I've been looking for a decent traffic simulator. Can you modify driver behavior? I am really curious how much traffic could be reduced by changing driver behavior, and simple vehicle modifications. For example, how much time could be saved if at red lights, when the light changes green, if all cars accelerate at the same time and speed, instead of the accordion behavior. This is something basic driver AI could handle and might help with pollution and traffic, while fully autonomous driving is still underway.

Yes, you can change any part of driving behavior you want. Vissim is robust enough that you can even program your own driving behavior if you are so inclined. I have even seen demonstration of hardware-in-the-loop simulations with real autonomous car hardware.

  That actually looks like a fun product, but given that all I saw for finding the price was essentially "contact us", cost is likely very high, and discouraging for just playing around. I wonder why a "SimRoads" hasn't been created? A mashup of this road microsimulation and something like TORCS might be a fun thing to play with, both from the "design" and "simulation" perspectives.

    Yes, Vissim is expensive. It is professional software for a niche market. I don't know the exact cost we pay off the top of my head but it is in the multiple thousands a year for a single seat network license.

    There's a 30 day trial, I might grab that just to play around with.

      If you do play around with it, make sure to take a look at the examples that are included in the installation. They can be found under the Help menu.

Try SUMO (https://sumo.dlr.de/index.html https://sumo.dlr.de/index.html). Microscopic traffic simulator just like VISSIM but free and open source. The dev team is very active on their mailing lists. There is a Python API called TRACI that allows you to change the simulation while it's running. There is also a deep RL framework called Flow (https://flow-project.github.io https://flow-project.github.io) that builds on top of SUMO that shows how autonomous vehicles could potentially eliminate shockwaves in traffic
