[sumo-user] vehicle postion in sumo
HI, I have a query regarding vehicles' position in sumo. Can we have multiple vehicles at the same position and lane in sumo? We are seeing pos as 7.80 and speed 0.00 for 3 vehicles at some timestep and wondering why they would get the same position. We are using the following flags Thanks, Mahima ___ sumo-user mailing list sumo-user@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user
[sumo-user] create lcModel
Hi, I have a query regarding creating lcModel for a vehicle. At what timestep, does the lcmodel created for each vehicle? Does it depend on the loading of routes? I can see it is created much before the depart time of a vehicle. How can I control it?

[sumo-user] LCA_TRACI
HI, I have a question regarding LCA_TRACI. When would this request be raised? I ran my parallel application which runs on top of sumo using libsumo, at a timestep vehicle shows stateRight value as "2048" On the other hand, when I run the same traffic and network using sumo command, I can see the stateRight value at the same timestep to be "2136". Why TRACI request bit is 1 here? Can we turn off TRACI requests? When we use libsumo, TRACI lane change requests are still generated?

Re: [sumo-user] vehicle set speed issue
Thanks for your reply. No, even setPreviousSpeed is not updating the speed. I think this is because myState.mySpeed is getting updated only in executeMove() and there is no other API which updates myState.mySpeed including step().

Re: [sumo-user] vehicle set speed issue
Hi Jakob, I guess this is the issue related to excuteMove(). If we call executeMove(), then we move the vehicle and update the speed of the vehicle after this using setSpeedMode(veh, 32) and slowDown() and we finally call step(). Here, the speedTimeline is not getting updated to myState.mySpeed for the current step. This is the reason that getSpeed() is giving old speed before calling slowDown. On the older branch when executeMove() was not there...I was able to change speed in the current step.

[sumo-user] vehicle set speed issue
Hi, I am adding a vehicle on a lane with max depart speed (max speed of this lane is 16.67). Now, in the same timestep I am moving this vehicle to the next lane (max speed of this lane is 27.78). I want to change the speed of this vehicle to 22.27. But, when I check the fcd file, the position and lane changes as per the moveTo but speed remains 16.67 only. Please suggest why the speed is not going beyond the depart speed in this timestep and how I can achieve this.

Re: [sumo-user] vehicle parameters for the current step
Yes, I have checked sigma is 0. Do we have a similar function in libsumo like processLinkApproaches() that can give me vSafe? Just found out that to calculate speed for the next step, sumo calculates using processLinkApproaches() and NOT as follows. double vthis=LastTimestepSpeed+ACCEL2SPEED(LastTimestepAcceleration); Thanks for your help.

Re: [sumo-user] vehicle parameters for the current step
Hi, We have developed a parallel framework over SUMO. When I am copying vehicles from one partition to another. With the vehicles I am also copying the following lane change parameters. I am keeping sigma 0, --random false and same seed value for all the partitions and sequential SUMO. "laneChangeModel.speedGainProbabilityRight" "laneChangeModel.keepRightProbability" "laneChangeModel.lookAheadSpeed" After adding vehicles in the next partition, I am also moving them for the desired position in the current step and setting speed for the current step. i am calculating the current step speed as follows: double vthis=LastTimestepSpeed+ACCEL2SPEED(LastTimestepAcceleration); Or if the vehicle has a Leader...then with the follow speed. But if I compare travel time of this parallel framework with sequential SUMO, I am getting an accuracy error. I have found that patchSpeedBeforeLC is calculating some different speed which is causing randomness. vDawdle = MAX2(vMin, dawdle2(vMax, sigma, veh->getRNG())); This randomness calculation should be off when we use --random false.

Re: [sumo-user] vehicle parameters for the current step
Thanks for your reply. Yes, sigma is already set as 0. The only difference I can see is the stop speed (getStopSpeed) is different. How can I set the stop speed of a vehicle? Is it by using libsumo::Vehicle::setStopParameter? But then I need to define the stop first...correct? Thanks.

I read speed, accel and position using these commands which give values of the last timestep. libsumo::Vehicle::getLanePosition(veh)); libsumo::Vehicle::getSpeed(veh)); libsumo::Vehicle::getAcceleration(veh) And then I use the following commands in the current timestep so that I get the desired position and speed in the next timestep. libsumo::Vehicle::setPreviousSpeed(veh, speed, accel); libsumo::Vehicle::moveTo(veh, cmd.lane_id(), lane_pos); Then, I check the leader double frontGapNeeded = libsumo::Vehicle::getSecureGap(veh, speed, libsumo::Vehicle::getSpeed(leader.first), libsumo::Vehicle::getDecel(leader.first)); double followSpeed=libsumo::Vehicle::getFollowSpeed(veh, speed, frontGapNeeded, libsumo::Vehicle::getSpeed(leader.first), libsumo::Vehicle::getDecel(leader.first), leader.first); double frontMax = frontGapNeeded + (-leader.second); double new_speed = std::min(speed, followSpeed); double pos = std::min(lane_pos, frontMax); Then, i set the vehicle speed as per the leader. libsumo::Vehicle::slowDown(veh, followSpeed, 0); But, I am not getting desired results.

[sumo-user] question regarding sumo lane change
Hi, I can see that in the current sumo implementation, vehicle lane change is dependent upon the whole route visibility of this vehicle. Is there a way so that the vehicle lane change decision takes place only as per the next edge visibility and not the whole route. For instance, if I run the same vehicle with a shorter route and a longer route, the lane change decisions will be different. Can we change this implementation in sumo code? Can you please help me with this? Thanks, Mahima ___ sumo-user mailing list sumo-user@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user

Re: [sumo-user] libsumo GUI
bool
GUI::load(const std::vector& /* cmd */) {
if (myWindow != nullptr) {
WRITE_ERROR("libsumo.load is not implemented for the GUI.");
return true;
}
return false;
}
How "Simulation::load" will work for GUI? I guess we need to use
Simulation::start. Do we need to set env "LIBSUMO_GUI"?
Please helpI need it urgently.

I can use sumo-gui in the same repository. But, only
libsumo::Simulation::load and libsumo::Simulation::step is not launching

Re: [sumo-user] vehicle parameters for the current step
When I am copying a vehicle from one partition to the other on the same lane and position as it was on the previous partition, but in the current timestep if there was a lane change decision in the previous partition..which lane change API or flag will give me the same lane change decision in the master partition.

Re: [sumo-user] Vehicle lane change state
Thanks, for your reply. I am using the default car following and lane change models. Actually, I am working on a parallel version of sumo and I am moving vehicles from one partition to another. With the vehicle I also want to copy the lanechange state and value of keepRightProbability. So that my vehicle shows the same lane change behavior as it was on the previous partition. Currently, when I am just moving the vehicle without copying the lanechange state it is showing sudden lane change to right at the red traffic light. On the other hand, if run on sumo it stays on the leftmost lane for all these timesteps. I read the following and thought of copying the lanechangestate as well. *In the current lane-changing model, each vehicle maintains a variable keepRightProbability which is decremented over time and triggers a lane change to the right once a lower threshold value is exceeded (negative values are used in allusion to the variable speedGainProbability).* Please suggest how I can set the same lane change bitmask.

Hi Jakob,
Thanks for the reply.
On calling this so as to close the lane,
libsumo::Edge::setDisallowedVehicleClasses("79324",{"all"});
I get a segmentation fault with this error.what(): Vehicle '11'
has no valid route. No connection between edge '179325' and edge '79324'.
I was waiting that the vehicle should reroute when rerouting probability is
set to 1.
Why it is still searching for this edge?

[sumo-user] lane close reroute
Hi, I have a query - when we are running a simulation on sumo-gui and we want to close the edge by right-clicking on the edge. Where does the new network is saved? Which parameters are passed from the user interface to sumo?

[sumo-user] Reroute
Hi, I have a query. I am running static flow in sumo and rerouting is off (device.rerouting.period value is not set). Still on running 1 vehicle on sumo, I can see rerouteno=1 in the trip statistic. Why rerouting will happen when there is no congestion? http://www.w3.org/2001/XMLSchema-instance; xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/tripinfo_file.xsd;> Thanks, Mahima ___ sumo-user mailing list sumo-user@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user
Re: [sumo-user] routing algorithm
Hi Jakob, Thanks for the reply. So, it means if we are creating initial route file with turning ratio (20, 70, 30) using JTRrouter for a simulation and rerouting period is SET in the SUMO configuration file, the periodic rerouting will be automatically done by SUMO using the default GAWRON algorithm and not as per the turn ratios defined in the routing file.

[sumo-user] routing algorithm
Hi, I want to know which is the fastest (meaning least average mean trip time of vehicles) re-routing algorithm in the congestion scenarios. I tried running some scenarios using SUMO and found jtrrouter to be the fastest. Please respond.

[sumo-user] libsumo simulation start
Hi, I want to use the following command to start a simulation. "libsumo::Simulation::start" But this gives an error. Any idea what is the alternative way to start the simulation?

[sumo-user] Sumo traffic simulation
Hi everyone, I have a query regarding SUMO libsumo interface. Do we have any way to read the arrival position and arrival lane index using (libsumo::Vehicle::)? I can see libsumo::Vehicle::getTypeID and libsumo::Vehicle::getLaneIndex getLanePosition for departure lane. But how to read the arrival position? Please reply ASAP.
