The United States Department of Transportation (USDOT) is proactively addressing the challenge of developing and testing the plethora of scenarios that autonomous vehicles will encounter once deployed in the transportation system. The Virtual Open Innovation Collaborative Environment for Safety (VOICES) Proof of Concept (PoC) aims to tackle these challenges by offering a shared virtual environment on a secure network that enables vehicles and systems across the transportation ecosystem to interoperate while synchronized to common scenarios. The project allows organizations to develop and test their systems in a high-fidelity representation of the surface transportation ecosystem, sharing infrastructure and resources while still protecting intellectual property.
