Re: [sumo-user] WG: AW: multi-lane area detector (e2) value retrieval bug
|
Hi,
can you please post the output of traci.getVersion() /
libsumo.getVersion() on both systems?
Thanks!
Best regards,
Michael

Hi Mirko,
sorry for the delayed feedback. Working with sumo version 1.19, it seems
that the problem persists only in Windows 11 not in Linux (Ubuntu).
Best regards,
Manos

Hi Manos,
on my side it looks fine. Are you sure you use the fresh libsumo
version? The change in source code is not related to libsumo/TraCI
itself but to data storage of detectors, so there shouldn't be any
difference on how you access the data.
Best regards
Mirko

Hi Mirko,
It seems that the problem is resolved in Traci, but it persists in
libsumo.
Best regards,

Hi Manos,
you are absolutely right. The problem has been fixed in the
Github repo (see issue #13966
<https://github.com/eclipse-sumo/sumo/issues/13966>). Please
build sumo from Github source or wait for the development
version binaries
<https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version> of tomorrow. Thank you for reporting!
Best regards
Mirko

Mirko I found what is the fault. If you set file="NUL" inside
the e2 detector definition, the last interval occupancy does not
work (returns always zero). This is not the case for e1
detectors where last interval occupancy works in both cases (set
"NUL" or give an xml path). If you still need a sample scenario
let me know.

Hi Manos,
I cannot reproduce the problem. Our TraCI tests regarding
lane area detectors do not show anything similar. Would you
be willing to share a sample scenario and your TraCI script?
Best regards
Mirko

Hi all,
I have created a corridor where I have placed a multi-lane
area detector (e2) with a period of 300s and I want to
retrieve last interval occupancy via traci or libsumo. In a
previous project, I have done the same with induction loops
(e1) and it works as follows. If the detector has a period
of 300s for example, the interval occupancy is the running
mean within the period of 300s. When the simulation time
modulo (%) the period (300s) is 0 the interval occupancy
becomes zero and the last interval occupancy value is
updated. Within the period the last interval occupancy
remains constant. It seems that there is some bug in
multi-lane area detectors when it comes to the last interval
occupancy value retrieval because it always remains zero. I
have provided a printed output for 898 seconds (1 - 899s).
The first column is the simulation time, the second is the
last step occupancy, the third is the interval occupancy and
the fourth is the last interval occupancy. The results are
the same for traci and libsumo.
Best regards,
Manos
