# Priority Crossing
A priority intersection is a pedestrian crossing that is not controlled by traffic lights. At a priority crossing, vehicles will slow down and continue through if there are no pedestrians on that crossing. Otherwise, they will stop and wait for pedestrians to pass.
To create a priority crossing go to **Settings Window -> Intersection Setup**
If **Show All Intersections** is checked you will see the intersections from the entire scene. If unchecked, only the intersections visible in the scene view will be displayed. Using the **View**, **Edit,** and **Delete** buttons you can perform the respective operations on each intersection from that list.
Press **Create Priority Crossing** to create a new road crossing. This will open the Priority Crossing Setup Window.
**Hide Waypoints** - will hide the scene waypoints offering you the possibility to select different objects inside the scene.
To select the waypoints for the vehicles to stop press **Assign Road Waypoints.**
Select the waypoints where you want cars to stop. Selected waypoints will be marked with red circles.
When the selection is finished, press the **Done** button.
You can add more waypoints by using the **Assign Road Waypoints** button.
You can delete a waypoint by using the **Delete** button.
Using the **View** buttons, you can focus the scene view on the selected waypoint.
To control the crossing based on your pedestrian behavior you can use the API[SetPriorityCrossingStopState](/mobile-traffic-system/complete-api/setprioritycrossingstopstate.md). Set the stop to true, and the vehicles will stop allowing the pedestrians to cross.
