TrafficFluid-Sim is an open source, microscopic simulation tool for lane-free traffic environments in the era of Connected and Automated Vehicles. This project is a fork of Eclipse SUMO - Simulation of Urban MObility and serves as an extension of SUMO that explicitly targets the lane-free traffic paradigm.
Highlighted Features:
- Design from scratch and test lane-free vehicle movement strategies in C/C++, with an API that provides information about the traffic environment, effectively emulating vehicle-to-vehicle and vehicle-to-infrastructure communication.
- Each API function call in the code is accompanied with a concise description of its usage and functionality.
- The underlying movement dynamics of vehicles can be either the double integrator model for both the longitudinal (x) and lateral (y) axis, or a bicycle model that better captures the orientation of the vehicles as well.
- A variety of common traffic environments can be designed and simulated, such as: highways, custom on-ramp and off-ramp scenarios, bidirectional scenarios that can be also tied with emergent infrastructure-based applications such as Internal Boundary Control, roundabouts, intersections, and ring-roads.
TrafficFluid-Sim was developed within the frame of the research project TrafficFluid, an ERC Advanced Grant hosted at the Technical University of Crete.
You can download pre-compiled versions of TrafficFluid-Sim for both Windows 10/11 and Ubuntu 22.04 LTS through our website.
If you want to work with the source code for custom enhancements under Windows environments, as prerequisite for SUMO, please consult our user manual (Section 1.3) and make sure all suggested libraries are installed under the correct versions.
To get started with TrafficFluid-Sim, we provide a complete user manual, including technical information, installation and setup instructions, design guidelines for lane-free traffic scenarios and vehicle movement strategies and more.
Additionally, since this work is an extension of SUMO, we encourage consulting the official SUMO documentation for basic features of the simulator.
TrafficFluid-Sim can be used for research purposes. This codebase is a fork of SUMO, which is licensed under the Eclipse Public License Version 2. The licenses of the different libraries and supplementary code information are in the subdirectories and in the Documentation of SUMO.
