There is a horizontal line (starting at 20 minutes, then continuing at 22 minutes and finally ending at 19 minutes) that indicates the scheduled route section time.
There are five wiggly lines that indicate the required route section time for
five different feasibility levels (50%, 70%, 80%, 85% and 90%. Take,
for instance, the trip starting at 12:47. Here about 50% of the trips
can be completed in 20 minutes and about 10 seconds. The current
timetable time of 20 minutes is clearly not enough. A timetable
time of about 23 minutes is more appropriate; 85% of the trips can
be completed in 23 minutes. The information about the trip of 12:47
is based on 60 recognized trips (the number above the graph).
The difference between the 70% time and the 90% time is usually
quite small.
The same information can be shown in a different format:
The horizontal axis of the graph is identical to the one in the previous graph. The vertical axis shows the percentage of trips that can be completed. In the graph, points of identical trip times are connected. The line with the white digits in blue background shows the values of the current timetable. Again we look at the trip starting at 12:47. About 45% of the vehicles is able to complete the trip in the scheduled time of 20 minutes.
