(2-Erin) Traffic Volume Settings

The following would be nice if possible: Slider/spinbox to control traffic volume Transverse pedestrians for crosswalk scenarios Not sure how we would do this, but traffic slowing/stopping for intersections would be cool Comment from user: "Make Primary/Secondary option for sections with pedestrians so you can add multiple types of pedestrians ((walking/walking, walking/jogging, jogging/cyclist...) including increasing volume). This will only work if you can figure out how to offset the starting point of pedestrian assets because if not they will walking on top of each other or side by side in step." Make sure the vehicles spawn at the beginning of the section by default but randomly in the middle when turning traffic on and off and opening a save file. Currently when you open a save file with the traffic paused the cars start paused at the beginning and cut in half by the clipping plane.
