Abstract
An autonomous vehicle can be navigated through an intersection. Topological information about the intersection can be obtained. The topological information can include, for example, a count of a number of lanes on roads associated with the intersection, information about an entrance point to the intersection, or information about an exit point from the intersection. Based on the topological information, context information about a candidate trajectory through the intersection can be obtained. For example, the context information can be based on a current time or information about a position of an object with respect to the topological information. Based on the context information, an existence of an advantage to change an actual trajectory of the autonomous vehicle can be determined. In response to a determination of the existence of the advantage, a change to the actual trajectory of the autonomous vehicle can be caused to occur.
