Traffic flow efficiency

The traffic flow efficiency impact area addresses the impacts of CCAM on collective traffic patterns, travel times and throughput on a road network.

Traffic flow efficiency describes the ability of the road network to serve the required demand for travel and transport without unnecessary delays. This impact area covers the effects of CCAM on average travel times and delays of different road user groups, on the throughput of roads, and on the resilience of road networks in terms of recovery after interruptions. Traffic flow characteristics emerge from the behaviours of and interactions between individual drivers and vehicles (driver-vehicle units). The interactions create patterns that are independent of an individual’s behavioural details. This impact area thus concerns the movement of a group of vehicles or the traffic stream as a whole, rather than individual vehicles alone.

The next figure shows the main components of the traffic flow efficiency impact area.
