Traffic systems might change soon...
To enable/disable cars and/or change the standard speeds: computer -> traffic.
To prevent movement/spoawning of specific vehicles in specific areas: create restriction zone in map editor.
For spawning and operation of automatic cars and vehicles the traffic points have to be placed in the world. If a vehicle doesn't find another traffic point in front of it then it will despawn.
Traffic points can be linked to the next point by right clicking with the same item. Each traffic point can have multiple connections.
Following traffic points don’t have to be connected but can be connected.
Traffic points which are not aligned must be connected.
Traffic will NOT spawn between connected/linked traffic points!
