Autonomous Vehicles Steer Cities Into the Future
Insights from a “Nature” Interview with Professor Christos Cassandras
Christos Cassandras, Distinguished Professor of Engineering, Head of the Division of Systems, and Hariri Institute Faculty Affiliate at Boston University, is helping shape the future of autonomous transportation through a vision of connected, cooperative vehicles.
His research, highlighted in a recent Nature report, examines how connected autonomous vehicles (CAVs) could improve safety and efficiency. By communicating position, velocity, and other operational parameters with one another and sharing this data across a networked transportation system, CAVs could better coordinate movement, reduce collisions, and enable smarter traffic flow in urban settings.
His work uses various approaches that allow CAVs to negotiate maneuvers and reward actions that improve overall traffic flow, such as allowing another vehicle to merge. While challenges remain, particularly in preventing misuse, he emphasizes that meaningful benefits do not require full adoption. Even a small number of connected vehicles could help smooth traffic by subtly influencing how surrounding cars behave.
