frenet_optimal_planner

Implementation of the Frenet Optimal Planning Algorithm (with modifications) in ROS.

The original paper "Optimal trajectory generation for dynamic street scenarios in a Frenét Frame" can be found here

Demo

Features & Modifications

1. We improved the framework to adopt the pipeline used in Apollo Lattice Planner to speed up the planning.
2. We add an asynchronous collision checking module as an option (can be switched on by setting use_async = True), which can significantly improve the planning frequency.
3. We add a trajectory concatenation strategy to keep the trajectories consistent between adjacent planning cycles.
