Investigating Traffic Effects of Control Transitions in Level 3 Conditional Driving with SUMO
summary
SUMO motorway simulations model Level 3 takeover requests with a calibrated Berlin corridor and show that even successful control transitions raise time headways, cut capacity, and increase surrogate-safety events; notable capacity loss begins at 10–15% market share and travel times inside the ODD rise 20–60% under unmanaged operation. A managed takeover-timing scheme reduces but does not eliminate losses, safety measures (using TTC and modified deceleration rate) change by up to a factor of five with management.
