On the basis of the information mentioned above, au-tonomous cars make decisions according to the satisfaction of the guard conditions which are specified with spatio-temporal properties. To specify these properties, we propose a BMML (Bounded Multi-dimensional Modal Logic) taking the estimated evolvement on the properties in the near future into account. In BMML, we define primitive spatial logic in a single grid with spatial properties for a car under consid-eration in our space grid model. We can describe diverse traffic situations such as block, cross and reservation with specification in BMML. To extend the view transformed from the original view of the car under consideration, we introduce navigation operators as a type of modal operator to explore whether spatial properties hold in a neighboring grid or even several neighboring grids within the bounded view. And all the navigation operators can be used as a combination to achieve a view extended in various directions to see whether a spatial property is satisfied or not. In consideration of time
