# Hybrid Multi-Lane Spatial Logic

 Title: Hybrid Multi-Lane Spatial Logic Author: Sven Linker (s /dot/ linker /at/ liverpool /dot/ ac /dot/ uk) Submission date: 2017-11-06 Abstract: We present a semantic embedding of a spatio-temporal multi-modal logic, specifically defined to reason about motorway traffic, into Isabelle/HOL. The semantic model is an abstraction of a motorway, emphasising local spatial properties, and parameterised by the types of sensors deployed in the vehicles. We use the logic to define controller constraints to ensure safety, i.e., the absence of collisions on the motorway. After proving safety with a restrictive definition of sensors, we relax these assumptions and show how to amend the controller constraints to still guarantee safety.
