Veins is an open source framework for running vehicular network simulations.

Veins is an open source framework for running vehicular network simulations. It is based on two well-established simulators: OMNeT++, an event-based network simulator, and SUMO, a road traffic simulator. It extends these to offer a comprehensive suite of models for IVC simulation. See the official website for further information.

SUMO: Variable Dijkstra Routing Algorithm

SUMO provides four routing algorithms including Dijkstra. Does it uses variable Dijkstra to avoid congestion on new route? Means whenever a vehicle is rerouted, whole network is investigated again to find shortest / fastest path?

OMNeT++ - Veins - Create a scenario of 2 vehicules with a starting position defined

I'm working on Veins | OMNeT++ | SUMO. Is it possible to select the starting position of our cars and the destination? I only see spawn of vehicules at the exact same position and don't know how to adapt them. I've already read some topics…

Is it possible to use SUMO TraCI get the density of the edge?

In order to monitor the LOS (Level of Service) of the edge, I need to know the density of the edge/road. I know the SUMO Edge-based Traffic Measure Output contains the attribute density. But I need to get it during the simulation. So, is it possible…
