In Simutrans, the fastest method of transport will get all the passengers. However, in real life, people will take long-distance buses or trains instead of planes because it's cheaper, more scenic, or they enjoy a slower pace. How could we simulate this in Simutrans?
By introducing more complex methods. Unfortunately that is quite resource hungry. Try searching the forum for quality of service (qos) or alternative routing for discussions and lots of technical details.
Actually, only in Simutrans-Experimental does the speed make a difference. In Simutrans-Standard, which route that people take is more or less random, although the route with the fewest interchanges will be selected.
I support this idea. I already proposed it for business/leisure passengers, or for passengers grouped by wealth (using building level) or combining both.
i would like passengers to use both plane and train to go to 2 cities, according to predefined criteria.
