Re: [sumo-user] Speed-Exponent and Speed

The edge probability (for depart and arrivel) is multiplied by edgeSpeed^speedExponent. The default exponent is 0 so speed does not influence probability. with an exponent of 1, edges with twice the speed are twice as likely to be sampled. regards, Jakob Am Sa., 17. Nov. 2018 um 15:03 Uhr

Re: [sumo-user] * is not downstream the current route. traci.vehicle.setBusStop problem

Then the error message is correct in stating that "the stop is not downstream the current route". At this point you could either use a different stop or compute a route the cycles back to the start of the stop edge. For the latter case it should be sufficient to call vehicle.setVia(vehID,

Re: [sumo-user] * is not downstream the current route. traci.vehicle.setBusStop problem

Hello, Potentially the vehicle is already past the stop position? On what edge and position is the vehicle when sending the setBusStop command? If the vehicle is upstream of the stop, please send in additional information as described here:

Re: [sumo-user] Emission Output Timer

Hello, patching sumo is probably the easiest solution for your problem. Put your check into the file microsim/output/MSEmissionExport.cpp Alternatively, you could write the file to a socket and filter the data with another script before writing it to disk (

Re: [sumo-user] Adding penalties to current travel times.

The travel_time * penalty approach you describe is the most flexible and general approach. You could achieve a similar effect (automatically updated travel times, some customization via TraCI) with device.rerouting. http://sumo.dlr.de/wiki/Demand/Automatic_Routing regards, Jakob 2017-10-03 18:36

[sumo-user] 0.31.0 Bug notification

Dear users, Please note that a bug was introduced in Netedit version 0.31.0 that appears when saving networks which contain pedestrian crossings controlled by a traffic light (http://sumo.dlr.de/trac.wsgi/ticket/3472). It causes crossing to be uncontrolled. If you use Netedit to create pedestrian

Re: [sumo-user] Simulation Step TraCI call at time 0

Hello, when you take a look at the gui, you will find that the first call of simulationStep(0) advances the simulation to the end of step 0 (with vehicles departing at 0 already being inserted). Only the command simulation.getCurrentTime() already shows you 0.5 because all further traci calls will

Re: [sumo-user] Vehicle Intersection speeds

Hello, this is not yet supported in 0.31.0. However, If you use the latest development version (26919) you can set the speed attribute for connections (via .con.xml input) or netedit. http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version regards, Jakob 2017-09-22 12:02 GMT+02:00

Re: [sumo-user] Needing more information for platooning model

Hello, are you trying to implement a new model within sumo (C++) or are you trying to control the simulation via TraCI? In either case, the acceleration is implied in the change of speed from one step to the next. Within sumo you can call MSVehicle::getAcceleration() and from TraCI you need to

Re: [sumo-user] Vehicle gets routed through off-line station!?

Hello, edge priority is not taken into account for routing purposes. Neither is the number of junctions (or rather not in the correct way). The speed should take effect but you may be suffering from a known issues of junction distances being ignored and thus getting wrong distance estimates:

Re: [sumo-user] How do I get the time duration of green traffic light on a particular edge via traci4matlab?

First you need to determine the traffic-light index which corresponds to that edge (or rather to the lane-to-lane connections from that edge because each connection has it's own index). This is done by calling the function trafficlights.getControlledLinks. Then you can retrieve the state with

Re: [sumo-user] How are position and velocity computed when turning left/right at intersections?

Hello, by default, vehicles drive on so-called "internal edges" while passing an intersection. They follow the car follow model just as on normal edges/lanes. You can see these edges when you disable the option "draw junction shape" in the gui visualisation settings. Only if you have built your

Re: [sumo-user] How to convert junction to edge?

Hello, the small dark red dots are geometry points within an edge. They can be used to model curves without changing the edge id. Whenever the number of lanes changes or there is an intersection of 3 or more roads, all edges must have a unique id. In the norther intersection of your screen shot,
