Inquiry about Implementing Traffic Fluid in SUMO with Lane-Free and Custom Vehicle Motion

[xiaofan4122]

Hello everyone,

I am very interested in conducting lane-free traffic simulation using SUMO, particularly exploring the concept of Traffic Fluid. In this scenario, vehicles can be positioned arbitrarily within the road boundaries and may require custom vehicle motion models.

I would like to inquire if there is any existing open-source code or plugins that can help me implement such a simulation environment. If there are no ready-made solutions, how should I begin developing such functionality?

Here are some of my specific requirements and questions:

• Lane-Free Simulation: I need to implement a lane-free environment in SUMO where vehicles can drive at any lateral position on the road.
• Custom Vehicle Motion: I would like to be able to customize the vehicle motion models instead of using the default ones provided by SUMO.
• Open-Source Code: Is there any open-source code or plugins that I can refer to or use directly?
• Development Guidance: If I need to develop it myself, could you provide some suggestions?

I am still at an early stage of researching this issue, and any help or resources would be very valuable.

Thank you for your time and assistance!

• lane-free simulation is possible with the sublane model: https://sumo.dlr.de/docs/Simulation/SublaneModel.html
• custom vehicle models can be implemented in the C++ core (https://sumo.dlr.de/docs/Developer/How_To/Car-Following_Model.html) or via process coupling (https://sumo.dlr.de/docs/TraCI.html)
