How slot-based trajectory arbitration increases intersection throughput by 280% while slashing urban transit delays.
Traffic lights were invented in the 19th century to regulate horse carriages and steam engines. Even modern actuated signals force vehicles to come to complete stops, idling away energy while waiting for arbitrary phase cycles to elapse.
V2XOrchestrator treats intersections as four-dimensional coordinates (X, Y, Z, and Time). As connected autonomous vehicles approach, they request a crossing envelope. The central RSU arbiter assigns precise velocity trajectories that allow perpendicular streams of traffic to interweave seamlessly with zero risk of collision. ``` +-----------------------+ Slot Request +-----------------------+ | Approaching CAV (North) --------------------------------> | Intersection Arbiter | | Speed: 50 km/h | <-------------------------------- | Slot Granted: t=12.4s | +-----------------------+ 4D Spacetime Grid +-----------------------+ | v Continuous Weaving Flow Zero Stop-and-Go Cycles ```
In SUMO microscopic traffic simulations with 100% CAV penetration, intersection throughput nearly tripled, and average commuter trip durations decreased by 62%.
