The development of autonomous vehicles (AVs) is a transformative advancement in transportation, with the potential to improve safety, efficiency, and mobility. A crucial aspect of this development involves the ability of AVs to navigate complex traffic environments while adhering to traffic laws. This paper presents a simulation framework that enables an autonomous vehicle to learn how to navigate a virtual environment while obeying traffic rules, such as speed limits, stop signs, and traffic signals. The simulation utilizes machine learning algorithms, specifically reinforcement learning (RL), to enable the vehicle to interact with its environment and learn optimal driving behaviours based on feedback. In the proposed framework, a virtual environment is created to model real-world traffic scenarios, including different road types, intersections, traffic signals, and various obstacles such as pedestrians and other vehicles. The simulation is designed to allow the AV to continuously learn from its interactions with the environment, through trial and error, receiving rewards or penalties based on its actions. By using RL, the vehicle is incentivized to develop strategies that not only maximize its own success but also ensure compliance with traffic laws, prioritize safety, and minimize the risk of accidents. The simulation environment incorporates several key features to replicate realistic driving conditions, including dynamic traffic flow, unpredictable behaviours from other road users, and environmental factors such as weather or road conditions. These features enable the AV to encounter a variety of scenarios that it may face in real-world applications. Furthermore, the simulation framework allows for testing and validation of the vehicle’s decision making capabilities in these complex environments before real-world deployment. The reinforcement learning model used in the simulation is trained on a variety of driving tasks such as lanekeeping, turning, stopping at intersections, and yielding to pedestrians. The vehicle is equipped with sensors like cameras, LIDAR, and radar to perceive its surroundings and make informed decisions. The training process aims to optimize the vehicle's ability to make realtime decisions while ensuring it adheres to the rules of the road. The effectiveness of the vehicle’s learning process is evaluated based on its ability to complete tasks without violating traffic rules or causing accidents. Results from initial experiments show that the vehicle, after sufficient training, is able to navigate through diverse traffic scenarios effectively. The simulation indicates that RL can be a powerful tool for teaching AVs to recognize and act in compliance with traffic laws, as well as adapt to changing conditions in real time. Moreover, the ability of the vehicle to anticipate and avoid potential hazards highlights the promising role of simulations in developing autonomous driving systems. However, challenges remain in terms of refining the model to handle edge cases and more complex driving situations, such as aggressive human drivers or unexpected environmental factors. Future work will focus on expanding the simulation environment, improving the learning algorithm, and testing the system under more varied and realistic conditions.
