A location where roads meet and the driver’s view is obstructed, limiting the ability to see approaching traffic, pedestrians, or cyclists on the intersecting roadway is defined by compromised visibility. Obstructions to sightlines can include buildings, vegetation (such as trees and shrubs), parked vehicles, and terrain features like hills or embankments. This lack of clear visibility significantly elevates the risk of collisions, as drivers have reduced time to react to potential hazards.
These areas present a significant hazard in transportation networks. Understanding the factors that contribute to reduced visibility at roadway junctions is crucial for traffic engineers and urban planners. Historically, these zones have been addressed through various engineering solutions, including adjusting road alignment, removing obstructions, implementing warning signs, and reducing speed limits. These mitigations aim to enhance safety and minimize the potential for accidents.
