This standard provides a comprehensive overview of the visual aspects involved in driving at night. The report is divided into five chapters, each addressing different aspects of the visual task.

The first chapter establishes the foundational elements of the perceptual process in driving, such as visual attention, detection, recognition, decision-making, and visually guided responses. It also highlights the differences between night driving and daytime operations, focusing on fine and coarse spatial vision, vision near detection, threshold, and color vision in night driving situations.

Chapter two focuses on how the night driver gathers information from the road scene and identifies the important cues required for safe vehicular operation.

Chapter three delves into the sight distances necessary for three key subtasks in driving: maintaining lateral position and heading, avoiding hazards and executing proper maneuvers, and route selection and following.

In chapter four, visibility models and their potential applications are discussed, providing insights into how these models can be used to improve nighttime road visibility.

The final chapter suggests methods for enhancing road design for nighttime conditions. Design elements such as public and vehicular lighting, the use of retroreflective materials, and self-luminous signals are explored.
