Ray tracing and static obstacle maps can be used in the operation of a vehicle. Sensor data of at least a portion of an external environment of the vehicle can be acquired. A dynamic obstacle in the external environment of the vehicle can be detected based on the acquired sensor data. In response to detecting a dynamic obstacle, it can be determined whether a secondary occluded area is located behind the dynamic obstacle relative to a current location of the vehicle based on a static obstacle map. Responsive to determining that a secondary occluded area is located behind the dynamic obstacle relative to a current location of the vehicle based on a static obstacle map, a driving maneuver for the vehicle can be determined based on at least the dynamic obstacle and the secondary occluded area. The vehicle can be caused to implement the determined driving maneuver.
