Hello,
I'm trying to retrieve vehicle lateral speed using TraCI with a python script.
However, I get the below error when I use the method:
C:\Users\xxx\src\sumo-1.2.0\test> python runner.py
Loading configuration... done.
Step #0.05Error: Answered with error to command 0xa4: Get Vehicle Variable:
unsupported variable 0x32 specified
Traceback (most recent call last):

This is my sumocfg file:
<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

</input>
<time>

<lateral-resolution value="0.3"/>
</time>
<processing>
<emergencydecel.warning-threshold value="5"/>
<collision.mingap-factor value="0"/>
</processing>
</configuration>
Any help is appreciated.
Thanks,
Mariam
