Re: [sumo-user] understanding of TIMELINE defination
|
Hi Michael, more questions. Appreciated in advance!
1) If the timeline describe the relationship wih the OD matrix;
how to understand the numbers in timeline ?
image.png
the timeline is
--timeline 0.9,0.5,0.2,0.2,0.5,1.3,7.0,9.3,6.7,4.2,4.0,3.8,4.1,4.6,5.0,6.7,9.6,9.2,7.1,4.8,3.5,2.7,2.2,1.9
2) I found a document that describe the OD using the different format;

Excuse me asked so more questions!
Best regads!
Hi Jane,
the timeline should apply only to the interval defined in the matrix. I
just noted that I made a mistake in the description below. The numbers
do not refer to the number of vehicles but rather to the percentage in
relation to the input matrix.
Best regards,
Michael
