Hi Community,

I am writing this email to ask about how would the step-length value in the sumocfg file would influence the simulation result. I tried two values as below:

Case 1:
<time>
        <step-length value="0.1"/>
 </time>

Case 2:
<time>
        <step-length value="1"/>
 </time>

All other settings are the same. I run simulations using a fixed-time traffic signal controller at an isolated intersection. However, the results under the two cases are significantly different: the average total travel loss of vehicles for case 1 is around 40s but for case 2 is around 80s. From GUI, congestion can be observed under Case 2 but not for Case 1. May I ask you about possible reasons for that? Thank you.

Have a nice day.

Best,
Wangzhi
