Tonka, you keep advocating for your pods system. The challenge with that is still the volume of devices needed and the cost to develop and implement. If the monorails service approximately 12-15,000 people per hour (probably high, but that would at least be max capacity) and your pods held even 10 people, you would still need close to 500 of them just to make people wait less than 15 minutes. Would they all have separate tracks? Presumably they would all run on a few circuitous tracks, and then you are back to the problems the monorail faces - what if they break down? What happens to the pods behind them? If they are at ground level, what happens when one hits an animal, or a car or bus (this is why monorails are elevated)? What would the cost be up front? If the system in Vegas (more like a monorail I know) cost over a billion, the level of complexity of the pods would have to be higher.
I still think the monorail is the best approach, but I wonder if something more like the tomorrowland trasnsit authority would be a better solution. Rapid deployment and constant flow would be advantages, but you still face the problems of them crossing traffic or what if one breaks down, and then we are back to - Why replace the monorail at all?
