- Abstract: Self-driving vehicles must be able to act intelligently in diverse and
difficult environments, marked by high-dimensional state spaces, a myriad of
optimization objectives and complex behaviors. Traditionally, classical
optimization and search techniques have been applied to the problem of
self-driving; but they do not fully address operations in environments with
high-dimensional states and complex behaviors. Recently, imitation learning has
been proposed for the task of self-driving; but it is labor-intensive to obtain
enough training data. Reinforcement learning has been proposed as a way to
directly control the car, but this has safety and comfort concerns. We propose
using model-free reinforcement learning for the trajectory planning stage of
self-driving and show that this approach allows us to operate the car in a more
safe, general and comfortable manner, required for the task of self driving.

We compare two learnable navigation policies: safe and unsafe.
The safe policy takes the constraints into the account, while the other does not.
We show that the safe policy is able to generate trajectories with more clearance (distance to the obstacles) and makes less collisions while training without sacrificing the overall performance.
