If you want to detect the horizontal or vertical point of conflicts between a vehicle and surrounding infrastructure select the command Collision Detection.
In the drawing select the edge of the object you want to verify the possible clash points. If you move or change the base polyline, which defines a longitudinal road section the clash detection will dynamically refresh.
You can adjust the vehicle`s path through manipulation of points along the travel way to create a vehicle`s route without conflict`s points.
