TrafficFluid-Sim

TrafficFluid-Sim is an open source, microscopic traffic simulation tool for automated vehicles driving in lane-free traffic environments in the era of Connected and Automated Vehicles. The simulator is an extension of SUMO that explicitly targets the lane-free traffic paradigm. To this end, the developed codebase is a fork of the open-source code of Eclipse SUMO - Simulation of Urban MObility.

With TrafficFluid-Sim, users can design from scratch and test lane-free vehicle movement strategies in C/C++, with a custom-built API that provides information about the traffic environment, effectively emulating vehicle-to-vehicle and vehicle-to-infrastructure communication. Each provided API function call in the code is accompanied by a concise description of its usage and functionality.

• Introduction of two-dimensional vehicle movement using either of the two movement dynamics:
  • Double integrator model, for both the longitudinal (x) and lateral (y) axis;
  • Bicycle model, with control over the acceleration and orientation of vehicles.
• Implementation for the emerging lane-free infrastructure-based application of Internal Boundary Control.
• Integration of 1-D snake-like vehicle platoons and 2-D deformable vehicle flocks operated as an entity.
• Real-time API export of relevant traffic network measurements.
• Online export of simulation metrics in GUI, along with post-simulation metrics in log files.
• Ability to store and replay scenarios for lightweight execution.
