This paper introduces MakSafe, a formal framework designed to verify safety rules for automated vehicles using semantic zones and trace-tree reasoning rather than uniform time steps. By enabling executable checks for scenarios like front-vehicle identification and time-to-collision verification, it addresses the scalability challenges inherent in validating autonomous driving systems against open-world traffic variability. The approach offers sub-millisecond rule checking performance across varying traffic densities and prediction horizons, providing a rigorous method for ensuring compliance in autonomous vehicle logic.
MakSafe: A Spatiotemporal Semantic Framework for Formal Specification and Compliance Checking of Road Vehicle Safety Rules
arXiv:2610.19735v1 Announce Type: new Abstract: Scenario-based validation is essential for automated road vehicles but cannot cover the full variability of openworld traffic. We present MakSafe, a formal spatiotemporal framework for specifying and checking road vehicle safety rules through semantic zones, action-based forecasting, and trace-tree reasoning, avoiding uniform time discretization. We formalize the road network, vehicle states, and occupancy zones, then build executable rules for front-vehicle identification and timeto-collision (TTC) verification. The evaluation combines a tracedependent case study with a scalability benchmark over traffic density (N ), horizon (H), and branch factor (B). MakSafe yields branch-specific verdicts, deriving safe and unsafe outcomes from the same initial scene, and re-evaluates a scenario after a control update. A single rule check stays well below a millisecond across the reported sweep, and longer horizons slow the TTC check.
