I mean, how do I use that information to improve my network, or it's only for information when somebody goes to adjust their timetable they can reference what is going on currently and then make adjustments?
Well, it's mostly informative of what's the schedule setup will do.
You setup starting at 6 to 18 with an interval of 1h, you will see at each line between 6 and 18 the nice number "00". Meaning at 06:00, 07:00... 18:00 a bus will start the line at stop 1.
For easy interval of if you have little setting on each option (weekday, rush, night, weekend) it's almost useless, but if you mix many things with short interval, it helps a lot to see how much vehicule will be starting at which hour.
Then, you can use it to improve stuff but it gets complicated.
Lets say you have a tram line feeding a metro line. You want the passenger of the tram to be able to "jump" in the metro without waiting long but only at some specific hours because you know there are many people at that time.
First, you go to check when the crowded tram arrive at the stop normally. To do that, you look at the line window with the list of stop. Next to the stop, there is a time like 2h05. This means that the tram is supposed to arrive at this station 2h05 after the tram started according to the timetable.
You then look at the timetable and look for the correct departure. let's say it's 9:00 (rush hour). This means the tram will arrive at the stop at 11:05 or around.
Now, we know when the tram arrive, And we want to make sure a metro will pass around 15 minutes after (time for the passenger to go to the station. So at 11:20 there should be a metro there.
This time, you check the time for the metro to reach the station. Let say it's 1h35.
11:20 - 1h35 = 9:45
So you must have a metro starting at 9:45. Easy to set this up, you go to the metro timetable to change the start time or interval (depending on what you exactly want) in order to have at line 9, written 45 meaning that a metro will start its duty at 9:45.
Hurra, you have a link with no waiting time for the passenger.
Note : it's a bit overkill and I hardly see that being really worth doing the math for most cases.
