Hi Tianli,

 

I don't know why it does not work on your system. Please have a look both "SUMO_HOME" environment variable and whether you have some installed some python module called traci. Please try your script with environment variable "SUMO_HOME" pointing to the latest SUMO release installation and no python module traci installed. You can use our test scenario for TraCI induction loops as well to see whether there is a problem with your script.

 

Best regards

Mirko

I tested these two lines of code separately, and only the above line reported an error.

print("检测器上一时段流量是", inductionloop.getLastIntervalVehicleNumber("e1det_19610445_0"))

print("检测器上一时刻流量是", inductionloop.getLastStepVehicleNumber("e1det_19610445_0"))

And when I hover my mouse over this function, a description like the one below appears.

 

I can't find a solution to this error. So I wonder if there is another way to get the real-time number of vehicles passing the e1 detector.

 

Any help is greatly appreciated.

Thanks and Regards,

Tianli

This sounds strange indeed. The call looks good at first sight. Can you look if by accident you have some control character in the code close/inside this TraCI call? Some text editors do not show control characters by default or hide some...

Hello,

I intend to get the vehicle number of last interval by

traci.inductionloop.getLastIntervalVehicleNumber

But when I ran the following code, an error occured. I wonder if there is a way to solve this error?

  File "G:\xtl\xtl\2023 June\pythonProject\sumo variable lane\sumo.py", line 46, in run    

 print("检测器上一时段流量是", traci.inductionloop.getLastIntervalVehicleNumber("e1det_-15535912_0"))

 AttributeError: 'InductionLoopDomain' object has no attribute 'getLastIntervalVehicleNumber'

Any help is greatly appreciated.

Thanks and Regards,

Tianli
