Re: [sumo-user] Netconvert: importing "extra" OSM attributes
Hi Jakob, thanks for the explanation. I made the bus lane and the lane numbers work. However, regarding the detectors, I disagree with you. The monitoring stations are actually defined on the nodes in JOSM. So in my opinion, they are similar to traffic lights.

Re: [sumo-user] version problem
If you can use the option without error then it works. You could run the same inputs with different seed values and compare the generated route files to check the effectiveness of a particular value for random-factor. Am Do., 10.

[sumo-user] Measuring Capacity of a Lane
Hello, I ran a simple experiment to measure the capacity of a one-lane signalized exit ramp that is 1500 feet long. The result came out a lot higher than expected. The capacity came out to be roughly 1,100 veh/hr. (I was expecting to see around 750~800 veh/hr since the ramp is signalized). Is this a typical capacity value in SUMO? I've also included a brief scenario settings and methodology below. The goal was to measure the capacity of a one-lane exit ramp which is 1500 feet long. A signal (G:50, R:70) is placed at the end of the exit ramp. A single vehicle type was used with minGap=2.2 and tau=1. The speed on the exit ramp is 24.59m/s (approximately 55mph). A few iterations were done with various traffic flows. Each iteration was run for 4500 timesteps where the vehicle count of the last 3600 timesteps was collected (first 900 timesteps were a warm-up period). e3detectors were placed right after the signal and 'vehicleSum' was used to get the vehicle count for the 3600 timesteps. The maximum count out of all iterations was determined to be the capacity. Any help would be greatly appreciated.

[sumo-user] Netconvert: importing "extra" OSM attributes
Dear all, I have a question regarding the attributes, more specifically 3 attributes, one can import from OSM using NETCONVERT. 1) loop detectors: I was trying to import the traffic detectors form OSM which I have added manually as monitoring stations using JOSM. But I can't find a way to import them in my network or as an additional file. Is it possible to import them at all? 2) One other issue is the number of lanes. In JOSM one can add a key to differentiate the number of lanes in opposite direction (lanes:backward). But I think NETCONVERT reads only the key "lanes" to get the number of lanes in both directions. 3) Bus lanes are also defined with a key "lanes:psv" in OSM. However, the vehicle types allowed/disallowed on the lanes are not affected by this key. The bigger problem is actually to find a platform where several people can edit large networks together.

Re: [sumo-user] misbehaviour of LuST simulation
Hello, I don't know about the ContextSubscription part of it, but the reason why you should "only use version 0.26 for the LuST scenario" is because I built and validated the mobility with it. Newer versions of SUMO have better and improved mobility models and the congestion levels in parts of the city are very different. This is actually what I think is happening with the different number of vehicles. If SUMO cannot insert the vehicles due to congestion, they sort of time out and get discarded. Hope it helps.

[sumo-user] misbehaviour of LuST simulation
Dear user group,
I experienced misbehaviour in my LuST simulation. The problem is that
the simulation I ran recently has way more traces than anticipated. I
will attach the source code (extracttraces.py) for the simulation as
well as the lust.config.
Basically I want to generate traces over one day and insert them into
some database. Also I use the ContextSubscription feature to see if the
vehicles are within observation radius of some specific junctions (the
50 with most traffic throughput).
When I ran the simulation a few months ago I got about 209 Mio traces
with 214315 different vehicles. Unfortunately I can't determine the
source code and config of this simulation, but it should have been the
same as I use now.
However when I run the simulation now I get more than the double amount
of traces (427 Mio) with slightly less vehicles (213424).
So somehow the new simulation generated way more traces which is very
unfortunate.
By comparing the both databases I found out that both of them have
roughly the same amount of trace within the simulation time 0s < time <
6s (around 90 Mio traces).
At some point after this the new database and the old one diverge in the
number of traces.
(6s < time < 86400s : old : 120 Mio, new 338 Mio traces).
So something is going wrong there but I can't figure out what it is.
It could be that I ran the old dabase on an older version of sumo. The
new one is running on sumo 1.6.0.
I recently read that I should only use version 0.26 for the LuST
scenario, but it is hard to imagine that this misbehaviour comes from
different versions.
However, if you have any advice for me I will be glad to hear from you.
Kind regards
Knut
