| Re: [sumo-dev] Regrading Retrieval of vtype parameter using traci |
Thank you for your kind response.1. I have implemented the first option successfully for different vtypes.2. By Traci I used the following code. It is working successfully for a single vehicle and will work for multiple vehicles.If the number of vehicles increases and we want to check for each vehicle, then this code will have a lot of redundancy.Can you suggest me some changes so that I will be able to improve the code?def run():
# intialisation of variable
steps = 0
edge_id ="e0"
while steps < 3000:
traci.simulationStep()
#to get the edge id
edge_id0 = traci.vehicle.getRoadID("0")
edge_id1 = traci.vehicle.getRoadID("1")
#if the edge id is e1 then change vtype to d
if(edge_id0 == "e1"):
traci.vehicle.setType("0", "d")
if(edge_id1 == "e1"):
traci.vehicle.setType("0", "d")
#if the edge id is e1 then change vtype to c
if(edge_id0 == "e2"):
traci.vehicle.setType("0", "c")
if(edge_id1 == "e2"):
traci.vehicle.setType("0", "c")
steps+=1
traci.close()Thanks and RegardsShantanu PhanseDA-IICT, India_______________________________________________On Sat, May 8, 2021 at 12:10 AM Jakob Erdmann <namdre.sumo@xxxxxxxxx> wrote:There are several options for changing parameters based on location:- exchange the vehicle type with another vehicle type based on pre-defined xml input: https://sumo.dlr.de/docs/Simulation/Calibrator.html#calibrating_vehicle_types- monitor the vehicle location with traci and then use traci functions to change the type based on the current vehicle edge- define custom parameters for the edges (i.e. in netedit) and then use those parameters within your custom car following model to modify its own parameters based on the current edgeregards,Jakob_______________________________________________Am Fr., 7.

Can we have different values of the user-defined car following model parameters "I", "d" for different edges of a road network?eg. We have a road network of edges (e1---e2---e3) and say edge 1 has value i = 2, d = 10, and edge 2 has value i = 5, d = 40 in the same road network.Thanks and regardsShantanu PhanseDA-IICT, India_______________________________________________On Thu, Apr 22, 2021 at 2:03 PM Jakob Erdmann <namdre.sumo@xxxxxxxxx> wrote:_______________________________________________Am Do., 22.

I there any other way I can manipulate my user-defined parameters 'i' and 'd' while the simulator is running._______________________________________________On Thu, Apr 1, 2021 at 4:51 PM <Maria.Armellini@xxxxxx> wrote:_______________________________________________Hi Shantanu,
I have tried it myself and saw that when you use .setParameter a new parameter is created. For example, when you call traci.vehicletype.setParameter("c", "maxSpeed", '4.00'), you don’t change the maximum speed parameter, but a new parameter “param:maxSpeed” is created with that value (see picture). If you want to change the maximum speed, you can use .setMaxSpeed(). See VehicleType_Value_Retrieval and VehicleType_State.
As for the “i” and “d” parameters of your CF model, I think this is still under development, see GitHub-Issue.

Betreff: [sumo-dev] Regrading Retrieval of vtype parameter using traci
Hello,
I have created a new car-following model in SUMO for practice.
rou.xml has vtype attribute as follows
<vType id = "c" departLane = "best" maxSpeed = "16.67" carFollowModel="W" d = "30" i = "12"/>
------------------------------------------------------------------------------------------------
I aim to change the vtype parameters of maxSpeed, i, d using traci.
The snippet of the code I am using is as follows
def run():
steps = 0
while steps < 1000:
traci.simulationStep()
steps+=1
#get the parameters
if(steps == 5):
print(traci.vehicletype.getParameterWithKey("c", "d"))
print(traci.vehicletype.getParameterWithKey("c", "i"))
print(traci.vehicletype.getParameterWithKey("c", "maxSpeed"))
#set the parameters at step 1
if(steps == 10):
traci.vehicletype.setParameter('c', 'depth', '0')
traci.vehicletype.setParameter('c', 'intensity', '0')
traci.vehicletype.setParameter("c", "maxSpeed", '4.00')
Print statements Output is as follows:('depth', '') #parameter name with empty string as value
('intensity', '')
('maxSpeed', '')-------------------------------------------------------------------------------------------------------
Note: There is no change reflected in the sumo-GUI.
Thanks and Regards
