[sumo-user] SUMO simulation speed

[Cathy Wu <ca...@ee...>]

Hi everyone,

I am part of a research project at UC Berkeley which requires a traffic
microsimulator that is as fast as possible and implements significant
external control (via TraCI).

I was wondering how I can learn more about the simulation speed of SUMO as
compared with other key simulators (Vissim, Paramics, Aimsun, etc.)? The
following research study states that SUMO may vary from 1-2x real-time
speed (with TraCI calls) to 50x real-time speed (without TraCI calls) for
their small test network.

Blokpoel, R. and Vreeswijk, J. (2015). *Online Micro Modelling Using

> 35–46. Springer International Publishing, Cham.

In comparison, Vissim's website claims 80-160x real-time performance
(without external control), and I believe Aimsun claims 2-3x real-time
performance.

Do you know if other simulators incur a similar performance hit when
implementing external control? I would also like to better understand
why/how TraCI calls cause such a significant performance hit?

We are very excited to be working with SUMO, and look forward to better
understanding its benefits from other simulators!

Best wishes,
Cathy
