Questions tagged [traffic-simulation]

Traffic simulation are an approximate imitation of traffic flow behavior on any road network.

The components or features that are part of traffic simulations are i) Traffic behavior (homogeneous or heterogeneous), ii) traffic flow models (microscopic, macroscopic or mesoscopic), iii) traffic models (such as car following, lane changing) and iv) system (discrete or continuous).

How to program a Byzantine node?

I have a network simulator, and I need to program a Byzantine node class for that simulator. The purpose of these Byzantine nodes is to test the resiliency of an arbitrary networking protocol. Implementing random behaviour would be easy, but not…

Single lane traffic intersection simulation on a given image (or created by matplotlib, cv2, etc)

I want to write python code that simulates single lane traffic intersection on an image that I have below. I don't necessarily need to do it with a given image, ones that are created by cv2, matplotlib, etc are fine as well. The cars start at the…

Sumo departing vehicles on wrong lane

After specifying the departLane, the vehicle still ends up on the wrong path. How do I prevent lane changing so the vehicles stay on the correct path? When the cars try to get into the other lane they hold all the other cars up.

Weird error in SUMO simulation: automatic lane-shifting and vehicle absence

I am working with SUMO traffic simulation and I have 2 unexpected behaviors in my simulation. I declared 6 vehicles in three different types. However, one of the vehicles during simulation changed lanes and 2 vehicles were absent from my simulation.…
