Re: [sumo-user] [SUMO-USER] Can I create congestion in SUMO?
Yes, you can. But you need to create a bottleneck (e.g. accident, traffic signal, lane drop). The easiest is probably a traffic light or a lane drop.

[sumo-user] Make a vehicle stop to take a passenger
Hi, I have to implement a stop on demand system. I created the bus stops and a ring route that the busses follow. When a pedestrian is created, it is supposed to walk to the first stop with a walking stage, then with a driving stage take the bus, at the same time traci sets the stop using the command setBusStop and stopping a determined bus. The busses are introduced with traci, operate the same line that the pedestrian calls. I receive this warning: Warning: Not using public transport line 'MINDShuttles' for routing persons. It has less than two usable stops. And my pedestrian just disappears as soon as he reaches the stop. What did I do wrong? how can I make the vehicle stop and take the pedestrian? When I append the driving stage I do not specify from which station to start, I assumed the pedestrian should start from the bus station where he is at, as a destination of the preceeding walking stage, am I right?

Re: [sumo-user] Modifying the SUMO network at runtime
Hi Jakob, I have implemented your suggestion to use SUMO's save and reload process to account for network modifications at runtime. It mostly works, but I'm seeing issues when I add new edges and lanes into the network in between the save and reload. In that case, my vehicles don't restart on the lanes I expect them to. (For a little background, I have built a process to create new edges and lanes inside water polygons, so I can simulate boats moving around in a lake or ocean without relying on waterways from OSM. So I import an OSM map to create an initial network, launch SUMO on it, then kick off my water-network builder which process XML node and edge files, which I merge into the original network using netconvert. This process adds new edges and lanes based on the water mesh it built. I hope to use the save and reload to pickup these new water edges without completely restarting my simulation). When I look in the save-state XML file, SUMO is saving out actual lane IDs, but when I look at the reload code (MSStateHandler.cpp, method myStartElement, case SUMO_TAG_LANE), it seems to rely on the index of the edges and lanes being the same as they were when the file was written. If any edges or lanes get added to the network after save, things get out of order. Would it be possible to use the edge and lane IDs directly to look up those items instead of relying on indexes? Then the reload process would be more resilient and could better handle added/reordered/deleted edges and lanes. I'm about to experiment with that change but wanted to see if there were any gotchas.

Adding nodes and edges at runtime would be quite difficult since you would have to replicate all the procesing steps of netconvert (e.g. to compute intersection rules) as wells as all the steps that are done by the simulation when loading a network (some of them interdependent and to be done in the right order). Modifying elevation at runtime would probable be doable since this part of the network data has no interdependencies with other structures and you could borrow code from traci.polygon.setShape. An alternative might be to save the simulation state (--save-state) and then restart the simulation with a modified but compatible network and the saved state. regards, Jakob Am Di., 5.

Re: [sumo-user] SUMO 1.2.0 released
Dear macOS users, the homebrew formula has just been accordingly updated and bottles are available for both High Sierra and Mojave. For more information, see https://sumo.dlr.de/wiki/Installing/MacOS_Build_w_Homebrew Have fun! Best regards, Matthias -Original Message- From: sumo-user-boun...@eclipse.org [mailto:sumo-user-boun...@eclipse.org] On Behalf Of Michael Behrisch Sent: Dienstag, 16. April 2019 10:20 To: SUMO User; SUMO Announce Subject: [sumo-user] SUMO 1.2.0 released Dear friends and users, we are happy to announce the release of SUMO version 1.2.0. The download links are at http://sumo.dlr.de/wiki/Download This release brings a brand new Netedit mode to edit vehicles, trips and flows! We are looking forward to your feedback to shape further development of this feature. This release also contains many improvements for intermodal simulation in regard to dynamics, visualization and data output. There are many more new features and fixes in this release and the most important ones are listed below. For a full list of changes, as always see http://sumo.dlr.de/wiki/ChangeLog We're looking forward to meeting you soon at the SUMO user conference (http://sumo.dlr.de/2019). ===Enhancements=== NETEDIT - Added new mode to create and edit traffic demand (vehicles, trips, flows, vTypes, routes, stops) - Major improvement in rendering speed Simulation - added new input element - improvements to parkingArea simulation (cooperation, adapting riding person plans) - edgeData-output now supports attribute detectPersons="walk" which can be used to record pedestrian traffic instead of vehicular traffic. - Person rides now allow the special value 'ANY' for the 'lines' attribute. When this is set, persons may enter any vehicle that will stop at the destination 'busStop' of the ride. - Added controllability of reaction time (actionStepLength) to DriverState Model. - various railway simulation improvements (reversing direction, signal operation, visualization) - Traffic light phases now support the optional attribute 'name'. This attribute can be set and retrieved via TraCI and makes it easier to establish the correspondence between phase indexing in SUMO and phase descriptions used by other traffic engineering methods - improved default parameters for simulation routing to avoid biases from traffic light cycles SUMO-GUI - Major improvement in rendering speed - Can now load edge-data for visualization of arbitrary attributes with time-varying edge colors - Improvement to visualization of riding and waiting persons - Can now locate objects by their name (streetname or generic parameter key="name"). - Vehicles with guiShape 'truck/trailer' and 'truck/semitrailer' now bend when cornering. NETCONVERT - Improved junction joining heuristic to prevent superfluous joins. - OpenDRIVE Road_Objects can now be imported and also written to OpenDRIVE output - Various improvements to the generation of traffic light plans. DUAROUTER - Added option --write-trips.geo to write trips with attributes 'fromLonLat, toLonLat' instead of 'from' and 'to' - Reading trips with attributes 'fromLonLat, toLonLat, fromXY, toXY, viaLonLat, viaXY' is now supported. - Added option --weights.random-factor to randomize routing results with bounded deviation from optimality (vehicles and persons). Miscelaneous - The option --help now supports filtering by topic (e.g. '--help input') - Added Tutorial for Manhattan Mobility ===Bugfixes=== Simulation - Various model fixes that were causing emergency deceleration - Various fixes to routing (vehicular and intermodal) - Various fixed for actuated TLS - Various fixes to railway simulation TraCI - fixed crashes when calling moveToXY - Various TraaS fixes (regressions from 1.0) - restored python3 support for osmWebWizard.py (regression in 1.1.0) Other - Joining junctions now preserves the prior connection topology. - Many fixes to netdiff.py and to applying netdiff-generated patches Have fun with the new release, Yun-Pang, Laura, Leo, Pablo, Jakob, Robert, Melanie, Johannes, Matthias and Michael ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user ___ sumo-user mailing list sumo-user@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user

[sumo-user] Teleports only in case of "Wrong Lane"
Dear Community, I'm trying to solve a teleportation issue.. I have a simulation with 50K vehicles and people. It represent a morning rush-hour, so there a re different levels of congestion. Thanks to the option I can avoid teleportation on collision. Unfortunately I still have many of them: Teleports: 1155 (Jam: 521, Yield: 452, Wrong Lane: 182) >From what I understood from the FAQ, "Jam" and "Yield" are related to >congestion, and only "Wrong Lane" is actually required to avoid gridlocks on >intersections and roundabouts. Is there a way, varying some parameters, to allow teleportations only for "Wrong Lane"? I tried to play with "ignore-junction-blocker", "time-to-teleport", "max-depart-delay", "time-to-impatience" but it didn't work. Any ideas? Is it even possible? All the Best!

[sumo-user] traci and libsumo
Hello community, I wrote a python library that uses traci to implement a parking monitoring system (https://github.com/lcodeca/PyPML). I'm trying to find a way to use libsumo (or even better both, leaving the choice to the user) in order to improve the performances. Unfortunately, although is written in https://sumo.dlr.de/wiki/Libsumo that "Existing traci scripts can mostly be reused by calling import libsumo as traci", it's not true for me. I always used http://sumo.sourceforge.net/pydoc/traci.html to use traci, but this is not true for libsumo. I'm trying to use https://sumo.dlr.de/daily/doxygen/d8/d1c/class_tra_c_i_a_p_i.html because it's written "C++ interface based on static functions and a few simple wrapper classes", but I don't understand how to apply this documentation to a python3 style use of traci. I cannot find any explicit example in the wiki that gives me the hint on how to do this. I would love if someone could point me in the right direction.. All the Best!

[sumo-user] lateral acceleration
Hello Sumo Community, i have another question about the lateral acceleration. I know that by using the standard lane change model (Krauß), vehicle would always drive in lane middle. In case of turning the junction how can we get the lateral acceleration? Could we help me to understanding if this variable is somehow retrievable ?
