Connected and automated transport systems (CATS) are expected to be introduced in increasing numbers over the next decades. Moreover, they are expected to have considerable impacts on mobility, safety, the environment and society as a whole. One of the aims of LEVITATE is to forecast these impacts.

Deliverable 3.1 of LEVITATE presents a taxonomy of potential impacts of CATS. The taxonomy makes a distinction between direct, systemic and wider impacts. Direct impacts are changes that are experienced by each road user on each trip. Systemic impacts are system-wide impacts within the transport system and wider impacts are changes that occur outside the transport system, such as changes in land use and employment. Moreover, a distinction is made between primary impacts and secondary impacts. Primary impacts are intended impacts that directly result from the automation technology, whereas secondary impacts (rebound impacts) are generated by a primary impact.

Within LEVITATE, impacts are discussed for various so-called sub-use cases (SUCs). These SUCs reflect applications or interventions -related to passenger vehicles, urban transport or freight transport- that can be implemented by policy makers. Examples of SUCs are the provision of dedicated lanes for AVs, point-to-point automated urban shuttles, and automated freight consolidation.

The impacts for the SUCs are estimated by comparing the situation with intervention to the situation without intervention, i.e. the baseline scenario. The baseline scenario reflects increasing penetration levels of connected and automated vehicles (CAVs).

One of the systemic impacts that is considered in LEVITATE is road safety. Road safety is affected in various ways by increasing penetration levels of CAVs and the sub use cases. This article discusses in which ways road safety is affected by developments related to CATS and how the impacts are quantified within LEVITATE.

LEVITATE has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 824361.c
