Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Sight Distance in a Vertical Curve

Sight Distance in a Vertical Curve

Sight distance on vertical curves is critical in roadway design. It ensures drivers can see far enough ahead to identify and respond to hazards effectively. This directly impacts safety, driver comfort, and the overall efficiency of the transportation network.Vertical curves are classified into crest and sag curves based on their geometry. For crest curves, sight distance is determined by the line of sight between a driver's eye and a small object on the road's surface. Design parameters for...

To establish a foundation for understanding built environment influences on pedestrian safety.

Main Methods:

Introduction of a built environment detection task using large-scale panoramic images.
Development of a detection-based pedestrian collision frequency prediction task.
Proposal of a baseline method integrating a collision prediction module into a state-of-the-art detection model for simultaneous task tackling.

Main Results:

Demonstrated a significant correlation between the detection of built environment elements and pedestrian collision frequency prediction.
Established a baseline method capable of addressing both detection and prediction tasks concurrently.
Provided empirical evidence for the interdependencies between built environment conditions and pedestrian safety.

Conclusions:
