Tactics2D: A Highly Modular and Extensible Simulator for Driving Decision-making
This addresses the need for a user-friendly tool for researchers and developers in autonomous driving to test decision-making systems in varied scenarios, though it is incremental as it builds on existing simulation concepts.
The paper tackles the lack of flexible and diverse simulators for driving decision-making by introducing Tactics2D, a modular open-source simulator that enables easy construction of traffic scenarios and evaluation of models using public and real-world data.
Simulation is a prospective method for generating diverse and realistic traffic scenarios to aid in the development of driving decision-making systems. However, existing simulators often fall short in diverse scenarios or interactive behavior models for traffic participants. This deficiency underscores the need for a flexible, reliable, user-friendly open-source simulator. Addressing this challenge, Tactics2D adopts a modular approach to traffic scenario construction, encompassing road elements, traffic regulations, behavior models, physics simulations for vehicles, and event detection mechanisms. By integrating numerous commonly utilized algorithms and configurations, Tactics2D empowers users to construct their driving scenarios effortlessly, just like assembling building blocks. Users can effectively evaluate the performance of driving decision-making models across various scenarios by leveraging both public datasets and user-collected real-world data.
