Boarding-only stops, intercity route settings, etc... November 26, 2008, 08:29:39 pm I was asked to post this FR, since the original author can't/doesn't want/whatever.In short: when loading things onto vehicle, cargo to farther locations should have higher priority, since it ensures higher profit. If cargo to near stations is loaded first, vehicle can unload it soon and complete the rest of route empty. Quote Selected

Re: Load first p****engers (cargo) to farthest destinations Reply #4 – November 26, 2008, 10:23:22 pm I can imagine the advantages/disadtvantages of both systems.If you have a system where you have 2 schedules to the end destination, one of them skipping most stations while the other as stoptrain (AH vs ABCDEFGH) then it would be nasty if the stoptrain gets filled with ppl wanting to go to HIf you have a system where schedules share a part of the same route and then go their own way (ABCDEFGH vs ABCDIJKL) it would be most beneficial that the farthest destinations get filled first.I generally tend to use the 2nd system more than the first one so I would be in favour of this.However if it's something that could be set as an option of a line: support^2.

Re: Load first p****engers (cargo) to farthest destinations Reply #5 – November 26, 2008, 10:24:24 pm At least untill a few years ago, Simutrans had behaved so I think. But it was changed, because some people complained that express trains have few p****engers.For example, if you have two train routes as the following.Express A - - - - - - - - - FLocal A - B - C - D - E - FAnd A and F are larger cities obviously (this is why express trains serve these stations).In this case, if the local trains pick up long distance p****engers first, then the local trains will be filled up with p****engers going to F and are less likely to carry p****engers to B. And the express trains will have less p****engers. But of course, if you don't have express routes, this would be more efficient. Quote Selected

Re: Load first p****engers (cargo) to farthest destinations Reply #9 – November 27, 2008, 09:31:09 pm Not really, the load first is way more efficent. The old system was load first waiting goods first. That way, if your stuff wait really long, it was almost never loaded, since new stuff was inserted at the list top. Quote Selected
Re: Load first p****engers (cargo) to farthest destinations Reply #10 – November 27, 2008, 09:56:09 pm Hm, but what we are discussing here is a system working exactly opposite to the current. When I can, I will look at code, maybe it can be as simple as iterating backwards from end? Let's hope Quote Selected
Re: Load first p****engers (cargo) to farthest destinations Reply #11 – November 27, 2008, 10:19:44 pm You must iterate twice: First make sure you are not p****ing the same station twice and then start from before that entry. Apart from that things woul dbe identical. But since it break the concept of express lines, I would rather say, that this is not the right place to fix problems which are the innermost incentive to gaming. Imho, it is the task of the player to upgrade capacity, that this problem is solved (and a direct line would solve it with the current system, while with the proposed system all intermediate stops will be clogged until there is overcapacity on the express route).

Re: Load first p****engers (cargo) to farthest destinations Reply #13 – November 28, 2008, 04:06:18 am Both ways (old and new) have problems, because both can lead to starvation (if there is a steady flow of high priority people/goods, low priority ones accumulate). That's a known problem with static priorities.A (somewhat) crazy idea just occurs to me: - Take p****engers/goods of the group with higher number waitingIf a vehicle is at A and its route is A-B-C-D and the people waiting to go to B is 100, to C is 300, to D is 200, take people going to C.

Re: Load first p****engers (cargo) to farthest destinations Reply #16 – November 29, 2008, 12:13:39 am This is a different problem, in my opinion.If the total amount of generated p****/goods generated is over the capacity of the transport system to deliver it, p****/goods will accumulate, no matter what will be given priority.The problem addressed is different. If priority is only based on distance to the station, it is easy that some vehicles steal p****/goods from other more specialized ones (express trains, quick connections, ...), no matter the way we give priority. Giving priority to accumulating goods, those vehicles will steal p****/goods only if there is a lot.Think the other way around: if we serve the smallest quantity, then all goods for the big city/consumer will not get completely through as well.

Re: Load first p****engers (cargo) to farthest destinations Reply #17 – November 29, 2008, 01:55:27 am Unfortunately, I'm talking about the very problem addressed in this thread.Take an example above.Express A - - - - - - - - - FLocal A - B - C - D - E - FAnd let's ****ume A is the largest city, while F is the second largest.With the current loading system, convois serving the local services take p****engers going to B, C, D, and E first and they carry p****engers to F if there is any spare capacity, but they don't need to. Therefore, the number convois seving the local line can be minimal. And the convois serving the express line simply need to carry the leftover of the local services. And the number of the "leftover" is relatively stable.But with your proposed loading system, local services will be likely to be filled up with p****engers going to F first, because the number of p****engers going to F is simply larger than that of p****engers going to other destinations. This means the number of convois serving the local line will be surely larger than the above case to carry all the p****engers to B - E. In addition, express route will become less profitable, since the number of "leftover" will fluctuate, depending on which p****engers the preceding local convois load first.In short, your proposal will be likely to reduce the utilisation rate of the convois.

Re: Load first p****engers (cargo) to farthest destinations Reply #18 – November 30, 2008, 05:28:33 am I'm not convinced about what you say. For two reasons:In your example, the main objective of the express line is to take care of that surplus. So, if there is accumulation of those p****engers, simply increase the number of vehicles of the express line. Local line vehicles will help only when there is surplus for F. If they keep helping too much and the number of vehicles are enough (that second clause is the difference between our positions, I think), the number of p****engers to B, C, D, and E will grow and take precedence (aging mechanism)The second reason is choosing another example in which C is the large city and the express line goes directly to C: A --> C. With the present system and following your same reasoning D, E, and F will not be served. Am I right?Though I may be wrong. My intuition tells me that if I had a transportation office and packets for a certain destination accumulated, I would try to send them asap in whatever vehicle that could handle them.I think the best way to test it is making a patch. If I have time, I will try and see. Just curious about if my intuition is right or wrong. Quote Selected

Re: Load first p****engers (cargo) to farthest destinations Reply #20 – November 30, 2008, 10:25:47 am QuoteThe second reason is choosing another example in which C is the large city and the express line goes directly to C: A --> C. With the present system and following your same reasoning D, E, and F will not be served. If C is a large city, then I would have an express service which skips B like A---C-D-E-F and local service between A and C, because most p****engers to D, E, & F originate from A and C and the number of p****engers between A and C is large. I could add non-stop services only between A and C as well, if neccesary. Anyway, there is no point to operate long distance local services, if there is an express route, because it's a waste of money. Quote Selected

In which order you do that is irrelevant.B) For the express-connection to work you need the current system (start loading with p****engers for the nearest stop).General conclusion:The current system is the best of all the alternatives.If the connections are not working well (p****enger overflow at stations or vehicle load percentage way under 100%) tune the capacity of the connections. Fiddling with loading orders won't help you. Quote Selected

Re: Load first p****engers (cargo) to farthest destinations Reply #26 – December 01, 2008, 10:14:20 am to Combuijs:You don't have right. There is situation C), usual in city local traffic:there are two lines:LONG: A-B-CSHORT: A-B (because there is more p****engers to be transported between A and B)Then the problem is, that I could not influence the timetable. When comes the LONG line first, it loads p****engers from A to B and is full between A and B, and empty between B and C. The SHORT line is then empty between A and B (because p****engers used the LONG line).Do you understand? Quote Selected
Re: Load first p****engers (cargo) to farthest destinations Reply #27 – December 01, 2008, 11:23:20 am QuoteDo you understand?Yep, I do. It's a valid example. I personally would have solved this by making two lines:A-BB-C (or A-C, or even both)which is far easier to configure in terms of capacity. But your example may have advantages as well (no extra hop for p****engers).So two solutions make sense: load nearest first and load farthest first. The other two (taking lowest/highest number of p****engers for a destination first) are only useful when you are lacking capacity, so they can be better solved by increasing capacity. Quote Selected

Re: Load first p****engers (cargo) to farthest destinations Reply #29 – December 01, 2008, 01:22:41 pm The best would be treating the p****enger with their arrived order.

Quote from: hradtom – on December 01, 2008, 12:08:18 pmThe switch to load nearest/farthest destination first should be useful. The switch should be defined for the line.I have to disagree with being able to switch the load nearest/farthest depending on the line. P****enger are to be served and not to be "ordered" to take or wait until which train. I see this way.We can not afford to treat p****enger in their arriving order because of process power of cpu. VThen we've decided to treat from the nearest ****uming that's p****engers behavior as customer. VForcing p****engers behavior seems little odd from my view of this simutrans. I believe as one company, they should treat customer evenly. Not prioritizing some of them to the interest of company. Company should work to follow the customer's behavior. Quote Selected
