Re: [sumo-user] How to relate phase numbers and edge ids?
The phase numbers relate to the chronological sequence of the phases. You probably refer to the link indices which define the correspondence between the the state and the edges.

[sumo-user] (no subject)
Hello,
i'm trying to create a simulation where i need to do some rerouting of a
vehicle when it approach in intersection .
i tried using
traci.vehicle.subscribe("veh0", ( tc.VAR_NEXT_TLS ,))
and
raci.vehicle.getSubscriptionResults("veh0")[tc.VAR_NEXT_TLS]
to get the id of the next TLS but i don't know when it actually arrived at
that LTS
Thank you

[sumo-user] How to relate phase numbers and edge ids?
Hello everyone, How can I make the relation between phase numbers and edgeIds from the TrafficLIght and the controlled lanes, edges, etc? Is there a generic way to do this?

[sumo-user] basic question
Hi, I am a new user of SUMO and looking for help in outputting edge-specific data. Namely aggregate speed on each edge. I am trying to enter the following line into my *.sumocfg file: but, it does not output an XML file like this. For that matter, I'm not entirely sure what I should put in for the edgeData id, either. The etnire output block in my config file looks like this: Can someone please help me to figure out the syntax to get the speed data I'd like? I DO manage to see the QueueData and summart-output. I do not see "vehcoclespeed" (bad typo, sorry) either. Any help is most appreciated!

[sumo-user] rerouteTraveltime Odd Behaviour
Hello, I’ve ran into an odd behaviour in regards to traci.vehicle.rerouteTraveltime(). Sometimes, the best time will produce a route with an absurdly long (as in it will be 100x more than expected kind of long) estimated travel time (using the current travel times of the edges in the route) - unusually, this is not actually the ‘best’ travel time possible, other routes are actually available which are a far better which aren’t picked up by rerouteTravelTime. Do you know why this may be? Have you come across this before? If so, is there a fix to this issue?

Re: [sumo-user] Question on Pedestrian detection
Dear Mr.Erdmann Thank you for your quick reply. I already checked it.. and I tried. It didn't work.. because of crossing index issues and network file. Anyway I will try again.

[sumo-user] Question on Pedestrian detection
Dear SUMO Users I have a question on pedestrian detection (Push-button in front of crossing). For my simulation, I want to change pedestrian signals based on detection of pedestrian in front of crossing. However, with induction loop (E1 detector), it is not possible because of detector characteristics (Size and detection info). Some pedestrians stop to cross and others keep walking to other directions, then E1 detector could detect both. So I am thinking that I may use Traci code (Person - getwaitingtime etc). I wonder if in SUMO, it is any way to detect pedestrian demand for crossing such as push-button in reality. I am looking forward to your reply. Thank you for your time in advance.

Re: [sumo-user] Fast Pedestrian Walks/Negative Time Loss
Hello, the problematic behavior is caused by an invalid pedestrian route. The edge sequence 633 -629 leads to junction 476 which is not connected with next route edge -813 This causes the person to walk contrary to the expected direction and thus reach the arrival position earlier than expected. In the latest development version of SUMO additional warnings have been implemented to make the faulty behavior more obvious. A possible fix would be to either use the sequence 633 -629 -629 -813 or 633 -813 The network itself is problematic insofer that it deviates from the two possible styles for pedestrian network modelling: 1) with crossings and walkingAreas. This makes it explicit where pedestrians may cross the road and is the recommended style for detailed pedestrian simulation ( http://sumo.dlr.de/wiki/Simulation/Pedestrians#Building_a_network_for_pedestrian_simulation ) 2) without crossing and walkingAreas but with sidewalks that have no connections. In this case, pedestrians will assume a fully connected topology at each intersection but their paths are not modelled (they "jump" across). This type of network is generated automatically by netconvert when not generating crossings or walkingareas. Note, that "jumping" potentially causes negative timeLoss in the current version but this will only be noticable if the dwadling option is disabled. In your case the network contains sidewalks that are connected but this forces awkward detours because there are no connections that allow changing the walking direction. regards, Jakob 2018-07-25 15:15 GMT+02:00 Albiston, Gregory 2012 (PGR) < gregory.albiston2...@my.ntu.ac.uk>: > Hello, > > > I have a scenario where there are numerous pedestrians undertaking walking > stages. > > Some of these stages are resulting in negative time losses meaning the > pedestrian is arriving faster than the maximum speed. > > All the vehicle stages have positive time losses. > > > Attached is an example scenario for one pedestrian which shows the issue. > The first and final stages are completed with a time loss of -79.75 and > -188.83.

Re: [sumo-user] Efficient way to count #vehicles within a distance of junction
