes in modal split and spatial and temporal distributions both within and outside the operational design domain (ODD) of the CCAM system. Vehicle fleet composition focuses on how CCAM influences the total number and characteristics of the vehicles in the transport system.

The next figure shows the main components of the transport activity and fleet composition impact area.
