[sumo-user] The traffic simulation at the complex intersection
Dear all Sumo-user, My name is Bean and I am a lecturer at University of transport and communications in Vietnam, I am a new sumo-user. In recent days, I spend much time to research the methodologies of Sumo and how can it deal with my project named " The traffic simulation at the complex intersection" in Taiwan. And right now I need your help and support. *First of all, I use TraCI for my project. Unfortunately, I have already finished the "*...net.xml" file by NetEdit software. If I want to use TraCI and python code of TraCI, I have to finish a lot of files first, for example, the (...nod.xml, *.rou.xml, ..,.edg.xml). * *So how can I solve this problem?* The second question is *How I can use the NetEdit to draw the medium traffic where plant the trees, grass, flowers, etc... between two lanes?* Many thanks. ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/sumo-user
Re: [sumo-user] Gathering parking delays info from simulations - addidional question
Rerouting when the targeted parkingArea is full only happens when passing a rerouter with parkingAreaReroute definitions. Thus the routing device has no influence on this either before or after insertion. regards, Jakob 2018-06-14 15:39 GMT+02:00 Lara CODECA : > Additional question, and I hope that it's not too stupid. > > In my setup I have all the rerouters for the parkings in the same edge of > the parking lot. > Sometimes in the final route of the vehroute that edge is not present at > all. > You already told me that the change can happen in the rerouter edge or the > parking edge (that is > the same in my case), are there other cases? > > For example, what is going to happen if before the vehicle enter the > simulation the parking is > already full?

Re: [sumo-user] Prioritisation of public transport at traffic lights
Hello, there is no out-of-the box traffic light algorithm that does this so you need to use TraCI. The linked tutorial shows such a prioritization controller: http://sumo.dlr.de/wiki/Tutorials/TraCI4Traffic_Lights regards, Jakob 2018-06-21 14:06 GMT+02:00 florian preusse : > Dear Sumo-users, > > > I would like to know, if there is a way in Sumo to prioritise public > Transport at traffic lights.

[sumo-user] Netconvert changes
Dear users and developers, to improve the realism of the simulation when used with out-of-the-box settings we are going to change the default values of various options and parameters for our upcoming 1.0 release (see https://github.com/eclipse/sumo/issues/4235). In the development version we started with changing the default size and detail of intersections. Since this has wide-reaching effects, it may lead to unexpected changes when rebuilding simulation networks. If you are using the latest development version and require legacy behavior, you may just set the old parameter values: --default.junctions.size 5 --junctions.corner-detail 0 If you notice undesirable netconvert behavior, please let us know. regards, Jakob ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/sumo-user

[sumo-user] How to getParkingAreaStop
Dear All, via TraCI I'm trying to know if a vehicle has a stop planned in its route, and if so, I'm going to add it to the subscriptions to monitor it. I'm using traci.simulation.getLoadedIDList() at each step to have the list of vehicles, and I would like to have the setParkingAreaStop() counterpart in order to know if the vehicle has some stops planned. Is there a way to know this via TraCI? Thanks in advance, Lara Refs: http://www.sumo.dlr.de/daily/pydoc/traci._simulation.html#SimulationDomain-getLoadedIDList http://www.sumo.dlr.de/daily/pydoc/traci._vehicle.html#VehicleDomain-setParkingAreaStop -- Lara CODECA Postdoc Tel : 04.93.00.81.51 EURECOM Campus SophiaTech http://www.eurecom.fr/ ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/sumo-user
[sumo-user] tl actuated control with fixed cycle
Hello sumo users, I'm a new user and I would like some help on traffic lights actuated control. I would like to apply actuated control (phase call and gap time) while keeping cycle time fixed to maintain coordination on an artery. I'm trying to do this using TraCi python interface. Are there any examples or documentation that could help me?
