Every user should be able to use their own vehicles, which are created bevor by ac3d for example.
It would be great to define some standard routes for example “passengerexit – Ramp X” or “Gasstation – Gate Y”. The tool must be able to “drive” our vehicle along the defined routes by using bezier-lines und turning the vehicles.
On the other hand there must the possibility to define situations, when to start movements. For example: 1. Situation: My plane stands at Ramp X and the engines ist stopped – 2. Reaction (defined route): A vehicle (bus) drives from the Parkinglot to my plane- 3. Reaction: The Bus waits some minutes – 4. Reaction: The bus drives to the passengerexit – 5. Reaction: The Bus returns to the parkinglot. Perhaps there may be a possibility to define periodic situations (for example: every 5 Minutes a policecar crosses the APRON). Absolutely great would be a possibility to define situations, when an animated object will start the animation. (For example: 1. Situation: Plane stopps – 2. A lift truck follows a defined route to the plane 3. The lift truck will be animated (lifting up and down) 4. The lift truck drives an another defined route back.)

Thinking about it and writing some thoughts down I imagine that I have a hell of wonderful ideas to bring life in or wonderful (with WED designed) airports.
