Researchers introduce V-STC, a multi-vehicle coordination method that reduces temporal occupancy while maintaining collision-free separation

A new approach called variable-time-step spatio-temporal corridor (V-STC) treats both spatial configuration and time durations as decision variables to enhance temporal efficiency in multi-vehicle autonomous vehicle coordination.

The method constructs a V-STC for each autonomous vehicle, then plans a dynamically feasible trajectory independently for each vehicle based on the generated corridor.

Simulation studies show the approach achieves safe multi-vehicle coordination and yields more time-efficient motion compared with existing STC approaches.
