CoEXist:“Automation-ready” new German Study

The mission of CoEXist is to systematically increase the capacity of road authorities of getting ready for the transition towards a shared road network with increasing levels of connected and automated vehicles (CAVs), both in terms of vehicle penetration rates and levels of automation using the same road network as conventional vehicles (CVs).

CoEXist will enable mobility stakeholders to get "Automation-ready" – which CoEXist defines as conducting transport and infrastructure planning for automated vehicles in the same comprehensive manner as for existing modes.

Approach

Automation-ready transport and infrastructure planning in cities is a key precondition for fulfilling the promises of CAVs to reduce road space demand and improve traffic efficiency and safety. CoEXist will address three key steps in transport and infrastructure development:

Automation-ready transport modelling: Validated extension of existing microscopic and macroscopic transport models to include different types of CAVs (passenger car/ light-freight vehicle, automation levels).

Automation-ready road infrastructure: Tool to assess the impact of CAVs on safety, traffic efficiency and space demand and development of design guidance for hybrid (CAV-/CV-shared) infrastructure.

Automation-ready road authorities: Elaboration of eight use cases in four road authorities (Gothenburg, Helmond, Milton Keynes and Stuttgart), used to evaluate AV impacts on safety, traffic efficiency and road space requirements (with CoEXist tools) and making detailed hybrid infrastructure design recommendations.
