The first SUMO User ConferenceIntroduction

The first SUMO User Conference “SUMO2013” was attended by 30 participants from throughout Europe which presented three days of simulation results but also technical enhancements and new usage scenarios of the open source microscopic traffic simulation. The highlights were two keynote speakers, Christoph Sommer (Universitaet Innsbruck) and Kai Nagel (TU Berlin), which talked about the current developments in the simulation of vehicle communication, one of the main applications of SUMO, as well as experience with the development of MatSim. The program was rounded off by numerous discussions on the edge and a panel discussion, which will promote further exchanges among other simulation scenarios.

Conference Information

Traffic simulations are of immense importance for researchers as well as practitioners in the field of transportation. SUMO has been available since 2001 and provides a wide range of traffic planing and simulation applications. SUMO consists of a suite of tools covering road network imports and enrichment, demand generation and assignment and a state-of-the-art microscopic traffic simulation capable to simulate private and public transport modes, as well as person-based trip chains. Being open, SUMO is also ready to implement new behavioral models or to control the simulation remotely using various programming environments.

These and other features make SUMO one of the most used traffic simulations with a large and international user community. Further information about SUMO can be found at the project’s web pages located at http://sumo.sf.net.

The conference aims on exchanging experience in using SUMO, and presenting results or solutions obtained using the software. We expect a large variety of research topics and usage approaches. If you are doing a research project with SUMO and want to present your results please submit an abstract.

Some of this is interpretation of the input data. Make sure to use the recommended options: +https://sumo.dlr.de/docs/Networks/Import/OpenStreetMap.html#recommended_netconvert_options. If input data is lacking your best option may be heuristic generation: (tls.guess, https://sumo.dlr.de/docs/netconvert.html#tls_building) + +Q: 13:28:26 From John Pinder : i cant find the tools folder with osmWebWizard.py in, have i not installed it correctly? +A: if you downloaded the installer, check to target of the link in your start menu. If you downloaded the zip it should be in there. + +Q: 13:30:09 From Guang Wu To All Panelists : Can stop sign be created by osmWebWizard? It seems stop sign is not from auto-generated .xml files? +A: 13:30:45 From Michael Behrisch : No stop signs but the priorities of the junctions are usually correct +A: At the moment, no. The relevant information is currently not extracted from OSM. You can manually change the junction type to priority_stop though. + +Q: 13:30:49 From Mohit Garg To All Panelists : There are some other files I saw somewhere .emi.xml and poi.xml files. What are they for? +A: .poi.xml is the customary extension for points of interest which are loaded mostly for cosmetical purposes. .emi.xml is not a customary extensions and could be anything (i.e. user defined additional input files to declare outputs + +Q: 13:33:03 From John Pinder : where is the default install path in ubuntu? +A: 13:33:16 From Michael Behrisch : /usr/share/sumo + +Q: 13:34:15 From Ei Ei Mon To All Panelists : can we get the flow and route information instead of trip.xml after using osmwebwizard? +A: 13:34:54 From Michael Behrisch : Not directly but you can simply call duarouter for that.

Thank you for the nice introduction. We have been using SUMO for some years and we jumped into meso at the time it was introduced, being it a real experience. What would be the best way to interact with you in terms of getting advice, gathering suggestions, or doing evaluation? +A: 14:53:45 From Robert Hilbrich : @Eduardo: you can reach us on our regular support channels (sumo-user mailinglist, mattermost, twitter) where we provide free support; the German Aerospace Center is a choice for a more elaborate research collaboration and we have a spin-off - the co4e.com - for professional consultancy and support (and less research) + +Q: 14:59:38 From Eduardo Perez Guzman To All Panelists : Thanks a lot for the Information. And do you have any advice from your experience about getting traffic lights Information in Germany (Lichtsignalanlagen)? Is it something DLR makes use of? This turns to be a key point for large scale simulations like the ones we perform. +A: It's difficult and involves lots of handcrafting.

In mathematical models used? +A: Sumo uses car-following and lane-changing models whereas MATSim uses a coarser and faster queing model (very similar to SUMO-meso). MATSim also includes models for building a virtual population and their plans (whereas SUMO requires those plans as input) + +Q: Is it possible to draw the TAZ in different shapes (say I want to draw a TAZs based on neighborhoods) using the tool shown in the tutorial? +A: Arbitrary polygonal shapes can be drawn. TAZ can also be built based on shapes from OSM: https://sumo.dlr.de/docs/Tools/District.html#edgesindistrictspy + +Q: Do you plan to improve or update Traci? Currently, I am trying to integrate Sumo to Unity, and road construction was a bit hard. The shape list of a lane only gives information about the center line, but I needed end points of a lane in Unity. +A: TraCI is mainly for dynamic features. Lane geometry is static and tools/sumolib is the recommended library to retrieve this data. sumolib.geomhelper.move2side can be used to compute the outer boundar for a given lane center line. + +Q: Is it possible to automatically optimise traffic light signal plans. By changing green times and/or cycle times. By running multiple simulations and resulting into an optimum. Which is minimal traffic delay. +A: Sumo does not include tools for iterative optimization. Timing and offsets can be optimized for given traffic demand: https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#improving_generated_programs_with_knowledge_about_traffic_demand + +Q: I see you plan to couple SUMO with some pedestrian models. Which pedestrian models do you think are good candidates for this? +A: We plan to couple SUMO with JuPedSim which contains multiple models. Social Distance and Cellular automaton models could all be useful. Any kind of model as long as it's fast enough. + +Q: What is the most efficient way to estimate travel times for paths from SUMO simulation output? +A: edgeData-output with duarouter or tripinfo-output with vehicles that drove the desired paths + +Q: How can one associate trips generated from od2trips with passenger cars exhibiting varying behavior (e.g. in terms of car-following or lane changing)? +A: od2trips option --vtype TYPEID and then in sumo load an additional file that defines vTypeDistribution TYPEID (https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#vehicle_type_distributions) + +Q: Is there any weather information in sumo? +A: There is no direct support for wheather but sumo can associate arbitrary date with network edges using generic parameters (https://sumo.dlr.de/docs/Simulation/GenericParameters.html) and custom models can access these parameters. + +Q: Does SUMO support multi-cores cpu? how to set SUMO simulation setting in order to fully utilize the computer resources such as multi-core cpu or GPU? +A: Routing can be parallelized over multiple cpu cores with sumo option --device.rerouting.thread and duarouter option --routing-threads. SUMO also supports option --threads for multi-core simulation but the realized speed-up is currently low. GPUs are not supported. + +Q: About TAZ: Is it possible to only allow specific edges to be a origin/destination edge in a TAZ? +A: Yes. gridDistrict.y and edgesInDistrict.py support option --vclass. filterDistrict.py also filters and existing TAZ with option --vclass + +Q: By any chance, are you aware any study using SUMO for simulating logistics process, e.g., in container terminals (or production systems in factory)?

See https://sumo.dlr.de/docs/sumo-gui.html#investigating_internal_edges_and_lanes + +Q: What are the main uses of SUMO for V2X? +A: mobility model for communication simulation, cooperative behavior (i.e. platooning, smart traffic lights) + +Q: Can you briefly describe how the Python packages work? Is it the recommended way to start and run simulations from Python? +A: Many python tools are stand-alone. tools/sumolib is for writing own tools (i.e. analyze networks), tools/traci is for coupling own code to a simulation (which can be started with traci.start). Normally sumo is started from the command line, batch files etc. + +Q: There are several car-following-models, do you know if they give results comparable to the one used by SUMO? +A: All model behave differently. The same model implemented in different simulations should mostly work the same but there are difference in situations that are not fully discribed by the model (i.e. +how to stop at intersections). + +Q: Is there a workaround to show WMS layers as background map in SUMO-GUI? or such feacture needs to be carefully developed (hopefully for future realeses)? +A: SUMO only supports backgrounds via raster images. Those can be imported from WMS via tileGet.py: https://sumo.dlr.de/docs/Tools/Misc.html#tilegetpy + +Q: Is it planned to implement another lane change model, for example MOBIL? +A: Not directly but the API is module and pull-request are very welcome. The SUMO-team may be able to give support to anyone willing to do so. + +Q: Topic train/bus tls request: Is it possible to create a traffic light program with a (preferred) bus/train request without TraCI? +A: Actuated traffic lights support custom detectors and those can filter by vType. Together with a branching program this could make the traffic light adapt to public transport: +https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#dynamic_phase_selection_phase_skipping + +Q: Is it possible to define a minGap when a car passenger follows a heavy truck and a minGap when following an ordinary vehicle? +A: No by default but it's possible via TraCI or custom carFollowingModels + +Q: Is there a way to have a command-line SUMO as a "server" and connect something like SUMO-GUI to it? E.g. running a SUMO in docker and check how the simulation runs? +A: Yes. See https://sumo.dlr.de/docs/Tools/Misc.html#statereplaypy. Additional features are planned. + +Q: Is it possible to embed rerouters to divert pedestrian traffic temporarily? +A: No. Rerouting pedestrians only works via TraCI at the moment. + +Q: I find sometimes emergency vehicle (has been equipped with bluelight device and permitted to violate red light through setting jmDriveAfterRedTime) does not change lane to pass intersection during red light, is there any possible reason for it and how to solve it? +A: Possible bug, please send in minimum example scenario. + +Q: The number of teleports increased considerably when we use calibration ? Do you have any idea about that? +A: If calibration increases traffic, any problems with the network/infrastructure model likely show up as jamming/teleports. + +Q: When SUMO automatically generates traffic light sequences, does it estimate flow rates? +A: No. Flow can be incorporated into signal plans via extra tools: https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#improving_generated_programs_with_knowledge_about_traffic_demand + +Q: Is this session of the tutorial being recorded? +A: Q&A is not recorded + +Q: Have you mapped the historical data based on GTFS-R data? +A: No. Import into static scenarios should work. + +Q: I have a very little experience about this, but, are there many implementations of SUMO connected with real-time data from Waze and tomtom (car flow applications)? I would appreciate if you have any links to share as well. Thank you. +A: We are not aware of this kind of coupling. + +Q: Is there any efficient way to insert a new phase during a cycle? Now I implement it by switching to a new program and switch back to the original +A: For various options see https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#controlling_traffic_lights_via_traci + +Q: I have noticed that when the vehicles change lanes, they change at 90 degrees in the adjacent lane. Is it possible that they line up over a greater distance like in real life? +A. See https://sumo.dlr.de/docs/Simulation/SublaneModel.html + +Q: Does SUMO used for only virtual scenarios which are similar to reality or do we have implementation in the real world? +A: All scenarios are virtual in a sense but some there are some projects with tight coupling to real-time data. (https://elib.dlr.de/105545/1/HEUREKA%2717_VITAL_online.pdf) + +Q: Can SUMO simulate electric vehicles, and charging infrastructure?

I use the plot_net_dump.py. However, is there another way to get a better resolution emission map for a large scale network? +A: You can either increase the spatial resolution by splitting up your network +into shorter edges (netconvert --geometry.max-segment-length 100 +--geometry.split) or perform your own aggregation based on raw vehicle +emission data (--emission-output) + +**************** + +Q: Presently to launch SUMO from a third-party simulation software (e.g OMNeT++) both softwares must be on the same machine or on a network thru a shared folder...do you plan to to make it possible thru a client-server scheme ? +A: TraCI already supports connection to a running sumo simulation on another +machine. + +**************** + +Q: We have been looking to model real time operation of ambulances using Sumo taking real-time incidents. Is there any available library to model emergency vehicles? The challenge is allowing vehicles to adopt contra-flow as well as disregard red lights and other vehicles to give way to the emergency vehicles +A: Yes. See https://sumo.dlr.de/docs/Simulation/Emergency.html + +**************** + +Q: Are you planning to collaborate with the OGC community to consider cityGML (https://www.ogc.org/standards/citygml) for network imports or make 3D visualization in Cesium coupled with Unreal (is it OGC vs. OSG? :D) +A: We were not aware of the OGC community but are open for ideas. Feel free to +open an issue on github and lay out your idea + +**************** + +Q: Can you also add weather information in sumo and see how it will affect the traffic? +A: We are in the process on merging the road friction feature and one +carFollowmodel that considers this value. This will permit to model a range of +weather related influences on traffic. + +**************** + +Q: Is SUMO not using TRACI for generating the Simulation at the first time? What is rerouting? +A: No. TraCI is and advanced feature for coupling SUMO to another process. To +learn more about rerouting, see https://sumo.dlr.de/docs/Simulation/Routing.html + +**************** + +Q: To what extend is it possible to simulate shared spaces? or the interaction between cars and pedestrians? can pedestrians walk in sub-lane? +A: Cars and pedestrians can move on the same lanes as well as through shared +intersections. Pedestrians move freely within these spaces while avoidig the +cars. Likewise, cars "see" the pedestrians and avoid them. + +**************** + +Q: Are there any SUMO community groups/forums or mailing groups? +A: Yes. See https://www.eclipse.org/sumo/contact/ + +**************** + +Q: We use TraCI's openGap() function to control a platoon of vehicles, but sometimes instead of closing up a vehicle, it makes it slow down. Do you have any idea what may be the problem here? (Warning states tau cannot be smaller than the original, but I am sure, we have not reduced the tau) +A: This could be a bug in the openGap function. Please open up a ticket on +github and provide all input files for reproducing the problem. + +**************** + +Q: Is it possible to make Calibrators sense the few edges (meters) upstream in order to have an approximate picture of traffic volume that will pass on it in the current calibrator interval? + To be able to generate, let's say, an equal amount of vehicles (or some distribution) during the calibration interval. So far, it often happened that Calibrator waits until the end of the interval and then generates a higher amount of vehicles forming the platoon.

We intend to solve it by increasing +calibrator flexibility: https://github.com/eclipse/sumo/issues/10698 + +**************** + +Q: My research in emergency vehicle prioritizes system that needs input from google maps or any mapping platform. How do I integrate the mapping platform to SUMO +A: There are a range of tools for using geo-referenced data with SUMO. See https://sumo.dlr.de/docs/Geo-Coordinates.html + +**************** + +Q: Is there a way to model or apply car taffic noise file in SUMO thru in a noise reduction project ? +A: SUMO has a noise emission model that can either provide aggregated data (for +edges or trips) or raw-data (--emission-output) + +**************** + +Q: Does the integration method have an impact on traffic flow regarding the use of Cars following the model? E.g, can ballistic integration be used with EIDM? +A: Yes and Yes. + +**************** + +Q: Is it possible to make TL states that apply only to certain traffic modes? In the UK, we have signals which give a green light to cyclists only for a few seconds before the full green (in mixed-traffic lanes, not just for cycle lanes) +A: Not directly: Each lane-to-lane connection has exactly one signal state. A +workaround is to distinguish the bicycle connection either by adding a short +bicycle lane before or after the junction. + +**************** + +Q: Where are the laneid, junction ids given (any script)? +A: The lane ids are computed based on the edge id (by adding _INDEX). Edge and +junction ids can be set by the user. When importing data (i.e. from OSM) the +original ids are kept as closely as possible.

Currently, I am trying to integrate Sumo to Unity, and road construction was a bit hard. The shape list of a lane only gives information about the center line, but I needed end points of a lane in Unity. +A: TraCI is mainly for dynamic features. Lane geometry is static and tools/sumolib is the recommended library to retrieve this data. sumolib.geomhelper.move2side can be used to compute the outer boundar for a given lane center line. + +Q: Is it possible to automatically optimise traffic light signal plans. By changing green times and/or cycle times. By running multiple simulations and resulting into an optimum. Which is minimal traffic delay. +A: Sumo does not include tools for iterative optimization. Timing and offsets can be optimized for given traffic demand: https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#improving_generated_programs_with_knowledge_about_traffic_demand + +Q: I see you plan to couple SUMO with some pedestrian models. Which pedestrian models do you think are good candidates for this? +A: We plan to couple SUMO with JuPedSim which contains multiple models. Social Distance and Cellular automaton models could all be useful. Any kind of model as long as it's fast enough. + +Q: What is the most efficient way to estimate travel times for paths from SUMO simulation output? +A: edgeData-output with duarouter or tripinfo-output with vehicles that drove the desired paths + +Q: How can one associate trips generated from od2trips with passenger cars exhibiting varying behavior (e.g. in terms of car-following or lane changing)? +A: od2trips option --vtype TYPEID and then in sumo load an additional file that defines vTypeDistribution TYPEID (https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#vehicle_type_distributions) + +Q: Is there any weather information in sumo? +A: There is no direct support for wheather but sumo can associate arbitrary date with network edges using generic parameters (https://sumo.dlr.de/docs/Simulation/GenericParameters.html) and custom models can access these parameters. + +Q: Does SUMO support multi-cores cpu? how to set SUMO simulation setting in order to fully utilize the computer resources such as multi-core cpu or GPU? +A: Routing can be parallelized over multiple cpu cores with sumo option --device.rerouting.thread and duarouter option --routing-threads. SUMO also supports option --threads for multi-core simulation but the realized speed-up is currently low. GPUs are not supported. + +Q: About TAZ: Is it possible to only allow specific edges to be a origin/destination edge in a TAZ? +A: Yes. gridDistrict.y and edgesInDistrict.py support option --vclass. filterDistrict.py also filters and existing TAZ with option --vclass + +Q: By any chance, are you aware any study using SUMO for simulating logistics process, e.g., in container terminals (or production systems in factory)?

Is it the recommended way to start and run simulations from Python? +A: Many python tools are stand-alone. tools/sumolib is for writing own tools (i.e. analyze networks), tools/traci is for coupling own code to a simulation (which can be started with traci.start). Normally sumo is started from the command line, batch files etc. + +Q: There are several car-following-models, do you know if they give results comparable to the one used by SUMO? +A: All model behave differently. The same model implemented in different simulations should mostly work the same but there are difference in situations that are not fully discribed by the model (i.e. +how to stop at intersections). + +Q: Is there a workaround to show WMS layers as background map in SUMO-GUI? or such feacture needs to be carefully developed (hopefully for future realeses)? +A: SUMO only supports backgrounds via raster images.
