Quote from: sami on March 12, 2013, 07:19:17 PMFor the current test scripts, this was built earlier. The airport catchment area is a variable (monthly updated) value between 50 and 250 km, based on the number of passengers the airport has transported during the current game year (or previous year in case of january). Catchment happens only in the same country where the airport is - so far.However; the 250 km may be too large for some countries, if you see the image below, where we have a 250 km ring around LHR .. goes all the way up to Manchester. (almost; as it does not catch fully the square where Manchester is, but very close to it anyway)
Quote from: sami on March 12, 2013, 08:03:35 PMAnother small example from the case of overlapping airports.In the image below we see Western Finland. It has three airports, Vaasa (VAA) - Kokkola (KOK) - Seinäjoki (SJY) . Each will have a 50 km catchment range and each of them will reach to catch the one lone square in the middle, marked in blue. Well, firstly there's the need to calculate the destination where they wish to travel from that blue square. There are some 65 000 people living inside that blue area, and we'd need to calculate how often and most importantly where they wish to travel. This is the separate, most difficult, process. Let's skip it for now and assume from that square 100 people wish to travel to capital Helsinki every day. How would the people in the blue square choose their airport of departure?This process would be kept rather simple preferrably...
Quote from: sami on March 13, 2013, 09:11:04 AMYes, it would of course immensly help in the volume and number of calculations, if we'd leave out alltogether the aspect of "X people from this square wish to fly to square Y - how do they get there" (as that would mean scouting the routes and connections etc). (..of course here the demand would move over time to the airport that has some service, but this does not take into account if airport 1 has service only to some remote airport, while airport 2 has services directly to their desired city/square - airport 1 would still show request for the flights there, even though in reality everyone would go to airport 2... ..but it's simplified)So instead of doing a list of all the squares (destinations) people would fly from this single square (approx 10000 values), we'd have only 1 set of values per square which is "how many people will depart from this square" (three parts in that data: holidaymakers, business pax and visiting family etc. (+cargo)).

Would of course like to include as much of aspects and data into it as possible, but the calculation amounts get limiting very quickly - and on the other hand even if it isn't that complicated would anyone even notice.
Quote from: Dasha on November 23, 2013, 08:32:16 AMSorry to bring a dead topic back to life but I have a few questions regarding this city based demand.1. What will be the major difference between it and the current system and 2. What will happen to quirky airports like Baku, Tashkent, Vanuatu, Guam, which all have higher demand than IRL. Will these airports become 'normal', meaning no more ULH and LH business?
Quote from: exchlbg on November 25, 2013, 01:39:57 PMI didn´t hear of any relevant industry that would push Vanuatu into the first line of airports serving business travellers nor would it be able to host a dense network of local and international lines by geografical position alone. So my answer would be no. Base demand between the centers of economy will determine the logical position of potential hubs, so the world will not turn into a complete fantasy playfield. Since I am not in the development team I am combining the little information that could be obtained through the forums during the last years. I can´t predict how the new demand model will work precisely .
