Automated Lane Change Strategy using Proximal Policy Optimization-based Deep Reinforcement Learning

Abstract: Lane-change maneuvers are commonly executed by drivers to follow a certain routing plan, overtake a slower vehicle, adapt to a merging lane ahead, etc. However, improper lane change behaviors can be a major cause of traffic flow disruptions and even crashes. While many rule-based methods have been proposed to solve lane change problems for autonomous driving, they tend to exhibit limited performance due to the uncertainty and complexity of the driving environment. Machine learning-based methods offer an altern… Show more

“…To make the energy consumption value as small as possible, we set the sub-reward function to the reciprocal of the above formula: Travel efficiency: velocity, a simple and effective indicator, can be neatly used to represent the transport efficiency (He et al , 2020; Jan et al , 2020). Comfort: jerk , the change rate of acceleration, is regarded as a general indicator to evaluate comfort (Guo et al , 2021; Ye et al , 2020). …”

“…In an early study, Moriarty and Langley [15] use reinforcement learning (RL) to derive lane changing decisions optimizing highway traffic flow. Ye et al [18] let vehicles learn smooth and efficient, collision-free lane change trajectories via RL. Chandramohan et al [5] use Deep Q-Learning to enable an automated vehicle to avoid collisions on a multi-lane highway.…”
