bill_gensheet in post 136706 said:If it is as little as ~1 second, is that not near the cycle time for SimSig to recalculate things ?I don't think 20m is significant. 20m is one second at 45 mph. The logic involved in an ACOA happening or not happening involves various different bits of code that aren't all run at the same time. So anything within one second of the train reaching the signal is not a bug, it's just a fact of life. Think of it as the driver looking at one of the instruments at just the wrong moment. If the ACOA happens two seconds before the train reaches the signal, it should be reported. If it happens two seconds after the train reaches the signal, it should not be reported. If either of those are violated, that's a bug. Anything that happens in that 4 second window is going to be marginal and I'm not going to spend weeks trying to adjust the code to deal with it without breaking any of 50 other features.

The train can still be in the track section but past the signal. Hence in my original post it is separated off under the comment "Noticed the following while doing those tests, not sure if it might be relevant." and "Similar E behaviour on other sims too:" and listed the propagation behaviours for several signals. As long as this is not the loophole through which the ACOA gets missed then it is indeed a red herring. As such I did my tests on trains in both directions on Motherwell (only) for the lack of ACOA calls. Log in to reply |

clive in post 136754 said:[quote=bill_gensheet;post=136706]If it is as little as ~1 second, is that not near theThe initial post was that either the train should ACOA at SIG1 (say for seeing G to Y) OR at SIG2 for being R having had a G at SIG1. Either is OK, but neither still seems wrong to me. Assume 4 aspects plain line. I got messages of (or similar to) "1M97: unexpected aspect 2 at SMC826 after seeing 6 at SMC822" The above shows that the aspect change has been detected at 'SMC826', but I follow your logic and fair enough no ACOA there. However the expected aspect at SMC828 (the next signal) should then be 'no worse than YY'. SMC828 is R. Is it the case that at SMC828 the train is still happy because it has 'remembered' SMC826 as being a Y, as the main code for that is done every second ? Would explain why the train slows down from SMC826 not just from 'seeing' SMC828. Log in to reply |
